"We have already worked with several companies in the search engine marketing industry.
We employed SUMO GmbH to optimise our Internet pages and have been very satisfied with their work so far. They have met all of our expectations and we have acquired numerous new clients.
When you decide to work with a search engine optimiser, it is very important to chose a competent and reputable company as a partner."
Klaus Kuenen, Deutsche Post AG

SUMO is a reliable business partner with excellent client management. The SUMO team is very motivated and commited to achieving their goals. We are extremely satisfied with their work so far."
Erik Siekmann, Blume 2000 New Media AG
"Our experience with SUMO GmbH is that of a reliable and professional company. From the very beginning they informed us quite clearly about what is and is not possible.
Such trustworthy co-operation is essential for search engine optimisation. When you add this to satisfactory results - perfect! This is why we soon extended our commitment considerably."
Elmar Schneiders, Bereich E-Business, DEVK Insurance
"Our expectations have been more than fulfilled. At the outset, we were very sceptical about whether search engine optimisation would be worthwhile for our company. We certainly do not have any reservations about it now.
Thanks to SUMO, our company has become visible in the Internet and our visitors are from our target market - this can be seen in the significant increase in orders.
At a time when the economy is struggling, search engine optimisation by SUMO GmbH has proven to be an extremely efficient marketing tool."
Georg Zens, FPS GmbH
