I’ve
optimized the campaign to it’s ROI already how come now the ROI
is increasing?
Optimization is a continuous effort, even though your campaign
has reached it’s ROI it doesn’t mean you can leave
it alone but you can check the campaign less often. As new sources
of targeted traffic are dedicated to your campaign each day, it
will affect the ROI as not all site converts in the same rate
which will in turn fluctuate your ROI.
