Solution

Incorrect MIME types break resource loading and waste crawl budget. Common issues include .js files served as text/html, images without image/* type, CSS without text/css. Fix server configuration to serve correct Content-Type headers. For Apache use .htaccess, for nginx use mime.types config.
