The reason why the website collection suddenly decreased

1. Baidu update adjustment: every other cycle, Baidu will update the snapshot , just wait for recovery.

2. The website is hacked: In this case, the webmaster needs to check the code himself, kill viruses in time, and develop the habit of backing up every day.

3. Article quality: If the website articles are collected, Baidu may consider them to be worthless content after inclusion, and they will be deleted even if they are included, so originality is still king.

4. Website revision: Generally, websites will be revised or adjusted. As long as it is not a large-scale structural revision such as directory adjustment, URL, etc., it will have little impact on the website and will recover after a period of time.

5. Dead links and wrong links: The codes returned by normal pages are 200 and 301. If there are a large number of 404 pages, Baidu Spider will think that your website is being rectified, and the spider will reduce the number of visits.

Summary: As long as it is a formal optimization method, there is no need to worry if Baidu’s inclusion suddenly decreases, it will recover slowly!
