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 ## Website SEO Audit — On-Page Analyzer for Title, Meta, Core Web Vitals & Issues **Audit any page's on-page SEO in seconds — or crawl a whole site. Get the title, meta description, headings, link counts, word count, Core Web Vitals, an on-page score, and a prioritized list of issues — for one URL, a list, or an entire website.** Two modes: **instant** (audit the exact URLs you give it) and **crawl** (point it at a domain and it crawls the site, returns a per-page audit, and a site-wide summary). Perfect for site audits, client reports, migrations, and pre-publish QA. --- ### Two modes - **Instant** — paste a list of page URLs; get one audit row per URL. - **Crawl** — give one starting URL/domain + a page cap (up to 50); get a per-page audit for every crawled page **plus** a site-summary row (avg score, pages with issues, broken links, 4xx/5xx counts). ### What you get per page - 🏅 **On-page score (0–100)** — overall health at a glance. - 🏷️ **Title & meta description** — text + length, plus duplicate-title / duplicate-description flags. - 🔠 **H1 & headings** — first H1 and heading count. - 🔗 **Internal, external & broken links** — link structure and broken-link count. - 🧱 **Word count, canonical, HTTPS, structured-data presence, redirect flag**. - ⚡ **Core Web Vitals & timing** — TTFB, DOM complete, LCP, CLS, total load time, HTTP status. - 🚩 **Issue list** — missing titles/descriptions, no H1, missing alt text, slow load, redirects, 4xx/5xx, and more. ### What you get for the whole site (crawl mode) - Site **on-page score** and average page score. - **Pages crawled**, pages with issues, 4xx/5xx page counts. - Site-wide **broken links / broken resources**, duplicate titles & descriptions. ### Perfect for - **SEO audits** — bulk-check a whole site or a content batch. - **Client reports** — export a clean, professional issue list. - **Pre-publish QA** — catch missing meta and broken pages before they go live. - **Migrations** — verify titles, canonicals, and status codes after a move. - **AI agents** — feed structured audit data into automated SEO workflows and MCP tools. ### How to use it 1. Pick a **mode**: `instant` (list of URLs) or `crawl` (one site). 2. Instant: paste your **page URLs**. Crawl: set **target** + **maxCrawlPages**. 3. Optionally enable **JavaScript rendering** for JS-heavy sites. 4. Run it — export JSON/CSV or pull via the API. #### Example input — instant ```json { "mode": "instant", "urls": ["https://example.com", "https://example.com/pricing"], "enableJavaScript": false } ```` #### Example input — crawl ```json { "mode": "crawl", "target": "https://example.com", "maxCrawlPages": 25 } ``` #### Example output (one row per page) ```json { "type": "page", "url": "https://example.com", "onpage_score": 92, "status_code": 200, "title": "Example — Home", "title_length": 14, "description_length": 0, "h1_count": 1, "word_count": 612, "internal_links": 24, "external_links": 3, "broken_links": 0, "is_https": true, "canonical": "https://example.com/", "duplicate_title": false, "largest_contentful_paint_ms": 1240, "cumulative_layout_shift": 0.02, "load_time_ms": 180, "issues": ["no_description"], "issue_count": 1 } ``` In crawl mode the first dataset row is a `site-summary` with site-wide metrics. ### Pricing Pay per page — no monthly fee, no minimum. Instant pages and crawled pages are billed per page; audit 5 pages or 5,000 and pay only for what you check. ### FAQ **Can it crawl a whole site?** Yes — use `crawl` mode with a starting URL and a page cap (up to 50). Use `instant` mode to audit a specific list of URLs. **Can it render JavaScript?** Yes — toggle JavaScript rendering for SPA/JS-heavy pages. **What issues does it detect?** Missing/long/short titles & descriptions, missing H1, missing image alt text, slow load, redirects, 4xx/5xx, and more. **Good for AI agents?** Yes — clean JSON, ideal for MCP servers, n8n, Make, and LLM agents. *** *Tags: seo audit, on-page seo, site audit, technical seo, meta tags checker, seo analyzer, page speed, seo issues, website audit, seo crawler.* # Actor input Schema ## `mode` (type: `string`): instant = audit the exact URLs you provide. crawl = crawl a whole site from one starting domain/URL. ## `urls` (type: `array`): Full page URLs to audit (include https://). One per line. Up to 1,000 per run. Used in instant mode. ## `target` (type: `string`): Starting domain or URL to crawl, e.g. https://example.com. Used in crawl mode. ## `maxCrawlPages` (type: `integer`): Maximum number of pages to crawl in crawl mode. Capped at 50. ## `enableJavaScript` (type: `boolean`): Render pages with JavaScript before auditing (slower, but accurate for JS-heavy sites). ## Actor input object example ```json { "mode": "instant", "urls": [ "https://apify.com", "https://www.python.org" ], "target": "https://apify.com", "maxCrawlPages": 25, "enableJavaScript": false } ``` # Actor output Schema ## `dataset` (type: `string`): On-page audit per URL with issues. ## `summary` (type: `string`): Pages audited and total issues. # API You can run this Actor programmatically using our API.
