We are doing SEO optimization, a lot of people do not pay attention to a more important factor is the importance of 404 pages, many people in the optimization of the site when the value of the chain and the content of the site is not wrong, but the 404 page settings are not good, the optimization of SEO impact is very large.

If the 404 page optimization is very good, the keyword on our site ranking is very good, can be very fast to upgrade our key keywords ranking, especially for many of the revised site is very important. We have this problem when we optimize our high blood pressure website, web site is just after the revision of the Web site in search engine crawling will have a process, and will not immediately convert to our existing Web pages, most of the pages or the old pages of the snapshot exists in the search engine database inside, Site plus domain name query included when you will find a large number of pages or old pages.

In the beginning of the revision of the time, but also the content of the site and outside the chain to do a regular optimization, but the ranking of the site has not been a good upgrade, after a period of time to query the collection of pages, found that a large number of pages included in the old page, the new page will not be included in a large number of immediately included, But after a period of time will slowly start to grasp the law.

Later observation of space access log, found that spiders crawl traces of access to a large number of or the old Web page, but also high weight of the spider's IP in the crawl, for the new content is the weight of the lower spider in the crawl. Later visited the site of the old page found 404 pages is the default without return links to the page, is simply the wrong text text. Later I changed the 404 page to bring back to the homepage of the link page, less than a week, the site's keywords have been a very big upgrade, very obvious.

In many of our people's understanding, the Web page deleted on behalf of the spider will not crawl, in fact, spiders are still crawling, search engines will have a period of time cached data. If we are not sure if our deleted pages will still be crawled, you can view the visit of our website log will find a lot of problems, not this problem, a lot of SEO optimization questions can be found in the log, and very specific, So we can according to the situation of the log to the site's SEO optimization has a certain purpose.

The above is I found in the optimization of the 404 error page A key role in the optimization of our SEO impact is very important, I hope to share with you.
