Caller ID was listed as "Business". Their robo-caller did not even wait for my voice mail greeting to end. When the greeting stopped, their recording was already halfway through a message telling me how Google could improve my business.
They wanted me to press "1" to see if my business would "qualify" for their service. I would bet that everyone who presses "1" qualifies.
They gave me an option of pressing "2" to be "removed". They didn't say removed from what. Multiple contributors to 800notes.com have found that if you choose the removal option, the robo-caller knows that it reached a valid number, and the calls to you actually increase.
