YouTube Ads Audit

I run a digital marketing agency that does +$1M/yr in sales and a daily ad spend on YouTube of $300/day with several different Ad Sets running VSLs for my offer.I'd like to scale Ad Spend to $1,000/day or even $2,000/day as we have really good LTV/CAC and I want to grow this into an 8-figure agency.What is your advice for optimizing YouTube Ads?Do you recommend a tracking software like Hyros?How can I enhance my funnel to increase conversions?What are some things I might be missing?I would love if you could answer all these questions and any case studies you can share would be great.Looking forward to hopping on a call.Thanks!
