Don’t let the visitor “work hard” to buy. Don’t be “in his way.”
All through your web page (sales page) don’t forget to ask “Have you made a decision already?” And give them a one-click way to buy.
To grab their attention again and again.
When showing the visitor to your web page a call to action that is always visible (floating, attached to the top or bottom, etc.), don’t just “leave it there,” but change it over and over again. You can make it disappear and then reappear, change its shape, color, change its position, add a countdown, etc. The triggers can be time, scrolling, clicking, etc.
To better target ad messages to what the visitor is seeing or reading.
Have an ad that floats and stays with the visitor as he is scrolling the web page. This floating ad changes based on the text the visitor is currently reading or the graphic or video he is watching. This way each ad and call to action can be very particular to the state of mind of the visitor at any given time.
