Yeah definitely don’t buy into IG marketing courses unless they have lots of great reviews. I have yet to find a decent course that gives as good content as this forum!
What works for other users’ accounts doesn’t always work for your accounts. That’s because accounts have different trust score. So, don’t give up when you get blocked while you’re using “best settings” from other users. Try to find your own “best settings” through trial and error.
Make sure you begin in a niche you are genuinely interested in or personally relates to you. The rest of the basics will make intuitive sense to you from there. Money can come later, so also make sure you enter those niches without the expectation to make money (at least right away).
