Lets say Im going to start with 10 banners and let them run until I have something like 100 clicks each.
Ok, great! I found my top two performing banners and I let them run for a day and make a small 1% profit.
now I want to take it to the next level. I want to get my banner CTR up... well what does that process look like?
My two top banners have red text and a beefy looking dude (cause Im pushing muscle)
Do I just make new variations of those two banners?
If I wanted to test
different headlines
different bullet points
different call to action
multiple images
different color text
different style
I would end up with 100 banners!!
So what is the process like for you? It is going to be different for every vertical, every niche of course.
Everyone does it differently - here's how I would do it:
-For the angle(s) those 2 banners were made from, brainstorm additional headlines to test.
-Take the 2 headlines and match them up with different images.
-Take the image(s) from those 2 banners and match them up with different headlines (ones that are showing promise thus far, and also new headlines written using the same angle).
Once I've nailed down headline + image combinations that work, I would then use a couple of the best banners to test multiple calls-to-action, etc.
