Pay-Per-Click or PPC is one of the most commonly used methods of advertising to drive traffic to the website. They are more prevalent with search engines of first-tier. They are widely preferred as the advertiser pays the publisher only on the actual clicking of the ad. As it is an essential component of digital marketing, hence we should exploit its benefits which help to maximize the profit margins.

PPC has pretty much existed since the late 1990s when GoTo.com began charging for top placement in its search engine. Google didn't catch on for many years later, and now, of course, everyone knows about pay-per-click whether it's Facebook Ads, Google Ads, etc. Was there some other point to your post that I'm missing?
