I’ve not seen any mention before of Plausible in the forum. The issue you are probably facing with Bubble SPA is you need to add into your workflows something to do the pushState. Bubble SPA implementations won’t do a pushState out of the box.
Either bake it yourself like this History.pushState() - Web APIs | MDN
Some plugins might achieve the same like URL Router for Navigation Plugin | Bubble and [UPDATED v2.2.0] 😃 Sudsy Page router for SEO-friendly clean URLs! (by Tech-Tonic) (I’ve not used either - just a guess)
I’ve been wrestling with 1. Google Analytics adding to an already slow page load 2. Privacy management with Google, ie compliance with GDPR etc etc etc 3. Looking for a new plugin idea - Plausible might be my solution.
