Your site speed is costing you sales: a practical fix guide

Every second of delay cuts conversion by up to 7%. How to measure speed correctly — and what's worth fixing first.

Your site speed is costing you sales: a practical fix guide

Arab customers mostly browse on mobile over average networks. A site that opens in 6 seconds isn't 'a bit slow' — it effectively never opens, because the visitor went back to search results before seeing it.

Measure correctly first

Use PageSpeed Insights and read the real-user data, not just the lab score. Focus on three numbers: LCP under 2.5s, INP under 200ms, CLS under 0.1.

What to fix first

  • Images: WebP conversion and correct sizing usually solves half the problem
  • Leftover tracking scripts: every old pixel still firing has a price
  • Cheap hosting: no optimization saves a 600ms+ server response
  • Fonts: load only two weights per family and use font-display: swap
In one store we rebuilt, load time dropped from 7s to 2.1s — conversion rose 38% with the same traffic and the same products.
QUICK TEST Open your store on mobile data (not Wi-Fi) in incognito. If the key content isn't visible within 3 seconds, you're losing sales right now.
