The “nofollow” tag is a tag attribute in the code. Links on the webpage will not be weighted after adding this tag. Search engines support the nofollow attribute. In other words, the link with the nofollow tag attribute is used to tell search engines not to follow this link, don’t pass the link weight, and don’t calculate this link in the search algorithm.
In website SEO optimization, by setting the nofollow tag, we can control the flow of website weights (that is, often called “centralized weights”) and avoid links pointing to spam pages, so that the main pages of the website can be obtained faster The keywords are ranked.
However, it should be noted that if there are links on other pages that you want to nofollow, for example: nofollow is added to the home page, but nofollow is not added to the inner page, or the page link directly submitted by the sitemap, the crawler will still crawl. The attitude of the current page to the target page does not represent the attitude of other pages towards the target page. In addition, the nofollow tag is targeted at search engine spiders and does not affect user clicks for users.So don’t worry if it will affect the user experience.
