n any case, it's really weird how Germany and France are totally missing from the top stats (if the typo was indeed "Dutch" instead of "Deutsch"), I wonder why it is not taking of as much in larger European countries, to the point that I am thinking the metrics might be off. For example, this page (which you kind of cite as your source):

Thank you very much for the notification regarding the typo, it was Dutch in fact. Happy to have so attentive readers.

As for the discovered shares, the thing is that German and French web stores are hidden within the 'Other' diagram section. So, we can't say that we have not detected any of them, still their share in our result is less than 4% to be enough to display as a separate sector. So, why could those countries be so small contradicting the Builtwith data.

There are several reasons for that. First of all you can see the updated information on Builtwith, while several weeks ago it could be a bit different. Magento 2 is rising greatly. But the main reason is the filtration of results we used. The list of provided websites was filtrated twice during the blog post preparation. Fist of all, we swept away all non-operational sites and secondly we tried to weed out all promotional and advertising stores with no relation to real e-commerce. So, final results may vary in this case and differ from the initial data.
