The verdict in three sentences
A redesign is not a gut call but a response to metrics that bleed: conversion, bounce, speed, cart abandonment. The real cost is not the redesign, it is the sales lost every month by a slow, unreadable-on-mobile store. In 2026, a well-targeted redesign typically pays for itself in 2 to 4 months when these signals are in the red.
The 8 signs it is time to act
Here are the alert thresholds. If three or more are crossed, a redesign is no longer a cosmetic choice but an economic decision.
| Signal | 2026 alert threshold | What it costs |
|---|---|---|
| Mobile conversion | < 1% | Wasted paid traffic |
| Bounce rate | > 65% | Visitors lost in 5s |
| LCP (speed) | > 4s | -20% conversions |
| Cart abandonment | > 80% | Unfinished orders |
| No MoMo/Wave option | 0 local option | Up to 40% of buyers blocked |
| Checkout steps | > 5 | +10% abandonment per step |
| Mobile share of traffic | > 70% but desktop-only site | Wrong experience |
| Pages without reviews or HD photos | most of catalogue | Trust collapse |
In the Accra market as in Dakar, over 70% of traffic is mobile and often on 3G. A 4.5-second LCP loses one in two visitors before the product even appears.
The before/after table that justifies the budget
A redesign is judged on the revenue delta, not the look. Here is a typical scenario for a store doing 4,000,000 FCFA in monthly sales.
| Metric | Before | After redesign | Effect |
|---|---|---|---|
| Mobile conversion | 0.8% | 2.1% | x2.6 |
| LCP | 4.6s | 1.7s | -63% |
| Cart abandonment | 82% | 61% | -21 pts |
| Average order | 18,000 FCFA | 21,000 FCFA | +17% |
| Monthly revenue | 4,000,000 FCFA | 9,500,000 FCFA | +5,500,000 FCFA |
For a redesign priced at 1,500,000 FCFA, a 5,500,000 FCFA monthly gain means payback in under 3 weeks of extra sales. Even with assumptions twice as conservative, payback holds within 2 to 4 months.

Mini case study
Kofi, who runs an accessories store in Accra, hesitated to invest. His site loaded in 5.2 seconds, had no Mobile Money option, and a 6-step checkout. Diagnosis: 0.7% mobile conversion, 84% cart abandonment. After a 1,400,000 FCFA redesign — optimised speed, MoMo integrated, 3-step checkout — his mobile conversion rose to 1.9% and monthly revenue climbed from 3,200,000 to 6,800,000 FCFA. Payback: 4 weeks.
FAQ
When does a redesign become profitable? As soon as three signals are red. If your mobile conversion is under 1% and cart abandonment above 80%, every month of delay costs more than the redesign itself, which usually pays back in 2 to 4 months.
Rebuild everything or just optimise? It depends on the technical foundation. If the architecture holds, you optimise speed, checkout and payments for 400,000 to 900,000 FCFA. If the foundation is obsolete, a full redesign at 1,500,000-3,000,000 FCFA is more profitable long term.
Why is the absence of Mobile Money so serious? Because in Ghana, Benin or Senegal, up to 40% of buyers pay via MoMo, Wave or Orange Money. Without a local option, you lose those orders at the final click, after paying for the traffic.
How long does a redesign take? A targeted optimisation takes 1 to 2 weeks. A full redesign with new design, payment integration and product migration takes 3 to 6 weeks depending on catalogue size.
How do I measure that my store is too slow? An LCP above 4 seconds on mobile 3G is a critical threshold: each extra second drops conversion by roughly 20%. Test on a real phone on mobile data, not on fibre Wi-Fi.
