Youth & Earth is a UK-based longevity supplement brand competing in a crowded AI-answer category. SUBJCT tracked and optimised its visibility across ChatGPT, Google AI Overviews and Perplexity from a near-zero starting point, structuring its content for AI search and tracking the result.

- Rank among 33 tracked competitor brands rose from ~#9 to #2 by average position over the same window.
- Overall visibility rose 41.6%, from 5% to 7.08% of AI answers in category, verified against Peec AI at the end of April 2026.
- Outcome: 16 comparison articles, entity/linking/schema work, and monthly Peec AI tracking gave Youth & Earth structured AI-search visibility for the first time.

THE CHALLENGE
Low AI-search visibility outside branded and NMN queries
When tracking began in February 2026, Youth & Earth sat at roughly #9 by average position among 33 tracked competitors, with an average position of 3.2 and overall visibility of 5% of AI answers in its category.
Two structural gaps were limiting performance:
- Zero configured topics in Peec — limiting the brand’s ability to track performance by content theme.
- Prompt concentration — heavy weighting toward NMN and UK-purchase intent, alongside a branded-to-unbranded prompt ratio. This activity focused on improving core longevity and NMN prompts specifically.

THE APPROACH
SUBJCT’s AI-powered content optimisation
Between February and April 2026, SUBJCT delivered three workstreams, each replacing a manual or absent process with structured, tracked output.
Workstream A — Comparison content
SUBJCT produced product- and competitor-comparison articles, including a GEO sub-edit of existing longevity-related content.
Workstream B — Entity, linking & schema
SUBJCT applied entity analysis, semantic internal linking and Schema JSON-LD across the content set via the SUBJCT platform.
Workstream C — Tracking & measurement
SUBJCT configured and ran monthly Peec AI tracking across three engines.

METHODOLOGY

Overall visibility rose 41.6% (5% → 7.08%), verified from Peec AI, run at the end of April 2026.

WHAT THIS MEANS FOR YOU
A repeatable path from near-zero to #2
For a brand starting from a near-zero AI-search footprint, moving from #9 to #2 by position within two months — a 37.5% improvement in average position, alongside a 41.6% increase in overall visibility (5% to 7.08%) — shows AI visibility responds to entity clarity, topical coverage and well structured content.
