Three, the original
experience two, outside the chain should pay attention to quality rather than quantity. From this adjustment can be seen, the chain of garbage by heavy blow on the forum outside the chain also seems to drop right, the forum outside the chain effect is not comparable to the previous, the high quality of the chain is king, and the soft chain will be a very good development trend, first temporarily and regardless of the quality of soft this layer, the soft high originality this feature will be able to meet the requirements of the original search, and high quality of soft Wen to release some of the weights of the high site, so as to give the site a good ranking. Of course, the forum outside the chain although be right down, to bring the website ranking effect is limited, but as a guide to the way a spider crawling website, its role is still there, especially for the new station just on the line, the appropriate forum outside the chain can be a good guide to the site spider crawling, in favor of the amount collected the increase of a problem but this time to note is the extensive links, not all the forum outside the chain, especially from a website to link not too much, but to link to a different site. Finally, Links is an access to the high quality of the chain is an important method, and Links is the source of the chain a relatively stable on the way, if there is a high weight website and you can exchange your weight, believe that the station will also improve.
