Brief Explanation of Noindex and Nofollow
How do search engines index?
Search engines have many bots that follow links on your site one by one to crawl and add to the index. Therefore, when doing website SEO, a sitemap is essential.
Google's spider will follow all links on your site, and when someone has a search need, it will search for corresponding content from the index. Articles with no traffic and low quality not only fail to increase site traffic but also waste search engine indexing time, which is not beneficial for SEO.
What is the difference between noindex and nofollow?
noindex and nofollow are implemented by adding meta tags to the page header. Through meta tags, you can clearly tell search engines whether this article should be indexed.

The nofollow attribute instructs search engines to ignore the linked page.
