Category 1: Google Ads Fundamentals
1. What is Google Ads?
Google Ads is Google’s online advertising platform where businesses pay to show ads across Google Search, YouTube, Display Network, Gmail, Discover, Maps, and partner websites.
In practical terms, it helps businesses reach users when they are searching for a product, comparing options, watching related videos, or browsing online. The biggest advantage is that Google Ads allows advertisers to target users based on intent, keywords, audience behavior, location, device, and conversion goals.
2. How does Google Ads work?
Google Ads works through an auction system. When a user searches on Google, advertisers who are targeting that keyword enter an auction. Google decides which ads appear based on factors like bid, ad quality, landing page experience, expected CTR, ad relevance, and ad assets.
A strong answer in an interview would be:
Google Ads is not only about who pays the most. Google rewards relevant ads and good user experience. So, a well-optimized campaign with a strong Quality Score can sometimes pay less per click and still rank higher than competitors.
3. What are the main types of Google Ads campaigns?
The main Google Ads campaign types are:
- Search Ads — Text ads shown on Google Search results.
- Display Ads — Image/banner ads shown across websites and apps.
- Shopping Ads — Product ads shown for ecommerce searches.
- Video Ads — Ads shown on YouTube and video partners.
- App Campaigns — Ads designed to increase app installs or app actions.
- Performance Max — Goal-based campaigns that run across multiple Google channels.
- Demand Gen Campaigns — Visual campaigns across YouTube, Discover, and Gmail.
4. What is the difference between SEO and Google Ads?
SEO is organic traffic, while Google Ads is paid traffic. SEO takes time but can deliver long-term visibility, whereas Google Ads can generate traffic and leads quickly if campaigns are properly set up.
In interviews, I would explain it like this:
SEO is useful for sustainable long-term growth, while Google Ads is useful for immediate visibility, testing keywords, generating leads, and scaling profitable campaigns. Ideally, both should work together.
5. What is PPC?
PPC stands for Pay-Per-Click. It is an advertising model where advertisers pay only when someone clicks on their ad.
Google Ads is one of the most popular PPC platforms. However, Google Ads can also use other bidding models, such as CPM, CPV, CPA, and ROAS-based bidding depending on the campaign type and objective.
6. What is an ad auction?
An ad auction is the process Google uses to decide which ads appear, in what position, and at what cost. Every time a user searches, Google runs an auction among eligible advertisers.
The result depends on bid amount, ad quality, expected CTR, landing page experience, ad relevance, competition, user context, and expected impact of ad assets.
7. What is Ad Rank?
Ad Rank determines your ad position in the auction. It is calculated using multiple factors including bid, ad quality, landing page experience, expected CTR, ad relevance, auction competitiveness, search context, and expected impact of ad assets.
A practical answer:
To improve Ad Rank, I would not only increase bids. I would improve ad relevance, landing page quality, CTR, and use strong ad assets.
8. What is Quality Score?
Quality Score is Google’s estimate of the quality and relevance of your ads, keywords, and landing pages. It is scored from 1 to 10 and is based mainly on:
- Expected CTR
- Ad relevance
- Landing page experience
A higher Quality Score can help reduce CPC and improve ad position.
9. Why is Quality Score important?
Quality Score is important because it affects CPC, Ad Rank, and campaign efficiency. A higher Quality Score means Google sees your ad as relevant and useful, which can help you get better positions at a lower cost.
In practical campaign management, improving Quality Score often means restructuring ad groups, improving keyword-ad relevance, writing better ad copy, and aligning landing pages with search intent.
10. What is CPC?
CPC stands for Cost Per Click. It is the amount an advertiser pays when someone clicks on their ad.
Formula:
CPC = Total Cost / Total Clicks
For example, if ₹1,000 is spent and the campaign gets 100 clicks, the average CPC is ₹10.
Category 2: Campaign Structure & Strategy
11. How would you structure a Google Ads account?
I would structure the account based on business goals, products or services, locations, and user intent.
A clean structure could be:
- Campaigns by product/service category
- Ad groups by closely related keyword themes
- Keywords grouped by intent
- Ads written specifically for each ad group
- Landing pages matched to ad intent
A good structure improves relevance, Quality Score, reporting, budget control, and optimization.
12. What is the difference between campaign, ad group, keyword, and ad?
- A campaign controls budget, bidding strategy, location, language, and campaign type.
- An ad group contains related keywords and ads.
- A keyword triggers ads based on user searches.
- An ad is the message shown to users.
In simple terms: a campaign is the strategy level, an ad group is the theme level, keywords are the targeting level, and ads are the communication level.
13. How many ad groups should a campaign have?
There is no fixed number. It depends on the product, keyword themes, and account size. The goal is not to create too many or too few ad groups, but to keep each ad group tightly themed.
For example, if I am advertising digital marketing courses, I may create separate ad groups for “SEO course,” “Google Ads course,” and “Social media marketing course” because each has different search intent and ad copy.
14. What is SKAG and is it still useful?
SKAG means Single Keyword Ad Group. Earlier, advertisers used one keyword per ad group for maximum control. But today, because of close variants, smart bidding, and responsive search ads, SKAG is not always necessary.
A modern approach is to use tightly themed ad groups instead of extreme SKAG structures. I would use SKAG only in special cases where a keyword has high volume and high value and requires dedicated messaging.
15. How would you launch a new Search campaign?
I would launch a Search campaign with this process:
- Understand the business goal and conversion action.
- Research keywords based on intent.
- Separate branded, non-branded, competitor, and high-intent keywords.
- Create tightly themed ad groups.
- Write strong responsive search ads.
- Add relevant ad assets.
- Set location, language, audience observation, and budget.
- Set conversion tracking properly.
- Start with a suitable bidding strategy.
- Monitor search terms, CPC, CTR, CPA, and conversion rate.
16. What campaign settings do you check before launching?
Before launching, I check:
- Campaign objective
- Network settings
- Location targeting
- Language
- Budget
- Bidding strategy
- Conversion goals
- Ad schedule
- Devices
- Final URLs
- Tracking template or UTM parameters
- Ad assets
- Negative keywords
- Policy approvals
17. How would you decide the budget for a Google Ads campaign?
I would decide the budget based on business goals, expected CPC, conversion rate, target CPA, and sales value.
For example, if average CPC is ₹50 and we want 500 clicks, the initial test budget should be around ₹25,000. If the conversion rate is 5%, we may get around 25 leads. Then we compare lead quality and CPA with the business target.
18. How do you handle a limited budget?
With a limited budget, I focus on high-intent keywords, exact and phrase match, strong negative keywords, top-performing locations, best devices, and conversion-focused landing pages.
I would avoid broad targeting in the beginning and prioritize keywords that are closer to purchase intent, such as “buy,” “pricing,” “near me,” “demo,” or service-specific keywords.
19. What is the difference between branded and non-branded campaigns?
Branded campaigns target searches related to the company or brand name. Non-branded campaigns target product, service, or category keywords.
Branded campaigns usually have lower CPC and higher conversion rates because users already know the brand. Non-branded campaigns are useful for acquiring new customers and scaling growth.
20. Should we run branded Google Ads if we already rank organically?
Yes, in many cases. Branded ads help protect the brand from competitors, control messaging, promote offers, and dominate search results. They are usually low-cost and high-converting.
However, I would still analyze incrementality. If organic results already capture most branded demand and competitors are not bidding, we can test reducing branded spend.
Category 3: Keywords & Match Types
21. What are keyword match types in Google Ads?
Keyword match types control how closely a user’s search query must match your keyword.
The main match types are:
- Broad match
- Phrase match
- Exact match
22. What is broad match?
Broad match allows ads to show for searches related to the keyword, including synonyms, related searches, and intent-based variations.
It gives the widest reach, but it can also spend budget on irrelevant searches if not managed properly. Broad match works best when paired with strong conversion tracking, smart bidding, and negative keywords.
23. What is phrase match?
Phrase match allows ads to show for searches that include the meaning of the keyword. It gives more control than broad match but more reach than exact match.
For example, the phrase match keyword “digital marketing course” may show for searches like “best digital marketing course online” or “digital marketing course near me.”
24. What is exact match?
Exact match targets searches with the same meaning or intent as the keyword. It offers the highest control, though Google may still match close variants.
Exact match is useful for high-intent, high-performing keywords where I want more control over budget and performance.
25. Which match type is best?
There is no single best match type. It depends on the campaign goal, budget, data, and conversion tracking.
For a new campaign with limited budget, I may start with exact and phrase match for control. Once conversion data is strong, I may test broad match with smart bidding to scale.
26. What are negative keywords?
Negative keywords prevent ads from showing for irrelevant searches. For example, if I sell paid courses, I may add “free,” “jobs,” “PDF,” or “meaning” as negative keywords depending on the campaign.
Negative keywords help reduce wasted spend, improve CTR, improve conversion rate, and protect budget.
27. How do you find negative keywords?
I find negative keywords by reviewing the Search Terms Report, understanding customer intent, checking irrelevant clicks, analyzing competitor terms, and using keyword research tools.
I also create shared negative keyword lists for common exclusions like “free,” “torrent,” “PDF,” “jobs,” “salary,” or irrelevant locations when needed.
28. What is the Search Terms Report?
The Search Terms Report shows the actual queries people searched before clicking an ad. It is one of the most important optimization reports because it helps identify irrelevant traffic, new keyword opportunities, and match type performance.
I use it regularly to add negative keywords and promote strong search terms as exact or phrase match keywords.
29. How do you choose keywords for lead generation campaigns?
For lead generation, I focus on keywords with commercial or transactional intent. These may include terms like “agency,” “consultant,” “services,” “pricing,” “quote,” “demo,” “near me,” or specific problem-based queries.
I avoid very broad informational keywords unless we have a remarketing or funnel strategy to nurture those users.
30. How do you group keywords into ad groups?
I group keywords based on close intent and theme. Each ad group should have keywords that can be served by the same ad copy and landing page.
For example, “Google Ads agency,” “PPC agency,” and “paid ads agency” may be in one ad group if the landing page and messaging match. But “SEO agency” should be in a separate ad group.
Category 4: Ad Copy & Ad Assets
31. What is a Responsive Search Ad?
A Responsive Search Ad, or RSA, allows advertisers to add multiple headlines and descriptions. Google automatically tests different combinations to show the most relevant version to each user.
A good RSA should include keywords, benefits, proof points, offers, CTAs, and different messaging angles.
32. How many headlines and descriptions should an RSA have?
Google allows up to 15 headlines and 4 descriptions. I would usually add as many high-quality variations as possible instead of repeating similar lines.
The goal is to give Google enough variety while maintaining clear messaging, relevance, and compliance with brand guidelines.
33. What makes a strong Google Search ad?
A strong Search ad is relevant, specific, benefit-driven, and aligned with user intent. It should include the primary keyword, a clear value proposition, trust signals, and a strong call to action.
For example, instead of saying “Best Services,” a stronger ad says “Get Certified Google Ads Training | Live Projects + Placement Support.”
34. What are ad assets?
Ad assets are additional pieces of information that can appear with ads. Examples include sitelinks, callouts, structured snippets, call assets, location assets, image assets, price assets, lead form assets, and promotion assets.
Ad assets improve visibility, CTR, and give users more reasons to click.
35. Which ad assets are important for Search campaigns?
Important Search campaign assets include:
- Sitelinks
- Callouts
- Structured snippets
- Call assets
- Location assets
- Image assets
- Price assets
- Promotion assets
- Lead form assets
36. How do you write ad copy for high CTR?
To improve CTR, I write ads that match search intent, include the keyword naturally, highlight a strong benefit, use numbers or proof, address pain points, and include a clear CTA.
For example:
“Hire Certified PPC Experts” is stronger than “PPC Services” because it communicates value and trust.
37. What is ad strength?
Ad strength is Google’s rating of how relevant and diverse your responsive search ad is. It ranges from Poor to Excellent.
However, I would not optimize only for ad strength. I would also monitor real performance metrics like CTR, conversion rate, CPA, and ROAS because an “Excellent” ad is not always the most profitable ad.
38. Should you pin headlines in responsive search ads?
Pinning can be useful when a specific message must appear, such as brand name, legal disclaimer, or keyword headline. But excessive pinning limits Google’s ability to test combinations.
I would use pinning carefully and only when needed for control or compliance.
39. What is a good landing page for Google Ads?
A good landing page should match the ad promise and search intent. It should load fast, be mobile-friendly, have a clear headline, strong CTA, trust signals, relevant content, a simple form, and minimal distractions.
A poor landing page can increase CPC, reduce Quality Score, and lower conversion rate.
40. How do you improve landing page experience?
I would improve landing page experience by making the page relevant to the keyword and ad, improving speed, making it mobile-friendly, adding clear CTAs, reducing form friction, improving content clarity, and adding trust elements like reviews, testimonials, certifications, or case studies.
Category 5: Bidding Strategies
41. What are the main bidding strategies in Google Ads?
Common bidding strategies include:
- Manual CPC
- Enhanced CPC
- Maximize Clicks
- Maximize Conversions
- Target CPA
- Target ROAS
- Maximize Conversion Value
- Target Impression Share
- CPM and CPV for video/display campaigns
42. What is Manual CPC?
Manual CPC allows advertisers to set maximum bids manually for keywords or ad groups. It gives more control but requires frequent monitoring and optimization.
It can be useful for new accounts, small budgets, or when conversion data is limited.
43. What is Maximize Clicks?
Maximize Clicks is an automated bidding strategy where Google tries to get as many clicks as possible within the budget.
It can be useful for traffic campaigns, but for lead generation or sales, I would be careful because more clicks do not always mean better conversions.
44. What is Maximize Conversions?
Maximize Conversions is an automated bidding strategy where Google tries to get the highest number of conversions within the budget.
It works best when conversion tracking is accurate, and the campaign has enough conversion data.
45. What is Target CPA?
Target CPA is a smart bidding strategy where Google tries to generate conversions at or near a desired cost per acquisition.
For example, if the target CPA is ₹500, Google will optimize bids to get conversions around that cost. It works best when the account has enough historical conversion data.
46. What is Target ROAS?
Target ROAS is a smart bidding strategy where Google tries to generate conversion value based on the desired return on ad spend.
For example, a 500% ROAS target means the advertiser wants ₹5 revenue for every ₹1 spent. This strategy is useful for ecommerce or campaigns where revenue tracking is set up correctly.
47. When would you use Target Impression Share?
Target Impression Share is useful when visibility is the main goal, such as brand awareness, competitor defense, or branded search campaigns.
However, I would not use it for performance-focused campaigns unless visibility is more important than CPA or ROAS.
48. When should you switch from Manual CPC to Smart Bidding?
I would switch to Smart Bidding when conversion tracking is accurate and the campaign has enough conversion data. If the campaign is getting consistent conversions, automated bidding can use machine learning to optimize bids by user intent, device, location, time, and audience signals.
49. Why can Smart Bidding fail?
Smart Bidding can fail if conversion tracking is incorrect, conversion volume is too low, goals are unrealistic, budgets are too restricted, or the campaign has poor traffic quality.
For Smart Bidding to work, the data must be clean, and the campaign must have enough learning signals.
50. What is bid adjustment?
Bid adjustment allows advertisers to increase or decrease bids based on factors like device, location, time, audience, or demographics.
However, with many smart bidding strategies, manual bid adjustments are limited because Google automatically adjusts bids in real time.
Category 6: Conversion Tracking & Measurement
51. What is conversion tracking?
Conversion tracking measures valuable actions taken by users after clicking or interacting with an ad. Examples include purchases, form submissions, calls, app installs, bookings, downloads, or WhatsApp clicks.
Without conversion tracking, we cannot properly measure campaign performance or optimize for business results.
52. Why is conversion tracking important?
Conversion tracking is important because clicks alone do not show success. A campaign may get many clicks but no leads or sales.
Proper tracking helps identify which keywords, ads, campaigns, devices, and audiences are generating real business value.
53. What is a primary conversion action?
A primary conversion action is a conversion that is used for bidding and optimization. For example, purchases or qualified leads may be primary conversions.
Secondary conversions are tracked for observation but not used directly for bidding.
54. What is conversion rate?
Conversion rate is the percentage of clicks or visitors who complete a desired action.
Formula:
Conversion Rate = Conversions / Clicks × 100
For example, if a campaign gets 1,000 clicks and 50 conversions, the conversion rate is 5%.
55. What is CPA?
CPA stands for Cost Per Acquisition or Cost Per Action. It shows how much it costs to generate one conversion.
Formula:
CPA = Total Cost / Conversions
For example, if ₹10,000 is spent and 20 leads are generated, CPA is ₹500.
56. What is ROAS?
ROAS stands for Return on Ad Spend. It measures revenue generated for every rupee spent on ads.
Formula:
ROAS = Revenue from Ads / Ad Spend
For example, if ₹10,000 ad spend generates ₹50,000 revenue, ROAS is 5x or 500%.
57. What is attribution in Google Ads?
Attribution explains how credit is assigned to different touchpoints before a conversion. For example, a user may click a Search ad, later watch a YouTube ad, and then convert through a branded search.
Attribution helps understand the full customer journey instead of giving all credit only to the last click.
58. Which attribution model is recommended in Google Ads?
Data-driven attribution is generally recommended when available because it uses account data to assign conversion credit based on actual user behavior.
It gives a more realistic view of how different campaigns, keywords, and ads contribute to conversions.
59. What is enhanced conversions?
Enhanced conversions use hashed first-party customer data, such as email or phone number, to improve conversion measurement accuracy while protecting user privacy.
It helps recover some conversions that may be missed due to browser restrictions, cookie limitations, or cross-device behavior.
60. How would you check if conversion tracking is working properly?
I would check Google Ads conversion status, Google Tag Manager preview mode, Google Tag Assistant, GA4 DebugView, thank-you page firing, event parameters, duplicate firing, and test conversions.
I would also compare Google Ads conversions with CRM or backend lead data to check data accuracy.
Category 7: Optimization & Troubleshooting
61. How do you optimize a Google Ads campaign?
I optimize campaigns by checking search terms, adding negative keywords, improving ad copy, testing landing pages, adjusting budgets, reviewing bidding strategy, analyzing devices and locations, improving Quality Score, and shifting spend toward high-performing keywords and campaigns.
Optimization should be based on business metrics like CPA, ROAS, lead quality, and conversion value, not only CTR or clicks.
62. What would you do if a campaign has high clicks but no conversions?
I would check:
- Search intent and keyword quality
- Search Terms Report
- Landing page relevance
- Page speed and mobile experience
- Form or checkout issues
- Conversion tracking setup
- Audience quality
- Offer strength
- Negative keywords
63. What would you do if CPC is too high?
I would improve Quality Score, use more relevant keywords, refine match types, add negative keywords, improve ad relevance, test long-tail keywords, review competition, improve landing page experience, and adjust bids or bidding strategy.
I would not reduce bids blindly if the keyword is profitable. High CPC is acceptable if CPA or ROAS is strong.
64. What would you do if CTR is low?
Low CTR means the ad may not be attractive or relevant enough. I would improve headlines, include the keyword, test stronger CTAs, use offers, add ad assets, improve ad relevance, and review search terms.
I would also check average position or impression share because poor visibility can affect CTR.
65. What would you do if CPA is too high?
To reduce CPA, I would identify expensive keywords with low conversions, add negatives, improve landing page conversion rate, shift budget to better-performing campaigns, test smart bidding, improve ad relevance, and exclude weak locations, devices, or audiences.
I would also check whether the target CPA is realistic based on CPC and conversion rate.
66. What would you do if impressions are low?
Low impressions may be caused by low bids, limited budget, low search volume, restrictive match types, low Ad Rank, narrow targeting, disapproved ads, or too many negative keywords.
I would diagnose the issue using impression share, keyword status, auction insights, and campaign settings.
67. What would you do if conversions suddenly dropped?
I would check whether tracking is broken, ads are disapproved, budget is limited, landing page is down, competitors increased bids, search demand changed, negative keywords blocked traffic, or recent campaign changes affected performance.
I would compare date ranges and check change history to find the cause.
68. How often should you optimize campaigns?
For new campaigns, I would monitor daily but avoid making too many changes too quickly. For stable campaigns, I would review performance several times a week and make structured optimizations.
The key is to allow enough data before making decisions. Optimization should be consistent but not reactive.
69. What is the learning phase in Google Ads?
The learning phase is the period when Google’s automated bidding system is collecting data and adjusting bids to improve performance. Frequent major changes to budget, bidding, targeting, or conversion goals can reset or disturb learning.
During this phase, I monitor performance but avoid unnecessary changes unless something is clearly wrong.
70. What is A/B testing in Google Ads?
A/B testing means comparing two versions of an element to see which performs better. In Google Ads, we can test ad copy, landing pages, bidding strategies, offers, CTAs, or campaign settings.
A good test should have one main variable, enough data, and a clear success metric such as CPA, conversion rate, or ROAS.
Category 8: Performance Max, Shopping, Display & Video
71. What is Performance Max?
Performance Max is a goal-based campaign type that runs across Google Search, Display, YouTube, Discover, Gmail, Maps, and Shopping inventory from one campaign.
It uses automation, audience signals, creative assets, product feeds, and conversion goals to find users likely to convert.
72. When would you use Performance Max?
I would use Performance Max when the account has clear conversion goals, strong tracking, enough creative assets, and a need to scale across multiple Google channels.
For ecommerce, it can work well with product feeds. For lead generation, I would be more careful and ensure lead quality tracking is strong.
73. What are audience signals in Performance Max?
Audience signals are inputs we give Google to guide the campaign toward the right users. They can include custom segments, remarketing audiences, customer lists, interests, demographics, and search themes.
They do not restrict targeting completely, but they help Google learn faster.
74. What are Shopping Ads?
Shopping Ads are product-based ads that show product image, title, price, store name, and other details. They are mainly used for ecommerce and are powered by a product feed in Google Merchant Center.
Shopping Ads are effective because users can see product details before clicking, which often improves purchase intent.
75. What is Google Merchant Center?
Google Merchant Center is the platform where ecommerce businesses upload and manage product data for Shopping Ads and free product listings.
It includes product titles, descriptions, prices, availability, images, GTINs, shipping, and policy information.
76. What is a product feed?
A product feed is a file or data source containing product information used by Google Merchant Center. It includes details like product ID, title, description, image, price, availability, brand, category, and landing page URL.
A well-optimized product feed can improve Shopping Ads performance.
77. How do you optimize Shopping Ads?
I would optimize Shopping Ads by improving product titles, descriptions, images, pricing, product categories, custom labels, feed accuracy, negative keywords, bidding strategy, and campaign structure.
For ecommerce, I would also segment products by margin, ROAS, category, bestsellers, and inventory status.
78. What is a Display campaign?
A Display campaign shows visual ads across websites, apps, and Google Display Network placements. It is useful for awareness, remarketing, and reaching users while they browse online.
For performance, I would use strong audience targeting, exclusions, frequency control, and compelling creatives.
79. What is remarketing?
Remarketing targets users who have previously visited the website, interacted with the brand, watched videos, or taken certain actions.
It is effective because these users already know the brand and are more likely to convert compared to cold audiences.
80. What is a YouTube Ads campaign?
YouTube Ads allow advertisers to show video ads on YouTube and video partner networks. They can be used for awareness, consideration, leads, sales, and remarketing.
Success depends on strong creatives, clear hooks, audience targeting, and measuring view-through and click-through conversions properly.
Category 9: Practical Scenario-Based Questions
81. A client says Google Ads is wasting money. How would you respond?
I would first avoid assuming and analyze the data. I would check whether conversion tracking is correct, which campaigns are spending, which keywords are converting, search term quality, CPA, ROAS, landing page performance, and lead quality.
Then I would explain clearly:
“Google Ads may not be wasting money overall, but some parts of the account may be inefficient. My job is to identify wasted spend, reduce it, and move budget toward campaigns that generate business value.”
82. If you had 30 days to improve a Google Ads account, what would you do?
- In the first week, I would audit tracking, campaign structure, search terms, landing pages, budgets, bidding, and conversion quality.
- In the second week, I would fix tracking issues, add negatives, pause wasteful keywords, improve ads, and adjust budgets.
- In the third week, I would test landing page or ad copy improvements.
- In the fourth week, I would analyze results and scale what is working.
- The priority would be reducing wasted spend and improving CPA or ROAS.
83. How would you scale a profitable campaign?
I would scale gradually by increasing budget in small steps, expanding high-performing keywords, testing broad match with smart bidding, improving ad assets, expanding locations, creating new landing pages, testing Performance Max, and using remarketing.
I would monitor CPA and ROAS closely because scaling too fast can reduce efficiency.
84. How would you improve lead quality in Google Ads?
To improve lead quality, I would:
- Use high-intent keywords
- Add negative keywords
- Improve ad messaging to pre-qualify users
- Ask qualifying questions on lead forms
- Import offline conversions from CRM
- Optimize toward qualified leads, not just form fills
- Exclude poor-performing locations or audiences
85. How would you handle a client with unrealistic CPA expectations?
I would explain CPA using data. For example, if CPC is ₹100 and landing page conversion rate is 5%, the expected CPA is around ₹2,000. To reach a ₹500 CPA, we would need either a much lower CPC, much higher conversion rate, or better targeting.
86. What would you do if the client has a small budget but wants fast results?
I would focus only on the highest-intent campaigns first. I would avoid broad awareness campaigns and prioritize exact/phrase match Search campaigns, strong negative keywords, conversion tracking, and a focused landing page.
With a small budget, the goal is not maximum reach. The goal is efficient spending and quality leads.
87. How do you decide whether to pause a keyword?
I would not pause a keyword only because it spent money. I would check clicks, cost, conversions, CPA, conversion value, search terms, and assisted value.
If a keyword spends significantly without conversions and shows poor intent, I would pause it or reduce bids. If it is strategically important but underperforming, I may test new ads or landing pages first.
88. How would you explain poor performance to a client or manager?
I would explain poor performance with facts, not excuses. I would show what changed, where performance dropped, possible reasons, and what actions are being taken.
For example:
“CPA increased because CPC rose by 20% and conversion rate dropped on mobile. We are reducing spend on weak mobile traffic, testing a faster landing page, and adding negative keywords from the latest search terms.”
89. What is your checklist before increasing budget?
Before increasing budget, I check:
- Campaign is profitable or near target CPA/ROAS
- Conversion tracking is accurate
- Search terms are clean
- Impression share shows room to grow
- Budget is actually limiting performance
- Landing page can handle more traffic
- Lead or sales quality is acceptable
90. What would you say if asked: why should we hire you for Google Ads?
“You should hire me because I understand Google Ads as a performance channel, not just a platform for getting clicks. I focus on business outcomes like qualified leads, sales, CPA, ROAS, and revenue. I know how to structure campaigns, analyze search intent, reduce wasted spend, improve ad relevance, and optimize based on data. My approach is practical: track correctly, test systematically, and scale what works.”
