## 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

## PageSpeed Lighthouse Audit, Core Web Vitals & Technical SEO API ($1.00 / 1,000 URLs)

Audit thousands of websites or prospect domains in bulk for **response time (TTFB), technical SEO score (0–100), meta title/description optimization, H1/H2 structure, missing image `alt` attributes, Schema.org JSON-LD, `robots.txt`, and `sitemap.xml`** at **just $1.00 per 1,000 URLs** — **100% browserless in 256 MB RAM**.

Built for **SEO Agencies**, **Web Design & CRO Agencies**, **Clay.com Cold Email Personalization**, **n8n**, **Make**, and **MCP AI Agents**.

***

### Why SEO Agencies & Outbound Teams Use This API

1. **Instant Cold-Email Personalization (`seoIssues`)**: Automatically generates concrete technical flaws for every prospect website (e.g., *"Missing meta description"*, *"Multiple H1 tags"*, *"14 images missing alt attributes"*, *"No Schema.org JSON-LD found"*, *"Slow TTFB > 2500ms"*).
2. **Sub-Second Chrome-Fingerprinted Execution**: Uses `impit` (`Chrome` TLS fingerprint) in `256 MB RAM` without getting blocked by Cloudflare or waiting 25 seconds per URL for headless Chromium.

***

### Input Example

```json
{
  "urls": [
    "https://linear.app",
    "https://allbirds.com"
  ],
  "checkRobotsAndSitemap": true,
  "includeMcpMarkdown": true
}
```

# 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

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({

## CLI example

```bash
echo '{
  "urls": [
    "https://linear.app",
    "https://allbirds.com"
  ]
}' |
apify call ramirez911/pagespeed-lighthouse-seo-audit-api --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,ramirez911/pagespeed-lighthouse-seo-audit-api"
        }
    }
}
```

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).
