After a while trying FB and bingo traffic campaigns, recently found the CPI or eCPA traffic,
I have active accounts with maxbounty, peerfly, clickbank etc,
planning to start a new campaign with CPI or eCPA,
which seems to be a guaranteed investment since the traffic source will charge per action,
if anyone done this before, please share some advises or comments to abbreviate the way to see some results quickly and safely,
thanks for the advise or recommendation in advance.
