Hello everyone, I am, hehe, the first time here to write things, feel not too bashful ah, I am SEO beginners, read a few articles on the Internet, but also read two books, for SEO, there is no deep experience, but simply on I know a certain point to write, prawns do not laugh ah!

What I am going to say is: Web page check weight algorithm, that is, search engine is how to check the similarity of two pages? This should be more concerned about the issue, because it helps make your "false original" more like a "original"

First I tell you about the famous I-match algorithm.

When we compare the similarities of two things, we tend to compare the things that can be balanced to the nature of the thing, like a game, to remove a maximum and the lowest points, and then change the same as the total score ~ ~

The I-match algorithm is based on the basis that in the text block, special high-frequency words and special low-frequency words can not respond to the real content of this text, so before comparing, first in the text of high-frequency words and low-frequency words removed (note: Here High-frequency and low-frequency refers to the document frequency, not the keyword in your web page density!))

Let's take a look at an example:

Here are two pages of text:

1. The Chinese football team, led by Miro, was the first to qualify for the World Cup finals, Sina Sports broadcast.

2. Miro led the Chinese football team to the first time in the World Cup final stage, Sohu Sports broadcast. (Hey, look at these two sentences very familiar?)

Remove High-frequency in document (i): China, in, get, match, qualify, Sina, sports, broadcast remove Low-frequency: Miro is left if the words are: football team, LED, first, World Cup, final, stage document (ii) to remove high-frequency: China, Sohu, sports, broadcast off low-frequency: Miro, Kill into the left if the words are: LED, the football team, the first time, the World Cup, the final, stage see it? The rest, the two are exactly the same. This is the existence of similarity, in fact, this example is very early.

To sum up: Search engine to detect similarity, the main is to participle and frequency comparison!! Do not know whether everyone is clear? Oh, next time a classic algorithm: Shingle algorithm.

Here we go. I wish you all the "false original" more and more good! SEO study also heavy responsibilities Ah!
