The verdict in three sentences
If your site loads in more than 4 seconds, isn't responsive, or is over 5 years old, it costs you customers every single day. A redesign isn't a cosmetic expense: it's an investment that often returns +20 to +40 % more leads. The real risk isn't the cost of the redesign — it's the cost of doing nothing.
The 6 data-backed signals you need a new site
An ageing site sends measurable signals. Here are the alert thresholds to compare against your own data (Google Analytics, PageSpeed Insights).
| Signal | Alert threshold | Business impact |
|---|---|---|
| Bounce rate | > 70 % | Visitors leaving without acting |
| Load time | > 4 s | -7 % conversion per second |
| Unmanaged mobile traffic | non-responsive site | 60 % of traffic lost |
| No HTTPS | no padlock | -15 % trust, SEO penalty |
| Design age | > 5 years | Dated brand image |
| Lighthouse score | < 50/100 | Google ranking penalty |
If you tick three boxes or more, a redesign is no longer optional. Every month of delay turns into leads gone to a better-equipped competitor.
Redesign or rebuild: what to choose and at what price
Not all redesigns are equal. A cosmetic refresh differs from a full rebuild, and the budget can triple between them.
| Type of work | Timeline | Indicative 2026 price (FCFA) | Expected gain |
|---|---|---|---|
| Visual refresh | 5-7 days | 250,000 - 500,000 | +10-15 % engagement |
| Responsive + perf redesign | 10-15 days | 500,000 - 900,000 | +20-30 % leads |
| Full rebuild | 15-25 days | 900,000 - 1,500,000 | +30-40 % leads |
| Tech migration (Next.js) | 20-30 days | 1,200,000 - 2,500,000 | LCP cut by 3x |
These figures are a 2026 order of magnitude for the Senegalese and West African market. A high-performing showcase site usually pays for itself with 2 to 5 new customers depending on your average deal size.
Mini case study
Awa runs a home-decor shop in Dakar. Her old site took 5.2 seconds to load and wasn't responsive. With a 78 % bounce rate and 1,200 visitors/month, she got just 6 quote requests monthly.
After a responsive redesign at 750,000 FCFA, load time drops to 1.9 s, bounce to 48 %, and requests rise to 17 per month. At an average deal of 120,000 FCFA and a 30 % closing rate, that's roughly +396,000 FCFA in monthly revenue — the redesign pays for itself in under two months.

FAQ
How long does a showcase-site redesign take?
Between 5 and 25 days depending on scope. A visual refresh takes a week; a full rebuild with new content runs 15 to 25 working days.
Will I lose my Google rankings?
No, if the migration is done cleanly with 301 redirects and preserved URL structure. A well-run redesign actually improves SEO thanks to better Core Web Vitals.
How much does a redesign cost in Senegal in 2026?
From 250,000 FCFA for a refresh to 1,500,000 FCFA for a full rebuild. Migrating to a modern stack like Next.js can reach 2,500,000 FCFA.
How do I know if my site is really too slow?
Test it on PageSpeed Insights: a mobile score below 50 and an LCP above 4 seconds confirm the problem. Run the test on 3G to reflect your visitors' reality.
Does a redesign guarantee more customers?
No serious agency guarantees a number, but experience shows a typical 20 to 40 % lead gain when the original site was slow and non-responsive.
