Emails is the obvious one, sendingcontent that might address any hesitations they might have with continuing with their progress towards the action. Other nurturing might depend on who you have available and what you are trying to get them to do. Have a salesperson? Get them to call and discuss the product/service (they don’t have to mention that you know the customer has visited the page!). Offer a demo, perhaps? Send them to blog posts that reinforce your message.
