How this service works
On-page SEO audit of one URL: title and meta description with their lengths, canonical, meta robots, H1s and H2 count, images without alt text, lang and viewport, Open Graph and Twitter card tags, JSON-LD blocks, internal and external link counts and word count, plus a list of issues and a 0-100 score. Reads the server's HTML (no JavaScript), up to 1 MB. Use to check a page before publishing or to compare competitors.
Output
A JSON object containing: the final resolved URL and HTTP status, page title and its character length, meta description and its length, canonical URL, meta robots directives, an array of H1 texts, H2 count, total image count and count of images missing alt text, page language, viewport presence, Open Graph properties (title, description, image), Twitter card data, number of JSON-LD blocks, internal and external link counts, word count, an array of human-readable issue strings, and a 0-100 SEO score.
Example use cases
Pre-publish SEO check for blog post
“Before I publish this article, can you audit https://www.myblog.com/drafts/new-post and tell me the SEO score, whether my title and meta description lengths are OK, and list any issues I should fix?”
Competitor SEO comparison
“Can you analyze the on-page SEO of https://www.competitor.com/pricing — give me their title, meta description, H1s, internal/external link counts, and score so I can see how they compare to us?”
Check landing page structured data
“Please audit https://www.mystore.com/products/widget for SEO and specifically tell me if it has JSON-LD structured data blocks, Open Graph tags, a canonical tag, and any missing alt text on images.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/seo/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured, machine-readable on-page SEO breakdown of a single URL without running a full crawler or JavaScript engine. It is ideal for pre-publish checks, competitive audits, or automated SEO scoring pipelines where you need title/meta/heading/link/image data and an overall score in one call. Prefer alternatives if you need JavaScript-rendered content, site-wide crawling, or backlink/off-page data.
Side effects
- URL is not accessible or returns non-200 status (reflected in status field)
- Page exceeds 1 MB HTML limit and is truncated
- JavaScript-rendered content not visible (static HTML only)
- Redirect chains may alter the final URL
- Malformed or relative URL input returns an error
- Pages behind authentication or paywalls return limited data
