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, since 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.
