On the surface, it's not a difficult process. Google will walk you through it and even suggest terms for you to use that others have used for similar products. After your ad appears, Google will even show if it converted. Isn’t that what you really want - to drive traffic and convert sales?
As simple as it may appear to be, it's important to keep in mind that it continues to change - which is why you need a digital strategy to unlock the full potential of your Google AdWords.
