A good link to the evaluation criteria

A good http://www.aliyun.com/zixun/aggregation/8495.html "> links to the evaluation criteria:

1, Alexa ranking

Alexa ranking represents the flow, of course, someone said, many sites are ranked by cheating, 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 the ranking of how high the site exchange is appropriate, there is no clear standard, I think that the rankings of your own site is too low too much.

2, PR value

This 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 I think that should be at least 4 to be regarded as a quality link.

3. Popularity

The other site has a certain degree of visibility, or in the industry has a certain degree of influence.

4. Relevance

The subject matter of the website should be related to our website.

5. Snapshots of web pages

Each other's web snapshot time, preferably within three days.

6, included number

First, the search engine's collection number and its website actual content number, should not be too big.

Second, the other site in Baidu and Google's collection of the best not too big difference, this can refer to its similar sites in different search engines included in the proportion.

7, Update speed

The content of each other's site is best to update every day, only updated every day of the site, the search engine will pay attention, users will like, links also have value.
