Website SEO Audit: On-Page SEO Checker

Audit any website for on-page SEO problems in minutes. Enter a URL. The Actor crawls the site, scores every page from 0 to 100, and lists each issue by severity, so you know what to fix first.

What it checks on every page

• Title tag: missing, too short, or too long
• Meta description: missing, too short, or too long
• Headings: missing <h1> or multiple <h1>s
• Indexing: noindex robots meta and canonical tags
• Images: missing alt text, with sample image URLs
• Content: thin pages (word count)
• Mobile: viewport meta tag; lang attribute
• Social: Open Graph tags
• Structured data: the JSON-LD types found on the page
• Security and speed: HTTPS, server response time, HTML size
• Links: internal and external link counts

Site-wide: a SUMMARY record in the key-value store lists duplicate titles and duplicate meta descriptions across pages, plus the average score.

How to use it

1. Add one or more website URLs.
2. Set Max pages.
3. Click Start, then download the results as JSON, CSV, or Excel, or open the "Pages" table view.

Pricing

You pay per page audited. There are no monthly fees, and the Max pages setting caps your cost.

Good crawling manners

• The crawler follows each site's robots.txt.
• It stays on the same site.
• It limits concurrency.
• It identifies itself with a clear user agent.
• It never logs in or bypasses access controls.

Only audit sites you own or have permission to analyze, and follow each site's terms.

Use cases

• Pre-launch and post-migration SEO checks
• Agency client audits and monthly reports
• Finding pages with missing alt text for accessibility work
• Spotting duplicate titles and descriptions across large sites
