To optimize the enterprise website, we must grasp these four key points

Grab period

Generally speaking, spiders do not climb on the line. Generally speaking, there is a period of time, about one week.

Of course, it is also possible that a website has not been captured since it went online. One possible important reason is that the domain name of the website was previously used and blocked by K, that is, it was blacklisted by Baidu and delayed during the inspection.

How to determine whether a domain name has been used before? We can search the domain name with Baidu and Haole to see if there is any old information. The reason for using good le to search is that the information of good le is * * * *, and its collection amount is * * * *, which is relatively comprehensive. If you find that you have used a domain name before, change it decisively.

In addition, there is also a failure cycle in the crawling cycle. It is possible that the domain name is new, submitted online, and spiders also crawl. But there are problems in the process of crawling. There may be two situations. One is that the server space provider shields spiders, and the other is that DNS has a problem, that is, the domain name resolution server. When we visit the website, we first resolve the IP address, and then find the server through the IP address. The problem is that when resolving websites, if the IP address cannot be resolved, it may be blocked by server space vendors, especially some small space vendors or unstable foreign space vendors, which may lead to this situation. So try to choose a stable home space.

How to judge whether the space provider has shielding problems? Two tips. One is to verify the Baidu webmaster platform after the website goes online. If it is blocked, there will be a message reminder; The other is crawl diagnosis, which is used to submit the path and test whether the crawl is correct and stable.

Inclusion period

After spiders crawl, there is a cycle that may not be included immediately. And when it is included, the first page will also be included. There is a sandbox concept. It says that a new website will have a check period. Sandbox period may result in some pages not being published immediately, and may also result in a longer inclusion period.

How to shorten sandbox cycle should pay attention to some skills

First, in the sandbox period, it is very important to know whether spiders will crawl the inside pages. It may be based on the analysis of website logs. If the search engine grabs the inner page but does not publish it, then our solution is to send the outer page link. We mean to send the inner page link.

　 Voting period

Voting period refers to improving the comprehensive score of the website. Voting periods are also periodic. The discovery period is one week. The higher the weight, the shorter the discovery period. The statistical period is one week, and the time cannot be shortened. The action period is uncertain, and the death period occurs. When the link fails, it will enter the death period.

Calculation period

Related to a concept, Search engine optimization The search engine will preprocess the keywords, arrange them first, and show them to the customer directly when the user searches, which is why Baidu searches for keywords in less than a second, saving a lot of time, instead of only searching the database when you search. This is the so-called inverted index. In reverse order, it is not bare handed.
