SEO Meta Tags Auditor

Fetches one public web page and returns a structured audit of SEO and social preview metadata. It checks the title tag, meta description, canonical link, robots meta directives, viewport, Open Graph, Twitter Card, hreflang alternates, and JSON-LD structured data presence.

Use cases

• Technical SEO QA before launches and migrations.
• Agency checks for client landing pages and product pages.
• Content operations validation before publishing campaigns.
• Programmatic monitoring for missing social preview tags.
• Developer tooling that needs a simple SEO metadata API result.

Security

The actor only fetches public HTTP and HTTPS URLs. It rejects unsupported schemes, URL credentials, private IP literals, and hostnames that resolve to private network addresses. Redirect targets are revalidated before fetching. Response size is capped to reduce resource abuse.

Pricing

Suggested pay-per-event pricing:

Event	Suggested price
Actor start	$0.005
Page audited	$0.01

This keeps one-page checks inexpensive while allowing agencies and monitoring workflows to pay according to usage.

Store listing notes

Target users: SEO agencies, technical SEO consultants, site migration QA teams, content operations teams, and developer-tool builders.

Store keywords: SEO meta tags API, meta description checker, Open Graph checker, Twitter Card checker, canonical tag checker, hreflang checker, JSON-LD audit, SEO QA automation.

Competitor weakness: many SEO tools expose this as a web UI or a broad crawler feature. This actor is a small API-first product that returns one normalized JSON record suitable for workflows, scheduled checks, and client reporting.

Kill or keep metric: keep if it receives organic Store impressions, runs, revenue, or inbound interest within 60 to 90 days. Improve the listing or pricing if impressions arrive without runs. Archive if it gets no discovery and no usage.

FAQ

Does this crawl an entire website?

No. It audits one page per run. This keeps the actor fast, predictable, and easy to price per result.

Does it require login credentials?

No. It is designed for public pages only and rejects URLs containing credentials.

Does a warning always mean the page is wrong?

No. Some warnings are contextual. For example, hreflang is only required for multilingual sites, and JSON-LD is only relevant when structured data applies to the page.

Can this be scheduled?

Yes. Use Apify schedules to monitor important pages and export dataset results to your reporting or alerting workflow.
