SEO Audit Tool: website SEO checker with a 0-100 score per page

Crawl any website and get a technical and on-page SEO audit of every page: a 0-100 SEO score, every issue ranked as error, warning or notice, and a concrete fix hint for each. Titles, meta descriptions, headings, canonicals, noindex, broken internal links, redirects, duplicate titles and descriptions, image alt text, structured data, Open Graph, mobile viewport, HTTPS and mixed content, XML sitemap coverage and orphan pages. Plus a site-wide report with the overall score and issue totals.

$2 per 1,000 pages audited. A 500-page site costs $1. No login, no API keys, no proxies.

What it checks (45 checks)

Area	Checks
Status & indexability	4xx / 5xx / unreachable pages, redirects (full chain), noindex in meta robots or X-Robots-Tag, canonical missing / multiple / pointing elsewhere, indexable flag with reason
Titles & descriptions	Missing, too long (>60 / >160 chars), too short (<30 / <70), multiple titles, duplicates across the site (with the other URLs)
Headings & content	Missing or multiple H1, H1 equal to title, skipped heading levels, word count, thin content (<250 words), text-to-HTML ratio
Links	Broken internal links (with anchor text), links to redirecting URLs, internal / external / nofollow link counts, inlinks and anchors pointing to each page, click depth
Sitemap & crawlability	robots.txt rules honoured, XML sitemaps (incl. sitemap indexes and .gz), indexable pages missing from the sitemap, sitemap URLs that don't return 200, orphan pages
Mobile, security, performance	Viewport tag, lang, charset, HTTPS, mixed content, server response time, HTML size
Rich results & social	JSON-LD and microdata types (Organization, Product, Article, BreadcrumbList...), invalid JSON-LD, Open Graph, Twitter/X card, favicon, hreflang
URLs	Length, uppercase, underscores, query parameters

Every page gets score, errors, warnings, notices and an issues list like:

{ "code": "title_too_long", "severity": "warning", "message": "Title longer than 60 characters", "fix": "Shorten the title so it is not truncated in search results." }

The SUMMARY record in the key-value store has the site score, status code totals, indexable pages, average response time and word count, robots.txt and sitemap details, and every issue type with the number of affected pages and example URLs, sorted by priority. Rows in the dataset are sorted worst page first.

FAQ

Is it polite to the website? Yes. It honours robots.txt, sends at most 4 parallel requests per host, retries 429/503 with backoff and identifies itself with a clear user agent.

Does it render JavaScript? No. It audits the HTML your server returns, which is what search engines see first. That makes it fast and cheap (hundreds of pages per minute).

How is the score calculated? Each page starts at 100: minus 10 per error, 4 per warning, 1 per notice. Pages that return errors score 0. The site score is the average.

Does it check external links? It counts them. To check every internal and external link for 404s, use our Broken Link Checker.

Core Web Vitals? This Actor reports server response time and HTML size. For a fast check of what technologies a site runs, see Website Tech Stack Detector.
