Not the flashiest design — the one that loads fast, works on a phone, and turns visitors into enquiries.
A slow site loses visitors before they've seen anything — speed is a conversion factor, not a technicality.
Most visitors will land on a phone. If the mobile experience is an afterthought, most of your traffic gets a worse version of the site.
Every page should make it obvious how to get in touch — a buried contact form is a lost enquiry.
Titles, descriptions, and structure set up properly from launch, not bolted on afterward.
A visually striking site that's slow, hard to navigate, or breaks on mobile does more harm than a plain, functional one.
A homepage that looks good but doesn't say clearly, in the first few seconds, what the business does and for whom.
A site built once and never revisited, while the business and its offering move on without it.
