Free SEO Audit & Analyzer

An SEO audit is a systematic review of a website against the factors search engines use to rank pages: on-page signals (title, meta, headings), technical health (HTTPS, sitemap, robots.txt, structured data), content quality (word count, internal linking, alt text), and page experience (Core Web Vitals). An SEO checker or SEO analyzer typically looks at one URL at a time — a full SEO audit does the same across an entire site and consolidates the findings into a prioritized action plan. Our tool does both in one place.

Paid tools (Ahrefs, Semrush, Screaming Frog) go further on backlinks, keyword databases and desktop crawling at scale. This free SEO analyzer focuses on the on-page + technical + Core Web Vitals audit that fits most sites — real-user CrUX data, per-page drill-down, prioritized action plan, PDF export and a dashboard. Perfect for monthly reviews, migrations and client hand-offs without a subscription.

The Quick SEO Test analyzes up to 10 individual URLs you paste in — no sign-in needed, results in seconds, CSV export. The Full Site Audit signs you in, crawls up to 200 pages of a domain, runs site-wide probes (robots, sitemap, CDN, tech stack, PageSpeed Insights), generates a prioritized action plan and saves everything to your dashboard.

Core Web Vitals are the page-experience metrics Google uses in ranking: LCP (Largest Contentful Paint — loading speed), INP (Interaction to Next Paint — responsiveness), and CLS (Cumulative Layout Shift — visual stability). We pull them from Google CrUX (Chrome User Experience Report) — real data from actual visitors on your site over the past 28 days, not lab estimates.

Every issue gets an impact score (1–10, based on SEO severity) and an effort tag (Small / Medium / Large). Priority = impact × (0.5 + affected-pages share) ÷ effort. That means a small fix that hits 80% of your pages ranks above a large fix that hits one page. Rows are grouped so the same underlying problem (e.g. missing H1) surfaces once, not per page.

Yes. Before crawling, we fetch /robots.txt with realistic headers (many sites block the Python stdlib User-Agent) and honor Disallow directives. If robots.txt is missing or unparseable we default to allow-all, which is standard search-engine behavior.

Yes. In the Full Site Audit form, enter your site as the root URL and add the competitor URL in the optional "Competitor URL" field. We crawl both, then render a head-to-head comparison of scores, issue counts, sitemap size, CDN, domain rating and duplicate-signal metrics.

Up to 200 pages per audit — a good balance between coverage and time (typical audit finishes in 1–5 minutes). The crawler uses breadth-first search, canonicalizes URLs, skips assets and external domains, and stops when it hits the page limit.

Critical: hurts rankings or breaks user experience today (missing HTTPS, cloaking, 5xx errors on many pages, missing homepage title, poor Core Web Vitals). Warning: real problem to fix soon (missing H1, duplicate titles, long redirect chains, missing meta descriptions). Info: nice to have (missing OpenGraph image, no CDN, missing lang attribute on a few pages).

Yes. Every completed Full Site Audit is saved to your account under "Recent SEO audits" in your dashboard. You can revisit any past report, export it as a PDF, or re-run the audit at any time to compare. Only you can view your audits — reports are private to your account.

Monthly for active sites, quarterly for stable ones, and always right after a migration, redesign or major content push. The dashboard keeps history so you can see the trend.

Yes — the Quick Scan is free with no sign-in, and the Full Site Audit is free with a free Google sign-in (required so your audits can be saved to your dashboard and only you can see them).
