Before seeking more (subscribers, audience, fans), seek flow. This is something I bring up a lot through my Email Guidance offering.
Is your website set up in a way that pulls people in? Or is it a bunch of links to third party platforms that seek only to monetize and collect data from your fans?
Does your sales page include comforting and informative videos about what you offer? Or do you only post those sorts of videos on Instagram for just 3% of your followers to see?
Does your store have more than one item (this one from Laura Kidd) in stock?
We want to expand and grow our audience, but stepping back and making subtle changes to our current operations might be a better place to start
