I've been on Fetlife for a long time, but it was more personal. That has changed a bit as I work for Sanctuary LAX, DomCon, and The Dungeon Store.
I'm posting a link of the day there for The Dungeon Store every week day and posting press releases on my journal. The trick with links for photo posts is to post the link in the comments. For example, post a pic of my art, and comment with "to follow up, you can find it on etsy at..."
Fetlife is more about engagement. That's really going to be the challenge as I do more with TheDungeonStore.com. It's going to be less about the posts, and more about getting personal.
I've noticed certain circles too. For example, there's a lot who just like to post bootlegged pics, which is why a lot of webmasters hate Fet. There's a lot of active groups. So a profile could look very quiet, while in reality they are actively surfing discussions in groups. Fetlife has also become essential when getting the word out about events, like a kinky Facebook.

Best of luck to you!
