Recently, I went back to check the external chain situation last year and found that many of the previously included external chains had been deleted. Although it is a normal phenomenon for external links to be deleted after inclusion, if a large number of external links are deleted, you need to find out the reasons for the deletion and solutions. So I integrated all the external links that were deleted after inclusion and looked at them. They were basically forum-type external links. So I made a detailed analysis of the reasons why the forum posts were deleted.
1. There are a lot of posts on the forum every day, and the number of posts included by search engines is certain. If search engines include new posts every day, then there will inevitably be corresponding posts with poor quality deleted by the search engines. Someone will definitely ask,"How much is the forum included?" This is determined by the weight of each forum. The search engine has its own judgment system to determine the weight of the forum. Generally, the survival rate of posts on high-weight forums will be higher, but no matter how powerful you are, your posts will be deleted. Therefore, this situation cannot be eliminated. We can only reduce this possibility and find ways to make our posts survive longer.
2. Search engine database. Although Baidu's database is huge, its database is definitely limited. Search engines grab a lot of new information every day. In order to ensure the normal and rapid operation of the search engine database, the database needs to clean up some data information every day, so that long-term and poor quality content will be cleaned up. Therefore, our external chains need to be constantly updated, so that even if some of our external chains are lost every day, we have new external chains added. In this way, there will be no decline in website weight and keywords due to the loss of external links.
3. The quality of the post content. Because of the large number of external links in the forum that were deleted, we looked at the posts and found that many of the posts were of low quality. They were all bad information posted online. Moreover, many of the posts in the forum were posts with no actual content or significance. Such posts can easily be sunk. After time, they will either be deleted by the moderator or directly deleted by the search engine. Therefore, the quality of posts is very important. Make sure that the posts are accessible to others. It is not enough for people to read the posts. Your posts need to arouse an interaction so that more people can participate in the reply. This way, the popularity of the posts is high. It will be turned into hot posts, may become elite posts, or be recommended by moderators. In this way, the quality of your posts will increase and your life cycle in the forum will be longer. There are also easy-to-understand forum posts that must be selected from the moderator, or some posts that may become hot posts. When replying, they must be on the first page and appear on the first few floors as much as possible. Because Baidu generally only includes the first few of the first page, you must return to the first few floors in order to ensure that your replies are included by Baidu.
In fact, it is a very normal phenomenon for a collection to be deleted, so don't worry, but if too many appear, you will have to adjust the external chain ideas and plans. Like what I did before, I did too much on the forum, which led to this situation happening now. I hope everyone will not make the same mistake as me. Don't put all eggs in one basket. Our external chain also needs to be in multiple forms and balanced. Don't just keep doing whatever is easier to do. The easier it is to do, the lowest weight is and the fastest you can delete it.
