The verdict in three sentences
A website migration without SEO loss in Dakar in 2026 costs between 1,000,000 and 3,000,000 FCFA depending on site size and URL complexity. The critical line is not technical but methodological: an exhaustive 301 redirect plan and 3 months of Search Console monitoring. Without that plan, avoidable traffic loss reaches 20 to 40 % for several months.
The steps of a secure migration
A successful migration is run as a milestone project, never as a simple file transfer. Here is the sequence and the risk per step.
| Step | Deliverable | Risk if skipped | Indicative cost |
|---|---|---|---|
| Audit + URL mapping | full inventory | orphan pages | 300,000-700,000 FCFA |
| 301 redirect plan | mapping table | 20-40 % traffic loss | 250,000-600,000 FCFA |
| Content freeze | frozen version | desynced content | included |
| Technical cutover | go-live | downtime | 200,000-800,000 FCFA |
| 3-month GSC monitoring | indexing follow-up | undetected errors | 250,000-900,000 FCFA |
The content freeze (1 to 2 weeks) is often forgotten: publishing new articles during cutover complicates mapping and muddies indexing signals.
Risks per step and countermeasure
Each step carries a specific SEO risk. Here is how to neutralize it, with the scale of loss avoided.
| Risk | Common cause | Countermeasure | Loss avoided |
|---|---|---|---|
| Lost URLs | no mapping | exhaustive inventory | 15-30 % |
| Missing redirects | incomplete plan | 301 on 100 % of URLs | 20-40 % |
| Redirect chains | cascading 301s | direct redirect | 5-10 % |
| Stale sitemap | post-cutover oversight | resubmit to GSC | 5-15 % |
| Duplicate content | old site still live | clean shutdown | 10-20 % |
Golden rule: cover 100 % of old URLs with a 301 redirect to the most relevant equivalent, never to the homepage alone.

Mini case study
Aminata, digital lead at a financial services firm in Dakar, migrates a 180-page site to a new host and a shorter domain. Her organic traffic drives 12,000 visitors/month, generating 30 monthly quote requests. Migration quote: 2,100,000 FCFA (audit + 301 + 3-month monitoring). Without a plan, an estimated 30 % drop would cost her 9 quote requests per month for 3 months, i.e. 27 lost leads. With a high average B2B deal, preserving even 5 of those leads more than repays the engagement in the first month post-cutover.
FAQ
How long does a loss-free migration take? From 3 to 6 weeks for preparation and cutover, plus 3 months of Search Console monitoring to confirm no drop and fix indexing errors.
Must every URL be redirected? Yes, 100 % of indexed URLs must 301-redirect to their closest equivalent. Missing redirects are the top cause of traffic loss, up to 40 %.
Can we migrate domain and host at once? It is possible but riskier. Separating the two operations (host first, then domain) makes diagnosis easier if traffic moves.
How long to recover rankings? With a clean plan, stabilization takes 2 to 8 weeks. Temporary fluctuation is normal; a lasting drop beyond 3 months signals a redirect or content problem.
Why freeze content during cutover? Publishing new pages during migration desyncs the mapping and muddies the signals sent to Google. A 1-to-2-week freeze secures the operation.
