Nigeria is the most populous country in Africa and one of the busiest English-speaking segments of Instagram. Afrobeats, Nollywood, streetwear and finance blogs are what the local feed revolves around. This position is taken when volume is the point: a cap of 100 000 per order and a pace of up to 75 000 a day let a big request close within a couple of days without splitting it into parts.
The refill covers thirty days after the order completes: if some followers drop off, send support the order number and the lost volume is added again. That insurance is exactly why this position is chosen for long campaigns rather than for a one-off spike.
The geography. Instagram only shows an aggregated country breakdown of an audience, so the origin of each individual follower cannot be confirmed — the Nigerian origin rests on the geo declared for this position. We do not present that as a proven fact.
There is one practical consequence: a visible Nigerian share will appear in the aggregated statistics of the profile. If you show those statistics to an advertiser who buys a Ukrainian or European audience from you, account for the shift in advance — there will be nothing to argue with once it is in the report. For reach, social proof and the English-speaking West African scene the position works; for reporting to a local advertiser it does not. A delivered order is not refunded.
