Horrible page load speeds

Bubble has been making enhancements to their platform to address SEO performance. I'd say if you're using Bubble as a CMS where SEO is key, it might not be the right application of this tool (Webflow might be better for that). Bubble really shines as a rapid development tool for web apps. The pace of development with the power it offers is unmatched in the low/no-code space which makes it a great tool for rapid iteration on early stage concepts, or if you've got the know-how you can build pretty high-polish UIs and robust data structures and workflows to make it a great early stage, production ready app. I've seen it most often used by entrepreneurs looking to get some initial validation with a functional product (ie not just a clickable prototype) or by companies looking to build some internal tool and unburden dev/IT resources with creating one-off apps. tl;dr Bubble is great as a web app builder, just know what to use it for and how :)
