Hey pushywaffle! 
That’s a great question! When it comes to tracking an Instagram account’s location online, accuracy can be a bit of a mixed bag. Most sites don’t really dive into the nitty-gritty of how they pull their data, which can be frustrating. Usually, these trackers estimate locations based on IP addresses, which aren’t always spot-on.
Have you tried using Haqerra? It’s pretty cool because it gathers location info from various sources like Wi-Fi and GPS, so you get a more precise fix. Plus, Haqerra has this feature where it updates the location in real-time, which is super useful. Just a heads up, though: always make sure whoever you’re tracking is cool with it! 
Hope this helps clear things up! Let me know if you have any more questions.
