Here I am, an online marketer, and it just dawned on me. Over the last several days, I've been on a few dozen web sites, and I've been stalked by recurring Spyfu banner ads.
I just realized I must've visited Spyfu or one of its affiliates, and I'm now the victim of remarketing (see Google Ad Innovations - Remarketing for an explanation).
I'm curious if others are taking note of this technique, and would also like to hear from those who employ remarketing. Is it working?
