I have an online platform designed for use by baby booms & senior citizens. However since (I think?) they don't typically spend as much time online as the younger generations, then how or where can I go to effectively market to this audience online? Offline marketing suggestions are less relevant at this time, but always valued/appreciated!
I'd make your No. 1 priority growing an email list. It's almost *always* important for growing communities, but for this particular target market that might not be on social as much as the rest of us, it's even more important. Create a valuable freebie to encourage them to opt in, and then you can go to them where you know they're already hanging out: their inbox.
