Today's SEO industry, is really a mixed bag, the reason is very simple, this seems to be a lack of rules of the industry, as long as it will be a few words, a few theories can also be revered as "master"! The purpose of writing this article is to see a few days ago an anchor text and plain text in contrast to the article, but also want to say their own a few words.
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). Let a paragraph of pure URL in, that also only increased the exposure of the Web page, and did not have the text related to the calculation of the possibility of the page, because there is no anchor text to describe, in this case, the search engine needs to calculate the relevance, but also only through the text surrounding the 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.
The reason is that the anchor text is more difficult than plain text, and the amount of pure text is very easy to accumulate, so it gives people a sense of pure text effect better?!
