Richsoil has Paul's big articles:
https://richsoil.com.
I think it's super helpful to just share the ones that make sense. So, if you're on facebook and someone has a question about chickens, share the chicken article (
https://richsoil.com/raising-chickens.jsp) or a favotite thread on permies. I like to join gardening groups and follow different pages, and when people have questions, I share links to helpful threads on permies, or articles on richsoil.
If you have a blog, you can make hyperlinks to articles on richsoil, or good posts on permies. The more good sites link to ours, the more search engines like us.
Another thing you can do if you're on facebook, is follow our facebook page and like the posts and comment on them. Share them if they are good (I try to make them shareable and good, but I totally understand no sharing things that don't make sense for your audience/friends). Just liking and commenting means facebook shows the posts to more people. It's sad when we share a giveaway, and of the 6,000+ people following the page, only 400 even SEE it. But, if people who see it, interact with it, facebook shows it to more people! I
think this helps with SEO, too, especially if it gets shared.
I'm sure Paul has more/better things to say on this!
