Finally got ChatGPT traffic tracked all the way through to signups. AI citations finally paying dividends.

40 years in the agency business, a few SaaS launches in there, building another one now. Not selling anything, sharing a setup because it took me longer than it should have. Everyone says you can't attribute signups to AI assistants. Turns out you mostly can, at least for ChatGPT, because it stamps every link it hands out with utm_source=chatgpt.com and utm_medium=ai-assistant. GA4 then keeps that source on every event in the session, including the signup. Screenshot is my dashboard for the last 30 days: ChatGPT sent at least 14 people, 5 of them finished creating an account

AI 分析

痛点：AI 助手带来的流量难以归因到注册转化：只有 ChatGPT 打 UTM 标签，Gemini 和 Google AI Overviews 完全不打标，GA4 还需跨域链接、事件端触发、排除登录域等复杂配置才能看到真实来源。

目标用户：SaaS 创始人、增长/营销负责人、做 SEO/AEO 的独立开发者

证据：Everyone says you can't attribute signups to AI assistants. Turns out you mostly can, at least for ChatGPT...ChatGPT sent at least 14 people, 5 of them finished creating an account. The month before it sent one. / Any AI visit that arrives without the tag lands in GA4 as Direct and you'll never see it. Gemini and Google's AI Overviews don't tag at all. So it's a floor, not a count. / Not selling anything, sharing a setup

变现：Freemium 订阅制 SaaS：自动识别 AI 来源（含未打标的 Gemini/AI Overviews）并把注册事件归因到 AI 渠道的分析面板，按站点或月活收费；也可作为 AI 可见性/AEO 工具的归因模块单独售卖。

MVP：两周 MVP：一段轻量前端脚本 + 看板，用 referrer、UA 和落地页启发式规则识别 ChatGPT、Gemini、Perplexity、AI Overviews 等来源（不依赖 UTM），打通注册事件做端到端归因，并自动修正常见的跨域/登录域丢源问题。

竞品：Profound、Peec AI、Otterly.ai、Scrunch AI、GA4 原生归因报告

摘要：一位有 40 年 agency 经验的 SaaS 创始人分享了用 GA4 把 ChatGPT 流量追踪到注册的完整配置：30 天内 ChatGPT 带来至少 14 次访问、5 人完成注册，而上月只有 1 次。他指出只有 ChatGPT 会带 utm_source=chatgpt.com 和 utm_medium=ai-assistant，Gemini 与 AI Overviews 完全不打标，未打标的 AI 访问在 GA4 里会归为 Direct，因此现有数字只是下限。这暴露出 AI 流量归因的工具空白与增长团队的付费场景。
