标题层级分析工具

审查任意页面的H1-H6结构。标记出缺失的H1、多个H1以及被跳过的标题层级。

如何使用本工具

1
Paste the full URL of the public page you want to inspect, including the https:// prefix.
2
Click Analyze to fetch the page and parse its raw HTML.
3
Read the per-level counts (H1 through H6) and the indented heading outline to see the document structure.
4
Review the Issues panel for a missing H1, duplicate H1s, or skipped levels, then fix the source markup and re-run.

标题层级既影响无障碍访问（屏幕阅读器通过标题进行导航），也影响SEO（搜索引擎通过标题来理解内容结构）。最佳实践：每个页面恰好有一个H1、不跳过层级（不要从H2直接跳到H4），并使用描述性而非装饰性的标题。本工具会提取每一个标题并标记出结构性问题。

Auditing a marketing landing page before launch to confirm it has exactly one descriptive H1.
Checking a blog template that renders the post title and the site name both as H1, producing duplicate top-level headings.
Finding skipped levels (for example H2 jumping to H4) on documentation pages where developers chose heading tags for font size.
Verifying accessibility for screen-reader users who navigate by heading shortcuts and need an unbroken outline.
Spot-checking a competitor's page to see how they structure sections for SEO.
Confirming that a CMS or page builder did not strip or reorder headings after a content migration.

标题层级为什么重要？▼

屏幕阅读器用它来导航；搜索引擎用它来理解内容结构；用户则用它来快速浏览。

我可以使用多个H1吗？▼

HTML5允许这样做，但SEO最佳实践仍然建议只用一个。每个页面请只保留一个H1。
