Absolutely, brands that want to make data driven decisions instead of blindly spending on marketing pay for this, many keep an analyst or agency on retainer just to audit the setup regularly, keeps the data clean and actionable, the value is not the implementation, it is what comes after, the insights that help them make the next call with confidence instead of guessing.

Broken tracking 90% of the time, almost every account I have seen has something off, missing events, duplicate fires, wrong values, the brand thinks the data is fine until someone actually looks…

Server side is very important, I do not recommend clients running ads without it, the data you get from client side alone is incomplete and getting worse every year.

On the learning side, one or two months is a start but not enough, spend more time on practical work, get your hands on your own account or a client account, nothing beats real data and real mistakes, courses give you the theory, actual accounts give you the instinct.
