Shenyang website construction - how to solve Baidu crawl failure

Source: Shangpin China | Type: city news | Time: May 27, 2020
These two days, I received feedback from Baidu that website crawling is abnormal. This is very worrying. Obviously, Baidu webmaster platform can successfully capture diagnostic tools. Why did you catch the anomaly? I don't understand. Therefore, I went to the Internet to check the data of the morning, and the information I got summed up the common reasons for abnormal website keyword optimization and fetching, including the following:
　　 1. Abnormal server connection
There are two cases of abnormal server connection: one is that the site is unstable, and the Baiduspider is temporarily unable to connect when trying to connect to the server of your site; First, Baiduspider cannot connect to the server on your website.
The reason for abnormal server connection is usually that your website server is too large and overloaded. Your website may not work properly. Please check whether the web server (such as Apache and iis) of the website is installed and running normally, and use the browser to check whether the home page can be accessed normally. Your website and host may also block access to Baiduspider. You need to check the firewall of websites and hosts.
　　 2. Different network operators
Network operators are divided into China Telecom and China Unicom. Baiduspider cannot access your website through Telecom or Netcom. If this happens, you need to contact the network service operator, or purchase space for dual line service or cdn service.
　　 3. Domain name system exception
Domain name system exception occurs when Baiduspider cannot resolve the IP address of your website. Maybe your website has the wrong IP address, or the domain name service provider has banned the Baidu pider. Please use WHOIS or the host to check whether the IP address of your website is correct and resolvable. If it is incorrect or cannot be solved, please contact the domain name registrar to update your IP address.

　　 4. IP Block
The purpose of IP blocking is to restrict the outlet IP address of the network and prohibit users of this IP segment from accessing content, especially the Baidu piderIP. This setting is only required if your website does not want to be accessed by the Baiduspider. If you want the Baidu pider to visit your website, please check whether the Baidu pider IP is added incorrectly in the relevant settings. The space service provider where your website is located may also prohibit Baidu's intellectual property rights, and then you need to contact the service provider to change the settings.
　　 5. User agent is user agent
The server identifies the identity of the visitor through the user agent. When the website returns to an abnormal page (such as 403500) or jumps to another page for designated user access, it is user blocking. Only when your Website construction This setting is only required when you do not want to access the Baidu pider. If you want to let the Baiduspider visit your website, you have the settings related to user agents in the Baiduspider UA and modify them in a timely manner.
　　 6. Dead link
The page is invalid, and the page that cannot provide any valuable information to the user is a dead link, including two forms of protocol dead link and content dead link:
Protocol dead chain: dead chain explicitly indicated by the TCP protocol status/HTTP protocol status of the page, such as 404, 403, 503 status, etc.
Content deadlock: The return status of the server is normal, but the content has been changed to an information page unrelated to the original content, such as nonexistent, deleted, or requiring permission.
For dead links, we recommend that websites use protocol dead links and submit them to Baidu through Baidu webmaster platform - dead link tool, so that Baidu can find dead links faster and reduce the negative impact of dead links on users and search engines.
To sum up, we can probably understand the crawling principle of Baidu Spider, which ensures the traffic of the website, and the crawling of Baidu Spider ensures the inclusion. Therefore, only by meeting the crawling rules of Baidu Spider, can Shenyang website construction get better rankings and traffic.
