Crawl directives

There are multiple ways to tell search engines how to behave on your site. These are called “crawl directives”. They allow you to:

  • tell a search engine to not crawl a page at all;
  • not to use a page in its index after it has crawled it;
  • whether to follow or not to follow links on that page;
  • a lot of “minor” directives.

We write a lot about these crawl directives as they are a very important weapon in an SEO’s arsenal. We try to keep these articles up to date as standards and best practices evolve.
