## What's an Apify Actor?
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 Site Auditor — Full On-Page Audit with Scores & Broken Link Checker
Crawl any website and get a **complete on-page SEO audit of every page**: a **0–100 SEO score**, a prioritized issue list (errors / warnings / notices), **broken link detection**, meta tag analysis, heading structure, structured data, Open Graph, mobile-readiness and basic performance signals — in clean JSON/CSV you can hand to a client or pipe into a dashboard.
Built for **agencies, freelancers, in-house SEO teams and site owners** who want repeatable, schedulable technical audits without a $100+/mo SaaS subscription.
### What it checks on every page
| Category | Checks |
|---|---|
| **Indexing** | HTTP status, noindex flags, canonical URL, redirect chains |
| **Meta tags** | Title presence & length, meta description presence & length, charset, viewport (mobile) |
| **Content** | H1/H2 structure, word count, thin content detection, text-to-HTML ratio, `lang` attribute |
| **Links** | Internal/external counts, **broken links (404/410/5xx/dead hosts)** — each unique link checked once per run |
| **Media** | Images missing alt text |
| **Social** | Open Graph (og:title/description/image), Twitter card |
| **Structured data** | JSON-LD blocks and their schema.org types |
| **Security** | HTTPS usage, mixed content on secure pages |
| **Performance** | Server response time, HTML document size |
Every issue comes with severity and a human-readable message; every page gets a score, and results are sorted **worst pages first** so you know where to start.
### Input example
```json
{
"startUrls": ["https://your-website.com"],
"crawlWebsite": true,
"maxPages": 100,
"checkBrokenLinks": true
}
````
### Output example (one page)
```json
{
"url": "https://your-website.com/pricing",
"score": 76,
"statusCode": 200,
"title": "Pricing",
"titleLength": 7,
"metaDescription": null,
"h1Count": 1,
"brokenLinkCount": 2,
"brokenLinks": [{ "url": "https://your-website.com/old-page", "status": 404 }],
"imagesWithoutAlt": 3,
"wordCount": 420,
"jsonLdTypes": ["Organization"],
"issues": [
{ "severity": "error", "code": "missing-meta-description", "message": "Page has no meta description." },
{ "severity": "error", "code": "broken-links", "message": "2 broken links found on this page." },
{ "severity": "warning", "code": "short-title", "message": "Title is only 7 characters (recommended 30–60)." }
]
}
```
### Use cases
- **Client audits & reports** — run once, export CSV, deliver a prioritized fix list.
- **Continuous monitoring** — schedule weekly; diff scores over time and alert on regressions via Apify integrations (Slack, email, webhooks).
- **Pre-launch QA** — catch noindex flags, broken links and missing metas before a site goes live.
- **Migration verification** — crawl after a redesign/replatform and compare against the old baseline.
### Scheduling & integrations
Run on a [schedule](https://docs.apify.com/platform/schedules), export **JSON, CSV, Excel**, or connect **Google Sheets, Zapier, Make, Slack, webhooks** and the [Apify API](https://docs.apify.com/api/v2). MCP-compatible for AI agents.
### FAQ
**Does it render JavaScript?**
No — it audits server-rendered HTML, which is also what search engine crawlers parse first. This keeps audits fast and affordable. JS-only content will show as thin content, which is itself a useful SEO signal.
**How is the score calculated?**
Errors cost 12 points, warnings 6, notices 2, from a base of 100. The formula is consistent across runs, so scores are comparable over time.
**Will it crawl the whole site?**
It follows internal links from your start URLs up to `maxPages`. Subdomains are treated as separate sites (not followed).
# Actor input Schema
## `startUrls` (type: `array`):
Pages to audit. With Crawl website enabled, the actor also follows same-domain links from these pages.
## `crawlWebsite` (type: `boolean`):
Follow internal links from the start URLs and audit every discovered page (up to Max pages). Disable to audit only the exact URLs provided.
## `maxPages` (type: `integer`):
Maximum number of pages to audit per run.
## `checkBrokenLinks` (type: `boolean`):
Verify every internal link found on audited pages and report dead links (404/410/5xx) per page. Each unique link is checked only once per run.
## `checkExternalLinks` (type: `boolean`):
Extend the broken-link check to external (outbound) links. Slower on link-heavy sites.
## `proxyConfiguration` (type: `object`):
Proxy for requests. Apify Proxy (automatic) is recommended for reliable crawling.
## Actor input object example
```json
{
"startUrls": [
"https://example.com"
],
"crawlWebsite": true,
"maxPages": 50,
"checkBrokenLinks": true,
"checkExternalLinks": false,
"proxyConfiguration": {
"useApifyProxy": true
}
}
```
