Visitors expect pages to load quickly. When they don’t, people leave, and they take their custom with them. But how do you know if your site is quietly costing you sales?

Here are five warning signs that it’s time to optimise, with fixes you can start this week.

Speed isn’t just a feature; it’s the first impression you give every visitor.

1. High bounce rates

A slow first paint frustrates visitors. Tools like Lighthouse show which scripts block the page from rendering.

2. Mobile users complain

Uncompressed images and bulky CSS punish people on mobile data. Serve WebP images and design for phones first.

3. Your search rankings have stalled

Google’s Core Web Vitals reward speed. Poor LCP or CLS scores drag rankings down.

4. People abandon the checkout

Every extra second at the payment step loses sales. Cut back the third-party scripts on the pages that take money.

5. Server costs keep rising

Inefficient code needs more computing power. Profiling database queries and adding caching can cut your hosting bill.

Website performance is now table stakes. Fast sites convert more visitors, rank higher and cost less to run.
