The verdict in three sentences
Meta Ads remains in 2026 the cheapest e-commerce acquisition channel in West Africa: CPM of 1 to 4 USD and CPC of 0.05 to 0.25 USD, far below European rates. A profitable campaign targets a ROAS of 3 to 5x on acquisition and 6 to 10x on retargeting, with a test budget of 100 to 300 USD/month before scaling. The number-one success factor is not targeting but the creative: a native video outperforms an image by 30 to 50%.
Benchmark costs and targets
Before launching, you need the 2026 cost benchmarks for Lagos, Abidjan and Dakar.
| Metric | 2026 range | Healthy target |
|---|---|---|
| CPM | 1-4 USD | < 3 USD |
| CPC | 0.05-0.25 USD | < 0.15 USD |
| CTR | 1-3% | > 1.5% |
| Acquisition ROAS | 2-5x | >= 3x |
| Retargeting ROAS | 4-10x | >= 6x |
| Test budget | 100-300 USD/month | 150 USD |
Below a 2x ROAS on cold acquisition, cut or rework the creative before anything else.
Campaign structure and allocation
A well-split budget avoids burning money on the wrong audience. Indicative split for 200 USD/month.
| Funnel stage | Budget | Expected ROAS | Goal |
|---|---|---|---|
| Cold acquisition | 120 USD (60%) | 2-4x | Find new buyers |
| Visitor retargeting | 50 USD (25%) | 6-10x | Recover the undecided |
| Cart retargeting | 30 USD (15%) | 8-12x | Convert hot carts |
Retargeting is 40% of the budget but often more than 60% of attributed sales.
Mini case study
Aminata sells clothing in Lagos. She invests 200 USD/month (about 120,000 FCFA) in Meta Ads with a video creative. Her CPC is 0.12 USD, generating about 1,660 clicks. At a 2.5% conversion rate, she gets 41 orders at a 22,000 FCFA basket, i.e. 902,000 FCFA in sales for 120,000 FCFA spent: a 7.5x ROAS thanks to retargeting weight. Without the native video, her ROAS would fall to around 4-5x.

FAQ
What budget to start Meta Ads in 2026?
A test budget of 100 to 300 USD/month is enough to validate a creative and a product. Only scale after finding a stable ROAS >= 3x.
Video or image, which to favor?
Native video. It outperforms image by 30 to 50% on CTR and ROAS, especially in vertical format for mobile.
What ROAS counts as profitable?
3 to 5x on cold acquisition, 6 to 10x on retargeting. Below 2x cold, the campaign loses money after product and delivery cost.
Is retargeting worth the investment?
Yes, it's the best ROI: 6 to 12x. Allocate about 40% of the budget to it; it often generates most attributed sales.
Should I target broad or precise?
In 2026, the Meta algorithm performs better with broad targeting and a strong creative. Let the AI find buyers rather than over-segmenting.
