You are not charged for the Apify platform usage, but only a fixed price for specific events.

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.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.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/platform/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 ## Public Localization & International SEO Signal Agent Analyze public pages for international SEO signals: `hreflang`, `x-default`, HTML language, content language, Open Graph locale, canonical alignment, language switcher links, locale matrix evidence, risk labels, and stable change hashes. This Actor is built for AI agents, SEO teams, localization teams, site migration checks, market researchers, and report generators that need compact, source-linked localization evidence without running a browser or crawling an entire website. ### What It Returns - `hreflang` alternate links with locale, language, region, URL, same-site status, and source evidence. - `x-default`, `html lang`, `content-language`, `og:locale`, and `og:locale:alternate` signals. - Language switcher links inferred from visible anchors and locale-like URL paths. - A locale matrix summary with detected language count, region count, same-site alternates, external alternates, and current page locale hints. - Risk labels for missing `x-default`, duplicate locale declarations, missing HTML language, external alternates, and canonical/hreflang alignment issues. - `missingFields`, `confidenceScore`, `completenessScore`, `localizationScore`, recommended next action, evidence snippets, evidence URLs, and a stable `localizationHash`. ### Pricing Behavior The Actor uses pay-per-event pricing and only charges the useful result event when it finds useful public localization SEO evidence. It does not charge the useful event for: - invalid or private-network URLs; - failed fetches; - pages with no useful localization signals; - `focusLocales` misses; - unchanged records when you pass a previous `localizationHash`. `apify-default-dataset-item` is intentionally not used. ### Scope And Safety - Public HTTP/HTTPS pages only. - Private-network hosts, credentials, query strings, fragments, path parameters, and token-like account paths are rejected. - JavaScript is not executed. - Sitemap files, Google results, rankings, screenshots, external assets, and alternate pages are not fetched. - Alternate URLs are recorded as evidence from the current page only. - Output is evidence-based and should be reviewed before making production SEO changes. ### Example Input ```json { "pageUrls": [ "https://www.cloudflare.com" ], "focusLocales": [ "en", "fr", "de", "ja", "zh" ], "requestTimeoutSecs": 20 } ```` ### Best Use Cases - Check whether a public homepage or localized page declares a healthy `hreflang` matrix. - Find missing `x-default` or canonical/hreflang alignment risks before migration. - Feed AI agents structured localization evidence instead of raw HTML. - Monitor international SEO signal changes without paying for unchanged results. # Actor input Schema ## `pageUrls` (type: `array`): Public HTTP/HTTPS homepage or localized page URLs. Query parameters, fragments, credentials, path params, private-network hosts, and token-like account paths are rejected. ## `focusLocales` (type: `array`): Optional languages or locales that must appear in detected evidence before the useful result event is charged, such as en, en-US, fr, de, es, ja, or zh-CN. ## `previousLocalizationRecords` (type: `array`): Optional previous records from this Actor. If the stable localizationHash is unchanged, the result is written without charging the useful event. ## `requestTimeoutSecs` (type: `integer`): Maximum time in seconds to wait for the public page response. ## Actor input object example ```json { "pageUrls": [ "https://www.mozilla.org" ], "focusLocales": [], "previousLocalizationRecords": [], "requestTimeoutSecs": 20 } ``` # Actor output Schema ## `datasetId` (type: `string`): No description # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("jacksu/public-localization-seo-signal-agent").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
