At that low of a budget 200 keywords is a bit overkill. Also, stay away from broad especially at $10 a day. I manage $2.5 million a year in adspend and 90% of the time I’m not utilizing broad match unless I need to expand reach / scale spend.

But yes, the first part is true about campaigns taking time to collect data and learn to optimize efficiently. Google ads is an investment up front. Could take around 2-3 months for you to see very strong performance.
