Engineering-First Analysis

1

Client-Side Rendering Detection

Most basic SEO tools fail to execute JavaScript, missing critical content. Our engine runs a full headless Chromium instance to capture the DOM exactly as Googlebot sees it.

2

Core Web Vitals & Performance

Lighthouse-powered insights to analyze Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and other critical performance bottlenecks directly affecting your rankings.

Actionable

No Vanity Metrics

We strip away the noise. You get a clean, developer-focused breakdown of structural flaws, missing meta tags, and indexing blockers without arbitrary 0-100 scores.

Built for Developers

Exportable reports, deep DOM element tracing, and detailed error logs designed to be handed straight to your engineering team for immediate fixes.

FAQ

What does client-side rendering (CSR) check do? +

We run a headless browser instance to capture your site's DOM after JavaScript execution, showing you what search engine spiders actually see compared to raw server-rendered HTML.

What are Core Web Vitals? +

Core Web Vitals are key speed and user experience metrics (LCP, CLS, INP) that Google uses as direct search engine ranking factors.

How often should I run an SEO checkup? +

We recommend auditing your production site after every major deployment or dependency update to catch regression issues early.
