How to use this page

These are the questions freshers actually get asked, with answers at the depth interviewers expect — clear, correct, and one level deeper than the definition. If any answer feels shaky, the full course covers every topic here as a complete lesson.

The Basics

1. What is Google Ads and how does it work?

Google Ads is Google’s advertising platform where businesses bid to show ads on Search, YouTube, Maps, Gmail, Display sites and apps. On Search, advertisers bid on keywords; when someone searches, an instant auction decides which ads show and in what order. You mostly pay per click (PPC), not for impressions.

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

SEO earns unpaid rankings in organic results over months and keeps working without per-click cost. Google Ads buys immediate visibility in the ad slots and stops the moment you stop paying. Mature businesses usually run both: Ads for immediate demand capture, SEO for durable traffic.

3. What is Ad Rank and how is it calculated?

Ad Rank decides your ad’s position in the auction. It’s based on your bid, ad and landing-page quality, the Ad Rank thresholds, auction competitiveness, search context, and the expected impact of your assets. A higher-quality ad can beat a higher bid — which is why you can rank above someone paying more.

4. What is Quality Score?

A 1–10 diagnostic rating of keyword quality built from three components: expected CTR, ad relevance, and landing-page experience. Improving those components generally means better positions at lower cost per click, though Quality Score itself is a diagnostic, not a direct auction input.

5. Where can Google ads appear?

Search results (Search campaigns), the Google Display Network of 2M+ sites and apps, YouTube, Gmail, Discover, Maps, and Google Play. Different campaign types serve different surfaces — Performance Max can serve across all of them from one campaign.

Metrics

6. What are CTR, CPC, CPA and ROAS?

CTR is clicks ÷ impressions — how compelling your ad is. CPC is what you pay per click. CPA is cost ÷ conversions — what a customer action costs you. ROAS is conversion value ÷ cost — revenue earned per rupee spent. Together they tell you whether attention is turning into profitable action.

7. What is a good CTR in Google Ads?

It varies by industry and keyword type, but search CTRs of 3–5%+ are commonly considered healthy, and branded terms run far higher. The honest answer interviewers like: compare against your own history and your competitors’ benchmarks, not one universal number.

8. What is the difference between impressions and clicks?

An impression counts every time your ad is displayed; a click counts when someone actually taps or clicks it. CTR connects the two and shows how often visibility turns into interest.

9. What is CPM and when is it used?

CPM is cost per 1,000 impressions. It’s the pricing model for awareness-oriented formats — Display, bumper and non-skippable YouTube ads — where being seen is the goal, versus CPC where you pay for the visit.

10. What is conversion tracking and why does it matter?

It’s the setup (a tag via gtag or Google Tag Manager, or imports from GA4) that reports valuable actions — purchases, leads, calls — back to Google Ads. Without it you can’t judge which keywords or campaigns make money, and Smart Bidding has nothing to optimise toward.

Campaigns & Keywords

11. What are the main Google Ads campaign types?

Search, Display, Shopping, Video (YouTube), App, Demand Gen and Performance Max. Search captures existing intent; Display and Demand Gen build demand visually; Shopping sells products from a feed; PMax runs across all Google surfaces from one automated campaign.

12. What are keyword match types?

Broad, phrase and exact. Broad reaches related meanings widely, phrase requires the meaning of your phrase, and exact matches the same meaning most tightly. Even exact isn’t literal anymore — Google matches by meaning — so negatives and search-term reviews still matter.

13. What are negative keywords and why are they important?

Terms you exclude so your ads don’t show on irrelevant searches — like blocking ‘free’ or ‘jobs’ for a paid service. They cut wasted spend, tighten CTR, and are the main guardrail as match types and AI features widen reach.

14. What is an ad group and how should keywords be organised?

An ad group holds a set of tightly related keywords sharing the same ads and landing page. Organising by theme keeps keyword, ad and landing page aligned — which lifts relevance, Quality Score and conversion rate.

15. What is the Search Terms report?

The report showing the actual queries that triggered your ads — not just the keywords you bought. It’s where you find new keywords to add and junk queries to negate; reviewing it regularly is core account hygiene.

16. What is Google Keyword Planner used for?

Researching keyword ideas, seeing search-volume ranges and bid estimates, and building keyword lists. It’s a starting point for discovery — real performance data from your own search terms is the better long-term guide.

Ads & Landing Pages

17. What is a Responsive Search Ad (RSA)?

The standard search ad format: you supply up to 15 headlines and 4 descriptions, and Google tests combinations to serve the best-performing mix per query. Variety across the assets — different angles, not rewording — is what makes RSAs perform.

18. What are ad assets (extensions)?

Extra elements that expand your ad free of charge — sitelinks, callouts, structured snippets, calls, locations, prices. They make ads bigger and more clickable and feed into Ad Rank via expected asset impact.

19. Why does the landing page matter in Google Ads?

Because the click is only half the job. Landing-page experience is a Quality Score component, and message match, speed, mobile usability and one clear call-to-action decide whether the paid click becomes a customer or a bounce.

20. What is the daily budget and can Google spend more than it?

The average you’re willing to spend per day. Google can spend up to 2× your daily budget on high-opportunity days, but never more than about 30.4× the daily budget in a month — so your true cap is monthly.

Tracking, Audiences & Automation

21. What is remarketing?

Showing ads to people who already visited your site or app — rebuilding contact with warm audiences who didn’t convert. Lists are built from site tags or customer data, and it’s typically among the highest-converting targeting available.

22. What is Smart Bidding?

Google’s automated, auction-time bidding that sets a bid per auction using many signals. The four strategies are Maximize Conversions, Maximize Conversion Value, Target CPA and Target ROAS — volume strategies versus efficiency-to-a-target strategies.

23. What is optimization score?

A 0–100% estimate of how well the account is set to perform, based on Google’s recommendations. Applying or dismissing recommendations both raise it — so treat recommendations as suggestions to evaluate, not orders.

24. What is Performance Max in one line?

A goal-based campaign type that runs across all Google surfaces — Search, Display, YouTube, Gmail, Maps, Discover — from one campaign, using your assets, audience signals and Smart Bidding.

25. A campaign gets clicks but no conversions. What would you check first?

Conversion tracking first — is it firing at all? Then landing-page message match and speed, search terms for junk traffic, and whether the offer and call-to-action are clear. Most ‘no conversions’ cases are tracking or landing-page problems, not bidding ones.

Going deeper?

Interviewers love follow-ups. The experienced-level questions are where they go next — reading them now is the easiest way to stand out as a fresher.
