What is it

Our Performance Testing service uses k6 browser automation to measure your WordPress site’s Core Web Vitals (CWV) — the critical speed and user experience metrics that Google and your visitors care about most. We run real browser-based tests to give you accurate insights into how fast and smooth your site feels across key user interactions.

What We Can Test

  • Homepage speed and responsiveness

  • Product and service page performance

  • Checkout flows and forms

  • Navigation speed across your site

  • Mobile and desktop performance differences

  • CWV metrics: Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and more

We can customize testing to focus on your site’s most important pages and flows.

Why Your Business Needs It

Slow-loading websites hurt conversions, lower SEO rankings, and frustrate your visitors. Even small performance issues can cause lost sales, reduced engagement, and higher bounce rates.

Core Web Vitals are now a major ranking factor in Google search — making performance not just a user experience issue but a business-critical priority.

With QAWP’s performance testing, you’ll know exactly where your site stands and what areas need improvement — before your customers (or Google) notice problems.

How It Works

  1. Setup: We configure automated k6 browser tests targeting your live site or staging environment.

  2. Execution: Tests simulate real user interactions, measuring actual Core Web Vitals in the browser.

  3. Results: You get clear reports showing your CWV scores, bottlenecks, and optimization opportunities.

  4. Ongoing Monitoring: Optionally, we can schedule recurring tests to catch performance regressions over time.

Everything runs seamlessly through your existing QAWP dashboard — no technical setup needed on your side.
