What Seriously Simple Podcasting is
Seriously Simple Podcasting is a WordPress plugin for publishing podcast episodes from WordPress when paired with Castos hosting. Publishers can send episodes from the WordPress editor to Apple Podcasts, Spotify, and major podcast directories, and control the podcast RSS feed there. One WordPress site can manage multiple podcasts, each with a separate feed. Episode-level statistics show which episodes perform well. Listed free add-ons include Genesis support, embedded transcripts, media player customization, and featured speaker boxes. The plugin is open source, and its page invites issue reports and pull requests. Castos says its hosting stores audio and video on a CDN-powered platform, and its plans include triple-redundant data backup with cross-site retention and a global content delivery network. Castos also lists integrations including Zapier, MemberSpace, Shopify, Elementor, Descript, Kit, Stripe, PayPal, and MemberPress.
