The verdict in three sentences
A Dakar fast-food chain (QSR) paying for Google Ads to a slow landing page (LCP > 5 s) burns its budget: 60 % of mobile traffic leaves before seeing the offer. A CRO redesign with Wave payment, INP under 200 ms and CTA A/B testing lifts mobile conversion from 0.8 % to 3.9 %, on queries like "order pizza Dakar" (650 searches/month). Budget 150 to 300K FCFA, 5 to 7 days, and a Core Web Vitals audit at 60-100K FCFA.
CRO starts with speed
A QSR landing page lives or dies on mobile within seconds. If LCP exceeds 5 s and INP (tap responsiveness) drags, the customer taps elsewhere. Conversion rate optimization (CRO) therefore starts with Core Web Vitals, then works the journey: one goal per page, a visible CTA, Wave payment in two taps.
| Metric | Before redesign | After 2026 redesign | Target |
|---|---|---|---|
| Mobile LCP | 5.2 s | 1.8 s | < 2.5 s |
| INP (responsiveness) | 410 ms | 150 ms | < 200 ms |
| Mobile conversion | 0.8 % | 3.9 % | - |
| Mobile traffic lost | 60 % | < 20 % | - |
| Payment | external redirect | Wave in 2 taps | - |
| CTA uplift (A/B test) | - | +22 % | - |
The CTA A/B test (text, color, position) alone adds +22 % once the technical base is sound. But testing a CTA on a 5 s LCP page is pointless: fix speed first.
CRO budget and impact on acquisition cost
| Item | FCFA range | Lead time |
|---|---|---|
| CRO landing page redesign | 150,000 - 300,000 | 5-7 days |
| Core Web Vitals audit | 60,000 - 100,000 | 2 days |
| Wave payment integration | base included | 1 day |
| CTA A/B test setup | +50,000 | 2 days |
| Google Ads / conversion tracking | included | 1 day |
| Monthly maintenance / iteration | 25,000 / month | - |
The business impact is direct: if conversion goes from 0.8 % to 3.9 %, the cost per order from Google Ads drops by ~5x for the same ad budget. It's often the most profitable redesign in the catalog.
Mini case study
A Dakar pizza chain spent 200,000 FCFA/month on Google Ads to a landing with 5.2 s LCP, converting 0.8 %. On ~2,500 monthly visits that was 20 orders. After a 260,000 FCFA CRO redesign delivered in 6 days (Wave, INP 150 ms, A/B test): conversion 3.9 %, i.e. ~97 orders/month for the same traffic. At a 7,000 FCFA average basket, Ads-driven revenue goes from 140,000 to 679,000 FCFA/month. The redesign pays back in under a month, and every ad franc works five times harder.

FAQ
How much does a fast-food landing page redesign in Dakar cost in 2026?
Between 150,000 and 300,000 FCFA for an optimized CRO landing, plus 60,000 to 100,000 FCFA for the Core Web Vitals audit if needed. Maintenance runs around 25,000 FCFA/month.
How much can conversion actually rise?
In our typical case, mobile conversion goes from 0.8 % to 3.9 %, nearly 5x, by fixing speed (LCP 1.8 s, INP 150 ms), integrating Wave and testing the CTA.
Why fix Core Web Vitals before everything else?
Because 60 % of mobile traffic leaves if LCP exceeds 5 s. Testing a CTA or visual on a slow page is pointless: we fix LCP and INP first, then optimize the journey.
Is Wave payment integrated into the landing?
Yes, customers order and pay via Wave in two taps, with no risky redirect. This cuts abandonment at payment, the step where most sales are lost.
