Site snapshots have been the webmaster to determine whether the site is a good friend of the search, one of the factors, and the site once the result is a snapshot of the site is K or the home page is a mistake led to search can not crawl page, of course, sometimes the first page problems do not mean that the same problem, like the author's website, The snapshot of the home page is gone, but the inner pages are normally included and the speed is good. So there is no snapshot of the site and the page is still included in what is the reason? Today, the author analyzes the reasons for this situation.

No snapshot of the site, the page is still included in the effect of the map

One, the robots set error

When the site inside the page is normally included, and the home without a snapshot, the webmaster first need to check their own robots file is set up correctly. Also want to see the source code in the first page of the screen Spiders crawl code. Generally speaking, if it is a new station on the line is included in the page and can not be included in the homepage, the first step is to check the Web site in the settings of the robots, you must ensure that there is no screen in the file is not blocked spider spiders Crawl, and then check the source code of the home page, need to The head has a character that does not appear nofollow type. If these two are no problem, then this situation may be the other reasons for the site, so the analysis of the home page without a snapshot and the most basic method is to check the settings of the robots file.

Second, the homepage appears cannot let the spider crawl the error

If the home page can be accessed, but cannot be searched cited words. Then we have to check the home page for error code, in general, if the home page does not appear fatal errors can be accessed, such as the home page more than a few div tags or a line of code missing a label and so on, such as the case will not affect access, but will affect the spider crawling crawl home. So, when the site appears there is no snapshot of the home page, and the content is still included, we need to check the source code of the first page. The usual way to check is through different browsers to access the Web site, and in the browser-tool-ie option-high bar to open the display of friendly HTML error, so that the browser will help you check whether the page has errors, if there is a mistake, then the browser will play a small window windows. And we need to change according to the prompts.

Third, the site recently made a revision

For some reason to the website to be revised, it is natural to do some related settings. And if the site in the near future has been revised and there is no snapshot of the site, the content is included, the nature of a large reason is due to the revision of the resulting. Under normal circumstances, the site has to be revised, the webmaster needs to site some relevant factors to set. such as set 404 page guide Due to the replacement of the invalid link, through the 301 redirect the weight of the site back to the home page, timely update the content of the first page. In a word, if the site because of the revision and no snapshots, then the biggest reason is that the revision is not thorough enough, may be some of the remaining adverse to the set or is not a good revision of the guidance measures.

Four, home optimization over

Webmaster every day in the site to do SEO optimization, and the focus of optimization are concentrated in the home page. After all, most webmasters think the home page ranking is much more effective than the ranking of other pages. If there is no snapshot of the home page, and the content is still included, then it may be because of the home page optimization caused by excessive, this time the webmaster should check the first page of the optimization traces, as far as possible to clear the traces away. If the site has in order to rank and in the home page added a series of H1 tags, fervent tags, b tags, etc. in order to optimize and deliberately increase the character, then when the first snapshot of the home has not been, the webmaster should be in time to add the deliberately added to optimize the effect of the elements removed. So as not to affect the entire site included.

The above points are the author of the site did not have a snapshot of the reasons for the analysis. In fact, most of the reasons for this happen from the above four points, we often say that the snapshot of the site is the snapshot of the home page, then the snapshot of the home page is naturally related to the home page, and in the analysis, we should also focus on the analysis of the status of the home page, in order to quickly find the root causes of the right remedy.
