Comparing e-Sourcing vendors’ traffic ranking (Alexa)

Which company is the most popular eSourcing vendor?

I’ve decided to look at Alexa and compare traffic ranking. Below is the outcome.

To be honest, first hand, I’ve been surprised (a bit), but if you take into account that some of those Vendors have different platforms available for their customer, instead of a unique one (as Eutilia, for example) you better understand the result.

Alexa traffic Rank (8-11-2006)

1. Ariba: 138.186
2. Eutilia: 158.648
3. SourcingParts: 297,410
4. Emptoris: 283.457
5. Perfect Commerce: 385.324
6. VerticalNet: 586,146
7. Procuri: 605.318
8. Frictionless: 845.304
9. Portum: 1.211.656
10. Synertrade: 1.578.132
11. Iasta: 1.997.469
    
12. BravoSolution(fr): 4.692.900
13. ScanMarket: No Data

Any other Vendor I should include in this ranking?
