Google confirmed that search query reports for ads triggered through AI Mode, AI Overviews and Google Lens may display a closest approximation of the user's query rather than the actual search term. The company framed this as a necessary translation for queries that do not have a traditional text-based equivalent.
The practical impact is significant. If you are running Google Ads and relying on search query reports to build negative keyword lists, identify new keyword opportunities or understand user intent, the data feeding those decisions may not be precise. A user asking an AI Mode conversational question about plumbers in Melbourne might show up in your report as a simplified keyword match that strips the context and nuance from the original query.
Google's explanation is that some AI-driven search formats produce queries that are too long, too conversational or too visual to fit neatly into a traditional search term report. The approximation is designed to give advertisers something usable rather than nothing at all.
Why it matters
Search query reports are one of the primary feedback loops in paid search management. Negative keyword lists, match type decisions, ad copy testing and budget allocation all flow from understanding what people actually searched before clicking your ad. If that data is an approximation, every downstream decision carries a margin of error that did not exist before.
Google surfaces now using query approximation in search term reports: AI Mode, AI Overviews and Google Lens
For Australian businesses spending on Google Ads, this means the gap between what you think is working and what is actually working just got wider. Particularly for businesses in categories where AI Mode adoption is high, like local services, health and professional services.
What to do about it
Do not stop using search query reports. They are still the best signal available. But cross-reference them against landing page analytics and conversion data more aggressively than before. If your search term report says a query converted but your landing page data does not support the intent match, flag it. Build a habit of validating paid search data against first-party analytics, because the days of taking Google's reports at face value are over.
