Eight aspects to determine whether the exchange of friendship links is cost-effective

Friendship link is the most important one in the chain construction, generally each site has a special exchange of friends link staff, every day to Exchange 1, 2, to gradually stabilize the increase in the weight and ranking of the site, and even some sites dedicated to buy high prices to purchase some of the links to the site to quickly enhance the weight and ranking of the site, From this we can see the importance of friendship links. Because good links can enhance the site weight and ranking, you can enhance the site included, can increase the site traffic and reduce the rate of jump out of the site, you can say that the friendship link directly determines the development of the site. Since there are good, of course, there are bad, bad friendship links will drag the site snapshots of the hind legs, will make the site weight output imbalance, for short, or even lead to the site down right. So bad links can also bring devastating blows to the site. And the link is good or bad is how you choose to exchange the site, not the site itself, can be artificially controlled, I will talk about how to choose a friend chain:

1, look at the weight of the site, that is, PR

Now many people say that Google has been evacuated from China, exchange links when not too much value PR, in fact, I personally feel that the PR and Google evacuated China is not a relationship, this is only a measure of a site in the search engine important value, although now PR very long before the update, but also can roughly indicate the weight of the site, There won't be much deviation. Therefore, the exchange of links must still see the PR. and links to the import weight has a PR score calculation formula, a friend chain to get the weight value = (1-0.85) +0.85* (the site's PR value/export link number), Here 0.85 is a site's standard voting weights, from this formula can be seen, we exchange friend chain is to refer to the PR and export the number of links, the higher the PR, the greater the weight value obtained. Finally want to say that we can also refer to the "Love Station Net" in the "Baidu weight" to replace the PR calculation, personal feeling is quite accurate.

　2, see the number of exported links

As you can see from the formula just now, the number of outbound links to the site will also affect the weight of our gain, the number of less, we get the weight of the higher, the number of more, we will get less, when the number of more than a certain amount, we can get the weight of the value is negligible. This export link can also be calculated according to the formula, this is too long to use, I have forgotten, tragedy, there are people who know to write in the comments below. Generally speaking, according to the PR value, the number of export links is about 20-50.

3, look at the site snapshots, included

The date of the site snapshot will not directly affect the weight and ranking, look at the snapshot is because it can affect the site included, snapshots of how the new representative of the site spider to crawl the frequency of how high, spiders crawl more, the content of the site is easier to include. and spiders crawl friend chain site will also follow the link on its website to crawl to our site, the content of our site to crawl, to increase the content of the site included. Look at the inclusion is also the reason.

4. See the friendship link of the exchange website

Look at this, mainly to prevent the site is implicated, leading to the right to drop. There is a special word: sit, say is this aspect, if in your friendship link, have been Baidu or Google down the right, by K site, then you have a certain probability of the site will be identified as cheating or spam sites, and then together with the punishment.

　5, look at the code

Some people are cheap, specially adapted code to deceive friendship links, for example, a few months before the Wolf rain, do seo this word to the top of the biggest reason is that his site has more than 400 one-way links, he used the hidden links, nofollow tags, bridge page cheating methods to mislead us and his friend chain exchange, And don't let search engines see it. In fact, as long as the careful look at the code, basically can see the clue, such as nofollow tags, hidden links can be seen.

6, see whether the content collection

Baidu to the collection station identified as a garbage station, and refuse to do links, the consequences are very serious.

　7, look at the domain name

Look at the domain name is mainly to do a reference, if it is a new station, but the chain, the content is very high, indicating that the station has problems, the optimization method will certainly have problems.

8, look outside the chain

The chain is exploding or has been increasing dramatically, indicating that it may be mass. Too little is not good, indicating that the site is not to build outside the chain.

The last thing to say is that friendship links can not be done overnight, to long-term development. A day generally can only add 1, 2, delete links can only one of the deletion, add too much and delete too much will easily lead to fall right. and add good links to record, for example: QQ, Exchange time, PR, outside the chain, included, snapshots, etc., in case there is change, and usually every day to check a friendship link, once found to be down the right or to remove the link to our site to promptly dispose of, but also to a one, not too hasty.
