Free technical SEO audit. Measured, not guessed.

Enter a URL. RankForge crawls the rendered pages and reports every technical-SEO issue it can actually evidence — with the affected URLs and a ready patch where one exists. No account, no AI, no data kept.

No signup. Crawls 3 pages, measures everything, keeps nothing. Full crawl in the free app or the CLI.

What it measures

Eight categories, ~35 checks, all deterministic. Green in a RankForge report always means measured — a finding is never reported without evidence from the page.

Metadata
Missing or duplicate titles and descriptions, length, OpenGraph and Twitter cards.
Indexing
Canonicals, accidental noindex, html lang, redirect chains, near-duplicate pages.
Structure
H1s, skipped heading levels, thin pages, readability, title vs. content alignment.
Images
Missing alt text and dimensions, lazy-loading, real byte weights and legacy formats.
Structured data
Missing JSON-LD and schema.org blocks missing required properties.
Internal linking
Orphan pages, click depth, broken links (real HTTP status), semantic link gaps.
Performance
Server response time, render-blocking resources, oversized HTML, mixed content.
Framework
robots.txt and sitemap presence and conventions for Next.js, Nuxt, Astro, SvelteKit…

How it works

  1. 1
    Crawl

    It fetches your pages the way a search engine does — the rendered HTML, following internal links breadth-first.

  2. 2
    Measure

    A rule engine checks each page, builds the internal link graph, and probes images and links for their real weight and status.

  3. 3
    Report

    You get a score per category and an issue list ranked by impact, each with its evidence and the pages it affects.

The honest limits

The free audit crawls 3 pages so it stays instant and free for everyone. The full crawl (up to 24 pages), audit history and fixes grouped by file are in the free app; unlimited audits — including localhost — are one command away with the open-source CLI: npx rankforge-cli audit <url>.

It audits the technical layer your code controls. It can't see your backlinks, your search volumes or your rankings — no in-browser tool honestly can — and RankForge never promises ranking outcomes.

It only reads public pages, the same way any crawler does. Private and internal addresses are refused, and nothing you audit is stored.
