Starting Point

There was no tracking in place for ChatGPT, Claude, or Perplexity. Therefore, appropriate UTM parameters first had to be set up in November 2024. The results were based on SEO measures and PR activities, which you can read about in the E-commerce SEO Case Study. Furthermore, at that point in time there were no empirical benchmarks available regarding how ChatGPT or AI in general would develop — there were no comparable case studies or benchmarks.

Therefore, a clear plan had to be developed and a dedicated methodology defined.

Goal

The goal was to position PURELEI as a visible leader in the AI landscape. To achieve this, AI visibility was systematically analyzed and strategically evaluated. The key question was: How does PURELEI currently appear in AI-based answer systems — and what measures will strengthen long-term visibility?

Approach

1. Market Analysis

Identification and evaluation of suitable tools and methods for measuring brand presence in AI systems such as ChatGPT, Perplexity, Gemini, or Claude. Goal: A reliable, repeatedly usable measurement system.

2. Measuring Current AI Visibility

Analysis of how, where, and to what extent PURELEI appears in LLM answer systems. Areas examined included content, recency, consistency, and competitive comparison.

3. Developing Measures

Based on the analysis, concrete strategic recommendations were developed to position PURELEI more strongly in AI answer systems in the short, medium, and long term.

The result is a solid foundation for a sustainable AI visibility strategy.

Results

Prompt Definition

117 prompts were developed. 94 of them are written generically, without any brand mention. Topics covered included brand sentiment, brand awareness, water protection, the Aloha Spirit, longevity, community focus, and quality promise.

Key Factors for Prompt Development

The following were incorporated into the development:

• Product knowledge
• Collections & product lines
• SEO insights
• Customer journeys
• Communication patterns from campaigns and social media
• Blog articles & content clusters

This resulted in a holistic prompt set that represents PURELEI authentically and consistently in AI systems.

A precise prompt definition requires deep brand understanding, customer feedback, pain points, user expectations, and clear unique selling points.

Examples: Generic Prompts

• Best Christmas gifts for women this year
• Gift ideas for women who already have everything
• Are there earrings that look good with sportswear?
• Are there rings that help with anxiety?

Examples: Brand Prompts

• Is PURELEI jewelry made of stainless steel or gold-plated — and does it really last that long?
• Why is investing in PURELEI stainless steel jewelry worth it?
• Why are so many women talking about the PURELEI community?
• Why does PURELEI stand for female empowerment?
• What does the Aloha Way of Life mean at PURELEI?
• What is better — PURELEI or gold-plated fashion jewelry from other brands?
• What advantages does PURELEI offer?

Key statement: PURELEI is not just visible — PURELEI is a top brand in nearly all AI search systems, with a particularly strong presence in Google AI Overviews & Perplexity.

3. Monetary Impact: AI Demonstrably Generates Revenue

The e-commerce tracking analysis shows:

Shop Sessions via AI Channels

• chatgpt.com: 10,463 sessions
• Perplexity: 127 sessions
• Claude & other LLMs: very low volumes (early stage)

Revenue via AI Channels
