Multiple visits with 100% bounce from 1e100.net

[jez000]

Hi guys, I'm seeing multiple visits via an Adwords campaign from domain 1e100.net. I've found that this domain is related to Google's safe browsing feature, and thought perhaps it's Google checking that my landing page is not a phishing site, but multiple visits in the one day? I've updated my destination url a couple times, but certainly not 10+ times. These visits are showing up as a bounce - they come in to my landing page, do nothing, then exit. Interestingly, when I break down the visit by originating country, they come from the US, whereas my paid search campaign is limited to Australia only. Would appreciate any thoughts Cheers, Jez

Nothing to worry about

"1e100.net is a Google-owned domain name used to identify the servers in our network.

Following standard industry practice, we make sure each IP address has a corresponding hostname. In October 2009, we started using a single domain name to identify our servers across all Google products, rather than use different product domains such as youtube.com, blogger.com, and google.com. We did this for two reasons: first, to keep things simpler, and second, to proactively improve security by protecting against potential threats such as cross-site scripting attacks.

Most typical Internet users will never see 1e100.net, but we picked a Googley name for it just in case (1e100 is scientific notation for 1 googol)."

I got this one yesterday as well. All of the sudden I saw 200-300 visitors in the live screen (live view Google analytics). When checking more in-depth all these 1e100.net records were tracked as different keywords (about 30+ different keywords) from organic search.

I see the explanation from Google, but I don't understand why they do this (is it just normal crawlers) and why they don't filter it out of Analytics?
