A fast website isn't a nice-to-have. It's a revenue lever. Studies consistently show that conversions drop as load time climbs, so speeding up your site directly increases leads and sales.

When a page is slow, visitors leave before it finishes loading. That lost attention compounds: fewer people see your offer, fewer fill out your form, and fewer call. Even a one-second delay can move conversion rates noticeably.

What slows sites down

Oversized images

Unoptimized images are the most common cause of slow pages. Serving correctly sized, modern formats fixes most of the problem.

Too many third-party scripts

Analytics, chat widgets, and ad pixels each add weight. Audit them and remove what you don't use.

Core Web Vitals

Google's Core Web Vitals measure loading, interactivity, and visual stability. They influence rankings and closely track real user experience, so improving them helps twice.
