ChatGPT 搜索现已大规模使用 site: 运算符
英文标题:ChatGPT search now uses the site:operator at scale
Promptwatch 的追踪数据显示,ChatGPT Search 在查询扇出(fanout)中使用 `site:` 运算符的比例,于 8 月 8 日从此前长期的 0.3% 至 0.5% 跃升至 16% 至 17%。这一变化与 OpenAI 在 8 月初推出 GPT-5.6 Sol 更新的时间大致吻合,但数据仅覆盖 Promptwatch 已启用自动化追踪的提示词。Promptwatch 还发现,ChatGPT 在搜索中引用 Reddit 的概率似乎显著下降。该变化意味着 OpenAI 可能正在通过内部的域名筛选参数优化搜索,而非直接引导模型生成 `site:` 查询语法。

ChatGPT 搜索现已大规模使用 site: 运算符。Promptwatch 属于新兴的“GEO”领域,即生成式引擎优化(Generative Engine Optimization)——可视为面向聊天机器人的 SEO。该领域的公司提供工具和咨询服务,帮助网站提升其在 ChatGPT 等工具针对提示词生成的回答中的曝光度。
Promptwatch 产品通过自动化方式,追踪 ChatGPT、Claude 和 Gemini 等面向终端用户的聊天产品对提示词作出的回复。作为其自身内容营销策略的一部分,该公司会发布相关的汇总报告;这些报告似乎能够为这些产品原本不可见的设计变更提供可信线索。
该公司的追踪结果显示,在本月早些时候 GPT-5.6 推出期间,出现了一项显著变化:
每日所有包含
site:运算符的 ChatGPT Search 扇出查询所占比例。该比例数周来一直在 0.3% 至 0.5% 之间徘徊,随后于 8 月 3 日至 5 日短暂降至 0.15%(这与分阶段发布或上线前实验相符),再于 8 月 8 日跃升至 16% 至 17%。
需要注意的是,这些数字仅反映了 Promptwatch 已启用自动化追踪的提示词。
这与 OpenAI 略显模糊的 8 月 6 日公告相对应:
对于 Plus 和 Pro 用户,我们正在更新 Chat 中的 GPT‑5.6 Sol,使其在事实准确性方面更加可靠,并提供更聚焦的回答。
OpenAI 决定主动遮蔽其系统提示词,这再次妨碍了我的研究;但通过对 ChatGPT 的试探,我认为其最新搜索工具的形态可能类似于 search(query, recency, domains),而不是直接鼓励使用 site: 运算符。
在 8 月 18 日发布的后续报告中,Promptwatch 称,ChatGPT 在这些搜索中使用 Reddit 的可能性似乎已大幅降低。我自己尝试确认系统提示词是否已更新、以避免将 Reddit 作为信息来源,但未能成功——我所知最完整的泄露系统提示词合集,目前尚未显示任何相关变更。

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.
