External links related to the site ranking this factor is very important, good and bad external links to the site rankings and weights are not the same, so here is a simple analysis of the rational use of external links.
One, external links can enhance the site's ranking this is no doubt, but the more external links the higher the ranking is not practical, external links pay attention to the quality of the relevant domain relatively close to the quality of external links than some unrelated external links high, such as I do beauty class site, Then the external links should be to some beauty network or beauty forums and other sites to send links.
Second, I found a lot of friends in the link, leaving the site inside the page link address, so as to enhance the weight of the page rankings, I do not deny that this can enhance the weight, but I personally think that the external link to the home page or table of contents pages more conducive to the weight of the pages in the In the release of external links when leaving the home page or table of contents pages can also enhance the weight of the page, the first page will assign the weight to the table of Contents page, the Table of Contents page will assign to the inside page, with such three layer structure to ascend the rank of the page inside the website, as long as the inside chain layout is reasonable will let your entire website traffic soar, So I suggest you try not to link a large number of external links to the page inside the site.
Third, many sites rely on the purchase of links to enhance the ranking, but recently some of the purchase of external links to the ranking of the sites in the decline, and did not buy external links just in some related fields near the site to send the ranking of the link has risen, this is why? Google released a message at the end of February this year is to some content station has carried on the large-scale punishment, each big search engine may already have the movement, because now the link trade market is too widespread, the serious influence search engine's impartiality, therefore we must have the attention.
