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。

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。
