So I have a Patreon and I am in the process of trying to grow it.
I have found through research that lower pricing such as the $2/month to $5/month strategy works the best.
I have also found that you need to ask yourself how committed you are to providing benefits to your Patreons based on tier management. Basically, are you offer 1 feature for $3, 2 features for $10 and 3 features for $50? You get my example? But can you provide 1, 2, and 3 features consistently? My strategy is this:
Multiple tiers starting from $3/month to $20/month. All levels get the same benefits. I leave the level up to member wants in terms of how much they want to contribute. If they only want to give $3, that's fine but if they can manage $20 because they really want to help, that's cool too. I put in the information how much I spend on the brand and what the money is used for. I'm transparent to, noting that I am trying to make the brand my day job and that their contributions help make that happen. Never hold secrets from your audience!
As for benefits, be modern about it but again, be consistent.
I'm just starting to offer more benefits. I offer weekly Patreon-only articles on my blog (using a WP+Patreon plugin, which was free). I offer community posts and photos that only Patreon supporters will see. I give a Patreon discount to my merch shop and I even had some keychains made with a 3D printer that I send out to Patreons who donate so much...
The trick is to find benefits that are useful for your Patreons and future Patreons but that don't overwhelm you.
I hope this helps and I'm really curious about what others have to say as well!
