SEO optimization website dead chain work full analysis

  In the daily operation and optimization of the website, it is inevitable that there will be a dead chain. These dead links not only damage the user experience of the visitor, but also affect the friendliness and trust of the search engine. Therefore, it is a must to discover and process the dead chain in time. Less work. However, for many friends who don't understand SEO optimization, what is the dead chain, what harm does it have, how is it formed, and how to deal with it? This article will give you a detailed analysis.

  First, the definition of the dead chain

  The dead chain mainly refers to the link that was normal and later failed. It is mainly divided into two forms: protocol dead chain and content dead chain.

  Protocol dead link: The TCP protocol status of the page / the HTTP protocol status clearly indicates the dead chain, such as the 404, 403, 503 status.

  Content Dead Chain: The server return status is normal, but the content has been changed to a non-existent, deleted or required information page that is not related to the original content.

  Second, the danger of the dead chain

  The appearance of the dead chain will seriously affect the effectiveness of the operation and optimization of the website. Therefore, we must regularly check the dead chain and deal with it in time, but what is the danger of the dead chain, many people have no clear understanding.

  1, user loss

  When the visitor clicks on the link in the webpage, he finds that the page cannot be opened or a blank page. It is easy to lose patience and destroy the original goodwill of the website and leave the website, which is a great loss for the website. .

  2, wasting resources

  Search engine spiders have limited access to each website every day. If there are a large number of dead chains in the website, it will inevitably waste the quota of spiders, causing waste of resources and affecting the crawling of other pages in the website.

  3, the ranking dropped

  A large number of dead chains in the website will inevitably affect the search engine's rating on the website. In addition, the user experience is not good. The search engine will think that the website quality is low, and will not give the website a higher ranking, but will also reduce the power.

  Third, the formation of the dead chain

  In the process of daily operation and optimization of the website, inadvertently, a dead chain may be formed. Let's take a look at the specific reasons for the formation of the dead chain.

  1. Website revision

  The URL change caused by the website revision is one of the important reasons for the dead chain. Due to the business update or the website needs to be upgraded, the operator will modify the website, which will generate a lot of dead links.

  2, the website database error

  For a fully static website, the security of the database is very important, because changes in one parameter in the database may cause the web page to fail to open, resulting in the emergence of a dead chain.

  3. The content of the website was deleted by mistake.

  In the process of operating the website, if a page is accidentally deleted by mistake, a corresponding dead chain will be generated, and in the case of large-scale occurrence of the website, the attention of the search engine will cause the website to be reduced or even K.

  4, the site was hacked

  When a website is hacked, it will cause a lot of problems. Therefore, operators must be vigilant, avoiding the deletion of webpage content, website data errors, etc. Of course, some small sites rarely have this concern.

  5, the website to replace the server or space

  The replacement of a server or space on a website can result in a change in the IP of the website, which is one of the reasons why the website has a dead chain.

  6, website directory modification

  The modification of the name of the website directory will inevitably lead to changes in the URL path of the web page, and the old URL link will become a dead chain.

  Fourth, the treatment of the dead chain

  Once a dead chain appears on the website, how can we handle it properly?

  1, the search engine webmaster platform submits the dead chain

  After using the dead chain tool to check the dead chain of the website, you can make the dead chain into a text or xml map, sort it out one by one and upload it in the root directory of the website, and then submit it to the search engine platform for processing.

  2, Robots file is forbidden

  If there are fewer robots files generated on the website, SEOer can prohibit the search engine to include and crawl the 404 page of the website in the robots file of the website. The robots file prohibits the search and retrieval of 404 pages or other url links in the website.

  3. Complaints about search engine snapshots

  Using the search engine snapshot complaint method, the website's dead chain is quickly processed by the search engine, reducing the accumulation of dead links in the website.

  4, make 404 page

  During the optimization process, we need to create a 404 page of the website. When the visitor clicks on the dead chain in the website, the status code will change to 404, telling the user that the requested page does not exist. Making a 404 page not only guides the user's access, avoids user churn, but also effectively guides the search engine spiders to crawl and crawl on the site.
