Prečo na tom záleží

53% of mobile users abandon a page that takes longer than 3 seconds to load. Google uses Core Web Vitals as a ranking factor — a slow store means lower search positions, fewer visitors, and fewer sales. The average store sees a 15–30% conversion rate uplift after speed optimization. The speed test shows you exactly what's costing you sales and how to fix it fast.

Často kladené otázky

How long does the speed test take?
The test takes 30–60 seconds. We analyze your homepage using the Google PageSpeed Insights API plus our own checks. Results arrive immediately — nothing to install, no accounts to create.
Does it work with PrestaShop?
Yes. The speed test works with PrestaShop (all versions), WooCommerce, Magento, Shopify, OpenCart and custom builds. We detect the platform automatically and tailor recommendations to that system.
What are Core Web Vitals?
Core Web Vitals are three Google metrics: LCP (Largest Contentful Paint — how fast the main content loads), CLS (Cumulative Layout Shift — how much the layout shifts during load), and INP (Interaction to Next Paint — how quickly the page responds to input). Since 2021 they're an official Google search ranking factor.
How do I improve my score?
Our report includes concrete recommendations for every issue — what to fix, how to do it, and the expected impact. For PrestaShop stores we offer modules that fix most issues automatically. For other platforms we offer expert consulting.
Is it free?
Yes, 100% free. No signup, no credit card, no hidden limits. Run as many tests as you want.
What data do you store?
Only publicly available information — URL, HTTP headers, aggregated scores. No passwords, no personal data, no access to non-public content. Data is automatically deleted after 90 days.
