It is difficult to read or navigate on a phone. Most Kenyan traffic is mobile, so a site that only behaves on desktop is losing the majority of its visitors.
It loads slowly on a normal mobile connection. Visitors rarely wait, and slow pages also weaken search performance.
The content no longer matches what you actually sell. Old services, old pricing or old contact details create doubt.
There is no clear next step. If a visitor cannot immediately see how to enquire, the site is a brochure rather than a business tool.
You cannot update it yourself. If every small text change requires an external request, updates stop happening.
