We will often see a big God, in a forum propaganda, tell you is Baidu's core algorithm. Then you point in, hundred title party, tell you or third set, we despise such a person? Today this article can not say absolutely is the core of Baidu algorithm, but will definitely give you a different feeling. So, what is the core of SEO?

First, Baidu's core algorithm from the data accumulation

1, Baidu collected more data, its algorithm more accurate, like antivirus software, they will collect every virus, and then add the virus in its database, and then the virus as a feature and then compare. Baidu's algorithm is the same truth. They collect a variety of data from the industry, including included, reverse links, site structure, clicks, user performance in the process. That's what we all know, there are some things we don't know, and then they combine that into a feature library and then rank the sites.

2, this kind of characteristic storehouse we can be observed

Baidu's This feature library, we are able to return the results of Baidu in the first 20 of the regular period of observation, and know, so this needs our top 20 record to save, for a long time to observe, to observe their collection, site architecture, keyword layout, article update cycle, the speed of the growth of the chain, The growth rate of backlinks, and the frequency of each update of Baidu, can be analyzed by observation.

Second, Baidu has added the user's analysis

This morning, opened Baidu I searched the next, I optimized the key words into the first page of the 2nd place, some small happy, but recently I have been heard that Baidu's algorithm added to the people or the use of the computer analysis factors, I went to my colleagues on the computer search under, sure enough, ranked on the second page.

I often search their own keywords This is certain, and then certainly more than the real user, and then Baidu to this rule crawl to, and then I search this keyword, the ranking is in front. It's better for me to get into the website I often go to.

What if it's a user? Recently search a word, or search a word frequency is relatively high, then Baidu will also take the same ranking method? Through the above introduction, you see, Baidu first to pass a large number of data, and then extract some features, and then use this feature to rank.

Third, summary

Baidu first has to crawl a lot of data, and then extract features from these data, and then use this feature ranking, which is what I think the core algorithm. This algorithm can be understood by long-term observation of the top 20 results of its return. We all know what to do here.
