Shiny object syndrome in digital marketing is basically when people chase every new trend, tool, or platform that pops up. It's exciting at first, but hopping from one thing to the next can spread your time, money, and energy way too thin. Instead of getting good at one thing or really making your campaigns work, you end up with a bunch of half-finished projects and meh results. The trick? Stick to a solid plan, only try new stuff here and there, and focus on what actually makes a difference.
