Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Hreflang Tags Auditor Fetches one public web page and audits its `rel="alternate" hreflang` tags for international SEO QA. The actor reports discovered alternate URLs, duplicate language targets, invalid values, missing `x-default`, missing self-reference, and a simple readiness score. ### Use cases - Check localized landing pages before a site launch or migration. - Monitor important international SEO pages on a schedule. - Add hreflang QA to agency audit reports and technical SEO workflows. - Feed structured hreflang diagnostics into internal dashboards. ### Input | Field | Type | Required | Description | | --- | --- | --- | --- | | `startUrl` | string | Yes | Public HTTP or HTTPS page URL to audit. Credentials and private network targets are rejected. | | `timeoutSeconds` | integer | No | Request timeout in seconds. Defaults to 10. Allowed range: 3 to 30. | ### Output Each run pushes one dataset item. | Field | Type | Description | | --- | --- | --- | | `inputUrl` | string | URL submitted in the input. | | `normalizedInputUrl` | string | URL after adding a default HTTPS scheme when needed. | | `finalUrl` | string | Final URL after safe HTTP redirects. | | `status` | integer or null | HTTP status returned by the final page. | | `ok` | boolean | True when the final fetch returned a 2xx or 3xx status and no fetch error occurred. | | `checkedAt` | string | ISO 8601 timestamp for the audit. | | `canonicalUrl` | string or null | Canonical URL found in the page head, if present. | | `tagCount` | integer | Number of hreflang alternate tags found. | | `uniqueHreflangCount` | integer | Number of unique hreflang values found. | | `hasXDefault` | boolean | Whether an `x-default` tag is present. | | `hreflangTags` | array | Objects with `hreflang` and absolute `href` values. | | `score` | integer | Readiness score from 0 to 100. | | `grade` | string | Letter grade from A to F. | | `issues` | array | Detected problems. | | `recommendations` | array | Suggested fixes. | | `error` | string or null | Fetch or validation error, if any. | ### Example input ```json { "startUrl": "https://example.com/en/", "timeoutSeconds": 10 } ```` ### Example output ```json { "inputUrl": "https://example.com/en/", "normalizedInputUrl": "https://example.com/en/", "finalUrl": "https://example.com/en/", "status": 200, "ok": true, "checkedAt": "2026-07-09T00:00:00.000Z", "canonicalUrl": "https://example.com/en/", "tagCount": 3, "uniqueHreflangCount": 3, "hasXDefault": true, "hreflangTags": [ { "hreflang": "en", "href": "https://example.com/en/" }, { "hreflang": "fr-fr", "href": "https://example.com/fr/" }, { "hreflang": "x-default", "href": "https://example.com/" } ], "score": 100, "grade": "A", "issues": [], "recommendations": [], "error": null } ``` ### Security The actor only fetches public HTTP and HTTPS URLs. It rejects URL credentials, localhost and private IP literals, and hostnames that resolve to private IPv4 or IPv6 ranges. Redirect targets are validated before being followed. Response bodies are capped at 2 MB. ### Pricing Suggested pay-per-event pricing: | Event | Price | | --- | ---: | | Actor start | $0.005 | | Page audited | $0.010 | At this pricing, a single page audit costs about $0.015 before Apify platform fees. ### FAQ #### Does this crawl an entire website? No. It audits one submitted page per run. This keeps runs fast, predictable, and easy to price. #### Does it verify reciprocal hreflang links? No. It checks the tags present on the submitted page. Reciprocal cluster crawling can be added later if customer demand justifies the extra network requests and cost. #### Does it require login or cookies? No. It only works with public unauthenticated pages. #### What happens when a page has no hreflang tags? The actor returns a low score, an issue explaining that no hreflang tags were found, and a recommendation to add tags when the page targets multiple languages or regions. # Actor input Schema ## `startUrl` (type: `string`): Public HTTP or HTTPS page URL to audit.
