Because the site links to the site Search engine optimization importance of increasing, so most webmasters in the construction and optimization of the time will be the first to consider adding links, but with any other goods and services, links have parallel imports and fakes, which requires you to identify the quality of a site link. As long as the selection of High-quality Web site links to optimize the site to play a positive role.

1, website theme relevance

Google's link to the site of the relevance of the higher requirements, so high-quality links and your site is related to the theme of the site link.

Find the content related to your site, of course, the site is the best area. If not relevant to see the specific content, such as the movie category of link scope is not limited to the film field, but also can be extended to entertainment-related, beyond these areas to carefully consider the quality of links issues. If too many occurrences are unrelated to the subject, it is possible to make page noises that make the overall quality of the site fall.

2, to identify the site's PR true and false

Anything can be faked, including the PR of the website. To identify the true PR value of a station, in addition to viewing the PR of Google Bar, also need to verify the authenticity of PR and reliability.

Those who use cheat way to obtain PR usually only a page, usually PR higher site will have a large number of pages have similar PR value.

3, verify the stability of the PR

Even the true PR has instability and insecurity, if the PR route is not or the site has a great change (especially important link adjustment) PR will drop or lost.

First, we enter the domain name or link page that needs to be linked in Google, using site:www.adsenser.org and site: Adsenser.org to directly review whether the page is included, generally speaking, if not a blog site, at least included in more than 35600. The higher the PR, the number of this collection will rise. If found that he included very low, must look carefully. In addition, enter the domain name directly in Google, such as www.domin.com and or domin.com, you can see some non-text link, if the other party has a lot of junk information, such as blog comments, message book, rather than the normal official channel, this station directly give up.

Since the database center may be a problem with IP, you can't see the real one, then you can use this

He queried the different IP addresses, the different regions of the Google results, a total of 17, to provide us with the most favorable evidence. This work is more cumbersome, but for the health of the site, still need to do.

4. Test voting mechanism

In Google's algorithm, a site counts as a vote, but many sites and lost voting mechanisms. This can be understood, in Google, PageRank is one of the more important components, he and the hilltop algorithm and Google's current neural network algorithm combined into Google's final crawl, because of this, many people see the benefits, many people are trading. Google also recognized this, so began to delete some of the high PR site link, do not index the site chain out, such sites in the market is the most. Pay special attention to the possibility that he has lost the voting function.

The way to prevent: is in Google to see his link, input link:www.domin.com or link:domin.com, see the role of link whether there are ads or other, in general, if it is a formal exchange, the site is called frined link It's not called AD, or sponsors. If the discovery of a large number of ad, it is possible that he is a short time to buy the PR, and then quickly attack, to find us exchange, to obtain the true PR, this must be more attention.

In addition, it is necessary to check his chain out, that is out links, to see several of his site a few links to the address, and then in Google back to check, such as link:www.domin.com and link: Domin.com, if the site has lost the voting mechanism, in the reverse link, the site will not appear again. Of course, we need to consider the time factor, then we need to check a few more, the general maximum may be 2 No, more than 3 did not find, resolutely give up.

Here's a tool to find out how much he links to quantity and quality:

This page also lists the number and quality of links.

5. See the probability of link being indexed and the score we obtained in the end

This is also the last step, to determine the score we can get, that is, after this link, we can profit, how much?

Here's an analysis of how many of his linked pages are exported

Then open the page, if less can calculate how much of the chain out, if more, on the visual is true, the general standard is:

If a page although the PR is very high, but he chain out about 30-40 or more, if this time we exchange with him, there is no meaning, because such a score, Google basically ignore. Then we must master a principle, if exchange, must see the CHU Exchange Link page pr. The scoring standard here is to say that his standard links and promotion.

Here, to emphasize a situation, that is, the internal connection is particularly much, to note that if the link page has exceeded 100 links, Google is very likely to recognize the link to the page, of course, this value generally, the higher the PR, the value may also increase. The basic float is 120-160. So, we still need to look at each other's link page. One is the internal link, the other is external.
