How this service works
Check one public static HTML page for observed HTTP status, title/description/canonical conflicts, robots directives, headings, language, viewport and missing image alternatives. Return evidence-linked findings and practical corrections. Up to 1 MiB and five redirects; no rendering, ranking prediction, linked-page verification or actual index-coverage claim.
Output
Returns a JSON object with the page's HTTP status, title, description, canonical URL candidates, heading counts per level (H1–H6), image counts with missing alt tallies, robots directives, language, viewport presence, a list of evidence-linked SEO findings with suggested corrections, the timestamp of the observation, and a limitations disclaimer noting no JavaScript rendering, ranking prediction, or linked-page verification.
Example use cases
Pre-launch landing page audit
“Before we go live, can you run an SEO check on https://mystore.com/new-collection and tell me if there are any missing alt tags, heading problems, or canonical issues I should fix?”
Client site SEO spot-check
“I need a quick SEO report on https://clientblog.com/our-services — check for title and meta description conflicts, robots directives, and whether the headings are structured correctly.”
Monitoring a competitor's page metadata
“Can you inspect https://competitorsite.com/pricing and pull back what title, description, canonical tags, and robots directives they're using?”
Technical details
Endpoint
POSThttps://api.mekler.ai/v1/web/seo/check-page?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cost-effective per-page on-page SEO audit of a static public HTML URL without needing JavaScript rendering, site-wide analysis, or ranking data. It excels at surfacing metadata conflicts, heading structure issues, missing alt text, and robots directives in a single lightweight call. Prefer it over full crawl tools when you only need to audit one specific URL at a time for technical SEO signals.
Side effects
- URL exceeds 2048 characters — request rejected
- Page exceeds 1 MiB — content truncated or rejected
- More than five redirects encountered — fetch stops and error returned
- Page is blocked by robots.txt — directive noted, content not fetched
- URL is not publicly accessible or returns non-200 status — HTTP status surfaced but findings may be empty
- Invalid request_id format — request rejected with validation error
- Dynamic/JavaScript-rendered content not executed — findings reflect raw HTML only
