in my opinion, the anchor text do its purpose is to tell the user there is relevant information, can be extended reading. But many owners just for Shanghai Longfeng do anchor text, ignore the anchor text of the original intention.
(4), such as the common reference anchor text concept existed early in fact, but experts believe that Google will be the panda, noble baby to join algorithm.
(3) anchor text effect will slowly decrease, may be "common" or other factors beyond the reference.
for small sites (especially new station), the anchor text does not have what ranking function like, anchor text is the only index "and" help, just "possible".

we know that the anchor text is an essential part in Shanghai Longfeng work, appropriate to add anchor text keywords ", will make the page where the importance and orientation of" has improved, which affects the keyword ranking.
(2) and not every anchor text has the same effect.
(1) considered nobility baby anchor text too easy, so will use other ways to assess correlation.
Shanghai dragon Moz think: anchor text will be replaced by the common reference.
(5) finally we believe that the common reference anchor text, etc., is not the replacement of one problem, these evaluation methods will continue to exist, but the algorithm focuses on the noble baby pick out the artificial operation, and then reduce the importance of it, so the question in the "human" and "nature". Not what is the anchor text and common reference. The more natural the link will be more search engine like
The final conclusion is:
for example, if a and B are the articles about the A, a paper said: search engine optimization. "The A had talked about the content". Then the A will also have the effect of Shanghai dragon.
through the observation of many foreign websites and Shanghai Longfeng case, the search engine is to reduce the effect of the anchor text, for here is the nobility of the baby, I believe that in the near Shanghai love will also reduce the anchor text of the Shanghai dragon effect.
is simple: if A and B are quoted from C, even though they do not link references, then C will have the same effect in Shanghai dragon. But many people also believe that in the future will be the "noble baby weight" than "common reference anchor text".
