## 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

## Bulk Website SEO Auditor & Tech Stack Analyzer

Audit **hundreds or thousands of URLs in minutes**. For every page you get an on-page **SEO audit** (title, meta description, H1, word count, canonical, robots, language, image alt text, mobile-friendly viewport, response time) plus the **tech stack**: CMS, ecommerce platform, JavaScript framework, analytics, CDN and web server.

### Why use this SEO audit tool?

- **Fast and cheap**: plain HTTP requests (no browser), 20 pages in parallel by default.
- **Actionable issues list**: each row says exactly what to fix, such as "Missing meta description", "Title too long (>60)", "Multiple H1 tags" or "Thin content (<300 words)".
- **Tech stack detection** for 35+ technologies: WordPress, WooCommerce, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Magento, BigCommerce, Ghost, Next.js, Nuxt, Gatsby, React, Vue, Angular, Svelte, jQuery, Bootstrap, Tailwind, Google Analytics, Google Tag Manager, Meta Pixel, HubSpot, Hotjar, Cloudflare, Vercel, Netlify, Nginx, Apache, LiteSpeed, PHP and ASP.NET.
- **Never loses a URL**: unreachable pages are returned with an `error` field.

### Use cases

- SEO agencies auditing prospect and client websites in bulk
- Lead generation: find sites on WordPress or Shopify with poor SEO and pitch them
- Competitor and market research on technology usage
- Monitoring your own pages for missing titles, descriptions or noindex tags

# 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": [
        {
            "url": "https://apify.com"
        },
        {
            "url": "https://wordpress.org"
        }
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("harshm07/bulk-seo-auditor-tech-stack").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": [
        { "url": "https://apify.com" },
        { "url": "https://wordpress.org" },
    ] }

# Run the Actor and wait for it to finish
run = client.actor("harshm07/bulk-seo-auditor-tech-stack").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": [
    {
      "url": "https://apify.com"
    },
    {
      "url": "https://wordpress.org"
    }
  ]
}' |
apify call harshm07/bulk-seo-auditor-tech-stack --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,harshm07/bulk-seo-auditor-tech-stack"
        }
    }
}
```

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).
