Even if that is not the case with your account, I can assure you that there is not much you can earn with info links even when you use it on your own website without any kind of restrictions.
Live....and Let Live!
I find that the harder I work, the more luck I seem to have.
This is Sandy from Infolinks. Glad to be joining the conversation. There are a few things I though you should know.
You don't need to have a big site in order to earn with Infolinks. We have sites from all types and sizes that work with us for many years. We have a large variety of smart ads that suit different kinds of needs. In addition to that, Infolinks is both a great AdSense alternative and a compliment – so you can definitely use both at the same time and get great results.
Regarding your income – it takes our algorithm a few days to study your site, and to start earning. So please be patient and give it chance :)
You can also contact our support team for some great optimization tips that will help you get the best out of our services - firstname.lastname@example.org
Thanks and have a great day!
You need a good traffic, at least around 1000 on your pages if you want to earn something solid from Infolinks. I was making around $6-$8 from it when there was no restriction regarding the ad units allowed on our pages. However, now both my traffic is down as I am not writing that frequently and also as my ad units are very less my earnings from Infolinks are in the same pace as of everyone else.
Let me put this in perspective, if you are making $100 from AdSense monthly, only then expect to make around $5 from Infolinks in the same month.
