How to Set Up Automated PageSpeed Monitoring for Multiple Sites

The Problem: Manual Testing Doesn't Scale You manage 10 client sites. Each has 5 key pages. You want to test both mobile and desktop. That's 100 tests — every time you want a snapshot of your portfolio's performance. Running those tests manually in PageSpeed Insights takes about 2 minutes each. That's over 3 hours of tab-switching, waiting, and copy-pasting numbers into a spreadsheet. And by the time you finish the last site, the first site's results are already hours old. This is why automated monitoring exists. Set it up once, and every test runs itself. What Automated PageSpeed Monitoring Should Do Before choosing a tool or approach, define what you need: Must-Have Features Scheduled testing — Tests run automatically at configured intervals (daily, hourly, etc.) Multiple sites — Manage all your sites from one place Mobile and desktop — Test both strategies for every page Historical data — Store results over time for trend analysis Alerting — Get notified when performance degrades be
