What Makes a High-Rating robots.txt File?

1. Always Declare Your XML Sitemap

Search engine crawlers read /robots.txt before anything else on your domain. Including Sitemap: https://yourdomain.com/sitemap.xml guarantees that Googlebot, Bingbot, and AI search engines find all of your indexable pages immediately.

2. Never Block CSS or JavaScript

Google renders pages using a headless Chromium browser. If your robots.txt blocks *.css, *.js, or /wp-includes/, Googlebot cannot verify mobile responsiveness and may downgrade your rankings.

3. Use Robots.txt for Crawl Budget, Not De-Indexing

Blocking a URL with Disallow: prevents bots from crawling the page, but Google can still index the URL if external links point to it. To remove a page from search results, allow crawling and use a <meta name="robots" content="noindex"> tag instead.
