What this article shares with you is about the reasons for the abnormal spider crawling of search engines in website development. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

One of the most frequently used methods of website optimization ranking is to publish high-quality articles and let search engine spiders crawl to form Baidu snapshots to get a good ranking. If the search engine spider crawl is abnormal, it will affect the site optimization effect to a great extent.

Some web pages are of high quality and users can visit them normally, but search engine spiders cannot access and crawl normally, resulting in a lack of coverage of search results, which is a loss to both search engines and sites. Baidu calls this situation "crawling exception". For sites where a large number of content cannot be crawled normally, Baidu search engine will think that the site has defects in user experience, and reduce the evaluation of the site, which will be negatively affected in crawling, indexing and sorting to a certain extent. finally, it affects the traffic the site gets from Baidu.

Server connection exception

There are two situations when the server connection is abnormal: one is that the site is unstable and the search engine spider is temporarily unable to connect to the server of your site when it tries to connect to your website; the other is that the search engine spider has been unable to connect to the server of your website.

The reason for abnormal server connection is usually that your website server is running too large and overloaded. It is also possible that your website is not working properly, please check that the web servers of the website (such as apache, iis) are installed and running properly, and use your browser to check that the main pages can be accessed properly. Your website and host may also block the access of search engine spiders, you need to check the firewall of the site and host.

Network operator exception

Network operators are divided into telecom and Unicom, and search engine spiders cannot access your website through Telecom or Netcom. If this happens, you need to contact the network service provider, or buy space with a two-line service or purchase a cdn service.

These are the reasons for the abnormal spider crawling of search engines in website development. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
