Do Book Marketing Services Really Help Authors Stand Out Today?

[aimee]

I keep hearing writers talk about using book marketing services , but I'm wondering whether they actually make a measurable difference in visibility and sales. With social media, ads, and author platforms more accessible than ever, is hiring these services still necessary? What specific strategies do they offer that authors can't effectively handle on their own? If anyone here has tried them, did you notice real improvements in reach or engagement? Curious to know whether these services are truly valuable or just overhyped.
