How can I promote my app on google play store ?

Hi

I have published my app on play store, so how to increase the download, there is campaign of Ad Word, but its cost not affordable for me, so anyone knows good alternative for it.

Please suggest!

Thanks,

RW

Here are two websites can help you:

1- CPIMobi (0.09$ per install)

2- APP2TOP (0.04$ per install)

Attention: Don't look only at the price, open the 2 sites and compare their service.

Thanks for the reply, I will check these sites, but Is there any other free option.

I don't think that there are free sites.
