🧾 What Is robots.txt and Why Does It Matter?

Search engines follow instructions from the robots.txt file. This file tells them which pages to crawl and which ones to skip. A simple rule can either open up your site or block it from search results.

Most site owners overlook this file. One wrong line can harm your SEO. That’s why testing it is critical.
