The highest level of interest in the exchange of friendship links and do outside the chain of issues

Push a forum of the http://www.aliyun.com/zixun/aggregation/12340.html "> website Diagnostics section opened so far, has been free to diagnose nearly 1000 sites, and at the same time to promote the introduction of the plate, every day will produce a lot of problems." And I found that many of these problems are repeated, especially some basic problems, almost every day people ask. So Kun decided to put some very common, we are very concerned about the issue of sorting into articles, to facilitate everyone to learn. Today to say a concern about the highest issue, exchange links and do outside the chain of issues.

The purpose of exchanging links

1, enhance PR. This is the most fundamental purpose of exchanging links. If you know what the PR value is, please see the bottom of the noun explanation.

2, improve the ranking of keywords. This is also one of the purposes, its importance not to repeat, about keyword optimization techniques, see the author's previous article "Kun: How to improve the keyword ranking in search."

3, improve the weight of the site. This is very important, only your weight is high, search engines will pay attention to you.

4, improve visibility. This article is still more targeted, for some specific sites and specific circumstances, will achieve this effect. For example, an unknown new station, if you can with Sina, SOHU, YAHOO, NetEase, Tencent and other big portals all do link words, that certainly to its popularity and brand image is a great upgrade.

5, improve the flow. This one is almost negligible, but the reason is written, because a lot of new people have a misunderstanding, think for friendship link is to increase the flow, so here serious correction, Friendship link for the flow of the promotion help very small, if the link to bring the number of IP can affect your site traffic words, There is no need for this site to exist is very questionable. In fact, I just learned to build a website, but also think so: (

Second, what is the quality of the link

1, Alexa rankings. 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, Visibility. 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.

6. Snapshot of the Web page. Each other's web page sunshine time, preferably within every day.

7, 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.

8. 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.
