Did you ever wonder how some sites are able to tailor a message specifically to your city? You might have seen these in ads: “Albuquerque mom loses 50 lbs!” Hmm. How did the site know you live in Albuquerque?
The answer is geolocation based on the user’s IP address. And of course, geolocation can be useful beyond tailoring custom ad messages. The good news? Free geolocation functionality exists!
