Never paid attention to this before and am beginning testing but curious if anyone had any experience with this and what the results were

Just got notification that video campaigns will be changing to demand gen campaigns in 2025 March

I'm trying to create re-marketing lists of anyone who viewed my video as an ad - i can myself track tens of thousands of views but when I create this list it shows 0 people inside of the youtube and in gmail it shows 10,000 - how can this be? Any advice

Trying to scale YouTube adspend from $1.5k-$2k per day to $10k per day but I don't think our conversion events/tracking is setup correctly. The leads numbers reported are always WAY off compared to what makes it in our CRM. We use hyros to track the true numbers but I want google to be able to optimize well. Anyone a master of this and open to help? Will happily pay you.

Is it better to choose "Maximize Conversions" or "Target CPA" for a brand new ad account and campaigns with "Leads" goal?
