A lot of webmaster friends, including some old birds are constantly studying the same problem, and what kind of Web site links is cost-effective. On this proposition, it is a benevolent and benevolent. A lot of SEO experts in A5 have repeatedly elaborated, summed up, in fact, is a few words, PR value to high, outside the chain to be more, snapshots to new, included more, correlation is better, export chain to be less and so on. These theories are all right, and after many years of SEO test, proved that these theories are correct, useful. But in practice, there are great drawbacks.

First of all, the PR update is too slow, some sites, although not high PR itself, but in Baidu's view, is a good site, its key words have a very good rankings, such as the author's mobile wallpaper station, although it is PR0, but ranked very good, and has been very stable, the main keyword Baidu ranked in the first page, in the GG is ranked in the top three, Estimated next PR update at least for pr4! and some sites, now looks PR pretty high, but the keyword ranking is very bad, such as the author of another site, a real PR4, in Baidu and GG rankings miserable, the next PR update will become PR0. If there is a brother superstitious PR, you can contact me, I am willing to sell at a low price.

Second, the number of outside the chain is too large, especially with a number of outside the chain, you can make a site in a short period of time to have thousands of garbage links, will fall in a few days, how these garbage outside the chain what to use, the number of reference value.

Third, the snapshot. Snapshots actually reflect the frequency of updates, if it is a business station or navigation station, the page is not often updated, the snapshot of course will not keep up, but this must not be said that its weight is low.

Four, included. As with snapshots, if it is a business station or navigation station, not often add new pages, included number is not high.

In the author's opinion, only the correlation and the export chain number is worth focusing on, the algorithm is now more and more attention to relevance, and in order to limit the selling chain, the number of export chain control is inevitable. But these two is not to judge a good outside the chain of key factors, because as long as the other side of the site weight high to a certain extent, relevance and export the number of chain, it is no longer important.

So, what is the best way to judge the outer chain? In fact, we can completely reverse thinking.

The quality of the chain in the final analysis is to improve the weight, and improve the weight is to improve the keyword ranking. Then, we are in the friendship link, simply do not judge the other party's PR and other relevant information, we first use some tools (at least what tools I do not say, online more is, lest there is a friend think I am in the AD) to judge the main words of the site in Baidu what position, ranking the more forward, on the words it has the weight. In other words, the more quality of the outer chain it exports. This is not more than the judge what PR, snapshots, more simple, more accurate. Especially when the link is very high related to the site, because the main keyword is similar, better to judge their friendship link is cost-effective.

Opinion, you are welcome to criticize the veteran birds. This article by the www.sjbzz.com webmaster feeds!
