Sweeps: iPhone / electronics
'Win the new iPhone' SOI sweepstakes affiliate sub-vertical.
iPhone (and other consumer-electronics) sweepstakes are an evergreen SOI affiliate sub-vertical, refreshed each Apple product launch. Same SOI economics as gift-card but with seasonal spike on launch dates. CPL $1.80–$3.20. Compliance is moderate — CAN-SPAM and TCPA exposure on the post-lead email/SMS programs is what regulators actually go after, not the affiliate creative.
Example
iPhone-sweepstakes SOI at $2.80 CPL spikes 4× on the day-of iPhone launch each September — operator queues 60 days of ad creative in advance to capture the spike.
