We noticed that a lot of our users do not necessarily speak English as their first or even second language. That's why we've added a translation feature to our website to make the website usable for those people, without having to use third party tools (that generally do a very bad job at translating pages).
The goal is to first translate all the main pages. We've added translations for both Dutch and Spanish. The first because it's my own native language and the latter because we noticed a fair share of our users come from the Spanish speaking part of the world.
We're still experimenting with this, as right now it seems to have a bit of a negative effect on our search rankings. Next up would be to translate more and more of the website and then to start introducing additional languages.
