Rank-Tracking Tools Are Returning Scrambled Google Data

Who it affects: Any site using third-party rank trackers

Rank-tracking company Nozzle found that from Sept. 13 to Oct. 9, 8.0% of the Google results pages it could check against history were missing most of the usual sites for that keyword, compared with just 0.17% in the prior month. The share peaked near a quarter of pages between Sept. 27-29 and has run at roughly 5% to 11% a day since Oct. 1. On these affected pages, a client's own site failed to appear in the top 10 58.6% of the time, versus 2.7% normally. Nozzle links the pattern to Google's response to AI scraping, though Google hasn't commented on it.

What this means for your website

If a rank report shows a sudden drop this month, check Search Console for a matching dip in impressions and clicks for that same query and page before you treat the drop as real or report it to a client.

Study: Free Workarounds Miss Half Of ChatGPT's Real Sources

Who it affects: Anyone using Google rankings or OpenAI's API to guess ChatGPT citations

A preprint from researchers at the National University of Singapore and Xi'an Jiaotong University tested whether Google search results and OpenAI's Responses API could stand in for watching ChatGPT's actual citations directly. Combined, the two substitutes found only 26.2% to 28.3% of the exact pages ChatGPT cited across four model versions, though they caught 48.7% to 50.3% of the actual cited sites. ChatGPT never searched using a question's exact wording in the tested models, often ran searches in English even for Chinese-language prompts, and which pages got cited varied heavily between repeated runs of the same question. The researchers recommend monitoring at both the page and site level, running prompts multiple times, and checking whether any tracking tool pulls data through OpenAI's API versus the live ChatGPT app.

What this means for your website

If you're using a rank tracker or a Google-ranking proxy to estimate your ChatGPT visibility, treat the result as a rough site-level signal rather than proof of which exact page gets cited, and ask any AI-visibility tool you pay for whether it sources data from the ChatGPT app or from the API.
