SEO Audit - Meta Tags, Headings, Open Graph & Schema

Audit the on-page SEO of hundreds of pages in one run: title and meta description (with lengths), canonical, noindex, H1 and heading structure, Open Graph and Twitter cards, JSON-LD structured data, hreflang, images without alt, links and word count. Each page gets an A-F grade with the exact issues to fix.

• Plain-language issues. For example: "Title is 72 characters: it may be cut in search results (aim for 30-60)." or "The page is set to noindex: search engines will not list it."
• Catches the costly mistakes. Pages left in noindex (meta tag or X-Robots-Tag header), 404s, missing canonicals, invalid JSON-LD, pages not ready for mobile.
• Fast and cheap. One HTTP request per page, no browser: $2 per 1,000 pages, where full SEO crawlers charge $15 to $40.
• No result, no charge. Invalid inputs, unreachable pages and non-HTML files are returned for transparency but not billed.

What can I use it for?

• SEO agencies and freelancers: audit a client's key pages before a proposal, or check them every week on a schedule.
• Site migrations and releases: make sure no page went out with noindex, a wrong canonical or a missing title.
• Content teams: find titles and descriptions that are too long, too short or missing, at scale.
• Prospecting: grade the home pages of a list of companies and spot the ones that need SEO help.
• AI agents: let an agent check a page's SEO basics through the Apify MCP server (see below).

Tip: to audit a whole site, get its URLs with Sitemap URL Extractor and pass them here.

Input

{ "urls": ["https://apify.com", "example.com", "https://wordpress.org/plugins/"] }

Output

One row per page. Example from a real run (shortened):

{
    "url": "https://apify.com/",
    "finalUrl": "https://apify.com/",
    "status": 200,
    "responseTimeMs": 158,
    "score": 100,
    "grade": "A",
    "issues": [],
    "indexable": true,
    "title": "Apify: Marketplace of ready-to-run tools for AI",
    "titleLength": 47,
    "metaDescription": "Thousands of tools to automate your business. Get real-time web data, track competitors, generate leads, and integrate your apps and AI agents.",
    "metaDescriptionLength": 143,
    "canonical": "https://apify.com/",
    "canonicalIsSelf": true,
    "metaRobots": "index,follow",
    "lang": "en",
    "h1": ["85,842 tools for your AI"],
    "headings": { "h1": 1, "h2": 11, "h3": 20, "h4": 3, "h5": 0, "h6": 0 },
    "wordCount": 1596,
    "images": 78,
    "imagesWithoutAlt": 0,
    "internalLinks": 78,
    "externalLinks": 58,
    "openGraph": { "title": "Apify: Marketplace of ready-to-run tools for AI", "type": "website", "image": "https://apify.com/og-image?..." },
    "structuredDataTypes": ["Organization", "WebSite", "SoftwareApplication"],
    "error": null
}

The same check on example.com gives a C (61/100) with 7 issues: short title, no meta description, no H1, no canonical, no Open Graph, no structured data, thin content.

Grading: the score starts at 100 and loses points for each problem.

Problem	Points lost
HTTP error (4xx, 5xx)	40
noindex (meta or header)	30
No title	15
No meta description, no H1, no viewport, no HTTPS	10 each
No canonical, images without alt, invalid JSON-LD, slow server (> 3 s), title length off	5 each
Several H1, description length off, no lang, no Open Graph, no JSON-LD, thin content	3 each

The grade is A from 90 points, B from 75, C from 60 and D from 40.

Pricing

$0.002 per page audited ($2 per 1,000 pages) plus Apify's small run-start fee. No subscription. Invalid inputs, unreachable pages, non-HTML files and internal addresses are free.

How it works, and its limits

Each page is fetched once, like a search engine bot would (redirects followed, at most 4 requests per second per site). JavaScript is not executed: tags added by scripts after the page loads are not seen. Google renders JavaScript too, so for single-page apps compare with a browser-based check.

No personal data is collected: the output only describes the page's SEO elements.
