Newsfeed Personalization

Good morning, everyone,

In my app, there is a signup/in for sellers and another for buyers.

On one side sellers post their products and add keywords (thanks to the multiple input tool)

I would like to be able to propose a personalized news feed to the buyers according to their point of interests so that they can receive the right product corresponding to their needs.

For the moment I can’t categorize them or even send them content directly on Bubble.
I only take needs on Typeform which allows me to have an excel giving me the data for each buyer but it remains very simplistic and not sustainable.

I didn’t find a tutorial and I have a lot of difficulty using the data part or starting to do advanced things with bubble.

If someone could help me, I’d be happy to be guided.
