A step-up for a poet (9)

I believe the answer is:

promotion

'a step-up' is the definition.

'for a poet' is the wordplay.
'for' becomes 'pro' (as in being 'pro' or in favour of something).
'a poet' becomes 'motion' (former Poet Laureate Andrew Motion).
'pro'+'motion'='PROMOTION'

(Other definitions for promotion that I've seen before include "that should result in more money" , "sales campaign" , "Step up" , "movement?" , "Publicity campaign" .)

I've seen this clue in the Evening Standard.
