I received a call from a travel website customer today. The content of the call was roughly like this: "His website was built in May 2008. During this period, Baidu and Google's inclusion was always good. However, from March to April this year, Baidu and Google's inclusion was always good." It was decreasing, and in May, I was directly K-listed by Baidu, so I was contacted through the website.”
After understanding the general situation (the website changed its space in February), I did a comprehensive inspection of the website, starting from the domain name, space, robots.txt (search engine robot protocol), title, keywords, description, page layout, keyword density , tag application, internal links, anchor chains, external links, content, etc., have been checked. Except for some line articles that have the same situation as other websites, no major problems have been found. I I’m also depressed. What could be the reason for the Baidu K station?
I had no choice but to ask the client for FTP, insert the diagnostic code from Google's Webmaster Center to analyze the website, put in the code and click Verify, but the prompt "The 404 page returned a 200 code" was returned. I was confused ~ the original problem Here's what it means!! What does such an error mean? As we all know, a website cannot avoid entering wrong addresses, abandoned links and wrong links. When encountering such a situation, the server will return a 404 code For search engine crawlers, the 404 code means that the page was not found. When the search engine crawler gets this feedback, it will give up crawling and including the page, while the 200 code tells the search engine to confirm that the page can be included.
In this way, as long as the crawler crawls to an inaccessible link, it will return a 200 code to allow the search engine to include the same 404 page. Then the crawler will think that the website has a large number of pages with repeated content. Copying pages with repeated content is not allowed by search engines. Reduce the weight and focus on K station. The problem is found and the customer is immediately notified to correct the correct settings of the 404 page. Method: Select the website in IIS >> Properties >> Custom Error >> 404 >> Edit Properties >> Message Type Select File (Be sure to select the file, otherwise the 200 code will be returned) >> Browse your 404 file >> Sure.
Website optimization is all about details, and 404 is one of them. This is an issue that is easily overlooked. At least I ignored this important detail. The default 404 page of IIS is a page with a very poor user experience. 99% of people will choose to close this default page when they see it. However, a beautiful and friendly 404 This page may be able to help you win back a customer.
This is an online tool to check whether the 404 page return code is normal. You need to enter the wrong link to test, such as: www.ynsem.cn/wrong link.
