AI SEO Case Studies: $20M+ in Attributed Revenue Across Four Verticals

Four published campaigns. Four verticals. Verified revenue, ROI, and AI citation outcomes from real Rankmax engagements.

$20M+ attributed organic revenue | 13,926% highest ROI | 138 AI citations
60/90 days Google visibility to ChatGPT citations | 4 verticals tested

Each case study is measured against the same evidence standard: GA4 revenue and lead attribution, Google Search Console organic growth, ranking movement by URL, and AI citation tracking across platforms such as Google AI Overviews, ChatGPT, Perplexity, Gemini and Copilot. We track AI citations separately because a cited page can create repeated exposure across multiple answer engines, not just one ranking position. Revenue figures are attributed to organic search activity and reviewed against campaign timeframe, vertical, ROI and measurable visibility gains.

Last updated: May 2026. Case study metrics are reviewed against published campaign timeframes, attribution sources and AI citation tracking outputs.
