Robots meta tag

The robots.txt file mainly restricts the access of search engines to the entire site or directory, while the robots meta tag mainly targets specific pages. Like other meta tags (such as the language used, page description, and keywords), robots meta tags are also placed on the page, specifically used to tell the search engine robots how to capture the content of this page. The robots meta tag is case-insensitive. Name = "Robots" indicates all search engines. You can enter name = "baiduspider" for a specific search engine ". The content part has four Command Options: Index, noindex, follow, and nofollow. commands are separated by commas. The Index Command tells the search robot to capture the page. The follow command indicates that the search robot can continue crawling along the link on the page. The default values of the robots meta tag are index and follow, except for Inktomi, the default values are index and nofollow.
