What is PTC?

Paid To Click is an online business model that draws online traffic from people aiming to earn money from home. Paid-To-Click, or simply PTC websites, act as middlemen between advertisers and consumers; the advertiser pays for displaying ads on the PTC website, and a part of this payment goes to the viewer when he views the advertisement.

In addition, most PTC sites offer a commission to its members for signing up new members (similar to many affiliate marketingprograms online), or they may pay members a percentage of the clicks that their referrals make as an ongoing commission.

The viability of the PTC business model has been questioned, as fraudulent clicks have ramped up the expenses for advertisers.With lawsuits filed against the internet search companies, the burden has been placed on Google, Yahoo and others to determine valid clicks from fraudulent ones.

This should not be confused with PPC where advertiser pays the site per click generated from any user
