# Check Core Web Vitals for a List of Websites (Mobile)

**Use case:** 

Check Core Web Vitals and Lighthouse scores for several websites at once on mobile: performance, accessibility, best practices and SEO scores, plus LCP, CLS, TBT, FCP and Speed Index, one row per site. Lighthouse runs in the Actor itself, so no PageSpeed Insights API key or Google quota is needed. Replace the three example sites with your own pages or competitors.

## Input

```json
{
  "urls": [
    "https://www.python.org",
    "https://crawlee.dev",
    "https://www.djangoproject.com"
  ],
  "strategy": "mobile",
  "categories": [
    "performance",
    "accessibility",
    "best-practices",
    "seo"
  ],
  "includeAudits": false,
  "maxConcurrency": 1,
  "timeoutSecsPerUrl": 90
}
```

## Output

```json
{
  "url": {
    "label": "URL",
    "format": "link"
  },
  "strategy": {
    "label": "Device",
    "format": "text"
  },
  "scores": {
    "label": "Scores"
  },
  "metrics": {
    "label": "Metrics"
  },
  "finalUrl": {
    "label": "Final URL",
    "format": "link"
  },
  "engine": {
    "label": "Engine",
    "format": "text"
  },
  "error": {
    "label": "Error",
    "format": "text"
  }
}
```

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

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 full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/charlesmarkette/pagespeed-lighthouse-audit-core-web-vitals.md

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`).
