Of course, if you're going the paid ad route, you could also use Facebook and Google re-targeting to keep that awareness and interest level high. For example, if you've ever noticed after leaving a particular website, that you begin to see their ad everywhere, there's a particular reason for that. Especially if they've already entered your sales funnel, this is a very powerful way to get them to act.
Become an authority in your industry and/or region. If you're known far and wide for being an industry expert, you'll have prospects seeking you out rather than the other way around. Consider planning lunch and learn sessions or organizing webinars on a regular basis. As your brand recognition grows, you may even attract inbound links to your site which will benefit your SEO.
Have a clear call to action. Call to actions can be present in the headline text as well as the button text (example: “submit” vs. “download your free marketing guide”). There should be no question as to what next steps are necessary – tell your visitors exactly what you want them to do in big, bold text. For Kajabi, changing their button text from “See Plans and Pricing” to “Get Started Today” increased conversions by 252%!
