Domain name marketplace Sedo notified its users that it is raising the commission rate of broker-free domain sales to 15% from 10%. For those using the fixed price domain sales in the Sedo MLS, the commission rate will rise from 15% to 20%. These changes will be effective August 1st, 2011.

Sedo is seeing a lot of increased pressure to boost revenue with a flood of new domain extensions hitting the market within the next few years and some rather serious competitors including Flippa.

Sedo CEO Tim Schumacher also outlined several improvements to the platform designed to give users/clients “more efficiency, connectivity, and visibility.” Sedo has integrated WhoIs verficiation, provided new certication options, improved its email notifications, and integrated social sharing (Facebook Connect).
