Analyze Core Web Vitals
Measure and optimize Core Web Vitals scores that directly impact your Google search rankings.
Quick answer: Use the SEO Analysis tool through ToolRouter to analyze core web vitals directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolCore Web Vitals — Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — are Google ranking factors. Pages with poor vitals get penalized in search results while fast pages get a ranking boost.
ToolRouter's check_vitals skill measures all three Core Web Vitals metrics and provides specific recommendations for improvement. This includes identifying the largest content element causing slow LCP, layout shifts causing high CLS, and JavaScript bottlenecks affecting INP.
Regular monitoring is critical because vitals can degrade as you add features, third-party scripts, or new content. Running vitals checks as part of your CI/CD or QA process catches regressions before they impact rankings.
How to analyze core web vitals with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude helps you understand Core Web Vitals by explaining each metric in the context of your specific page. After running the analysis, ask Claude to prioritize which issues to fix first based on their ranking impact, and get concrete code suggestions for improving LCP, CLS, and INP right in your terminal session.

How to analyze core web vitals with Claude
Once connected (see setup above), use the SEO Analysis tool:
- Ask Claude: "Check the Core Web Vitals for mysite.com using the SEO tool"
- Claude runs check_vitals and reports LCP, CLS, and INP scores with pass/fail status
- For failing metrics, ask: "What's causing the high LCP and how can I fix it?"
- Claude provides specific optimization recommendations based on the data
Example prompt for Claude
Try this with Claude using the SEO Analysis tool
Check Core Web Vitals for mysite.com/homepage. If any are failing, explain what's causing the issue and how to fix it.
Tips for Claude
- Run vitals checks on your top 5 landing pages — they matter most for SEO
- Ask Claude to compare vitals before and after code changes
- Claude can suggest specific code optimizations for framework-specific issues
ChatGPT breaks down Core Web Vitals into plain-language explanations that product managers and designers can act on. It contextualizes your LCP, CLS, and INP scores against industry benchmarks, explains what each metric means for real users, and generates a prioritized improvement plan you can share with your engineering team.

Copilot surfaces Core Web Vitals data right next to the code that affects them. When you see a poor LCP score, you can immediately refactor the component causing layout shifts or optimize image loading — all without leaving your editor. This direct connection between performance metrics and source code accelerates optimization cycles.
