Google Ads and PPC Interview Questions and Answers

1. What is PPC, and how does it work?

PPC (pay-per-click) is an advertising model where advertisers pay a fee each time their ad is clicked. It’s a way to buy visits to your site rather than earn them organically. The most common platform for PPC is Google Ads, where ads are displayed based on keyword bidding, ad relevance, and quality score.

2. What are the main types of Google Ads campaigns?

• Search campaigns

• Display campaigns

• Shopping campaigns

• Video campaigns (YouTube)

• App promotion campaigns

• Performance Max campaigns

Each type serves different marketing goals, from awareness to conversion.

3. Explain what a Quality Score is in Google Ads.

Quality Score is a metric that Google uses to evaluate the quality and relevance of your ads, keywords, and landing pages. It’s scored from 1 to 10 and impacts your CPC (cost-per-click) and ad rank. A higher Quality Score can reduce costs and improve ad position.

4. What is Ad Rank, and how is it calculated?

Ad Rank determines your ad position on the SERP and is calculated using

• Bid amount

• Quality Score

• Expected impact of ad extensions and other formats

5. How does bidding work in Google Ads?

Google Ads uses an auction-based system. You set a maximum bid (manual or automated), and Google evaluates your ad rank to determine placement. The actual cost per click is usually lower than your max bid.

6. What are keywords, and how do you choose them?

Keywords are terms users type into Google. You choose them based on

• Search volume

• Relevance

• Competition

• Intent

Tools like Google Keyword Planner, Ubersuggest, and SEMrush help identify effective keywords.

7. What is the difference between broad match and exact match keywords

• Broad Match: Triggers ads for any search containing your keyword, regardless of order

• Phrase Match: Triggers when the query includes the keyword phrase

• Exact Match: Triggers only when the query matches exactly or closely

8. What are negative keywords?

Negative keywords prevent your ad from being triggered by certain words or phrases. They help reduce irrelevant traffic and improve ROI.

CTR (click-through rate) is the ratio of users who click on your ad to the number who saw it. Higher CTR often indicates ad relevance and can improve Quality Score.

11. Explain the concept of conversion tracking.

Conversion tracking allows you to measure actions like purchases, form submissions, or calls that happen after someone clicks your ad. You set it up using conversion tags or Google Tag Manager.

12. What are smart campaigns?

Smart campaigns use automation to simplify Google Ads management for small businesses. They use AI to optimize bidding, targeting, and placement.

13. What is ROAS in Google Ads?

ROAS (Return on Ad Spend) measures the revenue generated for every dollar spent. Formula:
ROAS = Revenue / Ad Spend
Higher ROAS indicates better campaign efficiency.

14. How do you handle low-performing ads?

• A/B test ad copies

• Optimize landing pages

• Adjust keyword match types

• Add negative keywords

• Pause or revise low CTR ads

15. What are Performance Max campaigns?

Performance Max is a goal-based campaign that uses automation and machine learning to serve ads across all Google channels (Search, Display, YouTube, Discover, etc.) using a single campaign.
