When you do friends, do not be confused by its surface, must be in-depth understanding, or the old saying, better to do a high quality, do not do 10 garbage friends.

How to distinguish a website of good or bad, the following 8 points as long as you grasp, it can be said to be friends with the garbage said goodbye!

1. Snapshot has first. Look at a website good, must look at the snapshot, mainly Baidu snapshot, the method is in the Baidu search box to play site: Web site, the principle is snapshot closer the better, within 1 weeks first, in principle more than one months to be cautious. PS: Monthly Baidu will focus on updating the snapshot, so this is better than three days, look again. For more than 3 months, try not to have a friend chain, unless the following parameters perform well.

2.PR protection. This will be divided into two to see. One is the other side of the PR should be high, such as 8:7 good, 4:3 good. Another is the PR output value to be high (specific algorithm please Baidu). These two, PR output value First, try to choose more than 0.35, of course, the bigger the better. In fact, the PR value is the larger the better, the greater the more obvious your station is larger, but this significance is not like the PR output value so meaningful. It is recommended to choose more than 3, PR2 is also possible. Special attention is PR 0 must be cautious, careful is he was K, you and his friend chain, you are also K.

3. Friend chain Management. A good site will be a friend of their own chain of management, friend chain site as far as possible and their own site with the same industry, friends chain site PR value is relatively stable and so on. Here mainly look at two aspects, one is to see the friend chain has no PR for 0, and there is no return chain. You can query http://link.chinaz.com/Default.aspx on this page. Here need to remind is: some websites like to link to Baidu or bank, Alibaba, etc., these have back chain is understandable, if it is the general friend chain but no return chain, we must be cautious.

4. Key rankings. What is the ultimate purpose of optimization and friend chain? Keyword rankings. So the other side of the site's keyword rankings can also reflect the level of each other. Basically the normal site (as long as not the garbage station or be K or lax management) is basically not less than 70, if its station Baidu, Google rankings are relatively lean, then you are better cautious, especially Baidu. For domestic enterprises, Baidu accounted for more than 70% of the market. But Google rankings also reflect the level of the site to some extent. Or that sentence, Google is engaged in technology.

5. Included normal. What is included in the normal?? is not to say that must be included on the 100, or how much of the collection? The key is to make sure that the site is properly included. , because the site is less than the page, included reached 60%, this amount is acceptable. That has Serer will ask, how do I know the proportion of each other included? My judgment method is: the other side includes the page change amplitude is not very big, mainly is not a large K page is good. If you are using 51.la statistics, the other side is also using 51.la statistics, you can find the other included in the changes. For the inclusion of the situation, you can also see site: The site's snapshot date is how much, but this can only refer to the

6. Update order. This is also relatively easy to understand. The site is often updated, the frequency is basically stable. Surprise updates are not recommended.

7. Beautiful interface. The interface is beautiful, whether there have been text display problems, or typesetting problems. Too unattractive site is not friends of the chain, if it is a small problem, then to the other party, may be the other side is to modify the interface, but in the browser compatibility test ignored.

8. Static generation. The production of static page site first, the various effects of the CMS site is also very good. In fact, this also said a lot of SEO truth, you think I said right??
