You control the cost of search engine marketing and pay nothing for your ad to simply appear on the search engine. You are charged only if someone clicks on your ad, and only up to the amount that you agreed to for that click. That’s why SEM is also known as pay per click (PPC), because you only get charged for each click that your ad generates. No click? No charge.
Your strategy defines your audience, your platform, your content, and even how you measure success. For example, if you sell a product for a young demographic, you may decide that Instagram is the best place to build your brand by using a series of witty pictures with a strong call to action to make a purchase. Alternatively, you may decide to extend the reach of your brand by attempting to break into a new market, such as building a rapport with women, who comprise a large proportion of Pinterest users. Micro-blogging may be an ideal way to give busy business people the bite-sized content they need on their morning commute, while infographics provide visual punch to make a point instantly.
