Here’re the common issues in Baidu SEO and how to fix that with right solutions.

1. Indexation becomes 0

At first, Baidu included your website normally, but suddenly the number of website inclusions was zero. In most cases, the website is punished by Baidu. How to solve it?

• Check the website code, whether there is a link, and link to the unlisted website.
• Check the increasing frequency and speed of external links on the website to avoid a large increase in the number of external links in a short period of time.
• Use spider crawling simulation to test whether spider crawling is smooth.
• Check if the hosting performance is stable.

2. Cached has not been updated

The problem of website snapshot update has always been a particular headache for us, because no one knows when the spider crawls the website. The snapshot is not updated, which proves that the spider has not updated the web page information in its database.

• Check the website code and delete the code that is not conducive to spider crawling, such as JS code.
• Check if the hosting performance is stable.
• Improve the quality of external links.
• Complaint to Baidu Center.

3. Website security issues

In website optimization, website security is also a difficult problem in SEO optimization. If the website is not secure, then the management authority can easily fall into the hands of hackers, resulting in the implantation of Trojan horse programs and links.

• Restrict write permissions to template directories and files as much as possible.
• The website must have a system backup, and check the website for abnormal problems included in the website every day.
• Frequently upgrade the website program, or download the upgrade patch to the official website.

4. The weight of the website is reduced

Most websites have experienced reduced weights. Downgrading is one of the most critical issues in website optimization, because once the right is downgraded, all keyword rankings, website traffic, inclusion and snapshots will be affected. This will wipe out the previous efforts. Moreover, it is difficult to restore the website after proper adjustments.

• Ensure the stability of hosting, because the instability of the space is also a key factor in the reduction of the website.
• Modify the website code and delete some content that is unfavorable to search, such as deliberately adding H1 tags, website redirects, etc.
• Increase the external links of the website, and try to diversify the anchor text keywords of the external links.
• Do a good job of 301 redirects and 404 page guidance to reduce website weight dispersion and user bounce rate.
• Remove low-quality links.

The above points are the problems and solutions encountered in website optimization, which should arouse the attention of webmasters.
