Recent snapshots of their own web site is not in reverse, at first did not know why so, after my analysis of the site of the same situation to analyze, the majority of the results are due to the following reasons.

(a) A large number of collection in the station

Site collection at the beginning, Baidu will allow you to include the normal, as well as update the snapshot, because Baidu's technology can not do, timely find that the content is plagiarism. So the first sentence is not cheating articles, and give new snapshots and included. When Baidu through a number of comparisons found that your content is a lot of plagiarism, then the search engine will not only reduce the amount of your collection, but also a snapshot of the phenomenon of regression.

Solution: Stop collecting behavior, adhere to the site for the original article update.

(b) Unreasonable outside chain construction

Stop the chain to the site, or a lot of junk outside the chain will cause snapshots backwards, to know that the chain is not only the results of the rankings, but also can guide spiders to crawl your site, when you suddenly stop doing outside the chain, or do a lot of junk outside the chain, will reduce Baidu spiders through the station outside the path to crawl to your site.

Solution: Outside the chain is the main component of optimization, can not be stopped, high-quality outside the chain of a site rankings with a new snapshot is very helpful, adhere to do high-quality outside the chain.

(iii) Frequent changes to the title of the website

This phenomenon generally occurs in the new station above, many people do not understand the optimization, that their title is not very good, frequent title. This will cause Baidu to your site's re evaluation, not only will let the snapshot backwards, but also will cause the site down right.

Solution: The website title should be positioned well before the I remember on the line should not modify the title, really very necessary to modify the time, can only modify a few parts, can not affect the whole, if it has been changed, then can only wait patiently, in a period of time Baidu will determine your changes for the user, If it is beneficial to the user, the snapshot will soon be restored.

(iv) long time in the station does not update

When the site has been in the same content, Baidu Spiders will not be in the crawl, it is impossible to give you a new snapshot. If you don't update it for a long time, the snapshot will automatically return to an interface that you last updated.

Solution: Stick to the original article update as the 1th, if you do not have anything to update the industry, you can choose to make appropriate adjustments in the station, fine-tuning refers to changes in a small amount of content, such as the change in the wheel map, product picture changes, and appropriate fine-tuning can help you update the snapshot, And you can increase the score.

(v) Space instability

This factor causes very common, if your space frequently not open or open speed is quite slow, will affect the Baidu spider to carry on the normal crawl. When spiders can not crawl many times, will produce distrust, shielding your site.

How to judge the stability of the space?

You can tell by IIS log that when Baiduspider access generates a large number of 500 or 503 of code, you know that space is stable.

Solution: This is no good method, only to change a better space to solve the problem.

Of course, Baidu snapshot of the back of the file is not necessarily caused by the above reasons, there are many factors, this point is just pointing out a few more common factors.
