The upsell, also called a one time offer or OTO, appears after the buyer pays. Because the card is on file, saying yes takes one click. Buyers are most open to a new offer right after they buy.
Sell one product per page. The logical sequence of offers matters more than the price increase between them.
Do it step by step
- Offer the next thing they need because of what they just bought.
- Headline: present the offer. Subheadline: justify why now.
- Use a yes button that restates the benefit and a no thanks link that names what they give up.
- Keep the page short. They already trust you.
