Strange keyword strings on real time report
Hey, since nobody has answered yet but you probably saw the answer in another thread. I'll just answer it from what I've read so far.
They are your email marketing campaigns. So for example, Mailchimp will show up like this and they add these numbers to links and visitors resulting from your EDM.
Hope that helps. To find out exactly which link is each number, you'd have to dig around GA a little more and your email marketing campaign (e.g. Mailchimp) analytics.
Hope that helps!
