Grem if you are going to do article marketing, make sure English is your first language or have it written by someone who writes in perfect English.
I’m seeing so many articles in my space right now that are clearly written by someone who doesn’t write in English as their first language. Your credibility is shot to pieces before you begin if it sounds wrong. Yes, you may still get the link juice, but if you’re only spinning articles then you don’t come off sounding like you have anything of real value to offer and visitors will move on.
This is assuming you’re targeting English speaking niches.
