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 ## Domain Authority & SEO Checker Analyze domains in bulk and get a comprehensive SEO health report. No browser needed — pure Python, fast and efficient. ### What it does For each domain, the Actor checks: - **Domain Score** (0-100) — proprietary score based on all collected metrics - **HTTP Status** — reachability and response codes - **Page Load Time** — response time in milliseconds - **SSL Certificate** — validity, issuer, expiration date - **DNS Records** — A, AAAA, MX, NS, TXT, CNAME - **Domain Age** — registration date via WHOIS - **Meta Tags** — title, description, Open Graph tags - **Technology Detection** — server software, frameworks, CDN - **Robots.txt** — existence check - **Sitemap.xml** — existence and URL count - **Social Links** — social media profiles found on homepage ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `domains` | string[] | `[]` | List of domains to check (no protocol needed) | | `csvUrl` | string | `null` | URL to a CSV file with domains | | `maxConcurrency` | integer | `10` | Parallel checks (1-50) | | `timeout` | integer | `15` | HTTP timeout in seconds (5-60) | | `includeMetaTags` | boolean | `true` | Extract meta tags | | `includeDns` | boolean | `true` | Lookup DNS records | | `includeSsl` | boolean | `true` | Check SSL certificates | | `includeTechDetection` | boolean | `true` | Detect technologies | #### Example input ```json { "domains": ["example.com", "google.com", "github.com"], "maxConcurrency": 10, "timeout": 15 } ```` ### Output Each domain produces a result object: ```json { "domain": "example.com", "domainScore": 72, "httpStatus": 200, "loadTimeMs": 450, "ssl": { "valid": true, "issuer": "Let's Encrypt", "expiresAt": "2026-09-15" }, "dns": { "aRecords": ["93.184.216.34"], "mxRecords": ["mail.example.com"], "nsRecords": ["ns1.example.com"] }, "domainAge": { "createdAt": "1995-08-14", "ageYears": 31 }, "meta": { "title": "Example Domain", "description": "This domain is for use in illustrative examples..." }, "technology": { "server": "nginx", "poweredBy": null, "cdn": "Cloudflare", "frameworks": [] }, "robotsTxt": true, "sitemapXml": true, "sitemapUrls": 1250, "socialLinks": ["https://twitter.com/example"], "checkedAt": "2026-04-07T12:00:00+00:00" } ``` ### Domain Score The Domain Score (0-100) is calculated from: | Factor | Max Points | |--------|-----------| | HTTP reachable & fast | 20 | | Valid SSL certificate | 15 | | Domain age | 15 | | DNS health (MX, NS, A) | 10 | | Sitemap exists + URL count | 10 | | Meta tags quality | 10 | | Robots.txt exists | 5 | | Technology detected | 5 | | Social media presence | 5 | ### Pricing This Actor uses the pay-per-event model: - **$0.003 per domain checked** ($3 per 1,000 domains) ### Use cases - **SEO audits** — bulk-check client domains - **Competitor analysis** — compare domain health metrics - **Lead qualification** — score prospect websites - **Domain prospecting** — evaluate domains before purchase - **Website monitoring** — periodic health checks # Actor input Schema ## `domains` (type: `array`): List of domains to check (e.g., example.com, google.com). No protocol needed. ## `csvUrl` (type: `string`): URL to a CSV file with domains (one per line or in the first column). Used in addition to the domains list. ## `maxConcurrency` (type: `integer`): Maximum number of domains to check simultaneously. ## `timeout` (type: `integer`): HTTP request timeout in seconds per domain. ## `includeMetaTags` (type: `boolean`): Extract title, description, and Open Graph tags from the homepage. ## `includeDns` (type: `boolean`): Lookup A, AAAA, MX, NS, TXT, and CNAME records. ## `includeSsl` (type: `boolean`): Check SSL certificate validity, issuer, and expiration. ## `includeTechDetection` (type: `boolean`): Detect server software and technologies from HTTP headers. ## Actor input object example ```json { "domains": [ "example.com", "google.com" ], "maxConcurrency": 10, "timeout": 15, "includeMetaTags": true, "includeDns": true, "includeSsl": true, "includeTechDetection": true } ``` # 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 = { "domains": [ "example.com", "google.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("zhorex/domain-authority-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 📖?
