What web server software is most popular?

Nginx and Apache are the two most popular web servers, together powering over 60% of websites. Other options include Microsoft IIS, LiteSpeed, and Cloudflare. Each has different strengths for performance and configuration.

Does my web server affect SEO?

The server software itself does not directly affect rankings, but its configuration impacts page speed, security (SSL support), HTTP/2 support, and response codes, all of which influence SEO performance.
