Believe it or not, some of the best traffic on the Internet is free. Therefore, if (1) you have a new business that has to be promoted to start making profit, or (2) your business is not new but you want more customers to make more money and have a more stable and long lasting business, then Targeted Traffic is the solution.
Then, by using AdWords ad scheduling for your successful campaigns, you can ensure they are only being delivered during those high-converting buy traffic times, preventing you from spending money delivering ads to your target audience when they are less likely to be online.

Usually, it's a bit more than $0.10 because there's a lot of competition these days for Bing US traffic, but you can still manage to get cheap clicks if you have good landing pages and keywords that will increase the Ad CTR and thus lower the over all CPC.
What you want is to keep doing more of what's working (more guest posts on blog that send quality traffic, more ads on site that send traffic that converts etc) and stop putting in the effort in traffic sources that don't convert - either low total conversions or very low conversion rate.

Even if you have countless numbers of online visitors flocking to your site on a daily basis but none of them ever converts - turns to targeted leads or even sales - then all these websites hits that your site is accumulating are just worthless statistics that wouldn't do your business any good.
But that said, I will be honest with you here and tell you that I haven't promoted clickbank products in years, because I think they are not good enough and mostly they are just scammy… but I did use Push traffic to get conversions for CPA offers such as supplements, creams, accessories etc… so if it's possible with CPA I think it should be the same with Clickbank too.

If you know how to find and target the right users, however, you may be able to build a huge fan following and consistently drive targeted traffic to your website from it. Natural Area Rugs is a pretty good example of what we are talking about, as it managed to build a with a pretty impressive engagement rate, which is definitely quite an achievement given it's an e-commerce business (which can probably be a huge challenge to promote on social media).
