Pay-Per-Click (PPC) Advertising

Instant traffic.  It's like opening up your donut shop and five seconds later getting knocked down by eager customers.  Same thing with pay-per-click advertising.  PPC, those paid ads on the top and side of search results, offers up the promise of an instant customer base--but without having to wait weeks, months, or never for your organic results to show up. 

Even though organic results are "free," they are often as elusive as clouds in the sky:  always changing shape, always moving.  Even though PPC is rarely a rock-solid guarantee of ranking, it does provide more certainty than the organic results.
