Google has published - and briefly removed - a policy document for Subscription Linking inside its Publisher Center Help area, with the page confirmed restored on June 25, 2026, outlining the conditions under which news publishers can participate in a feature that ties paid subscriptions to Google accounts.

What the policy document says

According to Google's Publisher Center Help documentation, the company developed the policies "to promote a trustworthy and secure environment for publishers using Subscription Linking." The document states that any publisher using the service must adhere to these policies. Google also reserves the right to change the policies at any time, and notes that the policy should be read alongside the Google APIs terms of service, which may contain additional rules on how to use the service.

On enforcement, the policy is direct. According to the documentation, "If violations of these policies are discovered, we may restrict or suspend your publication from Subscription Linking including but not limited to abuse or manipulation of the feature." That language places suspension decisions within Google's discretion, with no appeal process described in the published text.

The content policies section is brief but consequential. Subscription Linking publishers must follow the Google Search content policies - the same framework that governs organic search eligibility, not a bespoke set of rules for subscriber features.

The surfaces where Subscription Linking operates

The most operationally significant section of the document is the table of available surfaces. According to the policy, once a publisher implements Subscription Linking, it can be enabled across four distinct Google products, each governed by a separate control mechanism.

Google Search is controlled via what the policy calls a control to manage what publishers share with Google overall. AI Mode and AI Overviews use a search generative AI control. Generative AI features in Discover use that same search generative AI control. Gemini, listed as a separate surface, is controlled through Google-Extended - the robots.txt directive that publishers can use to manage how Googlebot-extended crawls their content.

The inclusion of AI Mode, AI Overviews, and Gemini as distinct Subscription Linking surfaces is notable. It means publishers participating in the feature need to evaluate their preferences across multiple AI-powered products, not just traditional search. PPC Land has tracked the expansion of AI Mode since its launch, which by May 2026 had surpassed one billion monthly users. The feature now runs on Gemini 3.5 Flash as its default model following the I/O 2026 upgrade on May 19.

The Gemini-Google-Extended pairing is technically distinct from the AI Mode and AI Overviews pairing. Google-Extended was introduced specifically as a way for publishers to block Gemini apps and Vertex AI from using their content for training and grounding, distinct from the standard Googlebot crawl. Its appearance as the designated control for Gemini within Subscription Linking means publishers must manage two separate opt-in/opt-out mechanisms if they want consistent behavior across Google's AI surfaces.

The disappearance and return of the document

The document did not stay live continuously. According to Search Engine Roundtable, which first covered the policy on June 23, 2026, Google removed the document shortly after the initial reporting. The page returned on June 25. The error page captured during the document's absence, displayed on the Google News Publisher Center Help interface, carried a copyright date of 2026 and displayed Google's standard "Sorry, this page can't be found" message with the explanation that "This page doesn't exist in Google News Publisher Center Help. It may be deleted because the feature doesn't exist anymore, or the URL may be incorrect."

The brief disappearance of a policy document that had just been publicly surfaced - and the absence of any explanation from Google about why it was removed or what changed between the two versions - is not unprecedented in the Publisher Center's history. Google removed Publisher Center's manual publication submission functionality in April 2024 and completed the full transition to automatically generated publication pages by March 2025. Throughout that process, documentation updates and reversals caused confusion among publishers. The pattern of publishing, retracting, and republishing policy content creates uncertainty for publishers who need stable reference material to make integration decisions.

The abuse reporting section of the policy includes a mechanism for publishers to flag misuse. According to the documentation, if a publisher suspects anyone is using Subscription Linking in an abusive or illegal manner, they should report it to Google immediately. The document as captured does not specify what constitutes abuse beyond the phrase "abusive or illegal manner," nor does it detail what form that report should take - and the reporting link itself was non-functional at the time the screenshots were captured.

Subscription Linking and the Reader Revenue Manager

Subscription Linking is technically a component of the Google News Reader Revenue Manager (RRM), a broader product designed to help publishers manage subscriber relationships and diversify revenue beyond advertising. PPC Land has covered the Reader Revenue Manager as a tool that lets publishers implement paywalls, collect contributions, run surveys, and build newsletter sign-up flows - all within a framework requiring a Google Publisher Center account.

The core function of Subscription Linking within that ecosystem is to allow readers who already pay for a publication to link their subscription to their Google Account. Once linked, those readers can receive highlighted content from their paid subscriptions in Google Search, Discover, and other Google products. The December 2026 addition of AI Mode and Gemini as Subscription Linking surfaces extends that visibility into Google's newest and fastest-growing search interfaces.

Google added five outbound link features to AI Mode and AI Overviews in May 2026, one of which was specifically a subscription highlight label. According to that announcement, early testing found that users were significantly more likely to click on links carrying the subscription label compared to unlabeled links. Publishers wanting their subscribers to benefit from that feature must submit their subscription infrastructure details through a Google form. The Subscription Linking policy document now formalizes the conduct requirements that accompany that integration.

The subscription surface table in the policy reinforces a pattern visible across Google's publisher tools: AI Mode and AI Overviews share a single control mechanism, while Gemini operates under a separate one. This mirrors the structure PPC Land identified in December 2025 when Google launched its subscription highlighting feature first in the Gemini app, with AI Overviews and AI Mode implementation to follow. The policy document now anchors that product distinction in formal terms and conditions.

Publisher Center context

The Publisher Center Help system where this policy lives has undergone substantial restructuring over the past two years. Google shifted to automated publication pages in March 2025, removing manual customization controls for logos, section management, and geographic distribution. Publishers lost the ability to restrict content to specific regions, submit RSS feeds, or control how publication titles appear in Google News. The Reader Revenue Manager functionality - which includes Subscription Linking - was retained as one of the few remaining active tool sets in Publisher Center.

That context matters for interpreting the new policy. Subscription Linking is among the most technically involved features still actively supported within a Publisher Center that has shed most of its configuration capabilities. The policy document formalizing its rules arrives at a moment when publisher relationships with Google's AI surfaces are under significant scrutiny. Independent publishers filed antitrust complaints with the European Commission in June 2025 citing traffic and revenue loss from AI Overviews. The UK Competition and Markets Authority imposed a conduct requirement on Google to give publishers opt-out controls for AI features. Against that backdrop, the expansion of Subscription Linking into AI Mode, Gemini, and Discover represents one of the few publisher-facing features where Google's AI integration is framed as an audience benefit rather than a source of traffic diversion.
