During the last two years, Forrester evaluated the usability of 60 business-to-business (B2B) sites. We found much poor usability, especially when compared with business-to-consumer (B2C) sites. B2B sites received their lowest scores on our navigation criteria and were particularly hampered by illegible text. To improve their sites, B2B site managers need to learn from consumer sites and focus on the usability needs of their target customers.
