Of 23 redesign requests Kolonell received in Q1 2026, 14 clients assumed they needed a full redesign when a partial migration was enough — average saving: 480,000 FCFA per project. The right call depends on 6 precise signals, not a gut feel.
TL;DR :
- Full redesign (800K-2.5M FCFA): warranted when brand identity is stale, the stack is dead (Flash, unmaintained jQuery), or the information architecture is unfixable.
- Partial migration (250-600K FCFA): enough when existing SEO converts, content still fits, and only performance or the CMS must change.
- A 60-minute Kolonell audit decides objectively on 6 measurable criteria.
The numbers in 2026
- GSMA 2025: 57% of West African mid-market firms call their website "outdated or slow", but only 19% act within the year.
- Similarweb on a sample of 180
.snsites (SME + institutional): median Time-to-Interactive of 5.8 seconds on 3G, versus a Google Core Web Vitals target of 3.8s max. - BCEAO + ADEPME: 62% of Senegalese SMEs rebuild their site after 4 to 7 years of stagnation — a long cycle that justifies investment.
- Average cost of a serious full redesign in Dakar 2026: 900,000 to 2,000,000 FCFA depending on page count and integrations.
- Typical SEO loss during a botched redesign: -35 to -60% organic traffic for 2 to 4 months, per 9 Kolonell post-mortem audits.
- ARTP: 68% of Senegalese visitors abandon a site that breaks in mobile responsive — making technical migrations more urgent than cosmetic redesigns.
How we decide at Kolonell
Step 1 — 6-signal audit (⏱ 1h)
We check six criteria: (1) design age (> 5 years = strong redesign signal), (2) Core Web Vitals performance (LCP, CLS, INP), (3) existing SEO quality (Search Console positions), (4) tech stack (unmaintained WordPress, Joomla, static PHP 5 site), (5) content quality (2026 relevance), (6) fit with 2026 channels (WhatsApp Business, Google Business Profile, mobile payments). Each criterion scored 0-5.
Step 2 — Real case: Ibrahima Fall, law firm at the Plateau (⏱ audit + decision in 2h)
2018 Joomla site, 22 pages, clean SEO (47 keywords in Google Senegal top 10). Dated but functional design. Problems: slow (LCP 4.9s), no form, no EN translation for the diaspora. Our recommendation: partial Next.js migration preserving URL architecture, light visual refresh, EN added. Quote: 380,000 FCFA vs 1.2M for a full redesign. SEO preserved at 92%.
Step 3 — Opposite case: Omar Ndiaye, fashion boutique in Mermoz (⏱ 1h audit)
2020 Wix site, 7 template pages, zero organic traffic, strong product photos, recently rebuilt brand. Full redesign justified: incompatible stack, nothing to save on SEO, Wave/OM e-commerce needed. Quote: 1.05M FCFA, delivered in 4 weeks.
The 5 mistakes that kill it
- Rebuilding because "it feels old". Fatou Diallo, school director at Point E, was about to spend 1.8M on a facelift while her SEO drove 140 registrations/year. We migrated for 420K and kept the URLs.
- Forgetting the 301 redirect plan. Without a precise old → new mapping, you lose 30 to 60% of organic traffic. It's the number one reason Dakar redesigns fail.
- Ignoring content during the redesign. New design + same vague copy = same zero conversions. Copy weighs as much as pixels.
- Underestimating integration impact. CRM, forms, Meta/Google pixels, Analytics, Zapier: a migration breaks 4 integrations on average when they aren't listed upfront.
- Choosing the cheapest vendor with no SEO plan. A "pretty" 250K site that loses 70% of traffic = pure loss of 12 to 36 months of revenue.
Comparison table: redesign vs migration
| Criterion | Partial migration | Full redesign |
|---|---|---|
| Dakar 2026 price | 250-600K FCFA | 800K-2.5M FCFA |
| Delivery time | 2-4 weeks | 5-10 weeks |
| SEO preserved | 85-95% | 40-70% (risk) |
| 301 redirects | Partial | Massive (all URLs) |
| Reworked content | 10-30% | 60-100% |
| Traffic loss risk | Low | Medium to high |
| When to choose | Recent stack, live SEO, brand OK | Stale brand, dead stack, business pivot |
| Post-project maintenance | 15-25K/month | 25-45K/month |

How we do it at Kolonell
We ship two clear options: Partial Migration (from 350,000 FCFA, 2-4 weeks) preserving SEO architecture and modernizing performance + mobile UX + integrations, and Full Redesign (from 900,000 FCFA, 5-10 weeks) starting from a blank slate for design, copy and stack, with an exhaustive 301 redirect plan and 90-day post-launch Search Console monitoring. SEO guarantee: if organic traffic drops more than 15% within 3 months, we work for free until it recovers. At Kolonell we refuse "cosmetic" redesigns without an SEO plan — that's the number one cause of commercial disasters.
"We thought we needed a full 1.5M redesign. Kolonell diagnosed a 420K partial migration would do. Outcome: SEO preserved, site twice as fast, 22 new case files in 4 months." — Ibrahima Fall, partner at a law firm, Plateau, Dakar.
