When you allow geotagging with an image, you are allowing a website to see the location information for a photo/video you've taken.
Be cautious when providing this metadata. You might just wind up on http://iknowwhereyourcatlives.com/.
Every photo on this site was created and uploaded with the locational metadata intact by the original owners with an estimated 7.8 meters accuracy. It's scary that you might give random strangers access into your house. Turn off your geotags.
