This page would normally contain your business references.
A neat trick on this sort of page is to link to a (or a couple of) jpeg (image) files which could contain a signed reference letter from someone such as a bank, chamber of commerce, union etc. on that source's letterhead. That way your site visitor can display and/or print the letter and have an immediate "warm and fuzzy" experience regarding your legitamacy. Particularly useful if you are trying to sell something directly online!
