Why the slow site quietly kills your sales (and how to score 90+)
Slow site is the most expensive problem you can't see. No one will complain to you — the visitor simply pushes back and goes to competition. Each extra second of loading costs up to 20% of visitorsand over half of mobile users leave the page that is loaded for more than three seconds.
Double damage: customers + Google
The speed does not only affect customer patience. Google openly says it as a rating factor (Core Web Vitals): two similar sites, faster goes above. It means that the slow site loses twice – and the visitors it has received, and those that it will never get due to a worse position.

Five most common (in frequency order)
- Unoptimised images — a photo of 4 MB where 80 KB of WebP is needed. Blame number 1 in 8 of 10 sites.
- Cheap, crowded hosting - server responds slowly before anything starts to load.
- Too many add-ons/scripts — each plugin, widget and "only one more tracking tool" slows down.
- No Cache — The site is built for each visitor from the beginning instead of serving a finished copy.
- Effects on themes - a topic that can do anything, so it's slow.
What can you do for yourself and what can you leave to us?
By yourself: reduce and convert images into webP before posting, delete plugins you do not use. Other (cashing, code, server, Core Web Vitals) is a job for a hour or two of professional work.
