When it comes to pay-per-click (PPC) advertising online, one name stands out above the rest: Google AdWords. If you’ve ever seen the paid results at the top of the page when you run a Google search or seen a rotating banner ad on your favorite website, congratulations, you have experience with Google ads! For years and years, Google AdWords has dominated the PPC advertising business, giving businesses previously unprecedented opportunities to reach highly targeted audiences online. Google was unchallenged in its PPC supremacy. In recent years, however, a new contender has arrived.
