Accuracy

IP to Location

IP to location technology is a method of using an IP address to determine visitor location by matching it against an IP to location database.

Non-Intrusive

Geolify utilizes IP to location technology to obtain visitor geo location data hence making the process of geo targeting visitors ‘non-intrusive’ i.e. not requiring visitors to acknowledge their location is being tracked.

Accuracy

Out standard accuracy service has an approximate accuracy below in the United States and other major countries:

-          Country level: 99%

-          State-Region level: 85%

-          City level: 75%

Our high accuracy service which will be released shortly at a higher cost utilizes industry leading enterprise level IP to location technology thus providing far better accuracies worldwide compared to our standard service. This high accuracy service is perfect for more granular city level targeting or if your website consists of mainly mobile visitors.

It is important to realize this accuracy when using IP to location technology and note that it cannot be used to pin point the exact location of a visitor’s location similar to a GPS sensor.

Mobile Devices

Mobile devices unlike fixed desktop routers are harder to locate via their IP addresses due to them being passed through cell towers which may be located some distance away from the mobile phone itself.

Hence it is important to note accuracy on a city level for mobile devices may be compromised.

Content Delivery Networks (CDNs)

If your website is served through a CDN, Geolify will request from the CDN the true client IP address to ensure the location data obtained is not of the CDN but the actual visitor. A list of headers we request for can be found below:

HTTP_CLIENT_IP

HTTP_X_FORWARDED_FOR

HTTP_X_FORWARDED

HTTP_X_CLUSTER_CLIENT_IP
