5 Reasons why your website is slow (and how it costs you sales)

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.
