The most important thing in SEO is external links. We usually spend a lot of time on links, but after a while we find that many of them no longer exist. When we use SEO tools to query, there are only a pitiful few. This Does the problem get our attention? Everyone also knows that search engines have an inspection period for external links. If a certain period of time is not reached, the weight of the link will not be calculated. This means that our hard work has been in vain. So what is the reason? Come on one by one below.
Search engines are constantly adjusting
The number of web pages on the Internet is huge. Search engines are working all the time, and the work they face is also huge. Faced with massive amounts of data and content, search engines need to screen and delete those that are of no value to users and are highly repetitive. , and if these contents contain our external links, the links will be deleted, so they will not be counted in the effective weight.
The failure of some link baits
Link bait is an important way for us to obtain external links, but not all link bait can be stored for a long time. For example, if your specialty is making website templates, many people use your templates, so within a certain period of time, your Websites should rely on these templates to obtain good external links, but after a period of time, some users will delete these links, and some websites no longer exist, so these links no longer exist. This is also a core factor. Some are news link baits, and some are resource link baits. As time goes by, these may be deleted.
Forum posts included were deleted
Forum posting is a method often used by most webmasters. This method is very effective. For example, Chinaz is a very good platform. In order to ensure the effect, Chinaz’s signature cards are only available for a limited time, which has led to many webmasters to post External links, but the problem lies in the content. As you can see, many webmasters post only one sentence, or even answer a few words. It is very simple. Such content is indeed original and may also be included. , but many are only temporary. After inclusion, it will also be deleted by search engines. Therefore, when you publish again, you must publish original content, and it is best to have a slightly longer word count.
Caused by changes in the platform
Another common method is to build external links on the platform, such as the friendly link platform, Baidu Library, etc. Some time ago, Baidu Library was involved in copyright incidents, resulting in many documents being deleted. There are many external links in these documents, so It will have a certain impact on the website. Another example is some friendly link exchange platforms. You may be able to make links at the beginning, but later when the webmaster discovers them, they will block them. There are also some webmasters who use blog groups to create links, but in the end they find that the blog has been K-ed or demoted, and the external links in the blog will also become invalid.
After reading the above reasons, I believe that the webmaster must understand why it disappeared. Some of the reasons here are caused by ourselves and can be solved well. Especially when posting on the forum, we can post some original content that is valuable to users. Much more useful than posting some reprints. But there are also some things that we can’t control ourselves. Don’t pay too much attention at this time. The correct approach is to continuously update external links so that the website can obtain continuous new content.
