SEO & Meta Tags Health Auditor

A fast, no-browser audit of the on-page SEO fundamentals that most directly affect how a page shows up in search results and social previews. Point it at one or more URLs and get back title/description checks, canonical and robots-meta status, heading structure, Open Graph/Twitter Card presence, and robots.txt/sitemap.xml discovery -- plus a letter grade, a 0-100 score, a severity tag, and a plain-English summary.

What you get, per URL

• A letter grade (A+ to F) and 0-100 score summarizing on-page SEO health at a glance
• A one-line executive summary ("Robots meta tag blocks indexing... this page won't appear in search results.")
• A severity tag -- critical (page returns an HTTP error, or a robots meta tag blocks indexing entirely), warning (other issues), or ok -- for instant triage
• Title and meta description presence and length, checked against configurable ideal ranges
• Canonical URL and robots meta tag (flagged if it blocks indexing)
• Heading structure: number of <h1> tags found (zero or multiple both flagged)
• Open Graph and Twitter Card tags, which control link previews on social platforms
• Viewport meta tag presence (mobile-friendliness signal)
• robots.txt and sitemap.xml discovery, checked once per unique domain and shared across every URL on that domain
• Pages are audited in parallel (configurable), so a batch of 50 URLs finishes in a fraction of the time a one-by-one audit would take

Why this instead of checking manually

	Manual spot-checks	SEO & Meta Tags Health Auditor
Coverage	Whatever page you remember to test	Every URL you list, automatically
Speed	View-source, scroll, repeat per page	Seconds, via parallel auditing
Triage	You read the raw HTML yourself	Pre-classified severity + letter grade
Repeatability	Forgotten until traffic drops	One click, or schedule it
Output	Notes in a doc	Structured dataset, exportable to CSV/JSON/BI tools

Who this is for

• SEO consultants and agencies running a quick health check across client pages
• Developers verifying meta tags are set correctly before or after a launch
• Content teams auditing a batch of blog posts or product pages
• Anyone who wants a fast first pass before a full SEO audit tool

How to use it

1. Add one or more URLs to audit.
2. Optionally adjust the ideal title/description length ranges, whether to check robots.txt and sitemap.xml, and concurrency.
3. Run it once for a snapshot, or put it on an Apify Schedule to catch a dropped meta tag after a CMS or template change.

This Actor uses pay-per-event pricing:

• Page audited -- charged once per URL processed.

Parallel auditing doesn't cost more -- it just finishes faster.

FAQ

Is this a full SEO audit tool? No. It's a fast, explainable check of the on-page fundamentals -- title, description, headings, canonical, robots meta, Open Graph, and robots.txt/sitemap.xml presence. It doesn't check backlinks, keyword rankings, Core Web Vitals, or content quality.

What makes something "critical" vs. a "warning"? critical covers the two failures that mean a page effectively can't be found in search at all: the page returns an HTTP error (4xx/5xx), or a robots meta tag actively blocks indexing (noindex). warning covers everything else that lowers the score -- worth fixing, but the page can still be indexed.

Does this render JavaScript-injected tags? No. It reads the raw HTML response, the same way search engine crawlers typically do for meta tags. If your tags are injected client-side after page load, they won't be seen here.

Will higher concurrency get me rate-limited? It can, on servers with aggressive rate limiting. Start at the default (5) and lower it if you see timeouts spike for a particular site.

Does this send data anywhere besides your own Apify account? No. It only fetches the URLs you provide (and, optionally, each domain's robots.txt/sitemap.xml) and returns what it finds.
