Google Preferred Sources

Preferred Sources is a Google Search setting that lets a reader nominate the sites they want to see more of. It is one of the few personalisation signals a publisher can openly ask an audience to set, which is why it draws more attention from SEOs than a display setting normally would. How much it changes on each surface is less settled than it looks. Google’s documentation and its own product copy describe the effect differently, and the gap between them decides how much weight the feature deserves in a plan.

What is Preferred Sources?

Preferred Sources lets a signed-in user mark specific publications as sources they want prioritised. Google describes the effect in two distinct ways, and the distinction matters.

Google’s documentation splits the effect by surface, and keeps the split in both the publisher and the reader-facing versions. For Top Stories, the developer documentation says content from a preferred source is “more likely to appear”,¹ and the help centre tells readers they will “find these sources more often in Top stories”.² For AI Mode and AI Overviews, the developer documentation says content “can be highlighted with a ‘preferred’ badge”,¹ and the help centre says the setting will “highlight content in your AI Mode and AI Overviews experience”.² Placement on one surface, emphasis on the other, in both documents.

The setting is per-user. It does not move a site’s position for anyone who has not selected it, so it is not a ranking factor in the usual sense. A reader can select as many sources as they like, and Google reported that over half of its early Search Labs testers chose four or more.³ Selections are stored on the Google account, so they follow a signed-in reader between browsers and devices.²

The feature has moved quickly. It began as a Search Labs experiment on 26 June 2025,⁴ reached general availability in the US and India in English on 12 August 2025,³ extended to English-language users globally on 10 December 2025,⁵ opened to all languages Google Search supports on 30 April 2026, and reached AI Overviews and AI Mode on 27 May 2026.⁶ Google reported more than 345,000 unique sources selected in May 2026 and more than 600,000 by August.⁷

How do you set your preferred sources?

There are two routes, and they write to the same setting.

The first is inside the results page. Search for something newsworthy, and where a Top Stories block appears, a cards-star icon sits to the right of the header. Selecting it opens the source picker, where sources are toggled with a blue checkbox.²

The second is the standalone tool at google.com/preferences/source, reachable from Search personalisation settings. It lists current selections and allows searching for a site by name or domain. This is also where a reader confirms whether a given site is available to select at all.

Google notes that “sources that aren’t updated regularly may not be available”,² so a site that has stopped publishing can drop out of the picker.

Where do preferred sources appear?

Four placements, all visible only to the reader who set the preference.

• Top Stories. Selected sources appear more prominently when they have published fresh, relevant content for the query.³
• A “From your sources” section. Google describes a dedicated block on the results page, separate from Top Stories itself.³
• AI Overviews and AI Mode. Links from a selected source carry a “Preferred” label.⁶
• A developing-topic carousel. On some queries about developing stories, Google shows a prominent link carousel that also highlights preferred sources.⁶

Google Discover is not one of them. Google’s help documentation names Top Stories, AI Mode and AI Overviews as the surfaces source preferences affect, and does not mention Discover.² Coverage that groups the two together is reading across from the fact that both are personalised feeds.

Readers continue to see content from sites they have not selected. Preferred Sources adds emphasis rather than filtering everything else out.³

Which sites are eligible to be a preferred source?

Google’s stated bar is low: “Any website that publishes fresh content is eligible.”⁶

The one structural restriction is scope. Only domains and subdomains qualify, so example.com and code.example.com can be selected but example.com/blog cannot.¹ A publication that lives in a subdirectory of a larger site cannot be nominated on its own.

Check your own status by entering your domain in the source preferences tool. If it does not appear there is no application process and no report explaining the absence. Google has not documented how the pool of selectable sources is populated, which leaves publishers without a way to diagnose why a site meeting the stated criteria is missing.

How can publishers ask readers to add them?

Google documents three methods.¹ All three reach the same setting; they differ in cost and in how much of the reader’s journey stays on your page.

A deeplink. Point a text link or an image at https://www.google.com/preferences/source?q=example.com, replacing the domain with your own. This takes the reader straight to your entry in the source preferences tool. It works in newsletters and social posts as well as on-site, and it needs no JavaScript.

A downloadable badge image. Google publishes translated “Add as preferred source” graphics as a single archive, intended to sit alongside social follow buttons. These are ordinary images, linked with the deeplink above.

An embeddable JavaScript button. Added on 20 August 2026, this is a script tag plus a <div google-add-preferred-source-btn></div> container, and Google recommends it.¹ Clicking it opens a small Google window with a single Add button, then returns the reader to their place on the page.

The button is the best experience for a reader and the most expensive to install. The script is Google’s Subscribe with Google publisher library, so the two-line version pulls a substantial payload and needs several Google hosts allowed in your Content Security Policy. Measurements and the lower-cost manual initialisation mode are in Google Releases an Embeddable Preferred Sources Button for Publishers.

Whichever method you use, the ask only reaches people who already read you. Preferred Sources rewards an existing audience rather than building one, which places it alongside newsletter signups and social follows rather than alongside ranking work.

Can you measure Preferred Sources in Search Console?

No. Search Console has no Preferred Sources dimension, no search appearance value for it, and no mention of the feature in its performance report documentation. Impressions and clicks from a reader who has selected you are blended into ordinary Search data with nothing to separate them.

That leaves indirect measurement only. If you publish news, Top Stories performance and repeat visitor behaviour are the closest proxies, and neither isolates the effect.

Google’s one published figure is that “people are twice as likely to click through to a Preferred Source”.⁶ That is Google’s internal data, reported without methodology, sample size, or a definition of the comparison group. No independent study of Preferred Sources has been published, so there is no outside figure to check it against, and every claim about the feature’s effect currently traces back to Google. Treat the 2x figure as directional rather than as a basis for forecasting.

Preferred Sources and AI search

Whether preferred status affects which sources an AI answer draws on, or only how those links are presented, is the question publishers most want answered, and Google has not answered it consistently.

Every document that describes the surfaces separately describes the AI effect as emphasis. The May 2026 announcement says preferred sources are “clearly labeled to stand out” and that readers can “easily spot links” from sources they have selected.⁶ The developer documentation says content “can be highlighted with a ‘preferred’ badge”.¹ The help centre says the setting will “highlight content in your AI Mode and AI Overviews experience”.² None of them says a preferred source is more likely to be cited.

The product itself says something broader. The dialogue a reader confirms reads “Add [publication] as a Preferred Source to see more of their content on Google Search”, and the confirmation that follows reads “You’ll see more content from this source on Google Search”. Neither names a surface, and AI Overviews and AI Mode are Google Search rather than products beside it.

So Google promises readers more content across Search while telling publishers, surface by surface, that the AI effect is a badge. Both things cannot be precisely true, and Google has not reconciled them. Plan on the documented version, because it is the one written for publishers and the one that survives if the generous reading is wrong: treat Preferred Sources as a multiplier on AI Overviews visibility you have already earned rather than a route to visibility you have not. The work that earns AI citations is unchanged either way, and it is the same work that earns the preference in the first place.

Frequently asked questions

Does being a preferred source improve my rankings? No. The effect applies only to readers who have selected you, and Google describes it as a change to what those readers see rather than a change to ranking.

Can I pay to be a preferred source, or apply for it? No. There is no application, no approval process and no paid placement. Readers select sites themselves.

Do readers know they have selected me? Yes, and they can deselect at any time in the same tool. The “Preferred” label is visible only to that reader.

Does a reader who has already added me see the prompt again? No. A reader who has already selected your site gets no dialogue from the embeddable button, so it cannot work as a standing call to action for a returning audience.
