Answer first: Google Preferred Sources is a choice a reader saves in their Google account. It is not a switch that puts a UK or Isle of Man firm into AI Overviews for every searcher. Google’s publisher guide says that when someone selects your site, your content is more likely to appear in Top Stories with a preferred badge, and that in AI Mode and AI Overviews it can be highlighted with a preferred badge for those users. The source is the domain or a subdomain, not a folder such as /blog/. A site that is not updated regularly may not appear in the picker. The button and the deeplink are optional. A badge is still not a citation, a click, or an enquiry. Recheck the pages below before you brief anyone from a label. This article records them for a reader on 17 October 2026.

What is a preferred source?

A preferred source is a site a person has chosen to see more often. Google’s publisher guide, last updated 18 September 2026 in the copy recorded here, says two different things, and they are not the same strength:

  • In Top Stories, content from a selected site is more likely to appear, highlighted with a preferred badge.
  • In AI Mode and AI Overviews, content can be highlighted with a preferred badge for users who have selected that site.

“More likely” and “can be highlighted” are Google’s words. Neither sentence says the site will be cited, that every query will show the badge, or that a person who never selected the site will see it.

The reader-facing Preferred Sources help says the same preference covers Top Stories, AI Mode, and AI Overviews. Selecting a source in one place also tailors the others. If the person is signed in when they save the setting, Google says it stays with that Google account across browsers they sign in to. A private window, or a colleague’s phone, is not that account. A missing badge there does not mean the selection failed.

Top Stories itself is conditional. The help page says that section may appear when Google detects a news-oriented query, and that automated systems match the search with relevant, high quality, and fresh content. After a person reloads, Google says they will find the selected sources more often in Top Stories when those sources publish fresh content related to the search. A query for a boiler repair in one town is not, on that page, described as a Top Stories query. Do not treat a missing news box on a local service search as a broken preference.

Who has to select the site?

The reader does. Google’s steps are: open Google, go to Search personalization, then Source preferences, search for the source, and tick it. From a Top Stories box the path is the star control, then the checkbox, then Reload results. There is no Search Console switch that selects your firm on behalf of the public.

Google’s 15 October 2026 post says the number of people using Preferred Sources has grown by more than 7x since the start of the year. The 27 May 2026 post says Google has found that people are twice as likely to click through to a Preferred Source, and that people had already selected more than 345,000 unique sources. Those are Google’s figures about its own product. They are not a click-through rate for your host, and they are not a forecast of enquiries. The May post also says any website that publishes fresh content is eligible. Read that next to the help-page tip: sources that are not updated regularly may not be available. The pages recorded here do not define “regularly” as a number of days. Do not invent a posting calendar, and do not publish a thin page every morning to chase the picker.

Which address can be a source?

Google says only domain-level and subdomain-level sites can appear in the source preferences tool. The publisher guide’s examples are https://www.example.com/ and https://code.example.com/. A subdirectory such as https://www.example.com/blog is not eligible.

For a small firm that means the host, not the service URL. Customers may use the apex host, the www host, or both. Google’s examples treat www.example.com as a site and a different subdomain as another site. The guide does not say whether your apex and www hosts are one row or two. Search the tool for the host customers type, and write down the row you actually see. Do not add a second website so that a folder can have its own badge.

A path is still the thing a supporting link points at. The preference is the host. The page that has to answer the question is the URL. Those are different jobs.

What has to be true before a badge can show in an AI answer?

Two Google pages set the gate, and a badge does not replace either of them.

The publisher guide says preferred sources can appear in AI Mode and AI Overviews in the languages and locales where those features are available. To be eligible for display as a preferred source in those features, the site must be included in Search generative AI features in Search Console. That setting is the include or exclude guide. Include is the default. Exclude, on Google’s control page, prevents the site’s links and content from appearing in AI Overviews, AI Mode, and generative AI features in Discover, and it says you will not receive traffic or impressions from those features. A preferred badge inside an AI answer, for a property set to Exclude, would contradict that page. Read the property that matches the host before you blame the button.

Google’s optimisation guide says the same inclusion rule more broadly: besides the ordinary Search technical requirements, a site must be included in Search generative AI features to be eligible for display in generative AI features on Google Search. It also says that meeting the requirements still does not mean Google will crawl, index, or serve the page.

The AI features guide is the other half. A page shown as a supporting link in AI Overviews or AI Mode must be indexed and eligible to be shown in Google Search with a snippet. There are no additional technical requirements, and no special schema. The guide’s copy recorded here was last updated 10 December 2025, and it does not mention Preferred Sources. The preference does not retire that eligibility sentence. How to read the indexed status of one URL is the URL Inspection guide.

The feature is described as global for Top Stories, in the languages where Google Search is available. The help page recorded here does not describe an Isle of Man mode, or a UK-only mode. A .im host and a .co.uk host are still different hosts in the picker. Search each one you actually serve.

What did Google announce on 15 October 2026?

The 15 October post is about how links are shown. It does not publish a new way to apply for a citation. Five items are on the page:

  1. Inline links. Google says these are links inside words or phrases in an AI response, that it has made continued and substantial increases to their presence, and that it is showing them higher up more frequently. The post does not give a count, and it does not say a firm can choose the anchor.
  2. A test for official pages. Google says that sometimes only one or two official places exist for a task or a fact, and that it will test a display that puts those links in a section at the top of a response, with context about why each link is useful. “We’ll be testing” is the tense on the page. There is no form to join, and the post does not say a Business Profile, a schema type, or a Preferred Sources tick creates that section.
  3. Timely-article carousels. Google says it is starting to roll out the prominent carousels for timely articles to additional locations and languages. The carousels also highlight Preferred Sources. The post does not name the United Kingdom or the Isle of Man as a finished market. A service page that has not changed is not what that sentence is about.
  4. Links at the end of some responses. Google says it is making those links more prominent, with image thumbnails and a more clickable design. A thumbnail is not a reason to move the only clear fact into a picture. The AI features guide still says important content should be available as text.
  5. Creator names on video results. Google says that, in the week of that post, it started testing clickable creator and publisher names on video results in AI Mode, linking to Search profiles. The Search profile help says Search profiles are currently available in Canada, India, and the United States. It does not list the United Kingdom or the Isle of Man. A firm in either place should not spend the afternoon on a profile because a video test was announced. The test is also about video results, not about the ordinary service page.

None of the five items is a measurement. Impressions inside AI Overviews and AI Mode remain the Generative AI performance report. Google’s report help does not mention Preferred Sources, a preferred badge, or a source-preference filter. The report counts how many times a link was shown. A badge on one signed-in person’s screen is not a column that page documents. Do not add the two ideas into a single number.

A different label is easy to mix up with the badge. The 27 May post says Google is adding a Highly Cited label to more web article links, for articles that many other stories have cited. That label is not Preferred Sources, and there is no control on your site that turns it on. Google’s optimisation guide says seeking inauthentic mentions is not as useful as it might seem, because ranking systems focus on high-quality content and other systems block spam. Buying a ring of write-ups so a page can wear that label is the thing that sentence is warning about.

Does the button select the site for the reader?

No. The publisher guide says the button and the deeplink are ways to help readers find the site in the tool. It also says you do not have to use them in order to appear as a preferred source. If the site does not appear when you search the tool, a button on the homepage does not create the row.

Google’s recommended install is two lines. The script loads the library. The empty element is where the button is drawn. Google says the button is translated for the reader, can return them to the page, and can be themed light or dark. The language follows the browser unless you override it. The guide does not say a UK firm must force a language code. Leave the override out unless you have a reason that is on that page.

``html <script async src="https://news.google.com/swg/js/v1/publisher.js"></script> <div google-add-preferred-source-btn></div> ``

If the CMS strips scripts, Google’s alternative is a deeplink. Replace the query with the host customers type. Google’s own example is a bare domain, while the format line says to use the site URL. Open the link yourself and read which row the tool shows before you put it in a footer.

``html <a href="https://www.google.com/preferences/source?q=example.com">Add as Preferred Source</a> ``

Google says the deeplink can also sit in a social post, an email, or a promotion. That is still a request that the reader confirm the selection in Google’s tool. It does not select them, and it does not change what a logged-out searcher sees.

Check the host in the tool before you embed anything. The publisher guide’s instruction is to enter the site in the tool’s search box. If the row is there, the button is optional. If the row is absent, fix the reason you can actually read, which on the help page is that sources not updated regularly may not be available. Do not commission a plugin that promises the row.

What should a local firm still write on the page?

The preference does not write the page. Google’s optimisation guide says that for Google Search, AEO and GEO are still SEO: the generative features use the Search index. It also says there is no special AI file to add. An llms.txt file is ignored by Google Search. Keeping one for some other system is fine. It will not produce a preferred badge.

What the same guide tells an owner to do is the ordinary work. Unique, people-first pages. Facts in text. Headings a person can follow. Images and video that support the text, not replace it. Internal links to the pages that matter. Structured data that matches the visible words, with no special schema for these AI features. A clear coverage sentence belongs in that text. A Douglas firm that only works on the Island should not leave a line that reads as UK-wide attendance. How to shape the page around one question is the service-page guide.

Do not mint a URL for every town, or for every related question, because a carousel highlights preferred sources. The optimisation guide says that creating separate pages for query variations, mainly to manipulate rankings or generative AI responses, violates Google’s scaled content abuse policy. A preferred host with a stack of near-copies is still a stack of near-copies.

ChatGPT, Perplexity, Bing, Copilot, and Apple do not read this Google preference. Their crawler controls are the citations guide. A badge in one signed-in Google account does not travel.

What should I check on the day I look?

Do this on the host customers type. Write the date next to what you find.

  1. Open Google’s source preferences tool and search for that host. Record whether a row appears. If you use both apex and www, search both, and do not assume they are one source.
  2. If the row is missing, stop at the documented tip: sources that are not updated regularly may not be available. Do not invent a quota of posts.
  3. In Search Console, on the property for that host, read Settings, then Search generative AI. The publisher guide requires Include for a preferred badge in AI Mode and AI Overviews.
  4. If you add the button, use the two lines Google publishes, or the deeplink if the page cannot run the script. Open the deeplink and confirm the row before you publish the link.
  5. Open the service URL logged out. The answer a caller needs should be text. If you need the indexed reading, use URL Inspection, not the badge.
  6. Read the Generative AI performance report only as an impression report. It does not document a preferred-badge filter.
  7. Leave Search profiles alone unless the creation help page lists your country. The page recorded here lists Canada, India, and the United States.

What should I not claim?

  • That the button, the deeplink, or a selected source puts the firm in AI Overviews for everyone. Google describes the AI badge for users who selected the site.
  • That “more likely” in Top Stories is a citation, a click, or an enquiry. Google’s 7x figure and its “twice as likely” finding are about its own product, not your host.
  • That /blog/ or a single service page can be the preferred source. Google says a subdirectory is not eligible.
  • That the 15 October tests are a programme you can join, or that a schema type creates the “official page” section.
  • That a Search profile is available in the UK or the Isle of Man. The creation page recorded here does not list either.
  • That the Generative AI performance report counts badges.
  • That an llms.txt file, or any special AI markup, is how Google selects preferred sources. The optimisation guide says Google Search ignores those files.
  • A result, a town, or a before-and-after Halo has not published with evidence. This guide does not add one.

Where Halo fits

Halo’s search, AEO and content service covers the public page: the answer in the first screen, internal links, and structured data that matches the visible words. Preferred Sources sits in the reader’s Google account. The Include setting sits in the Search Console property you verify. Halo does not need either login to read the page.

To start, send the URL through the free AI audit. If you have already checked the picker, name the host you searched, whether a row appeared, and whether the property is Include or Exclude. Halo does not guarantee a badge, a citation, impressions, or enquiries.

FAQ

Does the Preferred Sources button put my page in an AI Overview?

No. Google’s publisher guide says the button and the deeplink help a reader select the site. They are not required for eligibility, and a selection does not place the site in an AI Overview for everyone. A preferred badge in AI Mode or AI Overviews is described for users who have selected the site. A supporting link still has to be indexed and eligible for a snippet, and Google says indexing and serving are not guaranteed.

Can a folder such as /blog/ be the preferred source?

No. Google says only domain-level and subdomain-level sites are eligible. The publisher guide’s examples are a host such as www.example.com and a subdomain such as code.example.com. A subdirectory such as example.com/blog is not eligible. The service page is still the URL that has to answer the question.

If the site is excluded from Search generative AI, can a preferred badge still appear in AI Mode?

The publisher guide says the site must be included in Search generative AI features in Search Console to be eligible for display as a preferred source in AI Mode and AI Overviews. Google’s control page says Exclude keeps the site’s links and content out of those features. Read the property setting before you treat a missing badge as a broken button.

Does the Generative AI performance report count preferred badges?

No. That report’s help page does not mention Preferred Sources or a badge filter. It describes impressions: how many times a link to the site was shown in AI Overviews or AI Mode. A badge on one signed-in person’s result is not a metric that page documents.

Can a UK or Isle of Man firm create the Search profile named in the 15 October post?

Not from the help page recorded here. Google’s Search profile creation page says Search profiles are currently available in Canada, India, and the United States. It does not list the United Kingdom or the Isle of Man. The 15 October post says Google started testing clickable creator and publisher names on video results in AI Mode. That test is not a setup guide for a UK or Isle of Man service page.

Is a missing result in the source search box a penalty?

Not on the pages recorded here. Google’s tip is that sources which are not updated regularly may not be available in the picker. The publisher guide tells you to check by searching for the site in the tool. It does not call a missing row a ranking penalty, and it does not publish a minimum update schedule.
