In my exploration of digital marketing, I've found that it's indeed tangible and quantifiable. Unlike traditional marketing, digital marketing allows us to accurately track and measure the impact of our campaigns, thanks to analytics tools. We can see real-time data such as click-through rates, engagement rates, and conversion rates. Not only does this provide immediate feedback, but it also helps us refine our strategies on the go. So, yes, digital marketing is not just a buzzword; it's a measurable, tangible method of reaching customers.
