The 1st time Growify came to AS i bought but did not test as i lacked the Eur currency and, even if they rolled it out, i had other softwares in my list, so decided to refund. That was a mistake. I decided to pull the trigger now and i have to say it's been a great decision. I was able to integrate with my Shopify store easily and the data it will provide about ads and attribution is solid and super-helpful, helping us to reduce costs from non-performing campaigs.
What i lack is deeper details about products revenue, it only lists the last 12 and i have putler that does much more in that sense, but doesn't cover attribution.
I'll probably match this with Fraud Blocker and i think it can be a win-win solution to optimize further our ads strategy.
I hope they will improve on the product data they show, so we can even have more product-driven data.
I tried to reach to them, and the reply was not super fast or "precise" (i asked about the power pixel not updating, but after 20min it was working), but maybe they've been overwhelmed with request and i didn't push more as it's been resolved automatically.
All the best!
