You can't. You can only share either individual activities links or your profile link, but people have to log in to view more than the several latest activities via your profile. 

Thanks Jana-S. So, I know I can generate a weekly report that has links to the activities of that week, but without signing in I guess my total activity feed would be unavailable. 

Correct, complete feed is only for users. 

There’s one more option I haven't mentioned, a website/blog widget - embedding recent activities, but tbh I’m not sure how many activities exactly get displayed that way; here's more details:

I have a club activity widget embedded in the club’s website homepage, and it only shows the most recent five public activities by club members. So I’d guess a personal activity widget has the same limit.
