How this service works
On-page SEO audit API - crawl a single URL and return its on-page SEO health: overall score, title & meta description, H1, word count, internal/external link and image counts, load timing (LCP, TTI) and a list of detected issues (missing meta, broken status, not-https, images missing alt, slow load, …).
Output
Returns an overall SEO health score, extracted page elements (title, meta description, H1), word count, counts of internal links, external links, and images, core web vitals (LCP, TTI), and a structured list of detected issues such as missing meta tags, broken status codes, non-HTTPS, images without alt text, and slow load times.
Example use cases
Pre-publish blog post SEO check
“Before I publish this article, can you audit https://myblog.com/new-post and tell me if the title, meta description, and H1 are set correctly, and flag any SEO issues I should fix?”
Landing page optimization review
“I'm about to run ads to https://mystore.com/sale — can you check its on-page SEO score, word count, and whether all the images have alt text?”
Technical SEO issue detection
“Can you crawl https://company.com/about and tell me if there are any broken links, missing meta tags, non-HTTPS issues, or slow load time problems I need to address?”

Endpoint
POSThttps://seo.openverbs.com/v1/on-page?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, affordable on-page SEO health check for a single URL without running a full site crawl. It is ideal for pre-publish audits, landing page QA, or detecting specific technical SEO issues like missing meta tags, slow load times, or images lacking alt text. Prefer it over full Lighthouse audits when you need both content signals (title, H1, word count) and technical signals (LCP, TTI, HTTPS) in one call.
Side effects
- URL is unreachable or returns a non-200 status — issue flagged in results
- Page blocks crawlers (robots.txt or JS-only rendering) — may return incomplete data
- Invalid or malformed URL input — validation error returned
- Timeout on very slow pages — partial results or timeout error
- Non-HTTP URL scheme provided — rejected with validation error
