要害词密度（keyworddensity）

要害词密度（Keyword Density）是指在文章、网页、博客等文本内容中，某个关键词出现的频率与总字数的比例。通常，要害词密度应该控制在2%-5%之间，这样能够有助于提升文章的排名和搜索引擎优化效果。但是过度强调要害词密度可能会导致文章读起来不自然、脱离实际，因此写作时要遵循正常的语言表达方式，不要过分堆砌要害词。

锚文本（AnchorText）

威海seo术语威海锚文字
1227

锚文本又称锚文本链接，是链接的一种方法，和超链接类似，超链接的代码是锚文本，把文章中的要害词做一个链接，指向别的网页，这种方法的链接就叫作锚文本。

搜索引擎成果页面（Searchengineresultspage，SERP）

　SearchEngineResuitsPage的缩写，意思是查找引擎成果页面，用户输入要害词后，点击查找按钮后，查找引擎回来显现的成果页面。　　SERP是为特定查找显现的列表或成果，SERP有时分界说为查找引擎成果的安排（placement），依据本系列的意图，我将其称为页面而不是安排，在SEO领域中，在SERP中取得杰出的表现就是全部。

要害词密度（keyworddensity）

要害词密度指在一篇文章中，关键词出现的频率与总词数的比例。它通常用于搜索引擎优化的分析中，可以判断一篇文章是否用关键词过多或者过少。在优化文章时，要害词密度需要保持在适当的范围内，不仅要考虑搜索引擎优化的需要，还要保证文章的可读性和质量。因此，要害词密度不应成为制约文章的因素，而应该与内容和流畅度相结合，达到最佳效果。
