# Check Core Web Vitals and PageSpeed on mobile and desktop

**Use case:** 

Runs a Google PageSpeed check on each page you list and puts the mobile and desktop results side by side in one row, with the performance score, Core Web Vitals and what to fix first. No API key needed to start, or add your own free Google key for a lower price per audit. Export to Excel, CSV or JSON. You pay per successful audit, plus a tiny start fee per run.

## About this Actor

This example demonstrates how to use [PageSpeed and Core Web Vitals Auditor](https://apify.com/vizellie/pagespeed-auditor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/vizellie/pagespeed-auditor.md) to learn more, explore other use cases, and run it yourself.


## 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/vizellie/pagespeed-auditor.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`).
