How is digital marketing success measured?

That’s a solid summary. I’d just add that it really depends on the business goals. For some, engagement (likes, comments, shares) matters most, while for others it’s purely ROI or conversions. Also, tracking things like customer lifetime value (CLV) and cost per acquisition (CPA) can give a clearer picture of long-term success, not just short-term campaign wins. I’ve been following insights from The Digital Geek lately, and they also emphasize focusing on lead quality and retention, not just numbers.
