30-Second Summary
No one waits more than 3 seconds. We analyze the impact of Core Web Vitals on your monthly revenue.
Amazon calculated that for every 100ms of delay, they lose 1% of sales. For an SME, if your site takes more than 3 seconds to load, you will lose 53% of your mobile visits.
What are Core Web Vitals?
They are Google's official metrics for measuring user experience quality. If you fail here, Google hides you in the results.

The 5 Common Culprits of Slowness
- 1. Giant Images: Uploading photos directly from the camera (5MB) instead of optimizing them in WebP format (50KB).
- 2. Excess Plugins: Installing a plugin for every small function (WhatsApp, Form, Slider) adds tons of garbage code.
- 3. Cheap Hosting: Shared servers for $2 USD group thousands of sites, stealing resources from each other.
- 4. Render-blocking JavaScript: Code that stops visual loading until it is completely downloaded.
- 5. Lack of Cache: Not saving static versions of your site to serve them fast.
