Running many campaigns at once sounds smart, but it often causes problems. Each campaign needs time, focus, and money to work well. When you run too many, results get mixed up and nothing gets full attention. For beginners, one or two campaigns are usually enough. This helps you track results clearly and learn what works. Bigger teams with more tools can handle more, but they still plan carefully. It is better to do a few campaigns well than many poorly. What approach makes sense here for most teams today?
