Google opens the Preferred Sources button to sites, Discover gets conversational customization
Publishers can now embed a button on their own pages asking readers to select them as a Preferred Source. Per Google, more than 600,000 unique sources have been selected so far. The same announcement adds customizing the Discover feed in your own words and topic selection for audio briefings in News.
Personalization across three surfaces
Per a Google announcement dated August 20, 2026, three changes are arriving that give users more control across Search, Discover and News.
The most notable one concerns publishers directly: an embeddable button for Preferred Sources. The publisher places the button on their own page, and when a reader taps it they add the site as a preferred source and return to the publisher's page.
Search Engine Land covered the Discover conversational customization the same day and noted that for content teams it could help surface niche topics and help readers find publisher content.
How the button works and how the feed adapts
The function of the Preferred Sources button is clear: a reader adds a site to their preferred sources list in one click. Per the announcement, those sources appear more frequently in Top Stories, AI Overviews and AI Mode. Google states that more than 600,000 unique sources have been selected to date. The code for the button is available to developers through Google Search Central documentation.
On the Discover side, feed customization works like this: the user taps the three dot menu in the feed and writes, in their own words, the topics they want to see more or less of. The examples in the announcement are everyday language: kitchen renovation ideas that are eco friendly only, or weekend road trip videos with no camping. Per Google the feed adjusts on the fly and remembers the requests. The feature arrives in the Google app in the coming days.
The third item is audio briefings in Google News. Users can select specific topics for their daily audio briefing, and per the announcement briefings come with clear source attribution and links to full articles. Android is the platform named.
Per the Search Engine Land note, the coverage does not share rollout timing, country or language scope, and makes no definitive statement about traffic impact.
Asking for visibility from the reader, not the algorithm
The assessment in this section is ours. For years visibility was a one way negotiation: you produced the content and the algorithm decided. The Preferred Sources button adds a second channel to that negotiation. Once a reader says they prefer you, part of the ranking argument is skipped.
The logic resembles an email newsletter. A subscription is a bond independent of the platform. The difference here is that this bond operates inside Google surfaces: the user sees you more often in their own results.
The second point is who this actually helps. A reader choosing a site as a preferred source is a serious statement of trust. To be able to ask for it you need regular, recognizable content that people genuinely follow. For a site that publishes a corporate notice once a month, this button changes nothing.
Third, the two way effect of Discover customization. As users describe their interests more precisely, room opens for niche content; but the same mechanism filters out content that falls outside those interests faster. Discover can become a harder place for generic content.
Fourth, the consistency of direction. We are in a period where control is increasing on both the publisher and the user side; the debate around OpenAI saying robots.txt rules may not apply to the ChatGPT fetch bot was the other end of the same heading. Who holds control remains the question of the year.
What it means for businesses in Türkiye
The assessment below is not in the sources, it is our reading. The announcement states no Türkiye specific scope or timeline.
Few businesses here produce content regularly. This news gives exactly that minority an advantage: a brand publishing weekly or daily, with a real bond to its readers, gains a tool to carry that bond into search results.
Practically, if you have a blog or a news section it makes sense to think now about where the button goes on the page. The natural spot at the end of an article is also the moment a reader who finished the piece is closest to declaring a preference. Asking for it in the same place and the same sentence as the newsletter signup is possible too.
The second point is setting the right expectation. This button is not a ranking guarantee; it works within the results of the user who chose you. Its scale equals your readership. Valuable for a small but loyal audience, meaningless for a wide but indifferent one.
Third, Discover. It is a serious traffic source for many publishers here. Users being able to narrow the feed in their own words can favour publications with a clear topic focus. Being recognizable in one area becomes more valuable than a mixed feed touching every subject.
Fourth, measurement. This kind of preference may not show up in traffic immediately. Brand searches, direct visits and returning visitor share are better indicators of the effect than clicks.
The UNALSOFT take
On the brand management side we have long told clients the same thing: visibility borrowed from a platform and a bond earned from a reader are different things. This button is one of the first concrete tools carrying the second into the first. Installing the tool is not enough though; to ask for it you first need a publishing rhythm worth following. A brand that produces one genuinely read piece a week creates the place for that button by itself. Building a following rather than chasing a ranking remains the sturdier strategy.
