Social media marketing and social media optimisation are broad labels. Ask what the work includes before treating either as a distinct guaranteed result.
Understand the common distinction
SMM often describes campaign activity and promotion. SMO often describes improving profiles, content and sharing journeys. Suppliers use the terms differently, so the written deliverables matter more than the acronym.
Connect the responsibilities
Research, creative, publishing, community response and advertising may involve different owners and costs. A clear profile supports a campaign, while a campaign needs a destination and response process.
Choose useful measures
Review appropriate distribution metrics alongside relevant website activity and verified actions. Neither term establishes a Google ranking benefit or a guaranteed audience size. Ask how the proposal fits the actual business task.
Official guidance: Google search context.
