I just signed up on this forum today but I have been a regular reader of this forum. I have learnt a lot of stuff from this forum and I thank all the contributors for that.
I have a couple of questions:
1. I recently ran a campaign on US and got around 0.7 CPI on day one, the CPI was 0.82 on day 2, 0.95 on day 3 and now it has crossed it 1.00 USD. I wanted to ask if it is normal and does the CPI really increase with number of downloads?
Please note that I have changed the creatives but that didn't help either.
2. Should the new creatives be added to new adset or an existing adset? What does your experience say?
