many webmaster friends all know, if a website for longer periods of time, then this site will have a natural weight, of course is the premise of this station is included in the search engine, we can understand this is the time effect of the site, and this is the time effect is, for example, the same two sites the modification of several title tags, we assume that one is a NetEase, is only a few months of the station, then, we all know the results is that the NetEase will be nothing, the search engine will be the first time the new index of NetEase ", and grab the other column page and the inside pages are modified, see title, if changed, will soon re crawl; and station are likely to be K.

webmaster friends all know, the influence factors of ranking score is the mutual influence, change a factor which leads to the change of other factors, the final form of the weight of the entire site, this is reflected, but the butterfly effect, Xiao Xiao believes that in the search engine started crawling a station when the site will give an initial weight and the initial weight is a constant, personally think that the initial weights may be the domain name categories and the site for the first time included time determined, included time is a constant weight, and the weights are given according to different categories such as domain name, domain name org given 3 of the weight, weight edu, domain name given 2 com, CN domain name given 1 weights and so on, so that the weight and the weight of the domain name included time accumulated became the initial weight of the site, Since then, the weight change site for changes in the initial weights on the basis of the.
