Cloudflare is a global CDN, DNS, and security provider that sits in front of a large share of the web. It speeds up sites by caching content at the edge and protects them from attacks and bots. Because it proxies traffic, it is one of the most frequently detected providers in any crawl.

How many university websites using Cloudflare are there?

Site Stats Database tracks 1,305 websites that are both Cloudflare and University, each enriched with traffic, authority, and the full detected tech stack.

They tend to have stronger authority than the typical website: their median Ahrefs Domain Rating is 48, higher than the 28 median across all sites Site Stats Database tracks.

Where does the data come from?

Traffic estimates, keywords, and authority come from DataForSEO; Domain Rating comes from Ahrefs' public endpoint; and the topic, market, and technology detections come from Site Stats Database's own crawler.
