Hey Isabel. I would definitely create your blog in your native language if that is the one that you write better in. If your English grammar isn’t impeccable, you will have a hard time getting a loyal audience of English speakers. A blog written in English has the potential for a larger audience, but a blog in your native language will have less competition and the potential for a far more LOYAL audience. I hope that helps!
To all the bloggers out there…STOP sucking up to the very small, elite and narcissistic group of self-proclaimed influencers out there. If you all stop treating them like they’re special, they will not longer by special and therefore some of us who aren’t in there secret society will be seen as knowing what we’re talking about too! This isn’t High School, grow up and read someone else’s blog already!
