Geolocation - City dimension precision?

Hello bucketers :-),

I'm trying to use geolocation targeting for some major cities in Czech republic. I've set up several buckets for "Czech Republic" (country-level), for "Prague" (city-level) and for "Ceske Budejovice" (city-level) visitors. For these buckets I've created some simple targeting just by appending a paragraph with "Hello to Prague".

The problem is that nobody of my Prague friends (no big sample, just a dozen of them), who visited the page, saw the city-level greeting. But everybody saw the country-level greeting "Hello Czechs".

When I was creating the buckets, it suggested me the precise city names, so I think that they exist in the geo database. Do you know anything about BTBucket's precision of city-level recognition?

Do you have similar problems with the geo precision in some other countries?

Thanks

Pavel Jasek

Hi Pavel,

Our GeoIP solution provider is MaxMind. We monthly update the GeoIP database.

The accuracy for country level is 99.5%. However, in the city level it depends of each country. For example, in the US the accuracy reaches 79%.

Please, visit the link below to check your country accuracy:

Hey there,

Any plans to upgrade your systems to leverage the more accurate MaxMind - GeoIP City database? I like your solution and am trying to convince a large client to use it for geo-targeting to its web visitors. Accuracy on a city level is very important to us, even if its only a few percentage points. The GeoIP City database is 83% accurate at city level. I'd love to discuss this with someone from your company.

Thx.

Mark,
MaxMind seemed to be the best option for us at the time.
Please email andre @ btbuckets. com in order for us to discuss this.

Thanks,
Andre

Hi Mark - what countries are you expecting to target? Some countries have a city targeting accuracy above the total average: www.maxmind.com/app/city_accuracy.

We are also upgrading from the Maxmind GeoLite database to the GeoIP City Database.
