Default Css样式对搜索引擎优化的影响

CSS对搜索引擎优化既存在有利的方面,也有不利方面,主要表现如下:
CSS运用有一些不利的方面。比如超链一旦被某一风格限定后,全站统一的风格显得没有突出的重心,对一些需 要个性化表现的链接受到限制。另外一个问题是CSS被过度滥用的情况,如一些人用css来隐藏文本或滥用h eader标签,这些行为堪称搜索引擎作弊。还有一些人利用css让html内容率先出现核心内容,以为有 助于提升排名(实际上对排名没有帮助),这类CSS隐藏文本或利用CSS在html顶部堆积内容的做法可能 被搜索引擎视为作弊而遭到删除。
CSS大量运用于HTML和XHTML网页风格设计,用于制定字体风格、属性、控制内容的位置、轻松管理网页样式。div+css运用使得网页制作无需使用大 量的table表格定位,减少冗余代码,加快网页加载速度,是其极大的优势。
