How does the subtraction of SEO optimization help SEO?
1. Reduce the number of backlinks
In many cases, backlinks are easy to appear due to the need to redo the network operation process, or delete some content, etc. Maybe two or three are no problem, but if the number of backlinks accumulates over time, it will be very difficult. Difficulties are likely to arise.
Usually, if it is a redo, such as changing the reverse link generated by the URL, it is best to do 301 redirection; if a large number of deleted web pages, you can find regular ones, do 301 or directly in robots. Delete the disallow in the txt file, and if there is no rule, you need to classify the backlinks and submit them to the Baidu backlink tool.
2. Reduce the number of multi-channel web pages
I think it means that one page can be browsed through multiple URLs. In fact, there will be no problems with the platform website converted from static pages, but not all programs support static page conversion. For example, fake In a static and dynamic program, one page matches two URLs, and blocking one of them must be done.
3. Reduce the page opening time
This is related to the problem of platform website loading. Platform website loading has a lot to do with the crawling index of spiders.

This may not be a problem for a platform with high popularity, after all, it is all original Webpages are high-quality for search engines, but if there are very few comments on their own, or most news reports have no comments, then it will become a waste page with many blank page comments. It is also easy to solve problems. The reasonable way is to cancel the existence of these pages. If they must exist, they must be disallowed.
5. Reduce low-quality external links
Under normal circumstances, it is normal for the platform website to have spam external links. After all, external links are not under the control of the webmaster, but if the quality of external links is very low or there are many spammy external links , This will have a great impact on the SEO of the platform website, so reducing low-quality external links is a problem that must be paid attention to. In response to this, Google has released a tool for denying links. Baidu seems to have no convenient method for the time being. In addition to manually searching and deleting, at the same time, it is to achieve the effect of trade-offs by adding high-quality external links.
6. Reduce the meaningless crawling of spiders
