Regarding the problem of two or more snapshots on a website, many seoers have encountered it. For this problem, whether you are a seo expert or a novice seo, you will encounter this problem. BelowBeijing seoLet's talk about the problem of two snapshots for one website. Speaking of website snapshots, then we must know what website snapshots are all about. In fact, a snapshot of a website is a photo taken by a spider for your website. If your website cannot be accessed, there is a snapshot in the search engine. You can click to visit your website. By saying this, we will understand the original intention of the snapshot.
So why do so many people value this snapshot?
Some stations have the snapshot date on the same day, some stations have the next day, and some stations have two weeks, updated one week. The snapshot updates quickly, which means that search engines value your website and take a photo of you every day. That means that your website has a high weight in search engines. This also shows that spiders will come to your station every day. (Note: The website snapshots that spiders come every day may not be updated every day) Therefore, many webmasters attach importance to snapshots.
Are snapshots related to rankings?
As I said earlier, a snapshot is a search engine taking a photo of your website, so there is no direct relationship between a snapshot and ranking. We also often observe that some websites rank well and are stable in Baidu, but snapshot updates are slow. This can also explain. But we can think about it again, if your website snapshots are updated every day, then search engines attach great importance to your website. Then your station may rank well. So snapshots and your website ranking are indirectly related. However, the ranking of websites with fast snapshot updates may not be ideal.
Since so many people value snapshots, how can you make snapshots of your website update quickly? Below, take this website http://blog.sina.com.cn/beijingseo1/and take a snapshot of Baidu as an example.
Before explaining the issue of increasing the frequency of website snapshots updates, let's first look at a question. Some people ask: Why are my website snapshots different? Why are the snapshots of the site website different from the snapshots of directly entering the website? The question is: Suppose I enter Beijing seo Hua Xiufa into the search engine and get a website snapshot that is different from the website snapshot that I enter http://blog.sina.com.cn/beijingseo1 into the search engine and get a website snapshot.
Through the above question, I make a bold guess here: There are at least two data tables in Baidu's database, which I will call a ranking table for the time being: a data table that ranks websites. One is called a collection table: it is a table stored in the website. Suppose the fields in the ranking table have the following fields:
URL: Store your URL.
Snapshots: Store your snapshot date.
Related domain: is to store your domain.
Ranking: It is the ranking of keywords on your website.
Suppose that the fields in the inclusion list have the following fields:
URL: Store your URL
Collection: Store your collection
Snapshots: Store your snapshot date
Why assume two tables like this? Because through my observation, I found that the snapshot of the website directly entered, the snapshot obtained by entering keywords, the snapshot of the domain website are consistent, and the snapshot of the site website is inconsistent with other things.
From the above table, we can find that there are two identical fields: the two fields: the URL and the snapshot. Why are there two identical fields?
First of all, it is easy to think that these two tables must have a relationship, so which field is unique in the database to make these two tables have a cascading relationship? We all know that the domain name of our website on the Internet is unique, so the field in this connection table is the website.
Secondly: Then why is the snapshot field the same field in both tables? Here we assume that Baidu has two spiders, one is a spider that queries external chains, and the other is a spider that queries included (assuming the corresponding ranking table). (Assuming corresponding entry list) Both spiders can update snapshots.
