How to discriminate the value of a friend chain

With the spread of links in the network, search engines only for high-quality links to pay attention to the poor quality of friendship links to the site rankings do not work or even counterproductive. Links can not blindly pursue the "Han Xin soldiers, the more the better", as the saying goes: "The soldiers are not in the refined, will not be brave and in the pursuit of", but should be "quality does not demand", the exchange of links to focus on quality. Then we in the Friendship link exchange how to measure each other's friend chain whether has the high quality, below the Dugu fly to provide us some to judge each other friend chain's value reference index.

1. See the other site Alexa rankings

Alexa provides a comprehensive ranking, the number of visits rankings, page access rankings and other indicators of evaluation information, most people regard it as the current more authoritative site visits evaluation indicators. Alexa ranking represents the flow, Alexa rankings, although the accuracy of the data is inaccurate, but to a certain extent or can reflect the flow of a site and the popularity of the degree.

For general sites: Personal sites, corporate sites, online shop, Alexa rankings without any practical use. More people said that many of the rankings of the site is through cheating brush out, see this meaningless. There is a ranking of the site does not necessarily have traffic, but did not rank the site must not flow. As for I need to and ranking how high the site Exchange is more appropriate, in fact, this does not have a clear standard, Shanghai SEO Hsiao-dugu fly personally think as long as the other side of the site rankings do not compare your own site rankings are too low.

2. Check the PR value of each other's website

The PR value is part of the Google ranking algorithm (ranking formula) that identifies the level/importance of the page. Levels ranging from 0 to 10, and 10 to full marks. The higher the PR value means the more popular the Web page is. The weight of the site is not ranked, because the ranking is based on a single page, and the weight of the site is a whole consideration. Site weight determines the site rankings, this argument is too one-sided, ranking is a comprehensive algorithm factors, the weight of the site may account for part of it, does not represent all.

Relationship between weight and ranking of web sites

A. Weights are not equal to rankings
B. Weight has a very big impact on rankings
C. Increase the weight of the whole station in favor of the page ranking

PR value represents the weight of the site, only with the weight of the site exchange links, will enhance their weight. Generally speaking, as long as the other side of the PR value than their own higher can change. But Hsiao-Dugu fly personally think that should be at least 4 to be considered a quality link. For each other's station, even if the PR value is very high, but a lot of connections, such as more than 30, then add the significance is not big, the average to each station PR value is almost no, so the other side of the link less the better.

But since Google's withdrawal from China, Google's concern about Chinese websites has weakened, and the PR value has been updated every three months. There are many stations will appear in the PR value stagnation phenomenon, especially the new station, within 3 months no less than zero, so there have been a lot of webmaster has no longer value PR values. So the PR value we only as a reference indicator.

Also have to pay attention to is that we have to determine the other side of the PR value is true or false. Usually false PR refers to the use of PR hijacking technology to deceive the PR value of a means. We can identify it through the PR value detection tool of Love station.
