Ask How can a company figure out which marketing channel is actually bringing in the most customers?

Tracking where customers actually come from can be confusing when a business runs ads, posts on social media, and sends emails all at once. Using tools that track clicks and conversions helps show which channel leads to real purchases, not just visits. Some businesses also ask new customers directly how they found the brand, which adds another layer of useful information. Without proper tracking, it becomes easy to waste money on channels that only look successful. What method do you think gives the clearest picture of which channel truly works?
