Absrtact: Optimization of the most important work is the content and outside the chain, because the importance of the chain can not be ignored, Baidu algorithm adjusted, the pattern of the outside chain has changed, now the chain of more and more attention to quality, so now the webmaster is no longer a large number of outside the chain, too many outside
The most important work of optimization is the content and the outer chain, due to the importance of the chain can not be ignored, Baidu algorithm adjustment, the pattern of the outside chain has changed, now the chain of more and more attention to quality, so today's webmaster is no longer a large number of outside the chain, too many outside the chain can not be improved rankings, or bring negative effects. For the outside chain I sum up 10 rules, perhaps to the big reader to help.
Anchor text in code
Spider search content is found by code, in the code the more weight on the higher, so the anchor text in the code above easy to be included. Often the position we see in the page does not reflect the position in the code.
From the above figure can be seen, anchor text inside the code is very front, such more easily be Baidu spider crawling crawl.
Second, the chain than the chain more easily transfer weight
Links are outside the chain and the chain, generally speaking, the chain is easier to transfer weight, you send an article, add a link to a page, if it is issued in other sites will be better than the results of this site. This is very simple, for example, you have a total of 10 dollars, the left hand has six yuan, the right hand has four yuan. So when you give your left hand a dollar from your right hand, you are ten dollars in total. So if someone gives you a dollar, then you have 11 dollars in total, so your money will increase. Outside the chain also is this truth!
Third, the new domain name link than the old domain name high quality
Perhaps a domain name will output many links, the first output link effect may be better, and after several times the effect is general. So the new domain name for the first time output link than old domain name Old link effect is better.
Four, the weight of similar site outside the chain effect is good
Do outside the chain of the site weight close to the best, good for example, car racing, two of people neck in hand, so that there is a challenge, can be tired of this mutual improvement.
Five, Anchor text link effect is better
The content in the code to do the best anchor cable, and its bottom or the weight of the navigation bar transfer effect is not ideal, because these links and must be related to the content of the article, so the effect of soft links is much better than friendship links.
Six, text outside the chain better than the picture
Anchor text outside the chain can bring more useful value than the picture link. Because the text is more direct way, spiders can crawl directly, and most of the weight is added to the text link above. In contrast, the image as the media itself can not produce value, but only after adding the ALT attribute has a literal meaning, so there is some relevance.
Main station secondary page than small important page effect better
High quality outside the chain is best from the authoritative website, but the authoritative site will not be easy to go out of the chain, we want to visit these sites to find their inner pages, these sites can bring a lot of value, although some small sites can give you a link, but the value is not necessarily considerable.
Viii. NoScript Links
NoScript Explain the spider unrecognized media, although the page will not appear noscript content, but the code is there, there may be some webmaster will do invisible links here, but now there is no need to create links here.
Ix. Short-term large number of external chain rankings to improve
Hair outside the chain is a long-term work, in the short run sometimes this phenomenon. Often there will be a site to publish an article is reproduced, if the site to give the original site links, the original site keyword ranking will be improved in the short term, so a large number of short-term outside the chain can lead to a high ranking.
Ten, the garbage outside the chain down right
Do not buy outside the chain, sell you outside the chain of the person will also sell the chain to other people, so these sites have too many outside the chain, your site will not get the corresponding weight, and if it is a spam site will also bring negative impact.
