Just because your site is well-designed doesn't mean that it's effective.
There's one simple reason for this: most people fail to understand that websites are processes.
Websites are processes and start way before people come to your website and only end with clients buying your service or product.
It's no longer about optimizing your websites for SEO and hoping for the best. It's about optimizing your presence across the web and in the real world as well. It's about building bridges between your efforts, online and offline.
Take time to carefully craft your value proposition. Help people to easily get how you can help them. Make sure that your landing page works. A value proposition, a deep dive into your client's big, expensive problem and a call to action are essential. And finally, provide means to stay in contact. If you use an email list, don't send these spammy newsletters. Personalize. Give value. A lot.
