To estimate Google's annual search ad revenue for 2020, we can break it down as follows:
-
Estimate the number of Google searches per day in the US: Start with the US population, estimate the percentage of internet users, and then the percentage of those who use Google Search daily. This gives us daily searchers.
-
Estimate the average number of searches per user per day: A typical user might perform a few searches daily.
-
Estimate the percentage of searches that trigger an ad: Not every search results in an ad impression. Consider searches for very common terms or informational queries where ads might be less relevant.
-
Estimate the average cost-per-click (CPC): This is the average amount advertisers pay when a user clicks on their ad. This can vary widely by industry and keyword.
Calculation:
- Total Daily Ad Clicks = (US Population * % Internet Users * % Daily Google Searchers * Avg Searches per User) * % Searches with Ads
- Daily Ad Revenue = Total Daily Ad Clicks * Average CPC
- Annual Ad Revenue = Daily Ad Revenue * 365 days
We would then adjust for 2020, considering potential growth or pandemic-related impacts on search volume and advertising spend.
