1. 首页关键词少的排名好，首页关键词多分散权重。

　　2. 量大出奇迹，做的网站越多，排名上首页概率越大。

　　3. 网站几百个产品，不可能都排名百度首页。

　　4. 新站上线一般半年出排名。

　　5. 3~5个新站，总有一个排名好点，排名差的只能等待。

　　6. 企业站文章更新频率：最多一周一篇。

　　7. 老域名排名比新的好些。

　　8. 外链越多，排名越好。

　　9. 大多少企业有百度排名，产品一样卖不掉。

　　.......

　　网站优化不是技术，是一种销售方法。驾驶证，教师证。。。没有网站优化证书。

　　是个人都能考取驾驶证，你有钱才能开上豪车，和你车技无关，和驾校教练无关。。。

　　不是你开豪车就变成有钱人，买不起豪车，租的起。

　　只要你付的起钱或者自己愿意干，没有优化不上去的网站，划算不划算，自己判断。
