This community is public. I added a new introduction category which you can use to promote your stuff. I'll keep the post up for as long as you're in the community or forever if I forget ๐คช You can do crazy long form posts if you like. These posts are searchable in Google and are pretty well search engine optimized as far as I can tell.
I also made the insights category available to everyone. You can use it as a place to write an interesting article on your topic. We can add questions in the comments and you can keep improving or editing it to your liking. You can add a link to your community in the article, and again, people will be able to find it on the internet. You can even sometimes repost cool posts from your private community so they become public and searchable.
If this idea doesn't get any traction after a couple of weeks, I'll just scrap it ๐
โ ๏ธ Again: Pitch your stuff in an introduction post, using the ๐ค introduction category. Use the ๐ก insights category for teaching us something that is tied to your community.
And if you're still not sure, have a look at the spam archive or DM me.
