The importance of the chain is self-evident, and every webmaster understands its importance. The way to get outside the chain of what is generally a forum post replies, use the blog and question and answer platform to leave links, write soft text, links, etc., but, the previous several ways to get the weight of the chain is not high, and easy to lose, write soft wen is not their own strengths, so, friendship links are more stable outside the chain to increase the way. Today, we will talk about the exchange of links to several points of attention:

1, the relevance of the website

The relevance of the Web site as a link to exchange the first factor, because from a relatively high correlation links to get the weight is relatively high, more valuable. Because now the search engine to determine the quality of a site is a standard is the same industry site vote. If you get links to other industry sites to vote, that can be achieved by cheating, so only from the same industry site links vote, can truly come from trust and admiration. Therefore, the content of the site to pass the weight of higher, more access to search engine trust.

2, the content quality of the website

If the content of a Web site is collected or pseudo original, then, for search engines, is a worthless spam site, what is worth submitting to the user? Therefore, the site should have its own original, fresh, high-quality articles, so as to give users useful information to get the search engine's favorite. Exchange friend chain before, must see the other side of the site is not what is different, can attract users, attract search engine value information, otherwise, such a site can not exchange friends chain.

3, the number of sites included

The first thing to clarify is that the number of the amount of the site has less and worse impact on quality. However, the site is included although not everything, but if included too low words or to explain the site has problems. At present, Small business site more authoritative collection standard is more than 30, of course, this number also depends on the type of site, but also to their own discretion, at least with his site size has a certain proportion. If it is because the content is repeated, the quality of the article does not include, that is not the search engine new trust, such a site can not exchange friends chain.

4, the site's snapshot time

Snapshots of the site if the update is timely, that is to say that search engine spiders often come to patronize, crawl the site is relatively high frequency, is the search engine like, such a site is the search engine trust. Generally such sites are updated timely, and there is quality, it also shows that the maintenance of the site is more careful and technical, the weight of the site will grow more quickly. So, the weight of this website quality export is very high.

5, Link output page

Each site is the highest weight of the home page, so we must be with the other side of the site's home exchange, never use their own home page to exchange the link, unless his weight is Sina so high. Also do not do the whole station link exchange, easily by the search engine that is cheating.

6, export the number of links

The number of export links is also a lot of links to the exchange of reference factors, it is obvious that the more export to get less. This is the "cake principle", a website output weight is so much, the more export links of course the less the more points. Generally a website more than 40 export links, the weight of the site is also not worth exchanging friends chain.

7, whether set nofollow

Some websites set up the nofollow, that is cannot obtain the weight, once discovers, must put him to blacklist, this is very wicked. Some of the jump settings are done, and can not exchange links.

8, the number of reverse chain

At present, Yahoo has closed the chain of inquiry tools, the number of external chain can not be directly queried. Now can use Baidu Domain command query related domain to judge the site's "Outside the chain" quantity, of course, this is only used for reference, can not be completely equal to the outside chain. Because Baidu related domain statistics are all contain the relevant domain name of the URL are included, so the analysis, to see its source is not from the high weight of the forum, from its source as the basis for judgment.

The exchange of friendship links, we can get a stable outside the chain. However, links also need to check every day, otherwise it will affect the weight of our site and keyword rankings. If our site has links to a site down the right, then the search engine will think that our site and he is similar to the site, and implicated in the right to fall. Therefore, once found that the friend chain has been down the right of the site, must be timely removal.

Finally, to explain that friendship links just to get a way outside the chain, SEO optimization is a small step. Conversely, your site to get a higher weight, a lot of webmaster will find the door to do friends chain exchange, you will be more easily access to high-quality friends chain. To get good weights and keyword rankings, but also need to do a good job in the station optimization, improve user experience, solve user problems, retain the old users, attract new users, is the ultimate goal of SEO.
