IIS is a web server. Site Stats Database detects it on the websites it tracks by analyzing each site's homepage, response headers, and DNS, and has currently found it on 14,679 websites.

Site Stats Database currently tracks 14,679 websites using IIS. That makes it the #4 most common web server out of 16 we detect in this category.

The most common are News, Community, and Funeral sites, and they are most common in United States and Spain. The breakdowns above show the full split across topics, markets, authority, and monetization, based on the 14,679 websites using IIS we track.

IIS is one of 16 web server options Site Stats Database detects. The alternatives section lists the others by adoption, and you can compare IIS head-to-head with any of them.

They tend to have stronger authority than the typical website: the median IIS site has an Ahrefs Domain Rating of 35, higher than the 28 median across all sites Site Stats Database tracks.

Over the last 2 months, the number we track grew 34% and their combined traffic rose 5.2%, based on Site Stats Database's month-by-month snapshots of this group.

Traffic estimates, organic keywords, and authority come from DataForSEO; Domain Rating comes from Ahrefs' public endpoint; and technology detection (including IIS) comes from Site Stats Database's own crawler, which inspects each site's HTML, headers, and infrastructure.

At least monthly. Traffic and rankings refresh every month, and technology detections are refreshed as sites are re-crawled, so this page always reflects the current 14,679 IIS websites.
