Taking the plunge with a Facebook ad

Set up my first FB ad campaign, it took 15 minutes. The budget; $0 .40 pay per click, $7.00 per day, 2 weeks, which comes to a grand total of $98 by the time the ad campaign is done. All I had to do was upload my book cover, add a catchy phrase in 50 words or less, set up my demographics (U.S. only, English, girls, 13-17, literature/reading). There were 352,000 girls that met that demographic. Breaking it down further, it gives me roughly 18 clicks per day. I sacrificed a sexy pair of black leather boots at T.J. Maxx for this add; we'll see how it goes,
