Robots.txt for SEO

How to use robots.txt to improve your search engine optimization strategy.

Managing Crawl Budget

Google assigns a crawl budget to every website. If your site has thousands of low-value pages (like filter parameters on an ecommerce site), you should block them in robots.txt so Google focuses on indexing your high-value content.

Avoid Blocking CSS and JS

Modern search engines render pages exactly like browsers do. If you block CSS or JS files, Google cannot understand the visual layout of your page, which can hurt your rankings.
