A rule intended to limit AI use can also affect whether Google uses a website for grounding Gemini answers. That makes it worth checking before concluding your community needs a new website provider or more general marketing content.
LeasingAI’s production research found a substantial citation gap between apartment websites that blocked Google-Extended and those that did not.
The finding
Among communities named in Gemini answers, their own websites were cited 4.9% of the time when they blocked Google-Extended, compared with 13.9% when they did not. The difference is approximately 65% lower.
The comparison excluding websites also blocking Googlebot retained that Gemini gap. ChatGPT’s citation rates in that comparison were similar: 23.7% and 24.1%.
This is an observed association across websites, not a randomized test proving that changing one rule recovers a particular number of citations. The result is still specific enough to justify checking the setting.
What Google-Extended controls
Google describes Google-Extended as a product token controlling use of crawled content for future Gemini training and grounding in specified Gemini products. It does not control inclusion or ranking in Google Search. Google’s current documentation.
A website can therefore remain available in Google Search while expressing a restriction relevant to Gemini.
Check the actual rule
Open the community domain followed by /robots.txt and look for a group like this:
User-agent: Google-Extended
Disallow: /Review the whole applicable group and file rather than relying on a text match alone. A managed section may be inserted by the hosting or security configuration.
Cloudflare’s current Bot Preference Sync documentation shows managed directives containing this block under relevant policy settings. The source of the rule matters because manually editing a generated section may not provide a lasting change. Cloudflare documentation.
Decide deliberately, then verify
Ask the responsible website or security team where the restriction originates and what policy the owner wants. Allowing the relevant use also permits the training use described by Google. Do not present that as an unexplained SEO switch.
If the owner approves a change, update the responsible configuration, retrieve the served robots.txt again and verify the applicable rule. Then monitor subsequent Gemini answers and own-site citations. There is no guaranteed recovery time or citation outcome.
Removing this restriction does not override other technical, security or content issues. A page can still be unavailable, confusing or poorly matched to the renter’s question.
Why this is the kind of issue LeasingAI investigates
LeasingAI connects AI answers and sources to property-specific readiness work. The useful output is an identifiable issue, an explanation, a responsible next action and a way to check the result.
Your marketing team should not have to guess whether a visibility problem is a writing task, a rental-data conflict or an access setting.
Methods
The research window was October and November 2026, covering ChatGPT and Gemini. Robots.txt was read in November 2026, so the snapshot does not establish that every rule was unchanged throughout the answer window. The outcome is an own-site citation conditional on the community being named.
The broader production study contained 218,619 answers and approximately 1.12 million community mentions. The robots analysis found 173 blocking sites among 7,712 checked community sites. The clean comparison excludes sites also blocking Googlebot; headline rates above use that reanalysis. No client identities are disclosed.
