Many friends who work with Baidu often complain, "My site had thousands of pages indexed by Baidu the day before yesterday. Why is there only the homepage today? The snapshot has also returned to a previous date. Has it been penalized by Baidu? Or is there another reason?" Everyone should have deep experience with Baidu's abnormal indexing. Next, we will talk about how to deal with abnormal situations in Baidu's indexing based on our experience.
Everyone knows that Baidu usually updates every 10-15 days. In this major update, there are always winners and losers. The happy ones see new breakthroughs in their website’s performance during this major update. Those who are worried definitely see no changes in their website's inclusion during this update. Some even more frustrated webmasters find that instead of increasing, their website’s inclusion has decreased significantly, and in severe cases, only the homepage remains. Why does this happen?
**First: How to make your website achieve a miracle in Baidu's big update:**
1. Website content should be updated regularly, preferably daily, maintaining at least 3 updates per week.
2. Once the homepage title is set, do not change it (this is very important; otherwise, the snapshot may roll back).
3. Pay attention to article keywords, descriptions, and keyword density, which should ideally be between 2%-8%.
4. Change 3-6 high-quality friendly links daily.
5. Do not let the number of friendly links on your website exceed 50 (this is very critical; if there are too many friendly links, Baidu may directly reduce your ranking or even "pluck you").
**Second: Why some websites do not increase inclusion or even decrease inclusion during Baidu's update:**
1. Major changes to the homepage title or random modifications (this is very important; if you modify the title more than 5 times within a month, the probability of being K'd by Baidu is 99.99%).
2. A sudden increase in website content overnight, mostly through website collection, commonly known as spam sites.
3. Serious problems with the website's friendly links, such as linking to sites penalized by Baidu.
4. The website contains malicious code, reported by users, leading to Baidu deleting the website's inclusion.
5. Other sites on the same server are penalized by Baidu, affecting your site.
If your website's inclusion is not good, check if any of the above issues apply. If they do, fix them as soon as possible.
