I'd say the follow are the major areas of 'commercial search' or verticals. I may be missing a few in my haste: Jobs
Real Estate (Homes, commercial)
Investing
Computers, Electronics (Consumer goods and business)
Software (Packaged, developers, ASP, etc.)
Medicine (Doctors, Hospitals, Medication)
Professional (Lawyers, Accounting, Engineers, etc.)
Travel (Hotels, Airfare, Ground Transfer, Rentals)
Education (College, University)
Food
Vehicles
Clothing
Gifts
Sales Lead Generation (Industrial, commercial)
Generally, I'd say "local search" is about "local consumption": Something I pick up from a local business and consume in my hometown OR something I consume/use "when I arrive locally". It could also include goods/services I purchase for someone else's consumption at a distant location. I don't include in "local search" general consumer mass market products that ship from a remote location to my home "if only by chance or price".
Markets?
Chicago
Atlantic City
Los Angeles
Des Moines Iowa
Trenton NJ
Atlanta
Phoenix
Detroit
Any city population 25-75,000 anywhere.
Feel free to add any city/vertical for which you have information.
