SEO 是 Search Engine Optimization 的缩写，中文通常译为搜索引擎优化。它指的是让网站更容易被谷歌、必应以及各类 AI 助手抓取、理解并推荐的一整套工作，目标是获得不需要按点击付费的自然流量。

SEO优化关注的是自然搜索结果，而不是付费广告位。广告一停流量就消失，SEO 的效果则会持续累积，但需要数月才能显现。
技术SEO解决抓取、收录和加载速度问题；页面SEO让每个页面清晰地回应一个搜索意图，包括标题、H1、内部链接和结构化数据；站外SEO则涉及外链、品牌提及和可信度信号。
打开当前排名前五的结果。如果全部是覆盖极深的大型网站，这个词暂时不适合。如果有内容陈旧或答非所问的页面，就存在机会。新站应从更具体的长尾词入手。
AI 概览和对话式搜索只引用少数来源。想被引用，需要在问题式小标题下提供一段脱离上下文也能成立的简短回答，并包含具体的数字或名称，同时保证 Schema 结构化数据有效。
关键词堆砌、购买链接、批量生成低质量内容都违反谷歌的垃圾内容政策，如今会直接被算法压制，恢复成本远高于短期收益。
SEO 指搜索引擎优化，即通过技术、内容和外部信号的改进，让网站出现在谷歌、必应及 AI 搜索的自然结果中。
技术问题的修复可能几天内生效，新发布的内容通常需要三到六个月才能达到应有的排名。
竞价按点击付费、立刻见效、停投即停；SEO 见效慢，但流量不按点击计费且长期有效。
可以。围绕一个细分主题发布相互链接的十几个页面，比在宽泛的大词上竞争更容易获得排名。
