How this service works
On-page SEO audit of one public page from its HTML only: title and description length, one H1, canonical link, language, viewport, robots meta, Open Graph tags, images without alt text, internal and external links, word count. Returns each check with its value and pass or fail. No Core Web Vitals, backlinks or keyword volumes.
Output
Returns a structured list of on-page SEO checks, each with its observed value and a pass or fail result. Covers: page title length, meta description length, presence of a single H1, canonical link URL, language attribute, viewport meta tag, robots meta directives, Open Graph tags (og:title, og:description, og:image, etc.), count of images missing alt text, internal link count, external link count, and word count.
Example use cases
Pre-publish landing page SEO check
“Before I publish my new landing page at https://www.acme.com/products/launch, can you audit its on-page SEO — check the title and description length, whether there's a single H1, the canonical tag, Open Graph tags, and any images missing alt text?”
Blog post alt-text and link audit
“I want to make sure my blog post at https://www.myblog.com/2024/seo-guide is accessible and well-linked — can you check for images without alt text and list all the internal and external links on the page?”
Technical SEO health check for client site
“I'm doing a quick technical SEO review for a client — can you audit https://www.clientsite.com/ and tell me whether the viewport meta, robots meta, language attribute, and canonical link are all set correctly?”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/search/seo-audit-tool?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured on-page SEO check based purely on HTML content — covering the most common technical SEO factors (title, description, H1, canonical, Open Graph, alt text, links, word count). It is not suitable when you need Core Web Vitals, backlink data, keyword volume, or JavaScript-rendered content analysis.
Side effects
- URL is not publicly accessible (private or behind auth) — audit cannot retrieve HTML
- URL points to a non-HTML resource (PDF, image) — no SEO checks applicable
- Invalid or malformed URL supplied — returns error
- Page returns non-200 HTTP status (404, 500, etc.) — no content to audit
- Timeout fetching the page — partial or no results returned
