Adf.ly is great for publisher accounts, but for advertisers it’s a pretty poor choice. Adf.ly does get an extra star for the ability to have publisher and advertising accounts under the same account, however, this doesn’t make up for it’s inefficiency.
After several test runs, one including my best converting product did not convert as seen on these test accounts.
This resulted in 0 conversations, so all in all it was a complete waste of money, other than gaining the knowledge of it not being an effective campaign tool.
Hope this helps save you money and not waste money advertising on adf.ly.
