You can link Google Keep Notes to other notes by copying the URL from one note and pasting it into another.
Here’s an example link to a Google Keep doc. If you follow it, it opens the note.

You can also link with searches. I use a Note Number System that makes my notes sortable, searchable, and linkable.
Here is a link that performs a search for “nn2403”. Using my numbering system this brings up every note I wrote in March of 2024.
