Question 1

What is a web performance diagnostic?

Accepted Answer

A web performance diagnostic analyzes your website's speed, Core Web Vitals, and technical health. It identifies what's slowing your site down and tells you exactly what to fix first — in plain English, not technical jargon.

Question 2

What are Core Web Vitals?

Accepted Answer

Core Web Vitals are Google's three key measures of user experience: Largest Contentful Paint (how fast your main content loads), Cumulative Layout Shift (how stable your page is visually), and Interaction to Next Paint (how quickly your page responds to clicks). Poor Core Web Vitals hurt both your search rankings and your conversion rate.

Question 3

How long does the diagnostic take?

Accepted Answer

The diagnostic runs in 30 to 60 seconds. You get a full report immediately — no waiting, no signup, no payment required.

Question 4

Is this diagnostic really free?

Accepted Answer

Yes. No signup, no credit card, no catch. Enter your URL and email and get your full report instantly. We send a copy to your email so you can refer back to it.

Question 5

What's the difference between mobile and desktop performance scores?

Accepted Answer

Mobile and desktop scores often differ significantly because mobile devices have slower processors and connections. A site can score 96 on desktop and 67 on mobile. Since over 60% of web traffic is mobile, your mobile score is the one that matters most for conversions.

Question 6

What causes a slow website?

Accepted Answer

The most common causes are render-blocking JavaScript, unoptimized images, poor caching configuration, and caching plugin conflicts (such as WP Rocket and EverCache running simultaneously). Our diagnostic identifies which of these is affecting your site and ranks them by impact.

Question 7

What should I do after getting my diagnostic report?

Accepted Answer

Fix the highest-impact issue first. The report prioritizes your top three issues in order. If you need help implementing the fixes, FrohnenGTM offers fractional GTM and technical implementation support — click 'Want us to fix this for you?' at the bottom of your report.

Question 8

Will fixing my Core Web Vitals improve my Google rankings?

Accepted Answer

Yes. Google uses Core Web Vitals as a ranking factor. Improving your LCP from 5 seconds to under 2.5 seconds can meaningfully improve your search visibility, especially on mobile. It also directly improves conversion rates — sites with LCP under 2.5 seconds convert 24% better than slower sites.
