A one-off scan tells you where you stand today. A free account tells you when it changes — and what changed.
Why page weight matters
Page weight — the total size of all files a browser must download to display your page — directly affects how fast your site loads. Google uses Core Web Vitals as a ranking signal for mobile search. Images typically account for 50–80% of total page weight on most sites, making them the highest-impact place to start.
Slow sites lose visitors before the page finishes loading — the longer a mobile page takes, the more likely a visitor bounces before it even renders.
Common questions
How does PageWeight work?
We send your URL to the Google PageSpeed Insights API and present the results in plain English. PageWeight is powered by Google’s Lighthouse engine — the same technology behind the Performance tab in Chrome DevTools.
Is it free?
Scanning is free and needs no account — just enter a URL. If you want to track a site over time, a free account gives you 3 URLs, daily checks and 30 days of score history. Paid plans add more URLs, hourly checks and longer history — see pricing. PageWeight is built by Picqlo, an image optimization service for WordPress and beyond.
Why does it default to mobile?
Google uses mobile-first indexing — your search ranking is based on how the mobile version of your site performs. Mobile is the default because it’s the most important measure for SEO. You can switch to Desktop using the toggle that appears in your results.
What does the performance score mean?
Scores of 90–100 are considered fast, 50–89 need improvement, and below 50 are poor. The score is a weighted combination of Core Web Vitals and other performance metrics, calculated by Google’s Lighthouse engine.
How accurate are the results?
Results come from the same Lighthouse engine used by Google Search Console. Because the analysis runs from a Google data center rather than a visitor’s device, scores may differ slightly from real-world experience — location, device speed, and network conditions all affect actual performance.
