Hmm good question. On the one hand, I work for a very large company as a software engineer at the moment, and the team I'm on handles their public website. So anything on the site home page (or site wide) would count. I've also worked with companies who have had other large corporations as clients, and have worked on things like CRO tests and full website redesigns for them. So any one of the things I've worked on in a professional capacity could count.

But at the same time, my personal websites and videos have had a pretty big impact too, with a fair few of the latter reaching over a million views, and a few articles on the former getting covered by all kinds of news publications and getting a good number of views there too.

So it's hard to be sure.
