Relixir vs AthenaHQ: 30-Day Head-to-Head eCommerce GEO Test (Q3 2025 Results)

Introduction

AI search is reshaping commerce discovery. More than half of decision-makers now prefer AI for complex inquiries, fundamentally changing how customers find and evaluate products. (MIT Technology Review)
Traditional SEO is losing ground fast. Organic click-through rates have dropped by more than half—from 1.41% to 0.64%—for informational queries when AI answers appeared. (Relixir)
GEO platforms promise the solution. Generative Engine Optimization tools like Relixir and AthenaHQ claim to flip AI rankings in 30 days, but which delivers real ROI?
This live experiment settles the debate. We ran two matched Shopify stores through identical 30-day tests, measuring visibility lifts, answer-share percentages, and pipeline impact across ChatGPT, Gemini, and Perplexity.

The AI Search Revolution Demands New Tactics

The search landscape has fundamentally shifted in 2025. Google's Search Generative Experience uses AI Overviews to present synthesized facts with source links at the top, while Microsoft Bing integrated GPT-4 into search to create Bing Chat. (AI Search Wars) Meanwhile, Perplexity AI secured a $500 million funding round in May 2025, led by Accel, raising its valuation to $14 billion and reaching over 15 million monthly users by April 2025. (Perplexity AI Report)

For eCommerce brands, this shift is critical. The average order value for e-commerce stores in the USA was $137.57 with a conversion rate of 2.10% in 2024. (Grips Intelligence) When AI engines influence up to 70% of all queries by the end of 2025, brands that don't optimize for generative search risk becoming invisible to their target customers.
