Review your website, specifically how and where you use CTAs. As a general rule of thumb, I like to see a minimum of 3 CTAs on a page. Use a combination of suggestive copy with text links and graphics. If you use WordPress, it is fairly easy to create a text or, even better, clickable graphic CTA in a right column widget (try Canva.com).
Consider creating and using an “ad box” type CTA that is colorful and eye-catching. For added punch, use CTAs just after testimonials or reviews (i.e. social proof).
Be sure there is a CTA at the bottom of every page at your website including at the end of your blog posts. Both of these are places where people naturally look for the next thing to do! Maybe consider a big CTA graphic “bar.”
Again, do not make them think! Consider tools like Opt-in Monster (see below) to launch pop-up boxes, particularly “exit-intent” pop-ups. You may personally hate them like I do, but I can tell you from firsthand experience – THEY WORK! Remember to use CTAs regularly in your social media posts and within your print advertising (“Visit our website for…”).
