🚀

Core Web Vitals

Real Google field data from PageSpeed Insights and CrUX, split by mobile and desktop.

  • LCP, INP, CLS, FCP, and TTFB.
  • Good, needs-improvement, and poor user distribution.
  • URL-level data with origin fallback when needed.
📱

Lighthouse & mobile UX

Lab audits from PageSpeed for rendered pages and mobile usability.

  • Performance score, render-blocking resources, unused JS/CSS, and image opportunities.
  • Viewport, font size, tap targets, plugins, and content width.
  • Rendered-page SEO signals that show what Google can see after JavaScript.
🔍

On-page SEO

Checks the signals search engines read directly from the page HTML.

  • Title, meta description, charset, viewport, and canonical.
  • H1, heading hierarchy, word count, image alt text, and lazy images.
  • Open Graph, OG image, Twitter Card, favicon, theme color, and manifest.
🧩

Schema & rich results

Validates JSON-LD quality for search features and clean structured data.

  • JSON-LD presence, parsing, and detected schema.org types.
  • Required fields for Organization, WebSite, Product, Article, FAQ, and Breadcrumbs.
  • Duplicate or low-value structured data that can confuse search engines.
📊

Technical audit

Checks crawl access, response quality, security headers, and link health.

  • HTTP status, HTTPS, redirects, mixed content, and security headers.
  • robots.txt, llms.txt, XML sitemap, web manifest, and AMP discovery.
  • Indexation blockers from robots meta and X-Robots-Tag.
🔗

Links & crawl paths

Checks how users and bots move through the site from the audited page.

  • Internal link count, anchor quality, redirects, and noindex targets.
  • Broken internal links sampled from the page.
  • External links that open new tabs without safe rel attributes.

How SEO Analyzer works

Three steps to a complete website audit

1. Enter your domain

Just paste your URL. No registration, no credit card, no installation. Works for any public website.

2. We scan dozens of signals

The crawler checks Core Web Vitals, metadata, content structure, indexation, structured data, crawl files, security headers, redirects, and links.

3. Get an actionable report

Prioritized issues with clear fix instructions, ranked by impact on your Google rankings.

Why use a free SEO analyzer?

Search engine optimization is the highest-ROI marketing channel for most websites. A single technical issue — a slow LCP, a missing meta description, a broken canonical — can cost thousands of monthly visitors. Our SEO Analyzer surfaces these issues instantly, so you can fix what matters before competitors rank higher. Built on the same standards Google uses to evaluate your site: Lighthouse, PageSpeed Insights, and the Web Vitals initiative.
