The verdict in three sentences
An optimised B2B brochure site rebuild targeting emerging markets costs 800,000 to 2,500,000 FCFA (roughly 1,200 to 3,800 EUR) in 2026 depending on page count and animation level. The technical optimisation (AVIF/WebP, lazy loading, caching) aims for loading under 3 seconds even on unstable 3G, which is decisive for a mobile-first market. An offline-first PWA adds around 30 % to the budget but enables browsing without connection and a home-screen icon.
The rebuild price by tier in 2026
The market aligns on three clear tiers. The price gap reflects page count, design depth and network optimisation effort, which is critical against limited bandwidth.
| Tier | Pages | 2026 price (FCFA) | Included |
|---|---|---|---|
| Starter | 5 | 800,000 - 1,200,000 | Responsive design, basic SEO, WebP |
| Growth | 8 - 12 | 1,300,000 - 1,800,000 | Blog, analytics, AVIF + lazy loading |
| Premium | 15+ | 1,900,000 - 2,500,000 | Animations, advanced SEO, offline cache |
| PWA option | - | +30 % | Offline-first, home icon, push |
| Bilingual EN/FR | - | +200,000 - 400,000 | Hreflang, dual content |
These figures include integration, testing on real mobile networks and training to update content.
3G optimisation: what makes the difference
On a 3G network at 1-3 Mbps, every kilobyte counts. The techniques below turn a heavy site into a fluid one and directly affect bounce rate and mobile ranking.
| Technique | Typical weight saving | 3G loading impact |
|---|---|---|
| AVIF/WebP conversion | -40 to -70 % on images | -1 to -2 s |
| Image lazy loading | -50 % on first screen | -1 to -1.5 s |
| JS/CSS minification | -20 to -35 % | -0.5 s |
| Browser cache / CDN | Reused assets | Near-instant repeat visits |
| System fonts | -100 to -300 KB | -0.3 to -0.7 s |
| Offline-first PWA | Content served offline | 0 s if already visited |
A site moving from 6 seconds to under 3 seconds mechanically wins conversions: every second saved cuts the abandonment rate by roughly 7 to 10 %.
Mini case study
Sarah, COO of a logistics firm in Amsterdam selling into West Africa, runs a 2019 brochure site that takes 7 seconds to load over 3G, driving prospects away. She orders a Growth rebuild at 1,500,000 FCFA with AVIF conversion, lazy loading and caching, plus the PWA option (+450,000 FCFA), i.e. 1,950,000 FCFA. Loading drops to 2.4 seconds and the site stays browsable offline. With maintenance at 45,000 FCFA/month, her first-year total reaches 2,490,000 FCFA. Contact form submissions double within three months, paying back the investment in the first quarter.
