Do you need to submit a dead chain for pages that are not included in the site? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

1. If there is an error page, return to the 404 code first.

If some pages in the site no longer exist, it should be misset 404 from an operational point of view. If you delete the relevant information from the database without setting 404, the user will see a program error page, which is very bad for the user experience. Therefore, search engines do not like the so-called 404 setting, but webmaster friends must not dare to do so because they do not like it. If you encounter an error page, you must set 404.

2. Set 404, and the next thing to do is to submit the dead chain.

A page that sets the 404 code can still be crawled by the search engine, but the crawled content will have no value to the user, so submitting the dead chain is an important work that can not be ignored for the webmaster. If you have carefully looked at the dead chain submitted page, the content dead chain corresponds to the template submission, of course, this requires you to add a little code to the tags of the relevant page. If your dead chain does not belong to the category of content dead chain, you can choose other submission modes!

3. Does the search engine crawl abnormal? Submit it in file form.

Many sites in crawling exceptions, you can see a lot of 404 error codes, this is the so-called dead chain, the next thing you need to do is to download the error page identified by the webmaster platform to the file, and consider the naming problem yourself! Open the file to delete the (1) at the end of the link, and then, be sure to save the file to the root of the site. Then you can use the file form to submit the dead chain, simple!

4. If you find that the page has not been included, does that mean you don't have to submit a dead chain?

Just like the editor today, if the content of a page goes wrong and the technician deletes it without setting 404, what should we do?

The editor first checked the page and found that it had not been included by the search engine. At this time, the editor was secretly delighted, because he felt that he no longer had to submit the dead chain, but he really did not need to submit it. In order not to be affected by this error message, the editor specially searched the relevant information on the Internet and found that it could not be so simple.

If you want to ensure that this unincluded message is not found by the search engine, then you have to download the log file and carefully observe whether the spider has crawled the message. If there is a relevant record, even if it is not included now, it does not mean that it will not be released in the future. If you do not submit the dead chain at this time, it will have an impact on the website, so before you need to submit the dead chain. Webmasters must pay special attention to the analysis of site logs.

Hearing this, some beginners may ask, if the spider has not crawled this information, and the page has not been included, does it mean that there is no need to submit a dead chain? In fact, the editor is not particularly sure about this, but in order not to affect the weight of the site, the measure taken by the editor is to use robots files to prohibit spiders from crawling and crawling the page content, isn't it very smart?
