Recommendation, Advice
noun, verbal noun
If 薦める is "to recommend," then the noun version would be a recommendation or some advice. This generally refers to a recommendation of a person or thing, not an action.
すすめ
The reading comes from 薦める. Might I make the recommendation to learn that word first?
そのスリッパは私のお薦めです。
Those slippers are my recommendation.
