So i tried tap for taps paid promotion out for my new app Pexture. The result came out pretty bad in my opinion. An install rate of 0.0002%. Definitely not worth it.
The image I use was the tft standard one for the banner and my own appwall-image. My icon isnt the best and the look of the banner isnt very self selling of the content.
Allmost all of the impressions where ont the banner. I will change the banner to a self-designed one and try another campaign with paid promotion.
