On the jealousy for men, I can see a conversion rate which is pretty high 2-3%
but page traffic is only 630 page views for 3 months.
So, in that case, the core limiting factor is not the conversion rate, it is traffic.
In all cases, traffic is ALWAYS a limiting factor because even with a conversion rate of 0.1%, lots of traffic would still mean lots of sales.
But of course, working on both conversions and traffic side by side is essential.
Anyways... that's just a quick observation on that. Sometimes, it's pretty pointless to fine tune the conversion rate from 1% to 2% if there is very little traffic coming in....
It's essential to be smart with where you put your effort and energy if you don't want to miss the point
