Although this kind of page has a lot of, but we webmaster often not much, let's talk about why to use these pages today, why use after can let our website to search engine friendly bonus points.

One: 301 permanent redirects.

301 Permanent redirect page is also called 301 turn or 301 jump, his role is to permanently transfer the domain name to another domain name up. Do not underestimate this simple function, in many cases played an irreplaceable role, such as: the site to change the domain name, page bulk Jump, more importantly 301 pages for the site's SEO aspects.

301 jump to tell the search engine, the URL has been migrated. At this time the search engine will crawl the new Web site, but also will be the old URL of the original link and the chain gradually transferred to the new URL, which means that the new domain name can get the weight of the old domain name, so that the impact of the domain name change to the minimum.

In practice, however, the situation is not as good as it seems theoretically. 301 function or relatively slow, Jiangxi SEO Bo main company set 301 jump Nearly half a year, but Baidu still will be the old domain name in front, the new domain name falls in the old domain name behind.

Two: 404 error pages.

When the user enters the wrong connection, the 404 error page is returned to the user, which is set to alert the user that the address does not exist.

For search engines, if the spider visited a URL but returned 404 wrong page, then the spider knew that the page is not there, it will no longer crawl this page, but also to the search Engine data center to submit the URL, so that the URL from the index to delete.

Three: 500 the server Internal Error prompt page.

Server, database error is always unpredictable, if these places out of the first failure, and just search engine spiders crawl to this return 400 of the page, that search engine will be how bad impression Ah! How can we solve the problem? 500 page is a good way.

500 page is a thatched cottage description of the page, it tells the search engine that the site now has a temporary small technical problems, perhaps a database error, perhaps the site maintenance.

So that spiders do not have to doors, nature will be friendly a lot.

So simple to say the theory of knowledge, as to how to achieve Baidu search, the answer is everywhere!
