Gemini Says 'The Gold Standard.' Copilot Has Barely Heard of It.

Executive Summary

• Brand: Mejuri is a Canadian DTC fine jewellery brand. The category default for AI agents on most platforms.
• AI visibility score: 94/150 (63%) — the highest in the jewellery audit set
• The pattern: Extreme platform divergence. Gemini: 86%. ChatGPT: 78%. Copilot: 24%. The same brand experiences three completely different realities.
• Key competitor gap: On Copilot, Missoma, Monica Vinader, and Astrid & Miyu — UK-market brands — take every slot.
• Root cause: Strong North American editorial presence drives ChatGPT and Gemini. Weak presence in UK editorial sources leaves Copilot as a blind spot.
• Fix complexity: Low for the Copilot gap — requires UK editorial roundup inclusion.

The brand

Mejuri is the jewellery category default for AI agents. It appears across virtually every query on ChatGPT and Gemini. Layering necklaces, affordable gold, herringbone chains, gift suggestions, everyday wear — Mejuri is typically the first or second recommendation.

The test

I ran 150 automated queries across ChatGPT, Gemini, and Copilot — 10 runs per query per platform, across five queries designed to test everyday fine jewellery recommendations.

The results

• Gemini: 86% visibility. Mejuri surfaces in nearly every test. Described as "The gold standard" for everyday fine jewelry and "Best Overall." Position 1.0 on huggie hoops. Position 1.2 on layering queries. Dominant.
• ChatGPT: 78% visibility. Mejuri is the first recommendation for DTC jewellery in every single test. Strong on product-specific queries.
• Copilot: 24% visibility. Mejuri barely exists. Instead, Copilot recommends Missoma, Monica Vinader, and Astrid & Miyu — UK-market brands that most North American shoppers have never heard of.

Same brand. Same products. Same day. Three completely different realities.

Why this is happening

There is no single "AI visibility score." Each platform has its own editorial biases, its own data sources, and its own recommendation logic.

Copilot draws heavily from UK editorial roundups, which is why British jewellery brands dominate its recommendations. Gemini appears to weight brand reputation and media coverage. ChatGPT synthesises from a broader set of editorial "best of" lists.

The practical implication is uncomfortable. You cannot optimise for "AI" as a single channel. You need to understand where each platform sources its recommendations and build presence in those specific places.

What Mejuri could do, in priority order

Phase 1 (quick wins):

• Pursue UK editorial roundup inclusion to close the Copilot gap
• Ensure product data is consistent across all market-specific pages

Phase 2 (medium effort):

• Build editorial presence in UK media specifically targeting Copilot's source material
• Create market-specific landing pages that resonate with UK editorial standards

Phase 3 (longer term):

• Monitor platform-specific visibility as each AI agent evolves its recommendation logic

Close

Mejuri demonstrates the most important lesson in AI commerce visibility: there is no single "AI" to optimise for. Each platform draws from different data sources, different editorial references, different recommendation logic.

For Mejuri, the gap is clear. Strong editorial presence in North American media drives ChatGPT and Gemini visibility. Weak presence in UK editorial sources leaves Copilot as a blind spot.

For most brands, the gaps are less obvious. They do not know where they are invisible because they have never tested it. The first step is always the same: ask the AI what you sell. Do it 10 times, not once. Do it on all three platforms. The pattern will tell you everything.
