I ignored this post initially, thinking the effort itself is misguided (aka, not at all necessary) and a gran waste of time. I think G understands very well who is who and adapts to their behavior very quickly.
But eWhisper's someone I respect a great deal. eW, is this a common practice for you?
I assume you're blocking IPs to raise CTR and/or ROAS, but I know IPs for many competitors aren't the end all they used to be - mobile, travel, multi-devices, phones / tablets using wi-fi... some internet access being consolidated on non-geo specific IPs (like my central Florida access providers shows a Miami IP address regarding geo location... I can't help but think this is a huge time suck, and is also likely blocking people you don't want to block.
Perhaps this is an uber competitive niche [or your intended geo targets are someplace fraught with issues (outside of north america)] and you've got every other base covered completely... no accusation meant by this, but often when i see ppc folks chasing something weird like this, from experience in reviewing their efforts, they often have huge issues with their PPC on many other fronts, like keyword matching, and other basic stuff.
yes, it sounds like i'm saying you're chasing something stupid, i was thinking that before i posted, but now i'm wondering if i'm the idiot. :-)
eW, clue me in?
