I'm wondering if this concept would work...
I love cheese, and sometimes find that websites don't have enough info about cheese. So I'm trying to help Google and GTM know that I have a significant interest in cheese.
I want to code an extension in FF that looks for a GTM container ID and injects data into that container that sends tags for cheese, cheese products, charcuterie, etc. And even injects data showing large purchases of cheese. This will save Google time, because otherwise I would have to rely on several weeks or months of searches about cheese. Instead, if every site I visit helps me express an interest in cheese, that would be great!
I would, of course, only use this extension myself, and never share such a thing. In the extension options, I would be able to select tags to share, just in case I end up with a similar interest for pine trees, marshmallows, or tomatoes.
Thoughts? Open to any suggestions here.
It's probably no use replacing values that are already in window.dataLayer. they will already have been reported. But you can take a look in there across several sites to see if you can find common ways those segments are reported, then just spam that on every site.
