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 ## SEO & Broken Link Auditor Apify Actor that crawls a website and produces a detailed SEO and link health report. Built with **TypeScript**, **Crawlee CheerioCrawler**, and the **Apify SDK**. ### Features - **Site crawler** – discovers pages from seed URLs with optional same-domain restriction - **Broken link detection** – checks outbound links for 4xx/5xx errors and timeouts - **Redirect tracking** – reports links that redirect to a different final URL - **SEO on-page audit** per page: - `brokenLinks[]` - `redirects[]` - `duplicateTitles` - `missingDescription` - `missingH1` - `canonicalIssues` - `sitemapUrl` - `robotsMeta` - `imagesMissingAlt[]` - `responseTimeMs` - **Aggregated summary dataset items** grouped by issue type - **Full JSON report** saved to key-value store as `OUTPUT` - **Retries**, **rate limiting**, and structured **logging** ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `startUrls` | array | `https://crawlee.dev` | Seed URLs to start crawling | | `maxPages` | integer | `50` | Maximum pages to crawl | | `sameDomain` | boolean | `true` | Only follow links on the same domain | #### Example input ```json { "startUrls": [{ "url": "https://example.com" }], "maxPages": 100, "sameDomain": true } ```` See also [`examples/input.json`](./examples/input.json). ### Output #### Per-page dataset items (`recordType: "page"`) ```json { "recordType": "page", "url": "https://example.com/about", "title": "About Us", "statusCode": 200, "responseTimeMs": 342, "brokenLinks": [ { "url": "https://example.com/old-page", "anchorText": "Old page", "statusCode": 404, "error": "HTTP 404" } ], "redirects": [ { "url": "https://example.com/redirect-me", "anchorText": "Redirect", "statusCode": 301, "redirectChain": ["https://example.com/redirect-me"], "finalUrl": "https://example.com/new-page" } ], "duplicateTitles": [ { "title": "Home", "urls": ["https://example.com/", "https://example.com/home"] } ], "missingDescription": false, "missingH1": false, "canonicalIssues": [], "sitemapUrl": "https://example.com/sitemap.xml", "robotsMeta": "index, follow", "imagesMissingAlt": [], "scrapedAt": "2026-07-05T12:00:00.000Z" } ``` #### Summary dataset items (`recordType: "summary"`) Summary items are emitted for: - `overview` - `broken-links` - `redirects` - `duplicate-titles` - `missing-description` - `missing-h1` - `canonical-issues` - `images-missing-alt` #### Full JSON report The complete audit is also stored in the default key-value store under **`OUTPUT`**: ```json { "generatedAt": "2026-07-05T12:00:00.000Z", "pagesScanned": 25, "linksChecked": 412, "summary": { "totalBrokenLinks": 3, "totalRedirects": 8, "pagesMissingDescription": 2, "pagesMissingH1": 1, "pagesWithCanonicalIssues": 4, "totalImagesMissingAlt": 6, "duplicateTitleGroups": 1, "averageResponseTimeMs": 285 }, "pages": [], "summaries": [] } ``` ### Pricing This Actor is designed for **pay-per-result** pricing at **$0.005 per dataset item**. When publishing to Apify Store, configure the synthetic event: - **Event:** `apify-default-dataset-item` - **Price:** `$0.005` Each page audit and summary item pushed to the default dataset counts as one result. ### Local development ```bash cd D:\Apify\factory\seo-broken-link-auditor npm install apify run ``` Run with the example input: ```bash cp examples/input.json storage/key_value_stores/default/INPUT.json apify run ``` Build TypeScript: ```bash npm run build ``` Run tests: ```bash npm test ``` ### Deploy ```bash apify login apify push ``` After pushing, enable monetization in Apify Console and set `apify-default-dataset-item` to **$0.005**. ### Project structure ```text .actor/ ├── actor.json ├── dataset_schema.json ├── input_schema.json └── output_schema.json examples/ └── input.json src/ ├── crawl-state.ts ├── link-checker.ts ├── main.ts ├── routes.ts ├── seo-analyzer.ts ├── types.ts └── url-utils.ts ``` ### How it works 1. The crawler starts from `startUrls` and follows internal links up to `maxPages`. 2. Each page is parsed with Cheerio to extract SEO signals and outbound links. 3. Outbound links are checked with HTTP HEAD/GET requests (cached, rate-limited, retried). 4. `robots.txt` is scanned for sitemap URLs on the first crawled page. 5. After crawling, duplicate titles are computed across all audited pages. 6. Per-page results and summary items are saved to the dataset; the full report is saved to `OUTPUT`. # Actor input Schema ## `startUrls` (type: `array`): Seed URLs to begin the site crawl and SEO audit. ## `maxPages` (type: `integer`): Maximum number of pages to crawl and audit. ## `sameDomain` (type: `boolean`): When enabled, the crawler only follows links on the same domain as the start URLs. ## Actor input object example ```json { "startUrls": [ { "url": "https://crawlee.dev" } ], "maxPages": 50, "sameDomain": true } ``` # Actor output Schema ## `dataset` (type: `string`): No description ## `report` (type: `string`): No description # API You can run this Actor programmatically using our API.
