Is a TikTok marketing agency worth it for a small business?

I run a small business and keep hearing that TikTok is where a lot of attention is right now, but I honestly have no idea where to start. Making videos is one thing, but coming up with content ideas every week and understanding what the algorithm wants feels like a completely different job. That’s why I’ve been looking at using a TikTok marketing agency , but I’m curious whether they actually make the process easier or if success still depends mostly on luck and trends. Has anyone here worked with a TikTok marketing agency and seen a real difference in growth or customer enquiries?
