## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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

## On-Page SEO Audit Crawler

Crawls a website you own or manage and checks every page for common on-page SEO problems. You get one row per page with the measured values and a list of issues, ready to export as JSON, CSV or Excel.

### What it checks

- **Title**: missing, too short (<15) or too long (>60 characters)
- **Meta description**: missing, too short (<50) or too long (>160)
- **H1**: missing or more than one; H2/H3 counts
- **Canonical URL, `lang`, viewport, robots meta / noindex**
- **Open Graph and Twitter card** tags, hreflang count, JSON-LD blocks
- **Images** without an `alt` attribute
- **Thin content** (under 150 visible words)
- **HTTP errors** (404, 5xx, fetch failures)
- **Duplicates** across the crawled pages: same title, same meta description
- Number of internal links pointing to each page

Issues are labelled `error:`, `warning:` or `info:`, for example `warning:title-too-long`.

### Input

| Field | Meaning |
|---|---|
| startUrls | Where to start. Only the same site (host) is crawled. |
| maxPages / maxDepth | Crawl size limits (default 50 pages, depth 3). |
| onlyPagesWithIssues | Save only the pages that have problems. |
| respectRobotsTxt | On by default. |
| urlExcludes | Skip internal URLs containing these strings. |

### Output example

```json
{"url": "https://example.com/", "status": 200, "title": "Example Domain", "titleLength": 14,
 "metaDescription": "", "h1Count": 1, "wordCount": 28, "imagesMissingAlt": 0,
 "issues": ["error:missing-meta-description", "warning:title-too-short", "info:thin-content"], "issueCount": 3}
```

### Notes

- Fetches pages with plain HTTP: it reads the HTML the server returns and does not run JavaScript, so pages rendered only in the browser will look empty.
- Use it only on sites you own or are allowed to crawl. Keep concurrency low on small sites.
- The thresholds are common rules of thumb, not guarantees about rankings.

# Actor input Schema

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

Pages to start from. Only pages on the same site (host) as a start URL are crawled; use sites you own or are allowed to crawl.

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

Maximum number of pages to fetch and audit.

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

How many clicks away from the start URL to crawl. 0 audits only the start pages.

## `onlyPagesWithIssues` (type: `boolean`):

Save only pages that have at least one issue.

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

Skip pages disallowed by robots.txt.

## `urlExcludes` (type: `array`):

Internal links containing any of these strings (case-insensitive) are not crawled, e.g. /tag/ or ?replytocom.

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

Simultaneous page fetches. Keep low for small sites.

## `timeoutSeconds` (type: `integer`):

Per-request timeout.

## Actor input object example

```json

# 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://example.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("forbearing_guanaco/seo-audit-page-checker").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://example.com"] }

# Run the Actor and wait for it to finish
run = client.actor("forbearing_guanaco/seo-audit-page-checker").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://example.com"
  ]
}' |
apify call forbearing_guanaco/seo-audit-page-checker --silent --output-dataset

```

## MCP server setup

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

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).
