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 ## Free Backlink Checker for Website — Domain Authority Score The free backlink checker for any website. Get the **domain authority score**, **referring domain count**, **total link count**, **follow %**, plus up to 900 individual backlink records — origin URL, target URL, anchor text, rel, type, status, first/last seen. A free SEO backlink checker tool. No login required, no Ahrefs or Semrush subscription needed. ### What you get Per run (one domain in, one item out): - `domain_score` — authority score (0-100, like Ahrefs DR / Moz DA) - `referring_domains_count` — unique linking domains - `total_link_count` — all backlinks (multiple from same domain counted) - `follow_percent` — % of links passing PageRank - `ip_count` — unique IPs of linking servers - `meta_title` — homepage title (sanity check) - `thumbnail` — homepage screenshot URL - `backlinks[]` — array of per-link records (when `include_backlinks=true`) Each backlink record: ```json { "origin_url": "https://example-publisher.com/article", "target_url": "https://your-domain.com/page", "anchor_text": "click here", "rel": "follow", "type": "text", "status": "found", "first_seen": "2025-08-12", "last_seen": "2026-04-20" } ```` ### Why this free backlink checker beats paid SEO tools Ahrefs charges $99-$399/month. Semrush charges $129-$449/month. Both require account creation, billing setup, and have monthly quota caps. This Actor: - Returns **the same shape of data** — domain score, referring domains, full backlink list — for any domain - Has **no monthly subscription** — pay only for the domains you check - Has **no quota cap** — run as many domains as you need - Returns **up to 900 backlinks per domain** — comparable to Ahrefs free tier ### Input | Field | Default | Description | |---|---|---| | `domain` | required | Bare domain (e.g. `coolblue.nl` or `example.com`) | | `include_backlinks` | true | Set false for summary only (faster, smaller payload) | | `timeout` | 60 | Request timeout in seconds (10-180) | ### Use cases - **SEO audit** — score any domain's link profile vs competitors - **Competitor backlink analysis** — pull a competitor's full backlink list, sort for sites that link to multiple competitors but not you - **Outreach research** — find publishers who already link in your category - **Pre-acquisition due diligence** — verify a domain's backlink claims - **Lead enrichment** — score every prospect's authority before outreach ### Limits - Returns up to ~900 per-link records per domain (free-tier cap) - Domain authority score is directionally correct vs Ahrefs DR / Moz DA but not identically calibrated — use for relative comparisons, not drop-in replacement ### Related Actors — Free SEO Suite This actor pairs with two other free tools for a complete SEO research workflow: - **[Free Keyword Research Tool for SEO](https://apify.com/s-r/google-keywords)** — volume + CPC + SEO difficulty + intent for any seed keyword - **[Free URL to Markdown API](https://apify.com/s-r/markdown-anything)** — bulk-extract competitor pages as clean markdown for LLM-driven analysis Use this actor to score competitor authority, the keyword tool to find their winning queries, and the markdown converter to bulk-pull their ranking pages for content gap analysis. # Actor input Schema ## `domain` (type: `string`): Domain to analyze (e.g. "coolblue.nl" or "example.com"). Required. ## `include_backlinks` (type: `boolean`): If false, returns only the domain-level summary (faster, smaller payload). ## `timeout` (type: `integer`): How long to wait for the backlink lookup (default 60). ## Actor input object example ```json { "domain": "shoppingscraper.com", "include_backlinks": true, "timeout": 60 } ``` # 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 = { "domain": "shoppingscraper.com" }; // Run the Actor and wait for it to finish const run = await client.actor("s-r/backlinks-checker").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 📖?
