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

undefinedImportant 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。”
