As an officer of Central Austin Toastmasters, I use Meetup to advertise my club and welcome new guests. Meetup allows me to set 15 keywords that best describe my club. It also lets you (a Meetup member) set keywords that describe your interests. Meetup uses your keywords to recommend groups that would interest you.
My goal is to attract more Meetup members so that more will visit my Toastmasters club. Hence, I should select keywords that are not only relevant to my club, but will also likely coincide with your interests.
Which 15 keywords should I use to attract more members?
I wrote a simple program to help me decide on these keywords.
