## 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 Tool & Broken Link Checker - On-Page Score 0-100

Audit single pages or crawl small sites and get, per page, a **0-100 SEO score** and a **prioritised fix list** (high / medium / low).
**$0.009 per page audited.** Link checks are included. Pages that fail (errors, non-HTML, blocked or skipped) are **free**.

### Quick start: example input, output and cost

Bulk on-page SEO audit with 0-100 score and fix list: titles, meta descriptions, H1, canonical, hreflang, schema, alt text, broken links. robots.txt respected.

**Example input**

```json
{
  "startUrls": [
    "https://www.iana.org/help/example-domains"
  ]
}
```

**Cost example:** A 100-page site x $0.009 = **$0.90**.

### What is checked

- **Title** (missing, too long > 60, too short) and **meta description** (missing, > 160)
- **Headings**: missing H1, multiple H1s, H2/H3 counts
- **Indexability**: `noindex`/`nofollow` (meta robots and `X-Robots-Tag`), **canonical** (missing or pointing elsewhere), redirect chains
- **International**: `lang` attribute, `hreflang` alternates
- **Mobile & security**: viewport meta, HTTPS, mixed content (HTTP resources on HTTPS pages)
- **Rich results & sharing**: JSON-LD structured data types (and invalid JSON-LD), Open Graph, Twitter card
- **Content**: word count (thin content), images without `alt`, internal/external link counts, favicon
- **Speed**: server response time for the HTML
- **Broken links** (optional): each internal link (and optionally external) checked once per run; 4xx/5xx/unreachable listed in `brokenLinkList`

### Input

`startUrls` (required), `maxPagesPerSite` (1 = only the listed pages; higher = follow internal links on the same host), `checkLinks`, `checkExternalLinks`, `maxLinksCheckedPerPage`.

### Output

One item per audited page with all fields above, `issues[]` (code, severity, message) and `seoScore`. Use the **Issues** view for a flat fix list. Failed URLs and reasons are in **ERRORS**; totals in **SUMMARY**.

### Limits

- It reads the HTML the server sends (no browser), so text, links or markup added later by JavaScript are not seen.
- It checks on-page signals only. It has no backlink, keyword ranking or traffic data.
- Response time is measured from Apify's servers and is a rough guide, not a Core Web Vitals score.

### Responsible crawling

We follow each site's **robots.txt** (disallowed pages and links are skipped and not charged), send at most about one request per second per site, use an honest User-Agent (`SEOAuditOnPage/1.0`), and never log in or bypass bot protection. Audit sites you own or are allowed to analyse.

### Pricing

| Event | Price |
|---|---|
| Page audited (HTML fetched and analysed) | $0.009 |

A 200-page site audit with link checks costs $1.80. No start fee.

# Actor input Schema

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

Pages to audit (up to 500). With 'Max pages per site' above 1, internal links of the same host are followed. Only public pages; robots.txt is respected.

## `maxPagesPerSite` (type: `integer`):

1 = audit only the listed pages. Higher = crawl internal links (same host, breadth-first).

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

Request each internal link (HEAD) and report 4xx/5xx as broken links. Included in the page price.

## `checkExternalLinks` (type: `boolean`):

Also check links to other sites (each site's robots.txt is respected).

## `maxLinksCheckedPerPage` (type: `integer`):

Each link is checked once per run, even if many pages link to it.

## Actor input object example

```json
{
  "startUrls": [
    "https://www.iana.org/help/example-domains"
  ],
  "maxPagesPerSite": 1,
  "checkLinks": false,
  "checkExternalLinks": false,
  "maxLinksCheckedPerPage": 100
}
```

# Actor output Schema

## `results` (type: `string`):

## `errors` (type: `string`):

Inputs that could not be processed, with the reason

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

# 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://www.iana.org/help/example-domains"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("digivibetech/seo-audit-onpage").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://www.iana.org/help/example-domains"] }

# Run the Actor and wait for it to finish
run = client.actor("digivibetech/seo-audit-onpage").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://www.iana.org/help/example-domains"
  ]
}' |
apify call digivibetech/seo-audit-onpage --silent --output-dataset

```

## MCP server setup

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

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).
