Half promoted website? It will never take off (4)
I believe the answer is:
kiwi
'half' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for kiwi that I've seen before include "apteryx" , "'Fruit, bird and NZ rugby player (4)'" , "New Zealand bird that does not fly" , "Chinese gooseberry" , "New Zealander's bird" .)
