Especially the webmaster of the website, most of them have this mentality: quickly reach the ideal ranking. So when to optimize and when to keep the ranking stable has become the worry of webmasters, so everyone will try their best to optimize the website, such as seeing a good optimization method on the Internet today, then trying it on their own website immediately, seeing a good optimization method tomorrow, and then modifying the website. The result can only be counterproductive and make Baidu disgusted. Some even pile up a large number of keywords in the page to increase keyword density, or add a large number of external links. You may see the effect in a short time, but as time goes by, Baidu's punishment for you will be more obvious. The previous Wolf Rain SEO is a good example. Don't over-optimize the website. The essence of SEO is to serve SEM for search engines, not to cheat. We must grasp everything. For example, a keyword on your page is bold once, and Baidu knows it is the key, but you bold all the related keywords. What would Baidu think?

2. Baidu's normal update and adjustment

3. The website has undergone major changes, such as revision.

Once the website is revised, the structure of the original website will change, so Baidu will find that your website organization is completely different from before, and it will feel that your website is a bit strange. It is certain that spiders will not visit your station in a short time, but there are also common situations. It is found that the website collection has increased sharply after the revision, but don't be too happy. This increase in website collections is definitely not a good thing to celebrate. So even if you want to modify it, you need to do it step by step in Beijing SEO. This process is best not to be discovered by Baidu. The best thing is to do a good job of 404 pages and classification labels after the website is revised. You can add new categories and tags, but it's best not to delete old content.

4. Server problems

If your website often can't be opened, Baidu Spider will find that it can't be opened for the first time, and it won't be opened for the second time, so a stable server is another key to the development of the website.
