网站降权和网站被k的区别

1、网站降权是部分关键词排名下降。

2、被K站点是近乎所有排名消失。

3、网站降权不会导致索引、收录被隐藏。

4、网站被K最严重的时候，网站收录都会消失。

5、网站降权恢复相对比较容易。

6、网站被K恢复很难，没有专业的技术，基本上无法恢复！

1：检查网站是否使用了H1标签，除博客外任何网站经历避免使用H1标签，如果网站被降权，则去掉H1标签。2：检查是否有不良友情链接，检查这些链接的页面链接都是什么地方、IP是什么，这个IP是否被处罚过，详情可看卢松松曾经写的“如何检查同IP下的网站是否安全”。3：检查网站是否使用过Alt，特别是LOGO上面是否使用了关键字的Alt标签，如果有则去掉。4：如果是新站刚刚收录，那么应该蛋定，这个时候很可
