the A/B test of one of my clients (in the b2c vertical) showed (for their site with their users) that people clicked more pages (which was kinda expected), and stayed longer on the website overall - with pagination (instead of endless scrolling).
some other metrics (we call them "item views") went up as well.
but it must be said: users of that site special, they actually want to find something, so they are (mostly) not casual users.
i remember a case a few years back on a travel site where we had a different experience, time on site went up after we ditched pagination (but that site also had horrible page load time, so every page view was a great opportunity to leave the site, so well, it's all interconnected)
