The latest release of maps.google.com has greatly improved home web pages for local business listings. Previously, there were a lot of errors. For example, my son attends the University of Central Florida in Orlando. Previously, the website listed for UCF was the University of Toronto!
Now it's correct: http://maps.google.com/maps?f=l&hl=en&q=university+of+central+florida&near=orlando+fl&layer=&ie=UTF8&amp;z=11&ll=28.651428,-81.377106&spn=0.284412,0.63858&om=1&iwloc=A
Google appears to have significantly improved their ability to find the right web site for a local business listing. I have yet to find one that is blatantly wrong.
One small step for better business listings.
