Hello
Both sites have very poor Swedish. The site with coilovers might not be disastrous, but on the site with body armor, my feeling is that a majority of the words are misspelled, in the wrong place, or simply the wrong word.
Start by fixing the language on the sites. After that, it is probably easier to make an analysis of the conversion rate.
Also remember that organic traffic from search engines are relatively high-converting in general. If the Swedish sites are new and do not rank for anything particular, it is not strange that the conversion rate is lower than on an established site.
As a side note. The site with the body armor looks more like someone trying to sell (illegal) weapons than a shop for body armor. I would have exchanged the weapons images for product images. Now, I have in itself difficulties with weapons in general, and I'm not your target audience, so perhaps you should not take that as a truth.
