The closest period of time everyday the snapshot circumstance of the website, website already a few months Baidu from collect experienced 10 days now half month updates snapshot to arrive 24 hours to update again to a week, update a few pages to update several much pages to from, arrive 24 hours from 24 hours of a few pages the snapshot of 200 much pages, this paragraph of time understands eventually, to Baidu snapshot should update ability 24 hours to be have weight, baidu did not use PR value to measure the weight of a website like Gu Ge, what does that use, I feel to return is the time that snapshot updates, the jump overing that a website updates in 24 hours has weight more more, because do not think what giving just is Baidu weight really, cannot use PR to see, of course this is pure belong to an individual close a point.

最近一段时间每天网站的快照情况，网站已经几个月了百度从收录到现在经历了十天半个月更新一次快照到一个星期再到24小时更新，从一次更新几页到一次更新数多页，从24小时几页到24小时200多页的快照，这段时间终于明白，对百度来说快照要24小时更新才算是有权重，百度没有像谷歌一样用PR值来衡量一个网站的权重，那用什么呢，我觉得还是快照更新的时间，一个网站在24小时更新的越多就越有权重，因为实在想不出什么才是百度权重，不能用PR一下看出来，当然这纯属个人的关点。
