風俗店 is a broader term that can include non-sexual adult entertainment such as host clubs or strip theaters, while 性風俗店 explicitly refers to businesses providing sexual services.
Compound of 性 (sei, 'sex') + 風俗 (fūzoku, 'public morals; sex industry') + 店 (ten, 'shop'). The term likely emerged to distinguish explicitly sexual businesses from the broader 風俗店 category.
