SEO Page Audit — tags, headings, structured data and links

Give it page URLs; it returns an on-page SEO audit of each: title and meta description (presence and length), canonical, robots meta and X-Robots-Tag, hreflang, heading outline, Open Graph and Twitter card tags, JSON-LD and microdata items with required-property checks for common schema.org types, images missing alt text, internal and external link counts, word count, viewport and language, mixed content, status and redirects — as findings with severity.

Development validation produced actual successful public-input records using the production Dockerfile and SDK entrypoint on GitHub-hosted Linux. The smoke input, all three tasks and every defined benchmark passed their exact expectations. The independent review completed on 2026-10-19; its findings are tracked in the committed fix report. Platform costs, settlement, publication and daily tests remain unverified.

Call it from an agent

Through Apify's MCP server (https://mcp.apify.com) use call-actor:

{
  "actor": "hermeskd/seo-page-audit",
  "input": {
    "urls": [
      "https://docs.apify.com/platform/actors/publishing/monetize"
    ]
  },
  "callOptions": {
    "maxTotalChargeUsd": 0.05,
    "timeout": 600
  },
  "waitSecs": 30
}

Then call get-dataset-items with the returned defaultDatasetId. Dedicated tool URL: https://mcp.apify.com?tools=hermeskd/seo-page-audit

Input

Field	Type	Meaning
urls	array	Public HTTP(S) URLs to process; errors are uncharged.
render	string	auto renders sparse HTML; never audits static HTML; always audits the rendered DOM.

Output

Field	Meaning
url	Input URL.
finalUrl	URL after redirects.
ok	True for a readable audit, including pages with SEO findings.
status	Final HTTP status.
findings	Actionable observations; length checks are editorial heuristics.
summary	Finding counts by severity.
meta	Title, description, canonical, robots, language, viewport, hreflang and social metadata.
headings	Document heading outline.
structuredData	Types and profile validation only; unknown types valid=null; no contact values returned.
links	HTTP(S) link counts.
wordCount	Words in visible static/rendered text, excluding scripts and styles.
imagesMissingAlt	Images without an alt attribute; decorative empty alt is accepted.
error	Failure, always uncharged.

Actual production-container record from 2026-10-18T20:25:04.510238+00:00 (code f063187693578dd7551fa2bec552281e2f0f3e33, smoke input, SDK local storage). The saved record is unchanged; local event logs do not prove Apify settlement.

Events and prices

Event	Title	Charged when	FREE / BRONZE	SILVER	GOLD / PLATINUM / DIAMOND
page-audited	Page audited	One successfully fetched and audited HTML page.	$0.004	$0.0036	$0.0032

Platform usage is not passed through. Apify's automatic actor-start event remains $0.00005 per started GB (one GB or less counts once). The synthetic dataset-item event is absent. Charge limits stop further paying work; unprocessed inputs receive uncharged errors. Completed readable pending events are settled on abort.

Worked cost example: ten successful primary events cost $0.04 at list, plus actor start. Failures are not included in that count.

Limits and run time

1–100 URLs; 10 MiB per HTML response. auto renders HTML with fewer than 200 static words, never parses static HTML only, always audits the rendered DOM. Actual HTML is requested; Markdown and files are rejected, uncharged. Title length 30–60 and description length 50–160 are editorial heuristics, not ranking guarantees. Structured-data profiles cover Article, NewsArticle, BlogPosting, Organization, BreadcrumbList and ListItem. Article/Organization currently have no required properties. Unknown types have valid=null; no complete schema.org or rich-result eligibility claim. Up to 1,000 structured nodes and depth 50.

Default run timeout is 600 seconds. Typical cold platform time, costs and the smallest passing memory have not been measured for this new implementation. Memory probes are evidence to collect later; configured memories are specification defaults, not measured claims.

Errors

Code	Meaning
download_failed	The request or connection failed within its bounded deadline.
http_error	The source answered an unsuccessful HTTP status.
unsupported_content_type	An HTML audit/crawl received a non-HTML representation.
too_large	A documented response, expansion or traversal cap was exceeded.
robots_disallowed	robots.txt forbids fetching the URL; no request was made to it.
blocked_host	The host is on the deny-list or resolves to a private or local address; no request was made.
login_required	The page is a sign-in wall; no authentication is attempted.
timeout	The input did not finish within the run's time budget.
internal_error	Unexpected failure; the message carries the error class.
charge_limit_reached	The run reached its maximum total charge; this input was not processed.
invalid_input	The run input passed the input schema but cannot be used; the message names the field.

No failure record is charged. A run fails only when all input outcomes are Actor-side failures; caller errors and a mixture of caller/Actor failures do not fail the run.

Sources and terms

Only process content you have the right to process. URL fetches obey HermesBot robots-group selection, the shared deny-list, public-address checks on connections and redirects, honest identity, deadlines and rate limits. No caller credentials, cookies, CAPTCHA solving, residential proxies or evasion. Public caller-named HTML is parsed directly or after guarded Chromium rendering. Structured-data required-property checks cover the documented Article, Organization and Breadcrumb profiles; unsupported types remain unassessed. No contact values from structured data are returned. The committed enumeration records the Google Search guidance used for those profiles.

Not affiliated

This Actor is not affiliated with Google, Apify, IANA, Verisign or other named protocol/source providers. Third-party names describe compatibility and source material.

Changelog

2026-10-17 (historical): initial implementation and fixture contracts; packaging and public production validation were incomplete on that date.

2026-10-18: all six production images, public smoke inputs, three tasks per Actor and defined benchmarks passed on GitHub-hosted Linux; exact code, records and image provenance are retained with the examples. These local SDK runs do not prove platform costs, settlement, publication, minimum memory, daily tests or payouts.

2026-10-19: independent-review repairs cover DNS privacy, malformed publisher URLs, empty sitemap failures, responsive assets and schema prefill, as applicable to this Actor. See the committed unit 4 fix report for measured verification and remaining platform NO-COVERAGE.
