SEO notes (3) - Difficulat SEO websites

The websites that are difficult for SEO:
from http://www.dwseo.org/wangzhan-youhua/zhizhu-2.html


1) Orphan page: There is no child links;
2) Unfriendly SEO CMS: e.g: CMS that contains a lot of JS, frame and ajax.
3) Bad server Configuration: if 302重定向,访问权限,robots.txt设置以及服务器空间的稳定性, 都会阻碍Spider
4) Cloaking 比如隐藏文字、没有任何内外链的网页
5) Session Based Coding URL根据访问者的cookie随机变换、html代码中大量的字符,这些session闯下的祸,对于一个不依赖SEO的网站来说可能没什么,但是对于一个基于SEO的网页来说可是致命的。
6) no error handling意思是没有处理错误页面;如404跳转等

Others:
1) dynamic framework
2) contains a lots of iframes
3) change frequently
4) has a lot of bad inbound links
5) Flash website
