Because Bing is a smaller search engine when compared to Google, there’s less competition, costs per click are usually lower, and your overall campaign costs are lower too. You can target consumers who frequent Bing, Yahoo and AOL in preference to Google, extending your reach into new audiences and consumer groups.
Bing ads offer much the same type of targeting as Google AdWords, but due to arguably better placement on the page, they receive a higher click through rate.
Bing is often overlooked by many online marketers, as well as by many small businesses. This gives your business a competitive edge over the market place, because you’re tapping into a new and underappreciated consumer base.
