Methodology: Trakkr queries ChatGPT, Claude, Gemini, and Perplexity with identical prompts and compiles consensus analysis. Scores reflect how frequently and prominently each brand is recommended.

AI platforms generally recommend Google Analytics for marketing teams needing deep Google Ads integration, but favor PostHog for product-led startups and developers seeking a unified tool for experimentation and behavioral tracking.
