Those years SEO tool query and Baidu Gap

At present, the SEO tool (take Stationmaster station provides for example) has become one of the indispensable tools of seor work, the use of SEO tools can be a simple analysis of the site rankings, snapshot changes, the latest collection and the number of reverse chain, and so a basic situation of a website, but it is only a tool, but not Baidu's own development tools , is some SEO enthusiasts own development, call Baidu data, this and Baidu actually produced the data is different, the following on the SEO survey for example, to explain, the purpose is to tell everyone SEO tools, but recommended that we only do the reference, do not do the final result.

first, Baidu flow forecast:

SEO Tools According to Baidu Index combined with your site rankings for traffic forecasts, this is a combination of their own statistical tools in the station to see, it is clearly not in line. According to Seor said, "SEO forum" this keyword ranked the top three (Baidu rankings, the following is said to refer to Baidu's ranking, no longer explain) the site is not yet the keyword total traffic ranking of 30%, then Baidu traffic is expected to say nothing more. On this basis, and Baidu traffic related is webmaster tools to evaluate Baidu weight is even more nonsense.

second, today included:

The author has encountered two questions about Baidu today:

1. Added today, the actual total is not increased:

Example 1: Website www.***.cn, with the SEO tool query today included 49,400, as shown:

Baidu Total Collection is 64,800 as shown:

　　

But this is included in the day before yesterday is such a son, not on the basis of yesterday plus today's collection.

Why, then?

Explanation There are two kinds: (1) Baidu recent ventilation, database, problems, after a period of time will be good

(2) Baidu today is a collection of Baidu Spider today to crawl the page, previously included in today's crawl also counted, and also will delete some old pages.

2. The number of today's collection does not conform to the actual number shown:

The website www.￥￥￥.com today contains 3 figure:

　　

Click the number "3", the normal situation will appear 3 of the results, but this is only two, the following figure:

　　

This problem I have not found the reason, some peer explanation is Baidu hidden, SEO tool call error or the home page included two times, you think?

third, this month included:

This problem is similar to the above, but it seems more outrageous, some. Or take www.￥￥￥.com as an example, this month included 65, as shown:

　　

Click the number 65 and the following situation appears:

　　

is 85 instead of 65, more tragic is the total collection of this site only 84, the following figure:

　　

What is this for? Besides, the hidden interpretation of the bar, can only say that SEO tools did not come and update or Baidu SEO tool call wrong. From the above several examples we can see SEO tools and Baidu actual some small gap, indirect explanation, SEO tools can only be used as an analysis of a reference tool, must not be the final result.
