| 补充内容 - 爬虫优先级较低 |
| 页面或区域的框架内容 - 非核心内容 |
| 机器可读日期 - 有助于新鲜度信号识别 |

</script>| Mistake | Why it's wrong | What to do instead |
|---|---|---|
| Multiple H1 tags | Signals ambiguous topic to crawlers; dilutes keyword focus | Exactly one H1 per page containing the primary keyword |
| Missing canonical | Creates duplicate content issues when URLs differ (www vs non-www, trailing slashes) | Add canonical to every page, always pointing to the preferred URL |
| Title tag over 60 chars | Google truncates it in search results, reducing CTR | Keep title under 60 chars; put important keywords first |
| Meta description over 160 chars | Truncated in SERPs; the extra text wastes space | Keep meta description under 155-160 chars |
| Generic alt text | "image.jpg" or "photo" provides zero signal | Describe the image subject and context specifically |
| "Click here" anchor text | Provides no keyword context to crawlers | Use descriptive anchor text: "view pricing plans", "read the SEO guide" |
| Missing OG image | Unfurled links show no preview - kills CTR on social | Every page needs a 1200x630px OG image |
| Missing image dimensions | Causes Cumulative Layout Shift, hurts CLS score | Always include |
| Heading tags for styling | Uses | Use CSS classes for visual sizing; use headings for document structure only |
| Identical meta descriptions | Duplicate descriptions across pages dilute uniqueness | Write unique, page-specific descriptions for every page |
| noindex on important pages | Accidentally blocking indexation of content pages | Audit robots meta tags and verify Search Console coverage |
| 错误做法 | 错误原因 | 正确做法 |
|---|---|---|
| 多个H1标签 | 向爬虫传递模糊的主题信号，分散关键词权重 | 每个页面仅保留一个包含主关键词的H1标签 |
| 缺失规范网址 | 当URL存在差异（www/非www、带/不带斜杠）时会引发重复内容问题 | 为每个页面添加规范网址，始终指向首选URL |
| 标题标签超过60字符 | 谷歌会在搜索结果中截断标题，降低点击率 | 标题长度控制在60字符以内，重要关键词前置 |
| 元描述超过160字符 | 在搜索结果中会被截断，多余文本浪费空间 | 元描述长度控制在155-160字符以内 |
| 通用替代文本 | "image.jpg"或"photo"无法传递任何有效信号 | 具体描述图片的主体和上下文 |
| 使用“点击这里”作为锚文本 | 无法为爬虫提供关键词上下文 | 使用描述性锚文本：如“查看定价方案”、“阅读SEO指南” |
| 缺失OG图片 | 链接展开时无预览图，严重降低社交平台点击率 | 每个页面都需要一张1200x630px的OG图片 |
| 缺失图片尺寸属性 | 导致累积布局偏移，影响CLS评分 | 始终包含 |
| 使用标题标签实现样式 | 仅因为“看起来合适”就使用 | 使用CSS类控制视觉样式；标题标签仅用于文档结构 |
| 元描述重复 | 页面间重复的描述会降低内容独特性 | 为每个页面编写专属的、符合页面内容的描述 |
| 重要页面设置noindex | 意外阻止内容页面被索引 | 审核robots元标签，并在Search Console中验证覆盖范围 |
