Internal benchmark testing

What our internal benchmark testing showed.

Genesis tested against a human copywriter and a raw off-the-shelf LLM on the three numbers that actually move revenue. These are internal benchmark results, not customer outcomes — we don’t have published merchants yet, and we won’t pretend otherwise. Full methodology below.

  • n=142 product listings, 7 verticals
  • 30 days of testing, Feb–Mar 2026
  • 14 A/B tests measured live conversion lift
⚙️ How these numbers were measured (methodology)

Sample size: 142 product listings across 7 e-commerce verticals (apparel, candles, kitchenware, jewelry, pet supplies, home decor, beauty), generated and scored over 30 days in February-March 2026.

Comparison conditions: Same product specs given to all three: (1) Genesis 5-model council, (2) a commodity single-prompt LLM with a competent prompt template, (3) human copywriter with 4+ years e-commerce experience. Time measured from input to publishable output.

SEO score: Composite of Lighthouse SEO + on-page SEO scoring rubric (title tag length, meta description quality, keyword distribution, heading hierarchy, internal linking signals).

Conversion lift: Measured in 14 published cases via A/B test against the original listing on the same product, 30-day window, equal traffic split. The +18% is a median; range was +8% to +27%.

What the council actually writes

Before/after samples. Real council output.

Three sample rewrites in common Shopify niches. Same product specs in, real council output out. Niches are real; brand names are intentionally not.

Anonymized stylistic samples generated by the production council on common product types. Not customer listings — we don’t have published merchants yet.
