If I’m honest, Facebook ads feel confusing because they’re not really about ads anymore — they’re about data. Facebook’s algorithm only works well when it clearly understands who converts and why. When tracking is broken, everything looks random and frustrating. That’s why learning how events, attribution, and optimization actually work changes everything. A big turning point for me was understanding server-side tracking and how tools like facebook conversion api google tag manager help Facebook receive cleaner, more reliable signals despite privacy restrictions. Once you fix the data flow, ads stop feeling like magic or chaos and start behaving more predictably. Facebook isn’t guessing — it’s reacting to the signals you give it.
