First - how are 3rd party leads obtained? Typically from a clever SEM campaign offering "secret pricing" or "clearance prices", etc, which then takes the shopper to a landing page where they must submit their info to get the "best price" etc...
Second - that lead is then sold or shared with multiple dealers, who all call/email the shopper around the same time.
Third - your sales reps often are met with a hostile reaction as the prospects are often unsure how you got their contact info, and they are aggravated at all of the calls and emails they are receiving.
The leads are difficult to close with all of the competition, and are also hard to sell with a good gross/unit as a result. With all of that said, there is a COST TO YOUR LABOR in working these leads, as well as an cost to the loss of motivation of your sales reps who are working hard and seeing little results with these leads.
With all of that said, you should be calculating your ROI on these leads to include a labor cost (I am showing this at the upcoming Digital Dealer). Closing rate will typically be no higher than 6-8% on average, and gpu lower than average. If you are a dealership that is struggling with enough folks to work your leads, focus your time on your BEST leads which make you the most money, and use a customized, shortened process for your 3rd party leads.
As for GM Handraiser leads - we have sold a few, but most are useless. Remember, they typically gave their info for a free hat, shirt, etc, and then GM tells us they are "ready to buy" shoppers. Right...
