As stated in an article here http://innovativecritic..com.ng/2016/02/nigerian-commonadsense.html


Heres the scenario; with the dollar getting stronger due to the decline in oil prices, its becoming more expensive for the companies that are interested in the Nigerian market to place ads.

E.g If it cost you $25=N5000 (at $1 to N200) for 1000 Facebook likes, it will now cost you the equivalent of N7,500(at $1 to N300) for the same 1000 Facebook likes at $25.

So you see, if Online Ads were traded in Naira, it will be better for the advertiser but there not they are traded in dollars.
