Do you think I should bother with a pay-per-click ad campaign?

[Jake]

Typically a sales site requires 50 to 200 clicks to secure one click, those click costs add up quickly, those relying on paid traffic spend quite a bit of effort on optimizing the conversion rates of their site using split testing, which ultimately makes organic pay off better too.

You might try Facebook ads that send people to a fan page for your site, where you can make a more personal connection and if done right build up some lines and a following from relatively cheap ads.
