Instance resolution Web site Why two home snapshots appear at the same time

Site snapshots of the problem has always been webmaster special headaches, if the snapshot update speed is not fast, that let oneself update the content of the passion, if the update too quickly and worry that this is last gasps, representing the site is about to be down right phenomenon, especially some of the day snapshot of the site, not a few will flee by K or down the fate of the right. For the snapshot of this factor, really let a lot of webmaster are particularly nerve-racking. The author of a small station, recently appeared a strange phenomenon, site website query included in the amount of content, incredibly found on the home page at the same time two caption description, snapshot time is not the same snapshot. The author of the past few months have not moved the source code of the home page, but also did not have a revision of the site, even a little bit of the changes are not, the reason, the author believes that this situation should be half of the search cited the problem of crawling, half of the site itself, Personally think the site's own home page URL path of the uniqueness is not determined, at the same time there is no screen to do away with the home page path, and with the web space has a dual-IP absolute impact, there is a point is to search for the grasping problem. The following author to talk about their own analysis of this situation three reasons.

First figure:

　　

First, search for the problem of grasping

Search for the task to deal with the crawl every day is hundreds of millions of, not to mention in 24 hours to crawl the entire Internet's large and small site, it is inevitable that there will not be some mistakes. So when the site snapshots appear with two content headings, the new and old degree of a different snapshot, I think this may be because the search to update the database, not the old page to delete caused. When the spider crawls the content of the Web site again, the new snapshot will naturally be returned, and the new snapshot must replace the one that was originally stored in the database, but sometimes due to the heavy workload of data processing, it is inevitable that there will be no errors. such as the author of the snapshot of the station personally think that the main search cited in the new snapshot covers the old snapshots of the problem is not handled well, and make the original to overwrite the old snapshot of the work did not do, directly to the new snapshot as a new stand-alone page, and the old snapshot is also valid in the database, when we use the site query, It will naturally return two snapshots.

Second, the first page has more than one URL path

　　

　　

　　

As we all know, there are two or two different paths in the home page of a website, but the target is the same page. The probability of multiple URL paths appearing on the home page is very high. General website of the home page default URL address is directly using the domain name to display, and the author's website is generated by the background static page, 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 with the author's station the same situation. This can be in the background of the home page in the default document in the default page to set up a good on it.

Third, the Web site space dual IP impact

　　

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 a good thing, and very easy because of dual IP to the site's negative impact.

A snapshot of the site is one of the most important factors in determining whether a site is friendly to a search relationship. Of course, there is a problem with the snapshot, we need to analyze the reasons, to see whether it is their own or search for the source, if it is a search for the problem is not the problem, and so the search is again updated when the problem will be solved, if it is its own reasons, then should be handled in good time, In order to search for a new update, let the site to the normal track.
