For our website, we don't use any SEO wizardry. We just submitted our sitemap to Google Search Console and made sure our page excerpts look OK with SEOPress. Just the bare minimum, regular stuff, and we do this for all sites we build. It's done in just a couple of minutes.
But we love audio recording and sound design, and that page has some useful info on how we do mobile podcast recording and post production. Also, it has some tips on how to get you podcast to an actual audience.
Apparently, Google rewards insightful content written with true passion, and we think that's a wonderful thing for the quality of the internet.
