Has anyone compared the following?
– Ads in English, shop in English
vs
– Ads in Native (e.g. Russian), shop in English
vs
– Ads in Native, shop in Native
I understand that the more native the better due to familiarity effects (although, there are surely outliers). But has anyone actually made statistical comparisons?
If so, what price level were the products? Did maybe low price win over lingual uncertainty?
