Case study cover

Problem

Strong product, weak presence in AI search. Prospects were asking ChatGPT and Perplexity for recommendations, but inconsistent visibility meant losing high-intent users before site visits.

Approach

Treat AI referrals as measurable acquisition channels and run a weekly GEO loop: monitor keyword visibility, publish useful answers, track share of voice, and iterate from live AI outputs.

Outcomes

  • AI referral share: 15.64% → 29.91%

  • ChatGPT referrals: +102%

  • Perplexity referrals: +57%

  • AI user conversion lift: 2.3x

Why trust this?

In five months, Writingmate.ai grew AI referral share from 15.64% to 29.91% by focusing on AI visibility across ChatGPT and Perplexity.

The method was consistent: keyword monitoring, helpful replies, and weekly share-of-voice tracking.

The insight

AI referrals follow visibility, and visibility can be measured. GEO requires tracking presence inside AI systems, not only rankings in traditional blue-link search.

  • Treat ChatGPT and Perplexity referrals as measurable channels.
  • Track share of voice on priority intents every week.
  • Reinforce citable signals with structured, useful answers.

The process

Writingmate.ai ran a four-step GEO playbook:

  1. Keyword monitoring for AI search across buying-intent topics and question clusters.
  2. Helpful replies that earn mentions by prioritizing clarity and usefulness over volume.
  3. Weekly share-of-voice tracking to accelerate iteration and catch visibility loss early.
  4. Iteration from real AI outputs based on intent coverage and competitor narratives.

The proof and results

This was not a one-off campaign. The team continuously monitored, published, measured, and refined, and referral growth followed visibility gains.
