# ChatGPT 搜索大规模启用 site: 运算符，GEO 监测揭示产品变化

## AI 点评

> OpenAI 很少公开搜索排序细节，能通过外部追踪看到 site: 运算符的跃升，说明产品行为正在被量化观测。做搜索流量或内容策略的人，应该把这类监测当作默认工具，而不只依赖官方公告。

## 速览

ChatGPT 搜索已开始大规模使用 site: 站点限定符。Promptwatch 监测显示，该运算符在 ChatGPT 搜索查询中的占比从长期徘徊的 0.3%-0.5%，在 8 月 8 日跃升至 16%-17%，与 GPT-5.6 更新及 OpenAI 关于“更可靠事实、更聚焦答案”的公告吻合。这一变化意味着生成式引擎优化（GEO）进入新阶段，同时 ChatGPT 对 Reddit 等站点的依赖也显著降低。对站长、SEO/GEO 从业者与 AI 搜索研究者而言，这是观察搜索流量分配规则变化的信号。

## 关键点

- Promptwatch 数据显示，ChatGPT 搜索中带 site: 的查询从 0.3%-0.5% 跃升至约 16%-17%
- 变化时间与 GPT-5.6 更新及 OpenAI 8 月 6 日公告一致
- 后续监测显示 ChatGPT 搜索对 Reddit 的依赖明显下降
- 因 OpenAI 不公开系统提示词，外部只能通过行为追踪推断机制

## 全文

ChatGPT search now uses the site:operator at scale Promptwatch is part of the emerging "GEO" space, for Generative Engine Optimization - the chatbot version of SEO, where companies offer tools and consulting to help your site increase its presence in replies to prompts inside tools like ChatGPT. The Promptwatch product uses automation to track responses to prompts across end-user chat products like ChatGPT, Claude, and Gemini. They publish aggregate reports on this as part of their own content marketing strategy, which do seem to provide credible hints as to otherwise invisible design changes to those products. Their own tracking shows a notable change aligned with the GPT-5.6 rollout earlier this month: The percentage of all ChatGPT Search fanout queries that contain the site:operator, per day. The share hovered between 0.3% and 0.5% for weeks, dipped briefly to 0.15% on August 3 to 5 (consistent with a staged rollout or pre-launch experiment), then jumped to 16-17% on August 8. It's important to note that these figures only reflect the prompts for which they have automated tracking enabled. This corresponds to OpenAI's somewhat vague August 6th announcement: For Plus and Pro users, we’re updating GPT‑5.6 Sol in Chat to be more reliable with facts and provide more focused answers. Once again I am hampered by OpenAI's decision to actively obscure their system prompts, but from poking at ChatGPT I believe their latest search tool has a shape like search(query, recency, domains) rather than encouraging a site: operator directly. In a follow-up on August 18th Promptwatch reported that ChatGPT appeared to have greatly reduced the likelihood of Reddit being used in those searches. My own attempts to ascertain if the system prompt has been updated to discourage Reddit sourcing have been unsuccessful - the most thorough leaked system prompt collection I know of doesn't yet show any relevant changes.
