Linking Buttons on Homepage to Collection Pages / List

Hi ! I have a question about a) linking my collection pages to buttons on my home page and b) linking google analytics to this collection. a) I can’t figure out how to link my collection to buttons (marked locations) that I have on a map on my homepage ( ( I used this tutorial: https://www.youtube.com/watch?v=VqSEvzzLoVQ). What I want is: Click a button on my homepage, and get directed to one of my collection pages. Click another button, another page, and so on. It seems to me like I’m missing something obvious, but I have been struggling with this for over a week now and I can’t figure it out.

With that, does anybody have experience with tracking collection pages with google analytics? I put the custom code in my collection. Is that enough? At this point I am thinking I might just make actual pages, and lose the collection. But I also feel like that would be counterproductive.
