没有办法，自己试着换了个地图生成工具，谁知道换了没过一天内容页权重全降了，好多连载影片快照都变成了N天前的，地图那一样显示待定，不过地图里的内容不一样，以前生成的地图只有时间和地址，没有更新频率和优先级，后面用的在线生成工具有优先级和更新频率，不知道是不是因为后面的地图有优先级把内页默认的优先级别降低导致的降权还是什么其他原因，这里是站长们高手云集的地方，见多识广，我的地图现在一直都是显示待定状态，站是http：//www.dy3166.cn，首页权重没有变，就是内页权重没有了，希望高手们帮忙找下原因，申明，本人在此发帖绝非炒作，是确确实实碰到了这个棘手的问题，希望高手们能够帮忙解答下，谢谢了。
