Can you track drones online?
As far as the tracking on aviation websites goes, no you cannot, at least not with the drones or UAVs available for leisure activities.

In order to track these devices they would either need to be equipped with FLARM or a transponder with Mode-S, which again would require a registration.

Unless you have fitted a GPS transceiver to your UAV which offers online tracking via the vendor's website, you will be unable to track UAVs.
