impressions vs clicks

Im driving traffic to a landing page for an affiliate project. I'm only using one ppc source at the moment, just testing the waters. Something that stands out to me is that I have about 18k impressions, with only 13 clicks. I'm trying to change up the title and description. Can someone help me understand this ratio, and how much it can vary between different ad sources.

I am having the same problem. 5000+ impressions, 0 clicks.

What exactly is your CTR? Numbers you've mentioned and the ratio doesn't make any sense to me.

@OP, your CTR is ~0.07.

That's pretty low with paid advertising. Your best bet of increasing CTR is image. Split multiple banners. Once you get a decent CTR then split test the ad copy on your banner.
