Key finding:
MEL Science holds a real but contested organic position (DR 59, 21.7K organic visits/mo, 6.4K keywords) — a clear #2 by keyword breadth among the 5 tracked brands, but well behind the category leaders on traffic:
Spangler Science Club and Groovy Lab in a Box are nearly invisible organically (19 and 0 visits/mo) despite legacy domain authority — MEL Science already beats both smaller players comfortably
In AI answers, the pattern repeats: KiwiCo and CrunchLabs are cited directly in buying-decision prompts (“is X worth it”, “X vs Y”), while MEL Science's citations come mostly from unrelated long-tail blog content — a GEO gap the content plan below should close (see GEO section).

Key findings:
KiwiCo leads every column — the category benchmark to close the gap against
CrunchLabs' traffic-to-keyword ratio (44.7K visits from only 356 keywords) signals brand-search dominance, not topical breadth — an opening for MEL Science's much broader keyword footprint (6.4K keywords) to compound over time
Spangler Science Club and Groovy Lab in a Box carry legacy domain authority (DR 69 / 36, large historic backlink counts) but essentially no live organic traffic — their SEO programmes are dormant

GEO / AI visibility. MEL Science is present in AI answers (69.9K combined impressions/mo, 17.6% share of voice, 5 ChatGPT domain citations) but the composition of that visibility is the real story: KiwiCo (9 citations) and CrunchLabs (14 citations) are cited directly in buying-decision prompts — "Is KiwiCo the same as CrunchLabs?", "How does CrunchLabs compare to KiwiCo?", "Are CrunchLabs boxes worth it?" — the exact moment a parent is choosing which box to buy. MEL Science's 5 citations, by contrast, come almost entirely from unrelated long-tail blog content (what to do with pine cones, what liquid glass is used for, DIY Halloween fake skin) — useful traffic, but it doesn't touch purchase intent. Spangler Science Club and Groovy Lab in a Box have zero AI impressions and zero citations — a blank GEO slate. Priority: build citable, comparison-style content ("MEL Science vs KiwiCo", "Is MEL Science worth it?", "MEL Science pricing") to convert existing AI presence into purchase-intent visibility.

Cumulative ROI
Model = ESA ROI Calculator (cohort ramp → brand/LLM channels → funnel → cumulative ROI)
Behavioural assumptions held at the Healthy tier (months-to-peak 7, success 60%, brand-amplification ×3.5, LLM ratio 0.10, LLM conv ×2.0, visit→signup 9%, signup→paid 3.7%, avg visits/page 150, LTV $180)
LTV $180 is an industry assumption (≈6-month average subscription retention at melscience.com's ~$30/mo entry tier) — the dominant lever; replace with MEL Science's real LTV to firm up ROI
