Search Engine Optimization
Last century, businesses used the Yellow Pages, but this century search engines such as Google and Bing funnel customers to businesses who can help them.
Advertise on Google and Bing using Pay Per Click (PPC). Your ad shows in response to a potential customer's search, and you pay each time a potential customer clicks on your ad.
Chances are high that a large portion of your potential customers spend a lot of time on Facebook, so it is important to examine how Facebook can help you grow your business.
