If you know your target audience, you might also know the general list of their beliefs and prior assumptions. It would be useful to learn the exact ones for each visitor.
When a visitor comes to your sales page, immediately show them a pop-up with a list of these beliefs and assumptions, and ask them to choose the ones they identify the most with. Based on their answer you then display slightly different sales page – emphasizing the relevant sections to address these – to each visitor.
In each situation, there is a different optimal time for an opt in pop up to be displayed. These are influenced by many parameters like who is the audience seeing this, how long is the content, what time of day, etc.
Have an option in your pop up management software to request a test where the pop-up will be displayed at random intervals. The more conversions you have for some of the times and the less for other the system will start showing the better ones more and drop the worst performing ones.
When the recipient opens their post box, the pop-up will stand out and grab their attention. Because it’s unique and playful, they will probably not through it away and also show it to others.
Print your advertising on the paper, and have pop up boxes made from it using folding and rubber bands. Then distribute it to post boxes in your business’ local area. It should be packed flat for distribution and slid into the post box, where it will pop up (partially or fully depending on the size of the post box), and wait to be discovered.
Help you remember the what and who of a book that is complex or you continue reading after a long break.
Have an option in ebook readers to turn on a layer of hyperlinks. These should be available to link characters and events mentioned to their origin in the book, so you can click on such a link, and it will either take you to the source so you can catch up again, or pop up a window with the original text so you can take a look, close it, and continue reading.
Help convert the ones who are just a step before buying.
When a visitor seems to be interested in an item (he spent more than average time on that page, scrolling back and forward reading, etc.), but then seemed to not buy the item and move on to something else (still on your website), you can pop up a one time offer that has a very short time limit (one minute should be more than enough.) It might say something like this: “Get XYZ for $79 instead of the usual $139 price. This offer is only good if you add it to your cart within the next 00:48 seconds.” (The time is an active countdown.) Once it’s in the cart, it should have a small text saying that the discount is only valid if they buy it during their current visit. This will help keep them from abandoning the cart and not finishing the purchase.
