Prevent Fraud, Password Sharing, and Abuse of Service

Your customer’s billing information says he’s Clark Kent, who lives in Smallville in the United States. But, he wants to purchase $100,000 worth of electronics on your website from an IP address located in the Ukraine. Should you fulfill his order or flag it for further investigation as potential fraud? Hey, Superman can order whatever he wants!

That’s where Melissa’s Global IP comes in.

Global IP reveals the geolocation data of your customers. You can take that data and see if it matches their billing and contact information in your databases. For example, Global IP API can be used to determine the location of the shopper is in the Ukraine, but the billing address is in Dallas, Texas – this could signal a fraudulent transaction. Armed with this information, you can decide to block entire locations if necessary.

Improve User Experience

If your company has a worldwide presence, you may need to serve multiple international pages, each one with currency and language specific to the country of origin. You wouldn’t want your U.S. customers to land on a German language page, for example—unless they spoke the language, they’d be confused and likely abandon their purchase.

That’s where Global IP comes in.

By knowing where your customers are, Global IP helps provide an improved global experience where you can route visitors to the best version of your website, in a language that literally speaks to each customer. It also allows for currency matching for specific IPs or locations.

Ever wonder how Google knows where you are when you run a search and shows you relevant local ads in your results? IP Geolocation—that’s how! With Global IP, you can harness this application as well.

Global IP can help you power local search, as well as run geotargeted advertising campaigns by finding the visitor’s IP address to determine their location. From there, the IP is matched and mapped to its country, state, and postal code so your website can show search results and tailor ads to a visitor’s location. By reaching customers locally, you can deliver the most relevant results to each individual. Target to specific locations or languages, or ensure that customers closest to your physical stores get personalized ads delivered to their mobile phones.

You can also use IP geolocation to segment mailing lists based on where prospects or current clients live, work, or shop. When your customers open emails or browse your website, their IP address is stored in a database that you can access to see where they are physically. IP address data can tell you the country, state, and even postal code. From there, you just look at the data, and use this information to create location segments based on engagement, interest, or proximity.

With Global IP, you can take your omnichannel marketing to the next level.
