Google ships the button that lets readers mark you as a preferred source without leaving your site

In this logbook2 instalments
Two months ago I wrote here that Liz Reid had confirmed Preferred Sources was reaching AI Overviews and AI Mode, noting that being marked as a source doubled the clicks. There was a clear friction, though: the user had to go manually into Google's settings and look the publication up. That barrier is gone. Google has shipped an embeddable button that lets readers add your site as a preferred source in a single click, without leaving the page they are reading.
How to install the button in two lines of code
The implementation only requires adding a script and a container element. First, load the
script in the <head> tag:
<script async src="https://news.google.com/swg/js/v1/publisher.js"></script>Then, the container where you want the button rendered:
<div google-add-preferred-source-btn></div>
Google renders the element in its official design and translates it automatically to the
browser's language. It takes two optional customization parameters: data-theme,
which accepts light or dark, and data-lang, which
forces a specific language.
Technical requirements: the 2 things that may rule you out
Before deploying to production, two eligibility conditions are worth checking:
- Domain structure: only domains or subdomains qualify (for example, example.com or blog.example.com). It does not work on subdirectories, such as example.com/blog.
- Prior presence in Google: the site must already be registered in Google's source preferences tool; otherwise the button has no entity to associate.
Geographic availability: it works outside the United States
Unlike other features that take months to roll out globally, Google has confirmed general availability. The button is live for Top Stories in every language where Search operates, and also in AI Mode and AI Overviews in the countries where those experiences are already enabled.
User adoption: more than 600,000 sources selected
In June, Google reported more than 345,000 sources manually selected by users in their settings. The current figure is above 600,000 sources, almost double in two months, and measured before this button was released to publishers.
Direct impact: loyalty as a ranking signal
This feature stands out as a technical action you can execute in minutes with direct impact on visibility in AI-generated answers. It does not require changing your content strategy, raising budget or waiting for a core update to resolve.
The key caveat holds, though: the button does not grant visibility by itself, it makes it easier for your audience to decide to grant it. Its effectiveness depends on offering real value to justify the user's click. Community loyalty consolidates, for the first time, as a direct ranking factor.

Google Search's VP says what works in the AI era, defensible content and not generic
I sat through all 75 minutes of Liz Reid's interview, VP of Google Search and 23 years at the company, on the AI Inside podcast, and some lines belong framed on every agency wall. The bluntest was about paywalls: "sometimes they put up a paywall and then say their traffic has dropped; and I tell them: yes, that is exactly what happens when you charge". No anesthetic.
What interested me most was what she said about small publishers. Personalization in AI Mode pushes results toward the long tail: when Google knows you care about eco-friendly brands or that you just had a baby, it can surface the specialist reviewer, the local shop or the niche creator. Without personalization, the same names always win. For a small, focused business, that is a door that used to be closed.
She also confirmed that Google has extended Preferred Sources to AI Overviews and AI Mode. Your readers can mark you as a preferred source and, when they do, your links show up with a visible badge in AI answers. The figure that raised my eyebrow: twice the clicks, and there are already more than 345,000 sources selected. Your audience's loyalty, for the first time, translates directly into visibility inside AI.
The underlying message is underlined in my notes: content an AI summary can compress into three sentences is vulnerable; content with proprietary data, expert opinion and a unique perspective is defensible. So the takeaway I keep for any project is not to produce more generic content faster. It is the opposite: fewer pages, but ones that deserve to have someone mark you as their preferred source.
