Yesterday, small blog appeared down the right signs, domain is not in the first place, in the third, ranking directly from the third page directly to the sixth page. How to see whether the site down the right, this article introduces the site to reduce the right to view the method, there are some worthwhile to learn.

However, I know that my blog is not the problem, and today again looked for information, and then looked at Baidu spider crawling log, and then found there are many 404 pages, suddenly understand why, 404 pages is very unfriendly to se one of the factors, Their blog in 11.1th before doing is Taobao guest site, Baidu's but it contains a lot of pages, then again came to my site crawling when found that this page does not exist, this time is not through the site link crawling, but through the data stored in the database crawling, data Baidu will crawl over and over again, observe there is no update, and the return of the code is also different This is the reason I found that 404 pages as far as possible do not exist, one, or do 301, two, or direct control of the robots are no longer visited, On the robots.txt, please refer to the feeling of Google Quality guide-robots How to write, this is why we have to prevent the death of the link on their own site, there are many situations are also caused by the site down the right reasons.

Also found in the observation Web log, there are spiders to visit, to understand the writing of the website log, this article detailed site administrator: Learn to analyze the site log, 404 pages as much as possible to screen out, so that spiders can not access this page, but do 404 of the page is a very high user experience a promotion, Optimize your own 404 pages to improve PV.

Remember to see a lot of posts on the Chinaz mentioned, check the site dead link, has not thought of the site after the revision, the previous link all became nonexistent page, this is also coagulation fly son own negligence, is also a lesson, hope to write it, is also as one of the experience.

I repeat the site revision, how to quickly restore weight bar, daily update article + sufficient and stable outside the chain of resources, in fact, coagulation fly son feel, blog better than the forum, at least in terms of stability will be much better. I recently registered a member on the Internet, in the beginning of the stage, can be signed link, but now the Web site program revision, can not take the signature, that is, directly sealed off my chain of these resources, these factors we need to take into account, with the forum to do a wide range of outside the chain, But do fine do strong outside the chain can consider the blog, at least in the blog, will not delete some of your modules. Stability in Baidu seems to affect the weight of one aspect, many of our friends in the process of exchanging links, I will say the end, "Do not drop the link oh", in fact, very tired of those who withdraw links, in fact, for the import of links, export links, Baidu will have certain observation, stability is kingly, Today you have this export link, tomorrow you have no, you this is not fooling others? As long as your station does not appear a big problem, generally, is not a link.
