PageSpeed Insights & Core Web Vitals Bulk Audit

What does PageSpeed Insights & Core Web Vitals Bulk Audit do?

This Actor checks Lighthouse scores and real-user Core Web Vitals for hundreds of URLs in one run. It uses the official Google PageSpeed Insights API, so results are identical to what you see on pagespeed.web.dev, just in bulk, as a table and via API.

For every URL and device (mobile and/or desktop) you get:

• Performance, Accessibility, Best Practices and SEO scores (0–100)
• Core Web Vitals from the Chrome UX Report (CrUX): LCP, INP, CLS, FCP and TTFB at the 75th percentile, plus a clear PASSED / FAILED assessment
• Lab metrics from Lighthouse (LCP, FCP, TBT, CLS, Speed Index)
• The top 5 optimization opportunities ranked by estimated time savings

No proxies, no browser and no scraping are involved, so runs are fast and reliable.

Why use this PageSpeed Insights bulk checker?

• Audit a whole site or a client portfolio at once instead of pasting URLs into pagespeed.web.dev one by one
• Monitor Core Web Vitals over time: schedule the Actor weekly and compare datasets
• Find the pages that fail Google's Core Web Vitals before they cost you rankings
• SEO agencies: export a client-ready table to Google Sheets, Excel or CSV
• Developers: call it from the Apify API, Make, Zapier or n8n after every deploy
• Pay only for successful audits: URLs that Google cannot test are reported with an error and are not charged

What data does the PageSpeed audit return?

Field	Description
performanceScore	Lighthouse performance score (0–100)

fieldLcpMs, fieldInpMs, fieldCls	Real-user Core Web Vitals (p75)
fieldDataScope	url for page-level data, origin when only site-wide data exists
labLcpMs, labTbtMs, labCls	Lighthouse lab metrics
seoScore, accessibilityScore, bestPracticesScore	Other Lighthouse category scores
topOpportunities	Up to 5 failed audits with estimated savings in ms
error	Reason if the URL could not be audited

How to check PageSpeed for many URLs

1. Click Try for free.
2. Paste your URLs into the URLs field, one per line.
3. Choose Mobile, Desktop or both.
4. Click Start and wait. Each audit takes 10–30 seconds, five run in parallel.
5. Download the results as JSON, CSV, Excel or HTML, or open them in the table view.

How much does a PageSpeed audit cost?

This Actor uses pay per event: you pay a fixed price per successful audit (one URL on one device), and platform usage is included. Failed audits are free. The current price is shown in the Pricing tab. Apify's free plan includes monthly credits, enough to try the Actor on your own site.

FAQ

How fast is it? Can I audit thousands of URLs?

Google limits each API key to 30 audits per minute. The Actor waits and retries automatically, so large lists finish, just slower. To speed up big jobs, add your own free Google API key in the Advanced input section; your runs then use your own quota.

Why is coreWebVitals empty for some pages?

Google only publishes real-user data for pages and sites with enough Chrome traffic. Small sites often have no CrUX data. When page-level data is missing, the Actor falls back to site-wide (origin) data and sets fieldDataScope to origin.

Why do my scores differ slightly between runs?

Lighthouse lab scores vary by a few points from run to run. This is normal and also happens on pagespeed.web.dev. Real-user Core Web Vitals are a 28-day average and stay stable.

Can I audit pages behind a login?

No. Google's servers must be able to reach the URL publicly.

Something does not work

Please open an issue in the Issues tab with the URL and the run ID. You can also start the Actor programmatically from the API tab.
