Geo-targeting accuracy numbers

I dug into my stats and ran a some calculations on the accuracy of 5 PPC networks on a 24 hour period starting Dec 20-Dec 21. All networks were set up to Geo-target the same country (US). Clicks in US versus international clicks were counted to show the accuracy of the PPC engine's Geo-targeting algos. Here are the results:




According to my data Yahoo had the most accurate targeting, just barely. All 3 of the main networks were very close and you can see a pretty large drop off with some 2nd tier networks.

 

Interesting, thanks for posting it. Do you mind me asking what you have monitoring the countries on your end?

 

Great work!! I love research! Rep worthy!

 

Its a custom script that parses the logs and checks the IPs again a geo-database.

 

Sweet, so you'd be pretty confident of the accuracy. Cheers

 

I do geo-target with Google some days from my websites and feel that it is not as accurate as it should be. Some days I have more unique visitors from a same little tiny town than NYC. I have some 'no-sense' days....

 

By the way, what service did you use to determine the visitors' actual locations afterward?

Um, why did you copy my post?

 

Maybe he doesn't do too well with english

 

Yeah I guess not - I see after a little digging, that most of his other posts are exact word for word copies of previous replies in the thread he is replying to.

What is the point of that? Perhaps "he" is an automated spambot just trying to boost "his" post count before dropping his URL all through DP forums?

 

Since every network or program uses a different database for keyword targeting, there are going to be hits and misses when you geo-target and when they geo-target. Just a fact of the net.

 

Did you account for "AOL" users?

AOL users cannot be geo-ip targeted and will always appear to be "outside of region"
