What are pay to click sites? 

Pay to click (also called PTC) sites are sites that pay you for clicking on an advertisement and looking at it for a set period of time, usually 30 seconds.

Can I make money with this?

A small amount.  You can NOT make an income off of this, but you can make a few dollars a month.  I only recommend the sites as something to do while watching TV or a movie.  Spending time you could be working doing these sites is a waste of time.  (Sorry, guys, I promised honest reviews!) 

Aren't most of these sites scams?

Well, in a word, yes.  There are A FEW that are honest.  The "best in the business" is Neobux (see the banner at the bottom of the post).  They pay via Paypal and you only need $2.00 in your account to cash out.  You also earn .01 per ad.  A bunch of the sites only pay .005 or even .001 per click.  For the .001 per click sites, you have to click 10 ads just to make a cent!  Avoid these sites at all costs.  Also avoid any site that requires you to pay to sign up. 

Are there any other PTC sites that are honest?

A few.  I'm working my way through the "best recommended" ones and will post the ones that are honest.  As I work my way through them, I will also posts the ones that are scams!  

If you have a PTC site that you want me to check out, feel free to e-mail me: jenniferlandsberger@yahoo.com. 

Neobux below is the best that I've found.
