Analysis of the four reasons why there is no snapshot on the website but is included on the inside page

The website snapshot has always been one of the factors for webmasters to judge whether a website is friendly to search. Once the website snapshot is lost, the consequences are that the homepage of the website is deleted or there is an error on the homepage, which leads to the failure of the search primer to capture the page. Of course, sometimes when the homepage has a problem, it does not mean that the internal page also has a problem. Just like the website of the author, the homepage snapshot is lost, But the inside pages are included normally, and the speed is good. So what is the reason why the website has no snapshot but the inner pages are still included? Today, the author will analyze the reasons for this situation.

1、 ROBOTS setting error

When the internal pages of the website are included normally, but there is no snapshot on the home page, the webmaster needs to check whether the ROBOTS file is set correctly. Also check whether there is code in the source code of the home page to block spider crawling. Generally speaking, if a new website is launched and the inside page is included but the home page cannot be included, the first step is to check the settings of the ROBOTS file in the website. You must ensure that the ROBOTS file does not block the home page from being crawled by spiders. Next, check the source code of the website's home page. Note that there are no NOFOLLOW characters in the head of the source code of the home page. If both are OK, this may be due to other reasons of the website. Therefore, the most basic way to analyze whether the homepage of the website has no snapshot but the inner page has included is to check the settings of the ROBOTS file.

2、 There is an error on the home page that cannot be crawled by spiders

If the homepage can be accessed, but cannot be included in the search quotation. Then it is necessary to check whether there are error codes on the home page. Generally speaking, the home page can be accessed without fatal errors, such as several DIV tags added to the home page or one tag missing from a line of code. In this case, access will not be affected, but spider crawling will be affected. Therefore, when there is no snapshot of the homepage of a website, but the content is still included, we need to check the source code of the homepage carefully. The usual way to check is to visit the website through different browsers, and open the display of friendly HTML errors in the browser - Tools - IE Options - Advanced bar, so that the browser will help you check whether there are errors in the page. If there are errors, the browser will pop up a small window. We need to modify according to the prompts.

3、 The website has been revised recently

If the website needs to be revised for some reason, it is natural to make some relevant settings. And if the website has been revised in the near future and there is no snapshot of the website, but the content has been included, it is naturally caused by the revision. Usually, when the website has to be revised, the webmaster needs to set some relevant factors of the website. For example, set 404 pages to guide the invalid links made due to revision, and reassemble the website weight to the home page through 301 redirection, so as to update the content of the home page in a timely manner. In a word, if the website has no snapshot due to revision, the biggest reason is that the revision is not thorough enough, maybe there are some settings that are not conducive to inclusion or no guiding measures for revision.

4、 Homepage optimization is excessive

The webmaster is doing SEO optimization for the website every day, and the optimization focuses on the home page. After all, most webmasters believe that the ranking of the home page is much more effective than the ranking of other pages. If there is no snapshot on the home page of the website and the content is still included, it may be caused by excessive optimization of the home page. At this time, the webmaster should carefully check the optimization trace of the home page and try to remove the trace. For example, the website once added H1 tag, STRONG tag, B tag and a series of characters deliberately added for optimization on the homepage in order to rank, then when the homepage snapshot disappeared, the webmaster should timely remove the elements deliberately added to increase the optimization effect. So as not to endanger the collection of the entire website.

The above points are the reasons why the author has included no snapshots on the website. In fact, most of the reasons for this situation come from one of the above four points. We often say that the website snapshot is the snapshot of the home page, so the snapshot of the home page is naturally related to the home page. When analyzing, we should also focus on analyzing the status of the home page to quickly find the root cause of the problem.
