## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## SEO Audit & Broken Link Checker

Crawl any website and get a **page-by-page SEO audit, a 0–100 site score and a prioritized fix list** in minutes. There's no software to install and no monthly subscription: you pay only for the pages you audit.

### What it checks on every page

| Area | Checks |
|---|---|
| **Indexing** | HTTP status, redirects and redirect chains, noindex, canonical (missing or pointing elsewhere) |
| **Titles and descriptions** | Missing, too long, too short, duplicated across pages |
| **Content** | Missing or multiple H1s, thin content (under 200 words) |
| **Links** | Broken internal and external links (404s, 5xx, dead domains), and the pages they appear on |
| **Images** | Images with no alt text |
| **Mobile and tech** | Viewport tag, `lang` attribute, mixed content (http assets on https pages), HTML size, slow server response |
| **Social and schema** | Open Graph tags, JSON-LD structured data |
| **Site level** | **www vs non-www duplication** (both hosts serving the same pages), **http → https redirect**, robots.txt, sitemap reference, duplicate titles, slowest and lowest-scoring pages |

Every issue is labeled **error**, **warning** or **notice**, so you know what to fix first.

### Output

- **Page audit table**: one row per page with its title, description, H1s, canonical, word count, response time, issues and a score.
- **Site summary**: site score, issue counts by priority, every broken link with the pages it appears on, duplicate titles, and the slowest pages.
- **Markdown report**: a ready-to-send audit for clients or your team.

### Example (excerpt)

A 25-page sandbox site:

| Severity | Issue | Pages |
|---|---|---|
| warning | HTTPS page loads http:// resources | 25 |
| warning | Title duplicated on other pages | 2 |
| warning | Missing meta description | 2 |
| notice | No canonical link | 25 |

### Who it's for

- **Agencies and freelancers**: run client audits and win new clients with a free audit.
- **Site owners**: find broken links and quick SEO wins before Google does.
- **Developers**: add an SEO and link check to a deploy pipeline through the API.

### Pricing

**Pay per audited page.** Link checking is included at no extra cost. Set "Max pages" to control spend; the Actor also respects Apify's maximum-charge-per-run setting.

### Good to know

- It's a fast HTTP crawler with no browser, so it audits the HTML your server returns. Content rendered only by JavaScript isn't seen.
- It respects robots.txt by default, crawls politely (5 parallel requests by default) and identifies itself as `SEOAuditBot`.
- Links that block bots (status 401, 403, 429, 999 or Cloudflare 52x, as LinkedIn and X do) are listed separately as "couldn't verify", not counted as broken.
- Please audit sites you own or are authorized to audit.

# Actor input Schema

## `startUrls` (type: `array`):

Homepage (or any page) of the site(s) to audit. The crawler follows internal links on the same domain.

## `maxPages` (type: `integer`):

Maximum pages to crawl and audit (you are charged per audited page).

## `maxDepth` (type: `integer`):

How many clicks away from the start URL to follow.

## `checkLinks` (type: `boolean`):

Check external links (and internal ones beyond the page limit) for 404s and errors. Included in the page price.

## `maxLinkChecks` (type: `integer`):

Cap on extra link checks per run.

## `respectRobotsTxt` (type: `boolean`):

Skip pages the site's robots.txt disallows. Turn off only for sites you own.

## `includeQueryUrls` (type: `boolean`):

Off = '/page?x=1' and '/page' count as the same page (avoids crawling endless filter combinations).

## `concurrency` (type: `integer`):

Parallel requests to the site. Keep low to be polite to small servers.

## Actor input object example

```json
{
  "startUrls": [
    "https://books.toscrape.com/"
  ],
  "maxPages": 100,
  "maxDepth": 10,
  "checkLinks": true,
  "maxLinkChecks": 500,
  "respectRobotsTxt": true,
  "includeQueryUrls": false,
  "concurrency": 5
}
```

# Actor output Schema

## `pages` (type: `string`):

One row per crawled page with SEO fields, issues and a 0-100 score.

## `summary` (type: `string`):

Site score, issues by priority, broken links, duplicate titles, slowest and lowest-scoring pages.

## `report` (type: `string`):

Shareable audit report with a prioritized fix list.

# 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 '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "startUrls": [
        "https://books.toscrape.com/"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("dofunbiz/seo-audit").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);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "startUrls": ["https://books.toscrape.com/"] }

# Run the Actor and wait for it to finish
run = client.actor("dofunbiz/seo-audit").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "startUrls": [
    "https://books.toscrape.com/"
  ]
}' |
apify call dofunbiz/seo-audit --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dofunbiz/seo-audit"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
