Google Ads Interview Questions and Answers for Freshers
Q1. What is Google Ads?
A1. Google Ads is Google’s online advertising platform where businesses can promote their products or services through paid ads across Google Search, YouTube, Gmail, Google Maps, and millions of websites in the Display Network.
But here’s what makes Google Ads powerful: it allows advertisers to reach people right at the moment they’re searching for something relevant.
Q2. What are the different types of Google Ads campaigns?
A2. Google Ads isn’t a one-size-fits-all tool. It offers five core campaign types, each suited for different marketing goals:
Search Ads: These appear on top of Google search results.
Display Ads: These are banner or image ads shown across websites.
Shopping Ads: Product listings with image, price, and merchant info (great for e-commerce).
Video Ads: Mostly run on YouTube, ideal for brand awareness and storytelling.
App Ads: Promote mobile apps across Google’s network.
Q3. What’s the difference between SEO and Google Ads (PPC)?
A3. Think of SEO as slow and steady, and Google Ads as fast and targeted.
SEO focuses on ranking your content organically by optimizing your site, creating quality content, and building authority. It takes time — often 3–6 months — to see significant results.
Google Ads, on the other hand, gives immediate visibility. You bid for top placements and only pay when someone clicks.
Example: You want to sell a new fitness product. With SEO, you’d write a blog titled “Best Fitness Trackers in 2025,” and hope to rank in a few months. With Google Ads, you can appear today with a paid ad and test different keywords like “buy fitness tracker online.”
Both are valuable — but if you want leads now, PPC wins.
Q4. What is Quality Score in Google Ads?
A4. Quality Score is Google’s way of rating the relevance and quality of your ads, keywords, and landing pages. It’s scored from 1 to 10, and the higher your score, the better your ad placement — and the lower your costs.
Three main factors affect it:
Expected CTR – Are people likely to click your ad?
Ad Relevance – Is your ad closely related to the keyword?
Landing Page Experience – Is your website useful, fast, and mobile-friendly?
Example: Let’s say you’re running ads for “affordable digital marketing course.” If your ad copy says something generic like “Learn with Us,” your ad relevance drops. But if your ad says “Join Our Affordable Digital Marketing Course – 100% Online,” and your landing page reflects that — your score improves.
Higher Quality Score = Lower CPC + Better Position. It’s a win-win.
Q5. What is CTR in Google Ads?
A5. CTR stands for Click-Through Rate. It tells you how often people who see your ad actually click it. The formula is:
CTR = (Clicks ÷ Impressions) × 100
If your ad had 100 impressions and 5 clicks, your CTR is 5%.
But more importantly, CTR tells Google whether your ad is engaging. A low CTR means your ad isn’t grabbing attention — and Google may reduce your visibility. A high CTR signals relevance, which can improve your Quality Score.
Q6. What are Keyword Match Types in Google Ads?
A6. Match types decide how closely a user’s search must match your keyword to trigger your ad.
Let’s break them down:
Broad Match: The default type. Shows ads on searches that are related, even if not exact.
Phrase Match (“keyword”): Triggers ads only when the exact phrase is present in the user’s query.
Exact Match ([keyword]): Triggers only when the search is very close or identical.
Negative Match (-keyword): Prevents your ad from showing when a certain term is present.
Example:
Your keyword: “online marketing course”
Broad: Shows for “digital promotion classes”
Phrase: Shows for “affordable online marketing course”
Exact: Shows for “online marketing course” only
Using the right match type controls your ad spend and improves targeting.
Q7. What is Ad Rank and how is it calculated?
A7. Ad Rank = Bid × Quality Score + Ad Extensions impact.
It decides where your ad appears on the results page.
Example:
Two advertisers bid ₹50. But one has better ad relevance, higher CTR, and uses sitelinks and callouts. Their Ad Rank is higher—so their ad shows first even with the same bid.
Q8. What are Ad Extensions in Google Ads?
A8. Ad Extensions enhance your ad with extra info like phone numbers, sitelinks, or offers.
Types include:
Sitelink: Extra clickable links
Call: Adds a phone number
Location: Shows map/distance
Callout: Highlights offers (“Free Delivery”)
Structured Snippets: Lists features
Example: A digital agency ad with sitelinks like “PPC Services,” “SEO Plans,” and “Client Reviews” increases CTR and gives users more to explore.
Q9. What is the difference between CPC, CPM, and CPA?
CPC (Cost Per Click): Pay per click—best for traffic.
CPM (Cost Per Mille): Pay per 1,000 views—best for branding.
CPA (Cost Per Acquisition): Pay when a goal is completed—best for leads/sales.
Example:
A lead gen company uses CPA to pay only when someone fills out a form. A brand launch campaign may prefer CPM for maximum exposure.
Q10. What is the Google Ads auction process?
A10. Every search triggers an auction. Google evaluates:
Bid amount
Quality Score
Expected ad performance (extensions, CTR)
It’s not about who pays the most—it’s about relevance and user experience.
Example: A startup with a well-optimized ad and high Quality Score can outrank a big-budget competitor.
Q11. What is a landing page and why is it important?
A11. It’s the first page a user sees after clicking your ad—and it must align perfectly with your ad content.
Example:
If your ad says “Free SEO Webinar,” your landing page must show webinar details immediately—not generic services. A mismatch confuses users and increases bounce rates.
Q12. What is remarketing in Google Ads?
A12. Remarketing targets users who visited your site but didn’t convert.
Example:
A user adds shoes to cart but leaves. Later, they see a Display ad offering “10% Off” for the same shoes—reminding and nudging them to complete the purchase.
Q13. How do you define a conversion in Google Ads?
A13. A conversion is a key action—purchase, signup, call, or app install.
You define what counts as a conversion based on campaign goals and set up tracking to measure it.
Q14. What is conversion tracking?
A14. It tracks actions users take after clicking your ad. You install a code snippet (conversion tag) on the confirmation page (like “Thank You”).
Example:
For an eBook campaign, you track how many users submit their email to download it. That’s your conversion data to optimize from.
Q15. What is the difference between standard and accelerated ad delivery?
Standard: Spreads your budget evenly through the day.
Accelerated: Shows ads as fast as possible until the budget is gone (now mostly deprecated).
Standard is preferred to avoid blowing your budget early in the day.
Q16. What are negative keywords and why are they important?
A16. They block irrelevant search traffic from triggering your ads.
Example:
You sell premium courses. Add “free” as a negative keyword to avoid users looking for free options—this saves money and improves ad quality.

Q17. How do you structure a Google Ads campaign?
A17. Google Ads is Google’s online advertising platform where businesses can promote their products or services through paid ads across Google Search, YouTube, Gmail, Google Maps, and millions of websites in the Display Network.
But here’s what makes Google Ads powerful: it allows advertisers to reach people right at the moment they’re searching for something relevant.
Q18. How do you conduct keyword research for Google Ads?
Q18. Start with your goal: leads, sales, or awareness.
Use tools like Google Keyword Planner, Ubersuggest, or SEMrush.
Analyze competitors.
Look at search intent — is it commercial, informational, or navigational?
Example: For a fitness course, “best online fitness certification” (high intent) is better than “what is fitness” (low intent).
Q19. How do you optimize a Google Ads campaign?
Refine keywords: remove non-performers.
Improve Quality Score.
A/B test ad copies.
Add negative keywords.
Adjust bids by device, location, or time.
Example: If mobile clicks convert better, increase mobile bids by 20%.
Q20. What bidding strategies have you used?
Manual CPC – for tight control.
Maximize Conversions – uses AI to get the most conversions.
Target CPA – keeps cost per acquisition fixed.
Target ROAS – ideal for eCommerce.
Example: For a client selling products online, using Target ROAS helped increase revenue while maintaining profitability.
Q21. How do you use A/B testing in Google Ads?
A21. Create two versions of an ad with different headlines, CTAs, or descriptions. Run both and monitor:
CTR
Conversion Rate
CPC
Example: Testing “Join the #1 Marketing Course” vs. “Get Certified in Digital Marketing Today” might reveal one with a 35% higher CTR.
Q22. What are responsive search ads (RSAs)?
A22. Responsive Search Ads let you enter multiple headlines and descriptions. Google then mixes and matches them to find the best-performing combo.
Example: Add 10 headlines like “Free Demo Available” or “Job-Ready Courses” — Google tests combinations and optimizes delivery based on performance.
Q23. How do you measure campaign success?
ROI or ROAS
CTR and Conversion Rate
CPA (Cost Per Acquisition)
Impression Share
Use Google Ads reports + Google Analytics to get the full picture.
Q24. What is Impression Share?
A24. It’s the percentage of impressions your ads received compared to total eligible impressions.
Low impression share may signal low bids, poor Quality Score, or limited budget.
Q25. How do you use Google Ads Editor?
A25. Google Ads Editor is a free downloadable tool that allows bulk editing of campaigns offline.

A29. You can create segments using:
Website visitors
App users
Uploaded customer data
Interests and behaviors
Useful for remarketing or targeting similar users.
Q30. What is a shared budget in Google Ads?

Q31. How do you reduce CPA?
A31. There are many ways to reduce CPA and that’s are –
Improve Quality Score
Use remarketing lists
Test landing pages
Switch to Target CPA bidding
Q32. What is the difference between first-click and last-click attribution?
First Click: Credits the first interaction.
Last Click: Credits the last interaction before conversion.
Choose based on sales cycle. For awareness, first-click may be better.
Q33. How do you use geo-targeting?
A33. Set ads to appear only in selected locations: by city, radius, zip code.
Example: A local gym may target users within 5 km only.
Q34. What is audience segmentation?
A34. Break your target into groups based on demographics, behaviors, or interests. This helps in creating personalized ads.
Q35. What is dynamic keyword insertion (DKI)?
A35. It lets you insert the user’s search query into your ad text dynamically.

Review disapproved ads
Recheck bidding strategy
Compare keyword trends
Q39. What is Search Impression Share Lost (budget)?
A39. It shows how often your ads didn’t show due to budget limits.
High percentage = increase your budget.
Q40. What is the difference between Google Ads and AdSense?
Google Ads: Advertisers run ads.
AdSense: Publishers show ads and earn revenue.
Q41. What is a Smart Campaign in Google Ads?
A41. Smart Campaigns are automated campaigns designed for small businesses or advertisers new to Google Ads. You only need to set basic parameters like goals, budget, and location — Google automates bidding, targeting, and ad creation using machine learning.
Example: A local gym sets up a Smart Campaign to get calls and foot traffic. Google shows their ad across relevant placements to nearby users searching for fitness services.
Q42. What are Responsive Search Ads?
A42. Responsive Search Ads (RSAs) allow you to input multiple headlines and descriptions. Google then tests different combinations to find the best-performing ad.
Why it matters: RSAs adapt to users’ search behavior, improving CTR and performance over time.
Example: You enter 10 headlines like “Affordable SEO Course,” “100% Online Certification,” “Learn at Your Pace,” etc. Google automatically creates combinations based on what performs best in the auction.
Q43. What is a shared budget in Google Ads?
A43. A shared budget lets multiple campaigns use a single daily budget. Google distributes the spend across campaigns based on performance.
Example: If Campaign A underperforms and Campaign B is generating leads efficiently, more of the shared budget goes to Campaign B. This helps maximize ROI.
Q44. How does bidding strategy impact campaign performance?
A44. Google Ads offers several bidding strategies, including:
Manual CPC
Enhanced CPC
Maximize Clicks
Maximize Conversions
Target CPA
Target ROAS
Choosing the wrong strategy can burn your budget without results. Always align your bidding method with your campaign goal.
Example: For a lead generation campaign, Target CPA may work better than Maximize Clicks because it optimizes for conversions rather than just visits.
Q45. What is the role of Google Ads Editor?
A45. Google Ads Editor is a free offline tool that lets you bulk-edit campaigns. You can:
Make changes offline
Apply bulk edits across accounts
Export/import data
Review before publishing
It’s especially useful for managing large accounts with hundreds of ad groups or keywords.
Q46. What are Portfolio Bid Strategies?
A46. Portfolio Bid Strategies are automated bidding strategies that can be shared across multiple campaigns, ad groups, or keywords.
Example: If you’re managing multiple campaigns for different services, but want all of them to maintain a Target CPA of ₹300, you can apply a single portfolio strategy across them.
Q47. What is Auction Insights in Google Ads?
A47. Auction Insights let you compare your performance with competitors who participated in the same auctions. It provides metrics like:
Impression Share
Overlap Rate
Position Above Rate
Why it matters: This helps you understand who’s beating you and why — so you can optimize accordingly.
Q48. What’s the difference between Target CPA and Target ROAS?
Target CPA focuses on getting conversions at a specific cost.
Target ROAS aims for a specific return on ad spend.
Example: If you sell a ₹5000 course, you might set a Target ROAS of 400% (spend ₹1250 to earn ₹5000). For lead gen, you might set a Target CPA of ₹200 per lead.
Q49. How does geo-targeting work in Google Ads?
A49. Geo-targeting lets you display your ads in specific locations like countries, cities, or even custom radius areas.
Example: A Noida-based coaching center may target only Noida, Ghaziabad, and nearby areas — avoiding wasted clicks from other states.
Q50. What are custom audiences in Google Ads?
A50. Custom Audiences allow advertisers to define their ideal audience based on:
Keywords they search
Websites they browse
Apps they use
Example: For promoting a graphic design course, you can create a custom audience based on users who visit websites like Canva, Adobe, and Behance — targeting users with high intent.
