The verdict
For a small B2B team, I'd pick Leadinfo. Most B2B visitors never fill in a form, and seeing which companies browsed your pricing page yesterday gives sales something to do this morning.
If you run a busy webshop or a product signup and conversion has dropped without a clear cause, I'd pick Contentsquare. It needs real traffic and someone with time to act on the findings. For a small site, a free tool such as Clarity is enough.
Solid Growth is a certified Leadinfo partner, so weigh that. The two do not overlap, and a larger team could run both.
