My Anvil/SaaS app is currently invisible to Google search. Meredydd suggested that I create a “home page” on WordPress with a link to my app. He had also mentioned on an earlier occasion (Sorry Meredydd, I’m NOT throwing you under the proverbial bus ) that Anvil would have some additional functionality regarding SEO for Anvil apps, but I haven’t heard anything about it since then.
