Example prompt: Can you run a full on-page SEO audit on https://myblog.com/best-running-shoes and tell me what's failing, what's passing, and what I need to fix to improve the score?

## When to prefer this

Use this endpoint when you need a structured, machine-readable on-page SEO audit of a specific URL with actionable fix recommendations and a numeric score. Prefer it over general web scraping when the goal is specifically SEO diagnostics — it covers a broad set of technical and on-page factors in one call for $0.005. It's ideal for agents building SEO reports, pre-launch checklists, or continuous monitoring workflows.

## Known failure modes

- URL is unreachable or returns non-200 — audit may reflect fetch errors rather than real SEO state
- Malformed or non-https URL input causes validation failure
- Page behind authentication returns limited or no content for analysis
- Dynamic JavaScript-rendered content may not be fully crawled
- robots.txt or sitemap.xml may time out independently, affecting those specific checks

## How this service works

On-page SEO audit of one URL: title and meta description length, canonical, robots meta and X-Robots-Tag, robots.txt allow for user-agent *, sitemap.xml with URL count, lang, hreflang, h1-h3 outline, word count, images without alt, internal/external links, Open Graph, Twitter card, JSON-LD schema.org types, favicon, viewport, mixed content; each check pass/warn/fail with a fix and a 0-100 score.

## Output

Returns a JSON object with the page URL, an overall 0-100 SEO score, a summary of pass/warn/fail counts, and an array of individual checks — each with an ID (e.g. title, meta_description, sitemap, hreflang), a status (pass/warn/fail), the detected value, and a recommended fix string when applicable.
