Every now and then I come across a website that impresses me by how they use simple technology in a unique and interesting way. Microsoft Hohm does this by using IP / location data to show visitors a dynamic and personalized message. Technologically simple, yet very innovative and an interesting marketing approach to increase conversions through personalized Calls to Action (CTA).
Check out this screenshot showing my visit to the Microsoft Hohm website from my office in Providence, RI. Very cool and a great way to engage website visitors.
