Facebook update

So, I went ahead and paid for a FB ad on Friday; so here's an update. I received 48 clicks directly to my website and spent $15.01 of my $98 budget. The ad reached 45,508 viewers out of 4.5 million. My son read my ad and said it was misleading and convinced me to change it. He said it sounded like I was selling a how-to guide to teenage girls. He also convinced me to increase my demographic from only high school girls ages 14-17 to include male and female, college and high school ages 13-18 and my demographic went from over 300 thousand to 4.5 million. Here's a new learned crumb of information; I did't know I could change the bid per click depending on the volume of clicks I was getting. The original bid was for .41 per click by Sunday morning when the volume of viewers increased and my suggested bid went down to .23 per click so I reduced it to .25 per click. But the funny thing, the number of clicks have slowed down so now I'm thinking to play around with the bid and increase it to say .35 per click and see what happens. My goal is conservative, I was hoping for at least one sale but reading online articles on marketing says that a person has to see an ad an average of 7 times before making a purchase, so my 1 sale goal may be too ambitious. Keep ya posted.
