SEO Audit Tool - On-Page SEO Checker for URL Lists

SEO Audit Tool audits a list of pages and returns one row per URL with 14 on-page SEO checks, each marked pass, warn or fail, plus an overall score (0-100) and grade (A-F). You are charged only for URLs that were fetched and audited; timeouts, DNS errors, blocked targets and non-HTML pages are free. The first 2 URLs of every run are free. Built with AI assistance (Claude); maintained by the publisher.

Quickstart (one API call)

curl -X POST "https://api.apify.com/v2/acts/pennydata~seo-audit-tool/run-sync-get-dataset-items?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls":[{"url":"https://apify.com"},{"url":"https://example.com"}]}'

Or open the Actor in the Console and click Start: the prefilled input runs as-is.

Checks

Check	Pass	Warn	Fail
title	30-60 characters	present, other length	missing
metaDescription	70-160 characters	present, other length	missing
h1	exactly one	more than one	none
canonical	link rel=canonical present	-	missing (warn)
imageAlt	90%+ images have alt text	60-89%	under 60%
robotsMeta	indexable	nofollow	noindex
https	final URL is HTTPS	-	not HTTPS
statusCode	2xx	3xx	4xx, 5xx
redirectChain	no redirect	one redirect	two or more
robotsTxt	/robots.txt found	missing	-
sitemap	sitemap listed in robots.txt or /sitemap.xml found	not found	-
wordCount	300+ words	100-299	under 100
openGraph	og:title, og:description, og:image	some	none
loadTime	up to 1.5 s	up to 3 s	over 3 s

Each check is an object { "status": "pass|warn|fail", "value": ..., "note": "..." }. Score = (pass x 1 + warn x 0.5) / 14. The details object holds the raw title, meta description, H1 texts, canonical, image counts, Open Graph tags, language, viewport, JSON-LD block count and word count.

Pricing

Pay per event, no subscription: $0.005 per URL audited ($5 per 1,000). The first 2 URLs of each run are free. Not charged: timeouts, DNS or connection errors, redirect loops, non-HTML responses, empty input and private/blocked targets. Set a maximum cost per run to cap spend; the Actor stops when the limit is reached.

Event	When it is charged	Price

FAQ

Does it render JavaScript? No. It audits the HTML the server returns, as a crawler first sees it. Pages that build their content in the browser can show a low word count or missing tags.

Is it a full-site crawler? No. It audits exactly the URLs you give it, one request for the page plus robots.txt and sitemap.xml once per URL.

Is the score Google's? No. It is a transparent checklist score from the table above, useful for comparing pages and tracking fixes.

Which sites can I check? Public http(s) pages only. Localhost, private addresses and non-http schemes are rejected, and every redirect hop is re-checked. No proxies, no captcha solving. Sites behind bot walls may answer 403 or 429 and are reported as such. The Actor identifies itself as SeoAuditToolBot. You are responsible for having the right to check the URLs you submit.
