On Google?! Sorry but they forbid all marijuana advertising so PPC is really a long shot there . you might try Mantis . you can do it on FB IF you don’t reveal marijuana til the LP . but looking for investors there? If you want investors, you gotta go where investors go! They aren’t googling something to throw their money at . USAToday Network has a great mari friendly platform & includes an investor marketing component but it’s not cheap. Might be worth a call to a rep tho. You can google that!
