This data is according to a tremendous site BuiltWith.com.
Very interestingly, according to this, the eCommerce market is so-o scattered here in Finland. And so evenly scattered. Also: the market shares are quite surprising. I still have to analyze these figures, and check this and that, so I’m not saying much here right now.
But one detail I have to mention: the 2019-04-17 data shows, that in Finland there are 9 490 web shops, while at the same time in Sweden there are 3x more, total of 28 188 shops. Well that is something! Wow! In comparison, there are 20 358 shops in Denmark, and in Norway 11 886 shops.
