Malinda, we have long taken the stance that it is the quality of fans that is critical for success, not the quantity. The top priority for an auto dealer should be to build their number of in-market fans and followers. Not only do in-market fans have the potential to become a customer, but their social network is going to be concentrated around where they live. So if they live in your market, so do the majority of their friends. This means there is a far greater chance your content will be relevant to their audience, and so they will be more likely to share or re-tweet your content. Since your fans’ friends tend to be in your market, their friends (friends of friends of fans) will also tend to be within your market, again, meaning a better opportunity for sharing relevant content. This is where the viral effect of social media really comes into play. Your content posts to even a small, local, quality audience can have a large effect, because it’s not simply the size of your audience that affects your reach, but the size of your local audiences’ reach beyond your immediate audience.
So if you are planning to offer an incentive to Like your page - use incentives that appeal to your local market. How about a gift certificate to a local restaurant, or local event? Another possibility is to donate to a local charity or non profit (the high school booster club?). Again, by choosing local organizations you will be more likely to appeal to people in-market. The alternative is giving away items that have mass appeal (how many iPad giveways can there be?) where you will get a lot more people to respond, but you are not targeting people that are in-market or who have the potential of doing business with you.
Building fans that are out of market means that promotions from your business are not relevant, to them and most of their friends, so the result is no sharing, no clicking, no response. Dealers who have this large fragmented audience only see clicks and sharing when they post generic content, such as a photo of a polar bear. While the polar bear may be cute, and may incite some fans to click or share, these are not actions that are going to generate new customers.
