Google today updated its Search Central documentation for the preferred sources feature, publishing new guidance for web publishers on how to help readers designate their sites as preferred news outlets inside Google Search. The page, last updated April 30, 2026 UTC, formalises the toolset that publishers can deploy - deeplinks, downloadable button assets in 16 languages, and step-by-step instructions for placement alongside other social calls to action. The announcement comes as the feature, which first surfaced as a Search Labs experiment in June 2025, has now completed a full global rollout across every language where Google Search operates.

The timing matters. For publishers navigating a sustained period of traffic pressure driven by AI Overviews and algorithmic volatility, the preferred sources mechanism represents one of the few official levers Google has made available that puts audience development partially back in the hands of editorial teams rather than ranking systems.

What the documentation says

According to Google Search Central, the feature's core proposition is straightforward: "When a user selects your site as a preferred source, your content is more likely to appear for them during relevant news queries in 'Top Stories'." That sentence, simple as it reads, marks a meaningful shift in how Top Stories placements can be influenced. Traditionally, editorial teams had no direct way to signal to individual users that they should see their content more often. Algorithmic relevance, freshness, and authority scores determined the outcome entirely.

The updated documentation makes clear that eligibility is not universal. According to Google Search Central, only domain-level and subdomain-level sites qualify to appear in the source preferences tool. The examples given are explicit: https://www.example.com/ and https://code.example.com/ are eligible, but https://www.example.com/blog is not. Subdirectory-level sites fall outside the tool's scope entirely. This distinction has practical consequences for publishers who host their editorial content on a subdirectory rather than a separate subdomain - they cannot be added by users through this mechanism regardless of their content quality or publishing frequency.

The feature is available globally for queries that trigger the Top Stories feature, across all languages where Google Search is available. That worldwide scope reflects a process that took approximately 10 months from initial experimentation to completion.

A feature with a documented history

The journey to this documentation update began publicly on June 26, 2025, when Google announced a Search Labs experiment called Preferred Sources in English for users in the United States and India. PPC Land covered that launch, noting that the feature allowed users to click a starred icon next to Top Stories, then select publications by checking boxes in an interface that surfaces only outlets "actively publishing fresh content."

The formal rollout outside the Labs environment came on August 12, 2025. Google launched Preferred Sources in Top Stories with technical documentation and publisher resources, though users outside the United States and India encountered 404 errors when attempting to access preference pages through publisher deeplinks - a geographic limitation that frustrated international publishers attempting to promote the feature to their own readers.

Global expansion arrived on December 10, 2025, when Google announced the worldwide rollout. According to Nick Fox, Senior Vice President of Knowledge and Information at Google, who published the announcement via LinkedIn, the feature expanded to all Search languages. The engagement data attached to that announcement was notable: people are 2 times more likely to click through to a site after marking it as a preferred source, according to Fox. During limited testing beginning in August 2025, users had already selected nearly 90,000 unique sources, ranging from local blogs to major international news outlets.

Today, Fox posted again on LinkedIn with an updated framing of the same metric. According to his post, "people are 2X more likely to click through to a site after marking it as a Preferred Source." He also confirmed that Preferred Sources is now expanding to all Search languages worldwide, describing the process for adding sources in three steps: searching for a news topic or Top Stories, tapping the star icon next to Top Stories, and then adding favorite outlets by checking a box.

The most technically actionable element in the refreshed documentation is the deeplink URL structure. According to Google Search Central, publishers can construct a direct link to their site's listing inside the source preferences tool using the following format:

https://google.com/preferences/source?q=Your_Website_URL

For a site at https://example.com, that becomes https://google.com/preferences/source?q=example.com. The link takes users directly to the publication's entry in the preferences interface, removing the need for users to discover and navigate to the tool independently. Publishers can embed this deeplink in social media posts, email newsletters, and on-site promotional placements.

The second distribution method involves downloadable button assets. Google provides design files in 16 languages: Danish, English, Estonian, Finnish, French, German, Hebrew, Hindi, Japanese, Korean, Portuguese (Brazil), Russian, Spanish, Swedish, Turkish, and Ukrainian. Publishers may also design their own buttons rather than using Google's assets, as long as the link destination remains the same. According to the documentation, this button should sit alongside other social calls to action on the publisher's site - the kind of placement typically used for social media follow buttons or newsletter signup prompts.

The documentation includes an important disclaimer: these methods are described as examples of how publishers can build audience and help people find their site as a preferred source. According to Google Search Central, "It's not required to do them in order to appear as a preferred source." The preferred sources tool operates as a supplementary layer on top of Google's existing ranking systems, not as a replacement for content quality signals.

The "From your sources" display

When users have selected preferred sources, the effects surface in two ways inside search results. According to Google's documentation, selected outlets "appear more frequently in Top Stories or in a dedicated 'From your sources' section on the search results page." The second display mode - the dedicated "From your sources" box - is a distinct unit that sits alongside, rather than inside, the main Top Stories carousel. Users continue seeing content from other outlets regardless of their selections, so the feature does not create a closed, personalised feed. It adds weight and dedicated placement for chosen publishers while maintaining algorithmic diversity in the broader results.

This architecture is deliberate. Google has been careful to frame the tool as a personalisation layer, not a bypass of its editorial ranking systems. Sources that are not updated regularly may not be available for selection, according to documentation published during the August 2025 rollout. That filter - applied automatically by Google - means publishers with inconsistent publication schedules may be excluded even if users attempt to search for them.

What it means for the marketing and publishing industry

The practical impact of this documentation update is most visible when viewed alongside the pressures publishers have been navigating since 2024. Google Discover became the dominant traffic source for news and media websites in research published August 2025, accounting for two-thirds of Google referrals analysed across 2,000 global news and media sites. Traditional Google Search traffic, by contrast, dropped from roughly 51% to 27% of total referrals between 2023 and 2025.

Against that backdrop, Preferred Sources offers a direct audience relationship tool at a structural level that publishers have rarely had access to inside Google Search itself. The 2X click-through rate increase documented during testing is a meaningful figure - not because it restores lost traffic in absolute terms, but because it reflects a qualitative shift. Users who actively designate a publication as a preferred source are demonstrating explicit intent, which produces different engagement behaviour than passive algorithmic delivery.

Google expanded customisation features alongside new publisher AI partnerships in December 2025, framing Preferred Sources as part of a broader strategy to strengthen publisher relationships. At that same moment, AI-powered article overviews were being tested with select large publishers - a pilot that created a two-tier dynamic where established brands gained experimental features while smaller outlets continued absorbing traffic declines from AI Overviews without equivalent financial arrangements.

The updated Search Central documentation does not change that structural context. What it does is lower the activation barrier for publishers of all sizes to begin directing existing readers toward the preference tool. A local news site with 50,000 monthly readers can now add a single button to its homepage and a deeplink to its weekly newsletter and begin accumulating preferred source designations at no technical cost.

Nick Fox addressed publisher-Google traffic dynamics in December 2025, emphasising that "the primary" way Google partners with news organisations is "driving clicks" rather than content licensing. Preferred Sources operationalises that framing at the user level: the mechanism keeps users within Google's search interface for discovery, but the eventual click - once the preferred source appears in results - goes to the publisher. The 2X multiplier on click-through rates suggests that active designation by users creates a stronger motivation to visit the source than passive exposure in Top Stories alone.

For marketing professionals managing publisher clients or running content-driven campaigns, the documentation update has a clear implication: the deeplink and button assets are now stable, globally-available tools that belong in any publisher's audience development checklist. The infrastructure has been in place since December 2025. The April 30, 2026 documentation update signals that Google considers the feature mature enough to warrant formalised, language-specific promotional materials at global scale.

Google's AI Mode in Chrome now opens publisher links side by side as of April 16, 2026, a separate development that further reshapes how publisher visits are measured. Combined with Preferred Sources, the picture emerging is one where Google is incrementally adding layers of user intent and engagement signalling around news content - while the underlying question of how algorithmic changes affect organic reach for publishers without explicit user designation remains unresolved.

The freshness requirement embedded in the source preferences tool also acts as an indirect content strategy signal. Publishers that publish irregularly may find themselves excluded from user selection entirely, regardless of the quality of their existing archive. Consistent publication cadence becomes a prerequisite for participating in the feature at all.

Timeline

Summary

Who - Google, through a Search Central documentation update and a LinkedIn post by Nick Fox, SVP of Knowledge and Information at Google, directed at web publishers and website owners globally.

What - Google today updated its official guidance for the preferred sources feature, publishing the deeplink URL format (https://google.com/preferences/source?q=Your_Website_URL), downloadable button assets in 16 languages, and eligibility requirements for publishers who want to help readers add them as preferred news sources in Google Search. Only domain-level and subdomain-level sites are eligible; subdirectory sites are excluded. The feature is available globally for all queries triggering Top Stories in every language Google Search supports.

When - The Search Central documentation was last updated April 30, 2026 UTC. Nick Fox's LinkedIn post confirming expansion to all Search languages worldwide was published the same day.

Where - The guidance lives on Google Search Central. The Preferred Sources feature operates inside Google Search's Top Stories unit and a dedicated "From your sources" display on search results pages, available globally across all supported Search languages.

Why - Google positioned the update as a tool for publishers to build direct audience relationships inside Search, citing internal data showing users are 2 times more likely to click through to a site they have actively marked as a preferred source. For the marketing and publishing community, the significance lies in the formalisation of a concrete, low-technical-barrier mechanism for influencing search result visibility at the individual user level - at a time when broader algorithmic and AI-driven changes continue to shift traffic patterns in ways publishers have limited ability to control.
