  • On the contrary, if we state the values noindex, nofollow, we’re telling Google that we don’t want these links to be followed or shown in search engines.

Best Practices for Writing Meta Robots Tags

  • Do not confuse noindex tags with robots.txt. With robots.txt files we indicate to a search engine whether we want to crawl some pages or not, while we use robots tags to inform whether a website should be indexed or not.
