Recently, I often see some stationmaster said in the Friendship link exchange when each other always asks: Snapshot N, the weight >n, in the heart can not help to make the confusion, these although may have the situation to reflect the website situation, but in certain special circumstances, these three items are useless.

Snapshot: A snapshot is the search engine internal search procedures for the data on the network to organize the process, the file data will be indexed to store the specific embodiment of Baidu snapshot. That is, Baidu to crawl a site when the snapshot set up, the purpose is to prevent the site can not open the time to visit the site through snapshots to understand the main idea of the site. A site snapshot of the update speed is also a disguised description of the search engine on the site's attention to degree.

But there are many things that affect snapshots:

1. Site Title changes: The site title is a search engine on the ranking of one of the important factors, webmasters are aware that can not easily change the title, the title changes after Baidu will react a long time, to the new ranking of the site, natural snapshots will stop updating.

2. Server changes: If the site because of moving to change a new server will also cause Baidu snapshot of the stop.

3. Site is down right: if your site because the quality of the article or cheat or spam site, will cause Baidu to your site down the right, which will affect the snapshot.

4. Baidu's own problem: Baidu a big update will undergo constant debugging, snapshots also appear in disorder, some snapshots continue to update, and some snapshots are stagnant, but also some snapshots can be back a few years ago.

The full name of PR:PR is that the PageRank is presented by Larry Page and is divided into 0-10 levels. PR useless reasons are as follows:

1.PR algorithm formula is proportional to the external link, your chain more your PR will be higher, but remember that the PR is Google, Google Baidu is not a home, PR high and can not represent your Baidu ranked the better.

2.PR is updated a few months, even if the PR really useful that data is not allowed to have no value.

3.PR hijacked, a website 301 to a PR high site, such as PR update, their PR and be 301 of the site's PR the same. Nature can also take this PR to cheat links.

Baidu Weight: Baidu weight? Baidu has never said that it has the right to weigh, although Baidu said it was prepared to make a similar tools, but not yet out, now the so-called Baidu weight, is generally a webmaster station or love to station their own based on a set of algorithms to calculate the weight of Baidu, but such a weight of Baidu will be a lot of people to use. Just said there is a person in the group sent a picture, just let us look at the analysis.

  

Website Construction Station 4 days, weight 6, why? Webmaster and Love Station weight calculation method is based on your keyword ranking and give you the weight, look at the figure

  

The face index is 20,000. Is this index real? Keep looking at the following figure:

  

This is a clear glance, are in the past few days brush.

As far as the letter snapshot PR and weight, it is better not to refer to it can be, can not take them completely as indicators less than a certain value, so you may miss a good link but changed back some worthless links.
