Best strategies for maximizing cashback casino bonuses?

I'm trying to get into the world of online casinos and I keep running into these cashback offers. I've heard some amazing things, but the fine print always seems confusing. Specifically, I'm wondering about the difference between pure cashback and cashback combined with a deposit bonus. Are there any common traps I should look out for, like hidden wagering requirements that make the cashback worthless? Any veteran players who have successfully navigated this area and can share their best strategies or recommended sites would be hugely appreciated. Thanks in advance for the help!
