最佳视频广告运营方式与谷歌SEO标题优化指南
谷歌官方确认：标题修改不影响搜索排名
Google's official confirmation: Title modifications don't affect search rankings
谷歌的John Mueller在Reddit上明确表示，虽然标题元素(H1,H2等)对SEO有轻微影响，但其重要性已大幅降低。谷歌更关注的是标题在网页结构中的语义作用，而非作为直接的排名因素。
Google's John Mueller clarified on Reddit that while heading elements (H1, H2, etc.) have minor SEO impact, their importance has significantly decreased. Google focuses more on the semantic role of headings in page structure rather than as direct ranking factors.
标题层级结构的正确使用
Proper use of heading hierarchy
1. 一个网页通常包含1个H1标题(代表页面主题)和多个H2标题(划分内容区块)
1. A webpage typically contains one H1 heading (representing the page topic) and multiple H2 headings (dividing content sections)
2. 谷歌并不强制要求第一个标题必须是H1，SEO可以控制谷歌对标题的解释
2. Google doesn't mandate the first heading to be H1, allowing SEOs to control how headings are interpreted
3. W3C标准定义了HTML标题元素的规范用途，但谷歌执行较为灵活
3. W3C standards define the intended use of HTML heading elements, but Google's implementation is more flexible
