In 3721.html ">2014 years, Baidu measures the value of a site to observe the overall rating of the site, that is, you do any optimization for the site will have an impact on the overall rating of the site, and with the Baidu Green Luo algorithm update, Outside the chain for our site optimization has not been obvious effect, so we can only pay more attention to exchange links to get the weight and keyword ranking. Link refers to our site homepage to add the other side of the site's keyword links, and the other side of the site's homepage to add our site's keyword links. There are also people who use the resource station to get a large number of single link links, the more difficult to get the link, its value is higher, and the most difficult to get the link is a single link, in fact, we for each other's site with links and maintain within a certain number, this situation is not to disperse the weight of our site, But I said it was kept within a certain amount, more than this number will disperse the weight of the site, this time we need to get the weight through a single link to enhance the keyword ranking, but links if do not do the same will lead to our site by the punishment of Baidu or even the right to drop, This requires us to understand the exchange of links of attention.

1, relevance

For links, if our site has a high correlation with the other's website, the value of this link will be increased, not only for our site to pass a higher weight is also more conducive to our website to increase the expansion of keywords, of course, I said the relevance does not represent two of the site's industry must be the same, But to have relevance. If you do the industry is relatively unpopular, not competitive on behalf of the exchange of links with the object, this time we can also choose to exchange links to other industries, although the friendship links in other industries can not pass too much weight for our site, but will also play a role.

2. Number of links

For small and medium-sized sites, the number of links is best kept in 20, and for the large site home links best not more than 30, links do too much will spread the weight of the site, If large sites want to link through the way to get more extended keyword ranking can also use the way of the link in the page, of course, we use the internal page to exchange the links of other people's home to reduce our links to the requirements of friendship.

3. Exchange Frequency

There are a lot of beginners only know that links to the site's weight promotion and the site's keyword ranking has a certain role, so every day to exchange a lot of friendship links, in fact, for links, if your site in Baidu already has a certain degree of credit can be appropriate to increase the exchange frequency of friendship links, If your site is a new station, recommend Friendship Link exchange not too frequent, it is best to keep two days for a friendship link status. Because links need to be stable, we exchanged a lot of friendship chain, will certainly have the other side of your site to remove the links or your cancellation of the other site links to the situation, which is very affecting the credibility of a new station, so, friendship link is the same, reduce the frequency of exchange, But we have to improve the quality of links and links to the stability of friendship.

4. Grey Industry

It can be said that the gray industry is a sensitive industry, we all know that if the gray industry on the site of our site outside the chain, it will be search engines to determine the chain of junk, on our site not only has no positive effect, but will have a negative impact. Friendship links are the same, but links in this situation will have more serious consequences, for example, the gray industry's home page to join our site links will not affect our site, and our homepage to join the gray industry site links, then your site will be search engine punishment, so, We are exchanging links, although we can not exchange the high relevance of the site, we must also observe the other side of the site is consistent with the search engine requirements.

5. Cheating website

Usually SEO is also divided into white hat seo and black hat seo, white hat seo is in line with the search engine optimization principle to optimize their website, while black Hat SEO is through the search engine loopholes so that their site quickly get weights and rankings, of course, this site is very high probability of punishment, so, We exchange links, we must pay attention to each other's web site cheating behavior, such as Black Hat seo commonly used by the station group system, a large number of sites to exchange links, or a large number of links to a site link to a website, so as to get a fast ranking, In fact, this situation will be the search engine to determine the cheating behavior, and a lot of beginners do not understand the nature of the station group, so it is very easy to be involved in the crowd, and for the station group class site, search engine punishment is a station group all the site will be punished, if you are involved in the station group, Then you become one of them, it is easy to be punished by Baidu.

6, Nofollow

In the link front plus nofollow This method is in the past few years a lot of webmaster more commonly used methods, its role is to tell the search engine does not crawl this link, of course, if the other side of the site home to your friendship link before adding a nofollow, your site will not be passed the weight of the effect , but since webmaster tools can detect whether the link has been added nofollow This function is very few people use this method. Similar methods also have the form of robots.txt shielding, there are some people in the robots.txt in the form of orders do not allow spiders to crawl links page, this way with the code before adding nofollow is the same nature.

7. Picture Link

For spiders, spiders will not read the contents of the picture, and will not crawl to the image of the link address, but there are many beginners do not understand this truth, that the exchange of links with each other when the link with the form of pictures can look more beautiful. If the other side of the site with the form of pictures to add your friendship link, then this link can only play the effect of drainage, and can not play the weight of the effect of transmission, and links in the drainage effect is very weak, very few users will click on the links to your page. So. We exchange links when we still need to exchange text connection, text form of the link to our keyword ranking also has great benefits.

8. Dynamic Link

Dynamic Link This form is also very rare, if you have been contacted SEO this industry for a few years, then you will certainly have heard of SEO this keyword in the first place a few years ago, in fact, SEO this index is very high keyword, personal site is difficult to get ranked, But suddenly have an independent website to get SEO this keyword First name does attract a lot of people's eyeball, after analysis, he found that the link of his friendship is the dynamic form, that is, the home page shows 30 links, after 5 seconds and changed a group of friendship links, observe its source code in a total of hundreds of links, In fact, his practice can be counted as a black Hat SEO style, of course, this practice will also be Baidu found, so, his site only maintained three days to be punished by Baidu, although now very little friendship to use this site optimization measures, but we have to pay attention to the exchange of links to observe.

Summary: Although links can help our website to get the weight and keyword rankings, but if the links do not good enough not only to help the role, and even will be punished by Baidu, so we are in exchange for friendship links must be in accordance with the exchange of links to pay attention to the matter to do.
