On anchor text and plain text outside chain anchor text hard to send pure text quantity

Personally, the anchor text is still the most important form of outer chain. This has to be talked about from the chain principle, when the spider crawls a page, carries on the page analysis, will take the SRC attribute in a label (the anchor Connection), and takes away the text (anchors the text), thus causes the program to statistically, the website topic carries on the statistics, thus obtains the page topic (with which word matches). To make a pure URL in the Web site, it also only increased the exposure of the Web page, and did not have the text-related nature of the calculation of the possibility, because there is no anchor text to describe, in this case to seo/seo.html "target=" "_blank" > Search engine needs to calculate the relevance, It can only be done by surrounding text with this plain text. (through the surrounding text calculation of relevance, this is to do picture optimization of the peer, is again familiar with), the same in the case of anchor outside the chain, nature will also be the anchor text surrounding the text to calculate.

Why are there some peers who think the text is better than the anchor chain? It may be out of a cognitive judgment. There are pictures on the real, two charts to compare.

　　

　　

The number of the chain in the first picture is 21,669, and the second picture is 1247 outside the chain.

And the first image of the outer chain is 100% of plain text, that is, no anchor text

The second picture of the outer chain is composed of about 65% anchor text, 35% for the plain text outside the chain.

The rankings are as follows (as a result of the first post, to prevent some responsible impact, so the information screen off)

　　

It is clear that the total number of the chain is less than the total number of chain in the front of many.

Then why does it appear that some peers mistakenly think that pure text is the best outside chain form of the chain.
