Yesterday, I did some SEO details on the blog, mainly to adjust the weight of the pages in the site.
A large number of them use the nofollow attribute. I wrote this SEO analysis and reported it to everyone.
Setting the nofollow attribute can tell search engine spiders not to adopt or follow this link. For example, <a href=”http://www.seodw.com” rel=”nofollow”> means that the link will not be assigned any weight. Search engine spiders will not crawl and crawl along this link. We usually use nofollow to control the loss of page weight, which is common in highly interactive websites such as personal blogs and forums. This point has been mentioned in "Three Knowledges That SEO Must Master". In addition to blocking external links, nofollow can also be used to distribute weights. It's easier to handle if you know this.
First of all, the latest comments on my homepage, author introduction and other relatively minor page links have added the nofollow attribute. The archive time and other lists were simply moved to the category page (channel page).
Except for friendly links, all external link references have added the nofollow attribute. This needs to be emphasized. In theory, nofollow only prevents the loss of page weight, but search engines such as YAHOO will still regard these nofollowed URLs as External links to the target website are displayed. This is highly commendable and is beneficial to both people and ourselves. Compared with script calling or redirection, it is more user-friendly.
For links in the footer or header file, such as sitemap.html, if necessary, you can set nofollow separately on the category and content pages. After all, it is only for index collection and user-friendly browsing. It is somewhat redundant to allocate links to the entire site.
In addition, many people in the SEO community believe that search engines will give extra weight to a website or webpage that often uses the rel=nofollow attribute. Maybe it complies with the privacy protection agreement? I don’t know the truth, but nofollow is an indispensable weapon in SEO, and we all need it
Good at application.
