I am very puzzled, although I have a domain name to do a pan-resolution, and IIS bound an empty domain name, but such a domain name I really did not parse, did not promote, did not optimize, but why Baidu will be included in such a domain name? I thought about it and thought that the signature file I made at the A5 forum seemed to have such links, So open A5 Forum, find the signature file, see the result. As shown in figure:

　　

Because the A5 forum on the limit of the number of signatures, I have to put a lot of web site links such a place, so there is a Baidu included such a domain name, so from this phenomenon, you can get such a conclusion:

1, the role of the signature file is still some: before we almost give up the signature file, in fact, the role of the signature is still some, just according to the weight of the forum, the role of the size of the different.

2, do SEO must promote the absolute address: as shown above, if the use of absolute address, you can avoid such a phenomenon.
