One of my forum sites has terrible bounce rate and pages/visit . I recently discovered something that grabs users attention, and lowers that bounce rate by ~5% and ups the pages/visit by ~15%. However, this is at a cost of ads not being clicked nearly as much.
So should I keep the change and hope that rankings improve because of the 'happier' visitors that Google sees, and hope that traffic goes up to make up the difference in lost ad revenue?
