TF-IDF SEO审计报告
TF-IDF代表文档频次逆文档频率，用于衡量页面上给定关键字的重要性。与关键词密度不同，它不仅仅看关键词在页面上的使用次数，而且分析了更多的页面，并尝试确定该关键字的重要性。
例如，在汽车维修中，“轮胎维修”这个词可能比“涡轮增压发动机维修”更重要——主要是因为每个汽车都有轮胎，只有少数汽车有涡轮发动机。因此，“轮胎维修”这个词在谈论汽车维修的更大范围的页面上使用。效率更高。
这正是WebSite Audit中的TF-IDF报告能够捕捉到的内容！
通过查看竞争对手的关键词使用统计数据，TF-IDF公式将向您展示：
- 哪些关键词对您的主题最重要和相关？
- 哪些关键词在您的页面上合法地使用（就像搜索引擎期望它们出现在Google的索引中使用的TF-IDF一样多）？
- 您的页面上哪些术语使用过多或过少？
为什么要使用TF-IDF报告？
- 查看页面优化情况
计算内容优化因素。还分析您的页面在目标关键词上的优化程度。
- 发现与主题相关的新关键词
发现您排名靠前的竞争对手正在使用的关键词和短语
- 发现您需要更多使用或减少的术语
找到使用较少或使用更多建议的单词和短语，以查看如何调整您的副本以提高相关性
- 根据报告进行更改
- 现在您知道要添加，使用更多或使用较少的术语，您已经准备好进行必要的更改。
