Depth analysis of Love station and Chinaz Baidu Weight value calculation method

In recent years by some companies to introduce Third-party computing Baidu weight of the tool, causing the majority of webmaster attention, and as an exchange of links and measure the weight of a site one of the important indicators. So how does this weight value get it? Follow the hex tune together to understand the fundamentals of weight data acquisition.

1, the key word scan warehousing

Daily by scanning a large number of keywords in Baidu rankings and record every keyword in Baidu serp first few pages (if take the first three pages) of the results and data storage (table structure see figure below, the table structure simply shows that the actual application is not designed this way, but is much more complex than this, which includes the keyword index ( No index of words generally not to record, the keyword of each of the corresponding URLs, and so on, when users submit a Web site to query the weight of the site, the server received the query command, and in the database to retrieve, All the results of the query are sorted in descending order by the rank of all indexed keywords on the site. Because it is not the official Baidu tool, so some of the keywords are not logged to the database, so may not be able to query some of the keywords.

Data store Table:

　　

By observing, the above n value generally takes the number of the first 50 names.

2, Baidu IP number range calculation method:

When we search pregnant women's radiation-proof clothing site "Www.91ffs.net", the program will be on the table all the data to retrieve, and find each matching the URL and its corresponding keywords and its ranking position, and then query every word Baidu index, and a certain algorithm calculation, The estimated IP result of the word is obtained.

Calculation formula:

The estimated IP number of the website ΣIPB =σipb1 +σipb2 + ... +σipbn

= ROUND (Q1XP1XI1) + ROUND (q2xp2xi2) +...+ ROUND (qnxpnxin)

ΣIPBN represents the IP number of the nth keyword

QN represents a site corresponding to the keyword ranking I ranking

PN means that a keyword of a Web site is ranked by the flow index weighted value (typically less than 1 greater than 0) for the first name.

In the Baidu index that is the key word

Round representation rounding algorithm (rounded)

Note: The above formula only from the Baidu index angle analysis, actually may also have the Alexa value, the PR value and so on, estimates it and then assigns one weights to carry on the weighted operation.

3, Baidu weight value results obtained

A total estimated IP number is obtained by the above method, then the estimate of the IP 10-level division, corresponding to which level, determine the weight of the site, specific series according to its website (such as Love Station and Chinaz, etc.), on the Internet to compare the number of authorized IP and the corresponding relationship is as follows:

Estimated traffic 0-100 of the Baidu weight is 1 (indexed keywords ranked in the top 50)

Estimated traffic 100-500 between the weight of Baidu is 2,

The estimated flow of 500-1000 Baidu weight is 3,

The estimated flow of 1000-5000 Baidu weight is 4,

The estimated flow of 500.01 million Baidu weight is 5,

Estimated traffic 10,000-50,000 of the Baidu weight is 6,

Estimated traffic 50,000-200,000 of the Baidu weight is 7,

Estimated traffic 201 million is the weight of Baidu is 8,

Estimated flow is greater than 1 million of the weight is 9

and Love Station "comprehensive query" inside the display of the weight value and the corresponding relationship between the IP amount is sometimes not in the above range or the gap is very large, I think is the Love station system caching problem, do not believe you directly click into the Love Station "Baidu rankings" to see, is not refreshed?

Finally said: All of the Baidu unofficial weight calculation methods are only used for reference, and can not really explain the weight of your site, do not too tangled this weight, if the site rankings good enough, the weight value sooner or later will have!
