黑帽搜索引擎优化：黑帽搜索引擎优化是指一组通过违反搜索引擎服务条款的方式来提高网站或页面在搜索引擎中的排名的做法。 “黑帽”一词起源于西方电影，用来区分“坏人”和戴白帽子的“好人”(见白帽搜索引擎优化)。最近，它更常用于描述计算机黑客、病毒制造者以及对计算机进行不道德行为的人。
例如：内容自动化、门页、隐藏文本或链接、关键字填充、报告竞争对手(或负面 SEO)等。
白帽 SEO：白帽 SEO 是指在搜索引擎服务条款内的工作，以提高站点的搜索引擎结果页面 (SERP) 排名，同时保持您网站的完整性并保持在搜索引擎的服务条款范围内。
例如：提供高质量的内容和服务、快速的网站加载时间和移动友好性、使用描述性的、关键字丰富的元标记、使您的网站易于浏览等。
