I'm in a broad niche but analyze: should I go micro-niche? Map the micro-niche strategy: dominating tiny niche then expanding vs. being small fish in big pond. Calculate: would being #1 in micro-niche give more growth opportunity than being #1000 in broad niche? Give me the micro-niche identification: these are underserved micro-niches within my broad niche. Include: when micro-niche is smart vs. when it's limiting, how to dominate micro-niche then expand, and why broad niche might be preventing dominance.
