Search Engine Referral Report for 2022 Q3

Cloudflare finds itself in a position where it can reliably estimate the search engine market share. These reports are produced quarterly and each covers a group of search engines broke down by client location and operating system. The strategy we use relies on the referer header we see when we get an HTTP/S request.

Our goal is to determine the market share of general search engines around the world.

Cloudflare accelerates and protects traffic for large parts of the Internet, with a global network that spans more than 200 cities in over 100 countries. Approximately 25 million Internet properties rely on Cloudflare's network to reach their audiences. More than 10% of all websites connect through our reverse proxy, including 17% of the Fortune 1000.

Due to the size of our network we are in a unique position to measure statistically relevant market share data.

Our methodology uses the referer header. Whenever a link is clicked from a given search engine, that search engine is identified by this header. For this analysis, we only use the referer origin, and not any referer paths or query strings.
