Plausible starts cheap, but the pricing scales with your site traffic, so growth comes at a cost. More importantly, it only offers top level insights, not the depth needed to spot click quality or potential ad fraud. Hitprobe also offers plans that scale, but it delivers more than just visitor numbers and entry/exit data. It's built to help you protect your ad spend, understand the real value of each click, and make data-backed decisions that help drive growth.
