Paid search is not a set-it-and-forget-it method of marketing. To use paid search properly, you must understand how it is best implemented to drive real-time results while improving organic search results long-term.
Paid search is not a replacement for anything, it should be an integral part of a comprehensive inbound marketing strategy. You can use it to accomplish many of your inbound marketing goals.
You begin by telling Google which keywords you want to buy to trigger your ads to display on their search engine results page(s) (SERPs). You design your ads around these keywords working to make them relevant to the query and compelling enough to get users to click on them. Once users click through, you want to direct them to a landing page where you will try to persuade them to take the next step, buying your product, downloading an offer, or otherwise moving further down the sales funnel.
