It might have something to do with the how you worded you ad and the search keywords that you listed as relevant. You're not going to get many clicks if people perceive your ad to be "scammy" or unintelligible.
You have to be more specific with your keywords and target a specific audience that are looking for your stuff. If you sell, let's say, socks do not use "clothes" as one of your keywords. I hope you get the idea.
