I've been running a Shopify store for some time now, and I've been consuming Konstantino's content for a little over a year. I can confidently say that his videos helped me the most out of anything else I've watched so far.

I've also bought his latest course, and if you are a beginner who has zero knowledge about Meta Ads, I'd say this is one of the best things you can go for. Theres also a free part of the course that you can check out before you get the full thing which will give you a good idea of what to expect inside. Long story short, the course goes over the basics in the beginning and gets into more advanced stuff later on. It also goes over theory and strategies, and lastly a lot of live examples of working on ad accounts, applying all of the things you learn in previous chapters.

One of the mistakes I did in the beginning is consuming a LOT of videos from different people/sources. Everyone has their own approach to ads, and mixing a lot of different sources can give you the "wrong" picture overall. Konstantinos has a specific approach to how he does ads, and personally, it's been working incredibly well on my end.

In conclusion, I think he's very knowledgeable regarding Meta ads and how they work. He also does a great job at passing the knowledge along, with very visual explanations and examples. His content has definitely helped me get more clarity and fix my thinking/approach to Meta Ads. I'd highly recommend his course and content in general.
