Suggested Approach

Break down Google Ads revenue into its main components: search, display, video, and other formats. Estimate the number of advertisers, average spend per advertiser, and then sum across formats. Use a top-down or bottom-up approach, stating assumptions clearly and sanity-checking against known figures like Google's total revenue.

Pro tip: Anchor your estimate to Google's total revenue (e.g., ~$280B in 2023) and note that ads constitute ~80% of it. This shows you understand the business context and can validate your answer.

1. Clarify scope and assumptions

Define what 'Google Ads' includes (Search, Display, YouTube, etc.) and whether it's global or regional. State any assumptions about time period and currency.

2. Segment by ad format

Break down revenue by major ad formats: Search, Display, Video (YouTube), and others. Estimate the proportion of revenue each contributes based on industry reports or logical reasoning.

3. Estimate for each segment

For each format, estimate the number of advertisers and average annual spend. Alternatively, use a top-down approach: start with Google's total revenue and allocate to Ads.

4. Sum and sanity-check

Add up the segment estimates to get total Google Ads revenue. Compare with known public figures (e.g., Alphabet's 10-K) to validate your answer.

  • Major ad formats: Search, Display, YouTube, and others
