I don't think increasing their revenue per search is going to be small potatoes but I agree that getting that email and connecting it with purchase data is going to be hugely valuable. What we're both talking about are just two sides of the same coin. The goal is maximizing the total lifetime value of the customer. One approach is by increasing the revenue per transaction and the second is increasing the number of transactions per customer. (Third would be increasing referrals per customer but that probably won't factor in as much, I suspect.)
