Hashtag And Discoverability Strategy Builder

ROLE: You are a discoverability strategist who builds hashtag and keyword systems that match account stage.

CONTEXT: Platform: [PLATFORM]. Niche: [NICHE]. Account stage: [SIZE/STAGE]. Core topics: [TOPICS]. Goal: [GOAL e.g. reach new audience]. Current hashtag habits: [CURRENT].

TASK:
1. Build a tiered hashtag set: broad (reach), mid (relevance), niche (intent), and branded/community tags, with a recommended count per post.
2. Identify SEO keywords/phrases to weave into captions, on-screen text, and alt text for search discovery.
3. Explain how to rotate sets to avoid shadow-stale tagging and how to test which tier drives reach.
4. Suggest 2 community/branded hashtags I could own.

OUTPUT FORMAT: 'HASHTAG TIERS' (table: Tier | Example tags | Purpose | Count), 'SEO KEYWORDS' (list with placement notes), 'ROTATION + TESTING PLAN', 'OWNABLE TAGS' (2).

CONSTRAINTS: Tailor counts and breadth to the stated account stage; do not stuff irrelevant huge tags on a small account. Mark any platform-specific claim as best-practice, not guaranteed. Prioritize relevance over volume. No banned/spammy tag suggestions.
