seo优化应该注意那方面
一、门户网页
很多网页被单独设计来得到高的搜索排名，但是另一个方面它们对站点的访客没什么价值，这就是门户网页，搜索登陆页面不是门户网页。
二、关键词重叠
就是大家熟知的关键词加载，这种技术真正就是一种对合理内容的优化实践的滥用。在搜索登陆页面上使用关键词是好的，并且大家经常这么做，然而当你开始只是为了吸引搜索引擎增加它们，你的网页就会被标记了。在轮番出现的图形或文字中堆积与前后文无关的关键词，或者在或者标签里，是这种不道德技术的变体。</p> <p>三、隐藏文本</p> <p> HTML提供了很多机会来在蜘蛛程序面前放置文本而让访客看不到。用难以置信的小尺寸展示文本，或者使用和背景颜色一样的字体颜色都是老掉牙的作弊手法。新些的技术包括使用样式表在网页上写关键词再被图片或者其他页面成分覆盖。总之，任何时候你从浏览器上看网页上发现不了，然而通过HTML源代码就可以看见，这就是作弊。只有合法的HTML注释是例外，它会被浏览器和蜘蛛程序同时忽略。</p> <p>四、重复的标签</p> <p> 使用重复的标题标签或者其他的meta标签在过去被谣传可以推进排名。同样的样式表方法可以隐藏文本也可以在此之上覆盖文本，这样在屏幕上只显示一次而在HTML文件上列出很多次。</p> <p>五、重复的站点</p> <p> 如果你能够克隆站点为什么还要停在复制标签上呢？你用稍许不同的内容将站点复制在不同的域名之下，并且让每个这些站点彼此链接（来增加它们页面排名的要素）。可能你的站点可以在前10位的排名结果里占了半数以上的席位。</p> <p> 以上的动作对于你的网站很危险，但坏消息是所有这些技术有时侯确实奏效。然而大多数时候，作弊技术就像股票的窍门，当你听说时可能已经晚了，股票价格已经涨起来了，并且搜索引擎已经有了对策。</p> </div> </div> </div> </section> <section class="wrap-box"> <div class="g-tit"> <h2>相关文章</h2> </div> <ul
