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 Crawler — On-Page SEO Analyzer & Spider 🔍 **Audit the on-page SEO of an entire website in one run.** This **SEO crawler / SEO spider** crawls a whole site and runs a full **on-page SEO audit on every page** — titles, meta descriptions, headings, canonical tags, robots/indexability, Open Graph, schema.org types, word count, image alt coverage and internal/external link counts — plus a ready-made list of **detected SEO issues**. Point it at one URL and it audits thousands of pages automatically. **No login, no headless browser, one row per page.** > Looking for a **technical SEO audit tool**, **on-page SEO checker**, **meta tag checker**, **title tag checker** or a **bulk website SEO analyzer**? This actor does the full crawl-and-audit at scale. --- ### ✨ Key features - 🕷️ **Full-site crawl** — start from one URL and follow internal links across the whole domain. - 🏷️ **Complete on-page data** — title, meta description, H1/H2, canonical, robots, Open Graph, Twitter cards, hreflang, charset, viewport. - 🧱 **Structured data detection** — extracts schema.org `@type`s from JSON-LD. - 🚩 **Automatic issue flags** — missing titles, duplicate/multiple H1, thin content, missing meta, missing canonical, noindex, images without alt, and more. - 🔢 **Quality metrics** — honest word count (boilerplate removed), image alt coverage, internal/external link counts. - ⚡ **Fast & cheap** — pure HTTP, no browser, high concurrency. ### 💡 Use cases - **Technical SEO audits** — surface on-page issues across a whole site in a single run. - **Content audits** — spot thin content, missing meta descriptions and duplicate titles. - **Pre-launch QA** — verify titles, canonicals and indexability before going live. - **SEO monitoring** — schedule the crawl and track on-page SEO health over time. - **Migration checks** — confirm meta, canonicals and indexability survived a redesign. ### 📦 What you get One row per page, including: | Field | Description | |-------|-------------| | `url`, `statusCode` | Page URL and HTTP status | | `title`, `titleLength` | Title tag and its length | | `metaDescription`, `metaDescriptionLength` | Meta description and length | | `h1`, `h1Count`, `h2Count` | Headings | | `canonical`, `metaRobots`, `isIndexable` | Indexability signals | | `lang`, `charset`, `hasViewport`, `hreflangCount` | Technical tags | | `wordCount` | Body word count (boilerplate removed) | | `imagesCount`, `imagesMissingAlt` | Image alt coverage | | `internalLinks`, `externalLinks` | Link counts | | `ogTitle`, `ogDescription`, `ogImage`, `twitterCard` | Social tags | | `schemaTypes` | Detected schema.org `@type`s | | `issues` | Detected on-page SEO problems | #### Detected issues `missing-title`, `title-too-long`, `title-too-short`, `missing-meta-description`, `meta-description-too-long`, `meta-description-too-short`, `missing-h1`, `multiple-h1`, `missing-canonical`, `noindex`, `images-missing-alt`, `missing-viewport`, `thin-content`. #### Example output ```json { "url": "https://example.com/blog/post", "statusCode": 200, "title": "How to Do On-Page SEO", "titleLength": 22, "metaDescriptionLength": 0, "h1": ["How to Do On-Page SEO"], "h1Count": 1, "wordCount": 1240, "imagesMissingAlt": 3, "internalLinks": 41, "externalLinks": 6, "schemaTypes": ["Article", "BreadcrumbList"], "issues": ["missing-meta-description", "images-missing-alt"] } ```` ### 🚀 How to use it 1. Click **Try for free / Start**. 2. Paste one or more website URLs into **Start URLs**. 3. (Optional) Set **Max pages to crawl** — `0` to audit the whole site. 4. Click **Save & Start**. 5. Export the audit as **JSON, CSV, Excel or via API**, and sort/filter by the `issues` column. ### ⚙️ Input | Option | Description | Default | |--------|-------------|---------| | `startUrls` | Websites to crawl | – (required) | | `maxPagesToCrawl` | Max pages per run (`0` = whole site) | `1000` | | `maxConcurrency` | Parallel requests | `10` | #### Example input ```json { "startUrls": [{ "url": "https://example.com" }], "maxPagesToCrawl": 5000 } ``` ### 🔍 How it works The crawler follows internal links within the same domain as your Start URLs and analyzes the server-rendered HTML of each page: it reads all on-page SEO tags, counts headings/links/images, computes a boilerplate-free word count, detects schema.org types, and flags common SEO issues. Pure HTTP — fast and cheap, no headless browser. ### 🧰 Tips & best practices - Sort or filter by the `issues` field to build a prioritized SEO fix-list. - Use `titleLength` / `metaDescriptionLength` to catch tags that will be truncated in search results. - Filter `isIndexable: false` to find pages accidentally set to `noindex`. - Set `maxPagesToCrawl` to `0` for a complete site audit; schedule it to monitor SEO health. ### ❓ FAQ **Does it render JavaScript?** No — it audits server-rendered HTML, which is what search engines index first, and keeps runs fast and cheap. **Does it detect structured data?** Yes — it extracts schema.org `@type`s from JSON-LD on each page. **How is `wordCount` calculated?** From the body text after removing scripts, styles, nav, header, footer and sidebars — an honest content word count. **How do I audit the whole site?** Set `maxPagesToCrawl` to `0`. **What formats can I export?** JSON, CSV, Excel, HTML and a full REST API. ### 🔗 Related actors by the same author - **Broken Link Checker** — crawl a site and find dead links with HTTP status codes. - **Website Link Graph & Outbound Links Crawler** — map internal & outbound links. - **JSON-LD Schema & Meta Tag Extractor** — deep structured-data & meta extraction per URL. - **Sitemap to URL Crawler** — extract all URLs from any sitemap.xml. *** ### Changelog - **2026-05-25** — Maintenance & reliability pass: pulled the latest source and rebuilt the Actor on the current base image; build verified. *Last reviewed: 2026-05-25.* # Actor input Schema ## `startUrls` (type: `array`): Websites to crawl.
