AI Perception

Analysis

Insights & Recommended Actions

What's working, what's not, and specific steps to improve Death Clock's AI visibility.

Key Findings

Strength

Absolute dominance in lifespan prediction and mortality tracking queries with #1 rankings in Gemini, Claude, and AI Overviews.

Strength

Strong resonance with the 'Mid-Life Intentionality Seeker' persona, achieving a near-perfect average position of 1.5.

Strength

Exceptional performance in AI Overviews with a 31% mention rate and #1 average position across relevant queries.

Recommended Actions

1

Develop and seed content focused on 'Longevity Planning' and 'Biohacking Routines'.

The brand is currently ignored for holistic planning queries; appearing in these results is necessary to compete with InsideTracker and Oura.

2

Initiate a ChatGPT sentiment recovery campaign through authoritative PR and technical documentation.

Negative sentiment and a position of 9.0 on the most used AI platform actively discourages adoption and damages brand trust.

3

Optimize for 'Quantitative Longevity Researcher' queries by publishing methodology whitepapers.

This persona drives the technical authority that LLMs use to validate health tech recommendations; winning here improves visibility across all segments.
