the correlation between website traffic and sales is absolutely NOT 1:1 (it's probably not in most cases even 100:1). What a dealership website does that traditional advertising, radio, television is answer the following questions that all car customers are asking:
1.) Do they have what I want?
2.) Do they have what I want at a price I can afford?
3.) Do they have what I want at a price I can afford in a color I like?
There really is no other reason to visit a dealership website unless you are at least somewhat interested in buying a product or service from that dealership. I mean let's face it our funny pictures of cats are nothing when compared to fan pages on facebook, our blogs REALLY aren't all that interesting, and people really aren't looking to see if any of their friends work at XYZ dealership (staff page).
Is Dealership Website traffic going to be a definitive determiner of expected sales, NO! But as a dealer whose advertising is heavily invested in Digital I can tell you months where my group has over 1 million page views are typically much more successful sales months than the ones where the traffic was incrementally smaller.
Keep telling yourselves there's no correlation between Dealer Website traffic and sales and I'll keep laughing while I hand you your ass every month without fail.</story>
