So, I have identical Facebook ads running in Canada and the US, started this ad first in Canada. Today I noticed that the US ad had caught the Canadian ad in total clicks. This is also the most effective ad I have in every country I'm running ads, BTW. US: Clicks= 101, Reach 1146, Impressions 1239, cost .12/click Canada: Clicks= 101, Reach 2326, Impressions 2638, cost .18/click Same ad is running cheaper in Australia and Uk than in Canada, .16 and .11 respectively, but not sticking much money there right now. Despite the UK being cheaper, the click:reach ration is best in the US. Part of this could be a higher saturation of Kindle Unlimited subscribers in the US, as the ad emphasizes KU. Nonetheless, I found it interesting how differently the ads were performing in these two countries.
