In that case I guess an article like this may help you to see where I am coming from. https://www.entrepreneur.com/article/288703

I'm not sure if you know but Renderosity added Google Analytic support for vendors here quite a while back. You can see exactly where the traffic comes from that reaches your store page, which helps to analyse what forms of marketing truly lead to actual purchases here. And no surprise 95-99% of traffic comes from newsletters, sale pages or the front page of the marketplace and even some more unexpected obscure sources occasionally. Maybe 1% traffic that reach your store page comes from other external personal marketing efforts and less then that make an actual purchase. My advice would be to match that to the effort put in unless you are really looking to achieve something outside of the box. Of course that is has been my personal observation, mileage may vary I guess.

Entrepreneurial online marketing can work and work very well in some cases, but not in all cases all of the time. Trial and effort and at least hearing out advice from those that have tried before is often a good gauge to get a bearing on when it may not work the way you expect it would. The detail is often in small differences.

Ok, I'm out now :) Really need to get some work done to back up all my talk.
