I believe the answer is:
'www' is the definition.
I can't tell whether this defines the answer.
'tent org?' is the wordplay.
'tent' becomes 'camp' (I've seen this in another clue).
'org?' becomes 'site' (I can't explain this - if you can you should give a lot more credence to this answer).
Can you help me to learn more?
(Other definitions for campsite that I've seen before include "for temporary accommodation" , "Ground for tents" , "Location for pitching tents" .)
