Paid to click (PTC) is an online business model that draws online traffic from people aiming to earn money from home. 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.
Controversies
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.
