Audit Process

审计流程

Step 1: Gather Data

步骤1:收集数据

Use the available tools to collect information about the target site:
  1. Fetch the page using WebFetch to get the HTML content
  2. Check robots.txt at
    {domain}/robots.txt
  3. Check sitemap at
    {domain}/sitemap.xml
    (also check robots.txt for sitemap location)
  4. Fetch key pages - homepage, a few inner pages, blog post if available
  5. Check PageSpeed via
    https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url={URL}&strategy=mobile
    and
    &strategy=desktop
If the user provides a project codebase, also inspect:
  • Next.js
    next.config.js
    ,
    app/layout.tsx
    ,
    middleware.ts
  • Meta tag generation in page components
  • <head>
    contents, Open Graph tags
  • Sitemap generation logic
  • Robots.txt file
使用可用工具收集目标网站的相关信息:
  1. 抓取页面:通过WebFetch获取HTML内容
  2. 检查robots.txt:访问
    {domain}/robots.txt
  3. 检查站点地图:访问
    {domain}/sitemap.xml
    (同时查看robots.txt中的站点地图位置)
  4. 抓取关键页面:首页、若干内页、博客文章(若有)
  5. 检查页面速度:通过
    https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url={URL}&strategy=mobile
    &strategy=desktop
    获取PageSpeed数据
如果用户提供项目代码库,还需检查:
  • Next.js的
    next.config.js
    app/layout.tsx
    middleware.ts
    文件
  • 页面组件中的元标签生成逻辑
  • <head>
    内容、Open Graph标签
  • 站点地图生成逻辑
  • Robots.txt文件

Step 2: Audit Categories

步骤2:审计分类

Evaluate each category below. Score each 0-100 and list specific issues found.

评估以下每个分类,每个分类评分0-100分,并列出发现的具体问题。

Important Notes

重要说明

  • Always be specific. Instead of "improve page speed", say "compress hero image from 2.4MB to ~200KB using WebP format".
  • Include actual data points: real title tag lengths, actual PageSpeed scores, specific URLs with issues.
  • If you cannot access a resource (blocked by robots.txt, auth required), note it explicitly.
  • Compare findings against the site's top 3 competitors when possible.
  • For Next.js sites, provide code-level fix suggestions (e.g., specific component changes, next.config.js updates).
  • Never fabricate metrics. If you cannot measure something, say "Unable to measure - manual check recommended."
  • 务必具体。不要说“提升页面速度”,而要说“将首屏图片从2.4MB压缩至约200KB,使用WebP格式”。
  • 包含实际数据:真实的标题标签长度、实际PageSpeed得分、存在问题的具体URL。
  • 如果无法访问资源(被robots.txt屏蔽、需要权限),需明确注明。
  • 尽可能将发现与网站的Top3竞品进行对比。
  • 针对Next.js网站,提供代码层面的修复建议(例如,特定组件修改、next.config.js更新)。
  • 切勿编造指标。如果无法测量,说明“无法测量 - 建议手动检查。”
