Is this new or have I just missed it? Have you tried Google Analytics Live view? It's amazing, or I think it is anyway. Wow, talk about being obsessed - you can watch people come and go, where they came from and what they searched for Live. Just makes you think, if they can show that to us, what Google uses for itself to track web browsing habits. I mean I guess what we get is a civilian type affair compared to their military grade type tools.
I am sure we do. I think the "Real-Time" analytics has been around for around 2 1/2 years now. The first year they released it to their "preferred" clients, those big domains that get preferential treatment mainly because of their huge ad spends. But for people like you and me, I think it has been around a little over a year. And yes Google knows all. Think about this, you are only talking web traffic, think how much data they store with smart phones now, every time you use Google maps they know who you are and where you are. Its crazy what they have access to. Cheers
