Home snapshot update lag or even stagnation is a very common phenomenon, although this will not affect the weight of the site, but it must indicate that your site in the structure of some problems, to solve such problems, we must find the reason from the site itself. If the site is included in the page, the full description of the spider can be normal access to your site, this is just confirmed that the snapshot of the home page does not update or lag is your own site problems.
1, old station homepage content update lag
Baidu Snapshot is the latest reflection of the website information, if the site's page snapshots are not updated, the most likely reason is that the page has not been updated, so that the snapshot is naturally lagging, so, if your site has updated pages, and the home page snapshot is not updated, the reason is that you do not have content to update the home page, Many small enterprises stand blindly in the pursuit of the layout of the site beautiful, really ignore the importance of Baidu spiders, the site does not have the content of the updated module, so that the site has been the same as ever, Baidu Spider See your homepage content has not changed, do not update your snapshot natural is also understandable.
2, the new station does not update
If it is the new station home update lag, it is a very normal phenomenon, now the internet in the garbage station a dime, so that the new station to force Baidu to spend more time, only when your site through the audit, your data will be normal display. Perhaps your daily collection is not normal to where to go, may be updated daily content, Baidu will only include a part, even if included may then be hidden, the only way to solve such problems is to adhere to the regular update and the right amount of the chain, of course, outside the chain do not have to chase the number of quantity, but should pay attention to quality.
3, the site has been revised
Site revision of the snapshot will also have a certain impact on the update, but the internal page will be included in the normal, the site's revision, not only updated, the phenomenon of snapshot regression is also likely to occur. This phenomenon does not worry, the recovery of snapshots is only a matter of time
4, the home page weight distribution is uneven
Any one site, will have the weight of the allocation, to distinguish the weight of the page level, and Baidu will be based on the size of this weight, give the snapshot time. The general site is the high weight of the home page, so the snapshot of the home page is generally updated faster, or even daily updates, while the internal pages of the snapshot will generally stagnate, wait until Baidu update, the internal page of the snapshot will be updated. So if the homepage of your website is not embodied in the core of the structure, are not as important as some of the internal pages, Baidu assigned to its weight will be less than some of the weight of the page, that is, Baidu will be your home page as an internal treatment, snapshots of the time naturally stagnant. If this is the cause, the general will have such a performance: the first page of the snapshot of the time and part of the internal page snapshot time, only when the Baidu update when the first page of the snapshot to update; We should be in the structure of the site so that the homepage to become the real core of the site, the home page should be pointed to the most pages, to make most of the Web site to have to jump to the homepage of the link. Baidu will be assigned to the top of the weight of the first page, the snapshot will be updated frequently. Reprint Zhen Tang: www.chinesesoup.cn
