# Free Website SEO Checker - On-Page Audit

> Paste a URL for an on-page SEO audit: title, meta, H1, canonical, Open Graph, robots, and sitemap in robots.txt. Host Domain Rating is included as a bonus - for a dedicated Ahrefs DR checker use the single-domain tool.

```yaml
url: "https://www.scrolllaunch.com/tools/seo-checker"
slug: seo-checker
category: onpage
keywords: "website seo checker, seo checker, on page seo checker, website checker, seo audit tool free, free seo audit"
```

## How to use

1. **Paste a URL** - Homepage or any public path you want to audit.
2. **Read the score and DR** - On-page readiness is separate from Ahrefs Domain Rating.
3. **Fix failing checks** - Use the title, meta, heading, and robots tools, then re-run.

## How to run a free website SEO check

A useful website checker answers whether the page is technically ready: title, meta, a single H1, canonical, Open Graph, and robots. That is this tool. For a dedicated Ahrefs DR checker, use the single-domain lookup.

The score is a checklist, not a Google ranking. Fix missing titles, multiple H1s, and noindex before you chase more links.

Compare two homepages with SEO Compare when you need a side-by-side matrix.

## What you get

- 0–100 on-page score
- Pass/fail checklist
- Live Ahrefs Domain Rating
- Works on any public URL
