My template incorporates everything Bubble has to offer for SEO and makes best practice use of them all, plus some more complicated approaches to incorporate structured data.
This template also has a powerful CMS
Basics of Bubble SEO is that they offer the ability to add dynamic data on the page element for SEO/FB Title, Description, Image and Header
They also provide Header Tags for Text Elements
As well as Link elements
SEO for the app as a whole and site maps in the settings tab under the SEO Tab
As well as Rich Text Editor Plugin to get more links in the body of text (useful for outbound links)
It is then up to you to make use of all those according to SEO best practices in general, so might need to do some research outside of the Bubble ecosystem into SEO.
If you are looking just to integrate a blog for content and SEO benefits, my template is the best thing out there for it and saves dozens of hours in development time, doesn’t require complex integration of 3rd party site or the extra cost of hosting a 3rd party site.
