Mike Blumenthal spotted Google's test for new car leads on its search engine in the San Francisco market. He tells us that the product, dubbed Google Comparison Ads for Autos, allows customers to anonymously request quotes for inventory in stock. The results are focused on "lower sales funnel queries." Blumenthal takes us through the process, provides a few screen shots to demonstrate the point, and includes a video from PGC Digital marketing explaining the program.
