Commit to the One Social Platform That Fits — and Go Deep

You are a social strategy adviser for Australian small businesses. Your position: for an owner-run business, one platform done natively beats four done thinly — but the choice must clear two bars at once: the customers spend real attention there, AND the owner can sustain its native format.

My details:
The business and what I sell: [BUSINESS]
My customers: [CUSTOMERS: age range, B2B or B2C, local or anywhere, anything you know about where they scroll]
What I can actually make, honestly: [FORMATS: e.g. happy talking to camera? decent photos? would rather write? can film the work itself?]
Hours per week for social: [HOURS]
Current accounts and traction: [CURRENT: platforms, followers, anything that's ever worked]

Before scoring, name my constraint honestly: from my formats and hours, which platform NATIVE behaviours are open to me and which are closed (short video, photo-led, written posts, community threads) — the platform I can't feed is wrong no matter where my customers are.

Then:
1. THE SCORE MATRIX: for each plausible candidate (choose from Facebook, Instagram, LinkedIn, TikTok, YouTube — only the plausible ones for my inputs): audience fit (from MY customer facts — anything you assert beyond them is marked as an assumption to check by asking ten customers where they scroll), format fit (against my stated formats), local usefulness (groups, maps ties, local discovery), and effort realism against my hours. Scores with one-line justifications — no invented platform statistics.
2. THE CALL: one platform, one runner-up, and two sentences of reasoning anchored to my inputs. If my current traction contradicts the theory (something's already working), weight the evidence and say so.
3. WHAT DEEP MEANS THERE: the platform's three native behaviours I'll adopt (e.g. its short-video grammar, its groups, its search habits), the posting shape and cadence sized to my hours, and the community layer (where replies and conversations happen — the part thin accounts skip).
4. THE 30-DAY DEPTH PLAN: week by week — profile rebuilt for a first-time visitor (draft my bio/description from my details), the first content batch (six post ideas written for MY business in the platform's native shape), the engagement routine in minutes per day, and the one number to watch (platform-appropriate, mine-vs-mine baseline).
5. PARK THE REST: for each other current account — the pinned pointer post, profile note, and check-monthly rule; deletion only if it's actively stale and unloved; say which of mine to park versus quietly retire.
6. THE REVISIT RULE: the two conditions that justify reassessing (the customer evidence changes, or my capacity changes) — and the six-month minimum before second-guessing.

Output: constraint read → score matrix → the call → what deep means → 30-day plan → parking plan → revisit rule.

Rules: use only my stated facts about customers and capacity; mark every audience assumption for validation; no growth promises. Australian English.
