The verdict
For a small team, pick TikTok Ads first if the audience fits, and pick Revealbot only later. A channel you have not tested does not need automation. Run a fixed-budget test with native-style video and judge it on cost per customer.
Pick Revealbot when you spend meaningfully across several platforms, TikTok included, and a missed day costs real money. Rules apply the same logic across all of them.
If you only run one small TikTok account, the platform's own tools and a quick daily check are enough. Automation scales mistakes as fast as wins, so I would not add it before the basics work.
