Google Preferred Sources: How to Become a Preferred Source in AI Search

Most of the SEO levers I work with have one thing in common: in the end, an algorithm decides. You optimise content, tech and signals – and hope Google’s ranking system rewards it. “Preferred sources” work differently. Here it is not the algorithm that decides first, but your reader. With a click.

And this lever just became considerably more valuable. On 27 May 2026, Google announced that preferred sources no longer appear only in Top Stories, but – as of now – also in AI Overviews and AI Mode, each visibly marked with a label. The announcement on the official Google blog comes from Duncan Osborn, Product Manager for Google Search.

The most common question in my SEO Kreativ client calls over the past few months runs roughly like this: “We rank on page one – so why isn’t any traffic coming through?” The answer is almost always the same: the AI summary that, in many cases, sits above the classic results. That is exactly why a channel in which your most loyal readers actively push you up is rare good news right now. But – and this matters to me – it is no silver bullet. Let’s look at what is really behind it.

The principle is simple: in Google’s source settings (or via the star icon next to Top Stories) a user defines which websites they want treated as a “preferred source”. Google then prioritises these sources for that specific user – in personalised news and search results.

The short timeline, so you place it correctly:

• 12 August 2025: Launch in the US and India (after the Search Labs experiment from 26 June 2025), initially for Top Stories.
• December 2025: Expansion to English worldwide.
• 30 April 2026: Roll-out globally for all supported languages.
• 27 May 2026: The key change here – preferred sources are now also shown in AI Overviews and AI Mode. According to Google the display starts immediately, with the full roll-out continuing over the following weeks.

Until now the effect of preferred sources was limited to Top Stories – the headlines box. With the expansion the mechanism now reaches the two surfaces that are currently redistributing traffic: AI Overviews (the AI summaries above the classic results) and AI Mode (the standalone AI chat).

In concrete terms, per Google’s description: if one of your pages is linked as a source in an AI-generated answer and the user has previously set you as a preferred source, that link is clearly marked – just as users already know it from Top Stories. The reader sees at a glance: “This is a source I chose myself.”

In parallel, Google introduced two further visibility elements in AI Search: an extended label for frequently cited sources, plus new carousels – one for topics with growing attention, one with sources from social media and forums for opinion-based queries. For the strategic context of how AI Overviews and AI Mode interact, see my piece on the difference between AI Mode and AI Overviews.

Two things set this lever apart from classic SEO: the mechanics and the numbers.

The mechanics first. No amount of clean on-page optimisation wins you a preferred source – only your reader does, via opt-in. That is unusual, because we SEOs are trained to turn dials the algorithm evaluates. Here the “dial” is the relationship with your audience. For me, that makes the channel comparatively robust: it is hard to manipulate and does not hinge primarily on core-update swings.

For a fair assessment, though: right now the effect works mainly via the visible label and the higher click-through. Google highlights preferred sources in AI Search and shows them to users who have selected the source – so they can appear more often and more prominently within these surfaces. So it is not a classic ranking signal, but a user-driven visibility mechanism.

Then the numbers Google cites:

In an environment where AI Overviews noticeably depress click rates, a doubled click-through likelihood is not a cosmetic value. For brands suffering under the zero-click effect, this is exactly the kind of lever I am currently building into my consulting: don’t fight the algorithm, activate your own reader base.

Here is the workflow I set up for seo-kreativ.de and for clients. Three steps, clear order.

Step 1 – check eligibility. Before you call for anything: check whether your domain is even findable in Google’s selection tool. Google names fresh content as the criterion; whether your domain shows up is revealed by the tool itself. If your site has been dormant for months, that is your first to-do – not the opt-in button.

Step 2 – move readers to opt in. This is the actual lever. Your reader has to act. Explain concretely how:

• Via the star icon next to Top Stories in Google Search.
• Or directly via the Google source settings (Google account login required), where you search for and add the website.

Put this prompt where your most loyal readers are: at the end of strong articles, in the newsletter, in the author box. Someone who has just read you with benefit is in the right moment for the ask.

Step 3 – make it visible on your own site. Only once eligibility is in place does a visible integration pay off: a short, honest call-to-action (“Make seo-kreativ.de your preferred source on Google”) with a mini guide. No pop-up bombardment – one clear, well-placed prompt.

You don’t have to build the button yourself. Google provides the finished badge graphics as an official download – in 16 languages, including English. You’ll find them right in the Search Central documentation on preferred sources, where Google links a ZIP with all language variants. You then point the button at https://www.google.com/preferences/source?q=your-domain.com – that opens the source settings with your domain pre-filled. This is the exact official asset sitting behind the button below.

And so you don’t have to assemble the box by hand – here is the full copy-paste template: text on the left, the official Google button on the right. You only swap two things: q=your-domain.com in the link and the image path to your downloaded badge graphic.

<div class="ps-cta">
  <div class="ps-cta-text">
    <strong>Make me your preferred source</strong>
    <span>Mark me in Google Search - my posts will then show up higher for you.</span>
  </div>
  <a class="ps-cta-badge" href="https://www.google.com/preferences/source?q=your-domain.com"
     target="_blank" rel="noopener" aria-label="Add as a preferred source on Google">
    <img src="/path/to/your-google-badge.png" alt="Add as a preferred source on Google">
  </a>
</div>

How to build content so AI systems pick you up as a source in general, I describe in my foundational article on the way AI Overviews work – preferred sources are the bonus, clean citability remains the duty.

Try it directly: If my posts help you, add seo-kreativ.de as a preferred source with a single click – the official Google button opens the source settings with seo-kreativ.de already pre-filled (Google account login required).

I wouldn’t be honest if I ended this post on pure optimism. Whoever only hopes for the opt-in button confuses reader loyalty with search-engine cosmetics. Three sober points:

• It is user-dependent. The effect only arises with users who actively chose you. You don’t gain reach with first-time visitors this way.
• It does not solve the click problem. If the AI answer already delivers the core info, the user still needs a reason to click. The label makes you more visible, but the content has to deliver the value behind the click.
• The surface belongs to Google. Your content is still summarised and embedded in a search environment that belongs to Google first. Preferred sources shift the balance of power only gradually.

My take: take the lever – it costs you little and can have a noticeable effect with a loyal readership. But treat it for what it is: one building block in a broader strategy, not its foundation. The foundation remains unique, non-interchangeable content – exactly what Google also stresses in its updated recommendations.

For me the real message of this change is bigger than the feature itself: in the middle of the AI upheaval, Google is opening a channel where it is not the algorithm but the relationship with your audience that decides your visibility. That fits what I’ve been observing for a while – brand, loyalty and trust are becoming the hardest currency in the AI era. Why SEO as a whole is shifting from a click economy to a citation economy, I’ve described separately in more detail.

My advice: build this into your routine. Check your eligibility, add an honest opt-in prompt, and make it easy for your most loyal readers to pull you up. It costs little and pays off measurably with an engaged readership.

Update (June 2026): I’ve added the finished CTA box as copy-paste code to the playbook above – so you can drop the opt-in prompt straight into your own site instead of rebuilding it.
