It appears to me that type in traffic may help you rank for your brand name, but not for the products you sell.
I've been watching the SERPs for "business widgets". There are lots of big brands that sell consumer grade versions. There are also a couple companies that specialize in high volume specifically for businesses that all the businesses use. I'd expect the SERPs to be:
Instead the SERPs are:
business<storetype>.com (the only national consumer brand that makes the rankings because their name matches one of the two words)
The interesting thing to me is the "related searches" section at the bottom of the SERPs has all right. It has a mix of consumer and business brands that I would expect to see in the main results.
Unless your brand name matches what you sell, you are out of luck from any boost from type in traffic. God help you if you are non-consumer facing and sell only high volume to a limited number of customers.
