Mac MacDonald

I am the founder of AI Sightline, an AI search visibility monitoring platform. I built AI Sightline to answer a question most brands still cannot: "How does ChatGPT describe us?" The platform monitors how brands appear across six generative AI platforms (ChatGPT, Google Gemini, Perplexity, Microsoft Copilot, Google AI Mode, and AI Overviews) and tracks citations, sentiment, and competitor positioning across each. Before founding AI Sightline, I spent 20 years in enterprise SaaS, leading consumer engagement and SMB marketing programs at brands including Cox Communications and GoDaddy. I am based in Arkansas and write and speak on Generative Engine Optimization (GEO), how large language models select sources, and how brands earn visibility in AI-generated answers.
