I'm an independent developer which struggle for the best marketing technique for long. From my pass experience, FB used to be the best in 1.5 year ago. However, right now it becomes less and less effect as I used to get about 6-7% hit rate but now I only got less than 1% hit rate which waste me a lot of money.
Does anybody have any recommendation on below:
1. The best and practical app review sites?
2. The best paid per install web sites?
3. The best and trustable marketing companies?
4. Any other best promotion methods?
I'll write up some conclusion after receiving your valuable comments.
