This article introduces the reasons why Baidu snapshot did not grab title and description tags and what is the solution. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

In fact, the author has also published an article entitled "analyzing the reasons for the error of search engine crawling description tags", which mainly states that the description should truthfully reflect the substance of the entire website page, rather than blindly overlaying keywords. But this solution is not universal for some websites. In addition, the NOODP tag mentioned at the end of the article means that we do not use the open classification directory search system, that is, the open classification directory search system is not suitable for this site.

Here the author first talks about some more NOODP tags. In fact, MSN first announced in 2006 that the NOODP tag was used to prompt search engines not to use the description information in the classification information DOMZ, and then Google and Yahoo also announced that they supported the NOODP tag. But what needs to be noted is: at present, we are not clear whether Baidu supports this tag, at least the author has not drawn a conclusion from any Baidu official documents.

When SEO practitioners are engaged in website optimization work, they will also encounter inaccurate grabbing of website titles or just URL. Here are some suggestions from the SEO consultant:

1. A common situation is that when a search engine spider grabs the title tag of a website, it temporarily stores the title content, and then the whole page crawls down according to a certain order, and the intelligent process of the search engine accelerates. Now you can analyze the user's access habits, access keywords and other data through a certain algorithm, if the analysis results deviate from the actual results. It's directly reflected in the snapshot.

It is important to note that it is not that your title is poorly written or your description is incoherent, but that there is something wrong with the relevance of the overall page and the actual situation. For example, the web page noise (irrelevant information) is too much, the search engine spider can not make a correct judgment, and feel that your title or description does not match the content of the page, it may be based on the important text information of the page to get feedback and summarize and extract the relevant information.

2. With regard to the NOODP tag, add meta name= "robots" content= "noodp" to the head tag, and it will be useful for search engines that support this tag. Meta name= "robots" content= "noodp,noydir" is restricted to all search engines, including Google, Yahoo and Bing, but as mentioned in the second paragraph, it is unknown whether Baidu search engine supports this tag.

3, about the website title crawling into a link, this situation feels a little different from the situation mentioned above. In the SEOVIP ranking analysis article, the author shared two pictures, one of which is about the type and number of keywords description text outside its website, which can also reflect on the views of some SEO predecessors: external link description text should be diversified, internal links had better be diversified. In fact, SEOVIP description text diversification is not necessarily, the proportion of a serious imbalance is obvious, but its website optimization ranking is not still leveraged? Therefore, many viewpoints can not stand up very well after the case study of different sites! Therefore, what the author wants to express is: if your external and internal links are not diversified, and the proportion is seriously out of balance, it is likely that the title is a URL, of course, this is not absolute, SEOVIP site is not good?

4. Of course, there are other cases, such as server poisoning, server instability, ROBOTS restrictions on spiders, etc., which will not be analyzed here. SEO technology analyzes a class of cases that appear to be relatively normal, and individual factors are not analyzed too much.

Finally, a few more words: in general, the title usually comes from the title tag of the web page, the home page summary will come more from meta description, and the ordinary content page is dynamically extracted according to the search keywords. In addition, it should be noted that the title (title) tag is the focus of SEO optimization, so it is recommended that you SEOer, the key columns, directories or the home page must be handwritten, and it is best to add noodp and noydir tags in head, so as to facilitate standardization and optimization.

Baidu snapshot did not capture title and description tags on the reasons and what is the solution to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
