In short. Gemini's double-check links identify content found by Search to evaluate statements, without establishing which sources informed the initial response.
Definition: Gemini's double-check links point to content found by Google Search to evaluate statements in an existing response. Google explicitly says those links do not imply that the linked sources informed the initial response.
Key facts
- Google's release notes, in the entry dated 19 September 2023, distinguish links found by Search from sources that informed the initial answer.
- Google's double-check announcement describes reading an existing response and finding supporting or contradicting information through Search.
- As of 17 October 2026, Google's sources help page describes a Sources button and related links, including public websites and uploaded files.
What does double-check actually evaluate?
Google's announcement describes the feature under the product name Bard. Selecting the “G” icon makes the assistant read its response and evaluate whether web content substantiates it. Highlighted phrases provide access to supporting or contradicting information found by Search.
The sequence matters: a response already exists when the check evaluates its statements. A linked page can therefore help a reader assess the statement's support. A page's support for a statement and its use in composing the answer are separate questions.
What does Google say about original source use?
The relevant release note is titled “Double-check Bard’s responses with Google It v2”. Google explains that the links are content found by Search; their presence carries no implication that those sources informed the initial response.
For a website owner reviewing a double-check result, the documented observation is that Search found the page during this evaluation. Treating that result as proof of original source use exceeds Google's description. A report can identify the page as a double-check link and retain the associated statement so that the relationship remains clear.
How does this differ from the Sources panel?
Google's current help page describes sources and related content within or below a response. The Sources button opens relevant links in a side panel. These may include public websites, uploaded files, or connected Google Workspace documents and emails.
The same help page says a webpage appears in the sources list when Gemini directly quotes a large amount of its text. It also documents source links for web images. These are specific explanations for links displayed with responses. The English page currently omits double-check instructions, while the release notes retain the explicit explanation of double-check links.

FAQ
Can I report a double-check link as proof Gemini used my page?
Google's release notes explicitly rule out that inference from the link alone. You can describe the observed result as a link found by Search during double-checking.
Where can I inspect links provided with a response?
Google's sources help directs you to the Sources button below the response or inline. Selecting it opens a side panel containing the relevant links.
