Google Ads Interview Questions – 40 Questions and Answers for Freshers (2026)

Google Ads interviews feel different from SEO interviews. There’s real money involved, so the interviewer wants to know one thing above all: will this person waste our budget?

That’s why the questions quickly move from “What is CPC?” to “What would you do if…”. You’ll get the definitions right if you’ve studied. The scenario answers come from actually running a campaign, even a small one with ₹500.

The 40 questions below are in 7 sections, from basics to advanced. Use them to revise, then practise saying each answer out loud with an example.

Section 1: Google Ads Basics

1. What is Google Ads?

Google’s advertising platform. Businesses pay to show ads on Google Search, YouTube, Gmail, Google Maps and partner websites and apps. On Search, you usually pay only when someone clicks, which is called pay-per-click (PPC).

2. What is the difference between SEO and Google Ads?

SEO earns free organic rankings over time. Google Ads buys instant visibility, and you pay for every click. Ads are fast and easy to control. SEO is slower but keeps working without per-click costs. Most businesses benefit from both. Our post on SEO vs Google Ads explains when to use which.

3. What campaign types does Google Ads offer?

Search, Display, Video (YouTube), Shopping, Performance Max, Demand Gen and App campaigns. For lead generation, freshers mostly work on Search and Performance Max.

4. How is a Google Ads account structured?

Account → Campaigns → Ad groups → Ads and keywords. Budget, location and bidding are set at campaign level. Each ad group should hold a tight theme of keywords with ads written for that theme.

5. What are CPC, CTR and CPM?

CPC (cost per click) is what you pay for each click. CTR (click-through rate) is clicks ÷ impressions. CPM (cost per mille) is the cost per 1,000 impressions, mostly used for Display and Video. Our CPC calculator and CTR calculator help you practise these.

6. What are CPA, conversion rate and ROAS?

CPA (cost per acquisition) is spend ÷ conversions, often called cost per lead. Conversion rate is conversions ÷ clicks. ROAS (return on ad spend) is revenue ÷ ad spend. ROAS of 4 means ₹4 revenue for every ₹1 spent.

7. What is the Google Ads auction?

Every time someone searches, Google runs a quick auction among advertisers whose keywords match. It decides which ads show, in what order, and what each advertiser pays. The highest bid doesn’t automatically win. Ad Rank does.

Section 2: Keywords and Match Types

8. What are the keyword match types?

Broad match shows ads for searches related to the keyword’s meaning. Phrase match (in quotes) shows ads for searches that include the meaning of the phrase. Exact match (in square brackets) shows ads for searches with the same meaning or intent. Broad match modifier was retired in 2021. Saying so shows you’re current.

9. When would you use broad match?

When you use Smart Bidding with good conversion tracking and enough conversion data, so Google can learn which searches convert. With a small budget and no conversion data, broad match can waste money on irrelevant searches, so start with phrase and exact.

10. What are negative keywords?

Words that stop your ad showing for certain searches. A paid course might add “free”, “jobs”, “salary” and “pdf” as negatives. They’re one of the quickest ways to cut wasted spend.

11. What is the search terms report?

A report showing the actual searches that triggered your ads, not just your keywords. You review it regularly to add good searches as keywords and bad ones as negatives.

12. How do you do keyword research for a campaign?

Start with the business’s services in customers’ words, then use Google Keyword Planner for volumes and suggested bids. Group keywords by intent into ad groups, pick match types, and prepare a starting negative keyword list before launch.

Section 3: Quality Score, Ad Rank and Ads

13. What is Quality Score?

A 1–10 rating Google gives each keyword. It’s based on expected CTR, ad relevance and landing page experience. It’s a diagnostic tool, not a direct input into the auction, but the same factors affect your ad’s position and cost.

14. How do you improve Quality Score?

Keep ad groups tightly themed, use the keyword in the ad headlines, write ads people want to click, and send traffic to a fast landing page that matches the ad’s promise. Our landing page checklist covers the landing page side.

15. What is Ad Rank?

The value that decides your ad’s position and whether it shows at all. Google bases it on your bid, ad quality, Ad Rank thresholds, the search context (device, location, time) and the expected impact of your assets.

16. What is a responsive search ad (RSA)?

The standard Search ad format. You give up to 15 headlines (30 characters each) and up to 4 descriptions (90 characters each), and Google tests combinations to find what works. You can’t create the old expanded text ads anymore.

17. What is ad strength?

A rating from “Poor” to “Excellent” for responsive search ads, based on how many unique, relevant headlines and descriptions you’ve added. It’s a helpful guide but not a ranking factor. Better performance matters more than the label.

18. What are assets (ad extensions)?

Extra information added to ads: sitelinks, callouts, call buttons, location, structured snippets, images, lead forms and more. They make ads bigger and more useful, and usually improve CTR. Google renamed extensions to “assets”.

19. What is pinning in responsive search ads?

Fixing a headline or description to a specific position, for example always showing the brand name as headline 1. It gives control, but pinning too much reduces Google’s ability to test combinations.

Section 4: Bidding and Budget

20. What bidding strategies are there?

Manual CPC, Maximise clicks, Maximise conversions, Maximise conversion value, Target CPA, Target ROAS and Target impression share. The conversion-based ones (Smart Bidding) use machine learning to set a bid for each auction.

21. Which bidding strategy would you use for a new account?

A reasonable answer: start with Maximise clicks or Manual CPC with a bid cap to gather data, set up conversion tracking from day one, then move to Maximise conversions once conversions are coming in, and to Target CPA after you have enough of them. The exact path depends on budget and data.

22. What is Target CPA?

A Smart Bidding strategy where you tell Google the average cost per conversion you want, and it adjusts bids to get as many conversions as possible around that target. Setting the target far below what you’re currently achieving usually reduces volume sharply.

23. What is the learning period?

After you launch Smart Bidding or make big changes, Google needs time to learn, often around a week or more depending on conversion volume. Performance can be unstable during this time, so avoid changing things every day.

24. How do you decide a daily budget?

Work backwards: target leads per month × expected cost per lead ÷ 30. If you want 60 leads at ₹300 each, that’s ₹18,000 a month or about ₹600 a day. Google can spend up to twice the daily budget on some days, but it won’t go over the monthly limit (about 30.4 × daily budget). Our Google Ads budget calculator does this maths.

25. What is impression share?

The percentage of impressions you actually got out of all you were eligible for. “Lost impression share (budget)” means the budget ran out. “Lost impression share (rank)” means Ad Rank was too low.

Section 5: Conversion Tracking and Measurement

26. How do you set up conversion tracking?

Either add the Google Ads conversion tag (usually through Google Tag Manager) on the thank-you page or form submit, or import key events from GA4. Track calls from ads and website clicks on phone numbers and WhatsApp buttons as well. Always test it with a real submission.

27. Why is conversion tracking so important?

Without it, you can’t tell which keywords and ads bring leads, and Smart Bidding has nothing to optimise for. Optimising for clicks without tracking leads is the most common way small accounts waste money.

28. What is enhanced conversions?

A feature that sends hashed customer data from your forms, such as email or phone, to Google so it can match more conversions to ad clicks. It improves measurement accuracy, especially when cookies are limited.

29. What is offline conversion import?

Uploading results that happen outside the website, such as which leads actually joined the course, back into Google Ads. Bidding can then optimise for real sales instead of every form fill, including the junk ones.

30. Which metrics would you report to a client every week?

Spend, clicks, conversions, cost per conversion, conversion rate and, for e-commerce, ROAS. Add a short note on what you changed and what you plan next. Business owners care about leads and cost per lead, not impressions.

Section 6: Scenario-Based Google Ads Questions

31. The cost per lead doubled this month. What would you check?

First check that conversion tracking still works. Broken tracking looks exactly like a performance drop. Then compare CPC, CTR and conversion rate to last month to see which one moved. Check the change history for recent edits, the search terms report for new irrelevant searches, auction insights for new competitors, and whether the landing page changed or slowed down.

32. The ads get lots of clicks but almost no leads. What would you do?

Look at the search terms report for irrelevant searches and add negatives. Check that the ads aren’t attracting the wrong people, for example job seekers searching for “digital marketing jobs” when you sell a course. Then test the landing page on mobile: message match, form length, speed and a visible call button.

33. The budget runs out by noon every day. What are your options?

Check whether the morning clicks convert. If they do, ask for more budget. If not, lower bids, narrow keywords and add negatives, use an ad schedule to show ads at the best-converting hours, or narrow the location targeting.

34. A client wants to rank #1 on every keyword. How do you respond?

Explain politely that being first on every search can cost far more without bringing more leads. Show data on cost per lead by position, and suggest targeting the top positions only on the highest-converting keywords.

35. Your ad was disapproved. What do you do?

Read the policy reason shown in the account. Fix the issue, whether it’s in the ad text, the landing page or the destination, then edit the ad, which sends it for review again. If you believe it’s a mistake, you can appeal from the policy manager.

36. How would you set up a campaign for a local institute with ₹20,000 a month?

One Search campaign, targeting a radius around the institute, with tightly themed ad groups (main course, fees, weekend batch), phrase and exact match keywords, a strong negative list, responsive search ads, call and location assets, a focused landing page, and tracking for forms, calls and WhatsApp clicks. Start with Maximise clicks with a bid cap, then switch to Maximise conversions once leads come in. Read more in our guide to Google Ads for local businesses.

Section 7: Advanced Questions

37. What is Performance Max?

A goal-based campaign type that runs across all Google channels (Search, YouTube, Display, Gmail, Maps, Discover) from one campaign, using your assets and conversion goals. It needs good conversion tracking and quality assets to work well. Our Performance Max guide explains it in detail.

38. What is remarketing?

Showing ads to people who already visited your website or app, or interacted with your YouTube channel. They already know you, so they usually convert better than new visitors.

39. What is an A/B test in Google Ads?

Testing one change against the original to see which performs better, such as a new headline, landing page or bidding strategy. Google Ads has built-in experiments that split traffic fairly. Change one thing at a time and wait for enough data. Our A/B test calculator checks whether a result is significant.

40. What is consent mode?

A Google setting that adjusts how tags behave based on whether a visitor accepted cookies. For users who decline, Google uses modelling to estimate conversions. It matters most for advertisers targeting the EU and UK.

How to Prepare for a Google Ads Interview

• Run one real campaign. Even ₹500–1,000 on a local business or your own blog teaches you more than a week of videos. Screenshot the results.
• Get the free Google Ads certification. It shows you’ve covered the basics. See how to get Google Ads certified for free.
• Learn the terms properly. Our Google Ads glossary has 80 terms with examples.
• Practise the maths. CTR, CPC, CPA, conversion rate and ROAS. Interviewers often give you numbers and ask you to calculate one.
• Answer scenarios in order. Tracking first, then data, then changes, then measurement.

Frequently Asked Questions About Google Ads Interviews

What questions are asked in a Google Ads interview for freshers?

Freshers are usually asked about account structure, CPC, CTR and CPA, keyword match types, negative keywords, Quality Score, Ad Rank, responsive search ads, bidding strategies, conversion tracking, and one practical scenario like rising cost per lead.

Is the Google Ads certification enough to get a job?

It helps you get shortlisted, but it’s rarely enough on its own. Employers want to see that you’ve actually built and managed a campaign. One small live campaign with results is a big advantage.

What is a good CTR in Google Ads?

It depends on the industry and keyword. For Search campaigns, many accounts see a few percent, and branded keywords often get much higher. In an interview, say that you compare CTR against the account’s own history and competitors rather than one fixed number.

How do I explain Quality Score in an interview?

Say it’s a 1–10 rating per keyword, based on expected CTR, ad relevance and landing page experience. Add that it’s a diagnostic, and that improving those three things also improves Ad Rank and can lower CPC.

Should I learn Meta Ads along with Google Ads?

Yes. Most agency roles in India ask for both. Google Ads captures people already searching, while Meta Ads creates demand on Facebook and Instagram. Knowing both makes you more useful from day one.
