For a long time did not go to see their own Yichang site optimization of this site, and today suddenly site and domain for a moment, found a problem, site:+ domain name and domain:+ domain name appeared Baidu snapshot time is inconsistent, and the domain home page fell to the second place, I've heard from friends before, but I've never met them before. Here is a little humble opinion of the situation, the following directly above:

Yichang SEO home Baidu Snapshot time

Yichang SEO domain Home page Baidu snapshot time

Say the site and Domain 2 instructions, site is the senior internal command Baidu search, once the correct site command, Baidu Search program will call all the data stored in the site, through comparative analysis, discard the same page, take the station all the latest snapshot of the record page, So site snapshots after sites are always up to date and unique. Domain is what we said Baidu related domain, and my understanding of domain is: To see all included in the target keyword pages.

We are looking at the search engine's 2 sets of systems, one is the information management system another is the information index system, the information management system is responsible for crawls the website the URL address as well as analyzes the title, the description as well as returns the status code. The latter is mainly responsible for indexing the content of the site, including the site rankings. In general, these 2 systems operate independently of each other, because rankings and countries need to consider a variety of sensitive vocabulary, so that the time difference between the server update, this situation on the new station should be more obvious, spiders crawl frequency is not enough, the weight of the peso page less, and the new station instability, may occur. I want to say that you may know why we sometimes see our site+ domain name and keyword ranking time is inconsistent with the reason, in fact, domain and site inconsistencies, I think there is an inevitable relationship with the Baidu database. In my previous blog, I talked about how to look at the relevant domains in website optimization

We can catch a few messages from this phenomenon:

1. If site and domain snapshot synchronization so that your site in Baidu this piece has a certain weight, snapshot of the synchronization is almost a search engine a more important indicator.

2. If the site snapshot time is earlier than the domain time, this is usually the new station will appear in the situation, and the construction of a certain chain, collected the URL of the site but because the weight is not enough to cause index update speed slower than crawl speed and time difference.

3. No home page or home page back to the main performance there are several aspects of the site is a facelift, and then Baidu "sit" with the IP site received punishment.

Then appear such a situation, personal feel more reliable practice is to look at the site log, from 3 indicators to check, crawl time, crawl path, return status code, so it is easier to find some problems in our optimization process, if the inspection found that the site of the province's optimization there is no problem, Then observe the waiting for Baidu update, generally a week or so. If you have a unique view in this area, feel free to add qq:1256271624 to the discussion.
