Business related offers with an impressive squeeze page that forwards to sales page after optin. Followup offers to recover ad costs over time. Buy 50 to 100 clicks from different sellers to see who has a list that best fits your offer. Then scale from there buying more clicks from the sellers you get the best results from.
Harrison pretty much knocked it outta the park...i would add, to make your squeeze page congruent with the offer, this pre-frames the lead for whats on the offer page. your follow up sequence should not only sell but also focus on testimonials, features and benefits of the offer.
