I recently encountered a more headache, the site is a snapshot of the good, now incredibly there are two snapshots appear, one is the normal one is only the URL, summing up their own optimization experience, the pen to feel that there are a lot of cases, after all, snapshots appear two is not normal, so, the author these days have been looking for reasons , today I share with you, what is the cause of the site has two snapshots.

As pictured, this is the author of a small station, from the beginning of the 16th, there have been two snapshots, the author and many of the webmaster Exchange, consulting its solution, most of the webmaster said the default URL is not standard, there are 301 and 404 did not do well, I also tried in these aspects of the changes, overall, the effect is not bad. So what is the reason for this? In the author's summary, there are three main reasons:

First, the homepage default URL address setting is not standard

General website of the home page default URL address is directly using the domain name to display, and the author's website just started with http://domain name. org/ Index.html to do the home page default address, but for the search cited, with index.html and no, the two will be divided into different addresses, and search for the show, whether with index.html, will directly display the domain name, will naturally appear on the image shown in the way. So, under normal circumstances, the URL as far as possible to have uniqueness, otherwise the site will appear as the author of the same station. This can be in the background of the home page default document in the default home page set up on it.

Two, 404 Page setup is not standard

This is really deadly, and the author of the site two snapshots of the main reason is 404 page settings, because the author did not set 404 page before, but also because the space often suffered to attack, so that the author is always changing IP, so that the site has a snapshot, and now replaced the space, The natural 404 error turns to reset again, but the author in the settings are directly to the home page, so it will be easy to make the search lead mistakenly think you are deliberately to do optimization, and generally speaking, 404 page directly to the homepage of the search is not friendly, so, the author suggested that the webmaster in setting 404 pages, It is best to stay more than 5 seconds, so that users and spiders have a buffer time, and 404 the correct settings on the site snapshot has an absolute impact.

Third, the impact of dual IP

Site has two different IP at the same time to point to a site, then in the update of the site snapshot, the search will be led to the site into two snapshots, of course, it may be the space with two IP reasons, but how to distinguish the search cited how the IP is a site? Actually very simple, by analyzing the binding of the domain name to judge, As you use webmaster tools to query the site, will show the site is bound by the IP is which, and so, there will be an IP is not bound, but also the same site, so, search will give the binding domain name that IP display normal content, The IP that is not bound but can be accessed naturally directly displays the URL address. And this, is the author according to an old-timer's guidance to analyze, I think the double IP on the site snapshot is not good, and very easy because of dual IP to the site's negative impact.

Summed up the above several reasons for the two snapshots of the site, for a snapshot of their own site if this is the case, I suggest that we do not panic, after all, impatient is not solve the problem, the main analysis of their own web site are different, these places is the cause of duplication of snapshots, One by one analysis to find the reason, by finding the cause of nature can be quickly resolved.
