How this service works

Comprehensive SEO audit of a URL. Checks title, meta description, h1 structure, image alt tags, canonical, robots.txt, sitemap, Open Graph, schema.org, link ratio.

Returns a structured SEO audit report covering: page title presence and content, meta description, H1 tag structure, image alt tag coverage, canonical tag, robots.txt accessibility, sitemap presence, Open Graph metadata, schema.org markup, and internal/external link ratios.

Example use cases

Technical details

Endpoint

GEThttps://api.strale.io/x402/seo-audit?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a broad, multi-factor on-page SEO health check for a single URL in one call, covering technical SEO signals (robots.txt, canonical, sitemap), metadata quality (title, meta description, H1), social metadata (Open Graph), structured data (schema.org), accessibility signals (alt tags), and link profile — all in a single request rather than running separate specialized tools.

Side effects

URL is unreachable or returns a non-200 status — audit may fail or return partial results
URL is missing the required query parameter — returns a validation error
The target page blocks crawlers via robots.txt or headers — some checks may be incomplete
Malformed or non-HTTP URL provided — returns an input error

Input

  "url": "https://www.example.com"
