Bulk PageSpeed Insights: Core Web Vitals and Lighthouse

⚡ What is Bulk PageSpeed Insights?

PageSpeed checks for load time across a long list of pages. Each entry joins the Lighthouse marks, detailed timings and the Core Web Vitals real Chrome visitors experienced, along with the biggest savings Lighthouse found.

• SEO audits: measure every important page of a client site in one run instead of one by one in the browser
• Monitoring: schedule a weekly run and track Core Web Vitals after every release
• Competitor benchmarks: compare your landing pages with your rivals' on mobile and desktop
• Agency reports: export scores and savings to Google Sheets or Looker Studio

✨ Why use this Actor?

• ✅ Official Google data: the same API behind pagespeed.web.dev, no proxy needed
• ✅ Lab and field in one row: Lighthouse timings next to real-user Chrome UX Report data; fieldScope says whether it describes the URL or its origin
• ✅ Mobile, desktop or both: strategy: both gives two rows per URL
• ✅ What to fix first: the largest Lighthouse opportunities with their savings in milliseconds
• ✅ Retries: backoff on 429 and 5xx; API errors are not charged

📦 What data can you get with Bulk PageSpeed Insights?

🏎️ Performance score	♿ Accessibility score	✅ Practices score
🔍 SEO score	🧪 Lab FCP, LCP, TBT, CLS	⏱️ Speed Index, TTI, TTFB
👥 Real-user LCP, INP, CLS, FCP, TTFB	🚦 Category per metric	💡 Top opportunities and savings

Real-user data exists only for pages and origins with enough Chrome traffic; otherwise field is null and the lab metrics still come back.

            "command": "npx",
            "args": [
                "-y",

            ],
            "env": {
                "APIFY_TOKEN": "<your Apify API token>"
            }
        }
    }
}

Then ask: "Check the mobile PageSpeed scores and Core Web Vitals of these 10 landing pages and tell me which ones fail LCP."

Run it from your code

Python (pip install apify-client):

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("bepolabs/pagespeed").call(run_input={"urls":["https://example.com/"]})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

JavaScript (npm install apify-client):

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('bepolabs/pagespeed').call({"urls":["https://example.com/"]});
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

No-code integrations

Send results to Google Sheets, Slack, Airtable, HubSpot, Make, Zapier, n8n and more from the Integrations tab, start runs on a schedule, or trigger your own endpoint with a webhook when a run finishes. The Apify API gives you full control over runs and datasets.

❓ FAQ

Why do I need my own API key?

Google's PageSpeed Insights API asks for a key; it is free and its quota is yours, so your audits never share a limit with other users.

Why is field null for my page?

The Chrome UX Report has real-user data only for pages and origins with enough traffic. The lab metrics and scores are still measured.

Are the scores the same as on pagespeed.web.dev?

Both rely on one API and Lighthouse version, so numbers match within Lighthouse's normal run-to-run variance.

Is it legal to use Bulk PageSpeed Insights?

The Actor calls the public PageSpeed Insights API with your own key, under Google's APIs Terms of Service. It measures only the URLs you give it, as a browser visit would.
