Add as Preferred Source Button & Popup for Google (SEO & AI Overviews)

Description

Audit Preferred Sources eligibility, button setup and fallback links locally. Chrome companion checker. Add as Preferred Source Button & Popup for Google is a Chrome Site Checker that audits the Google Preferred Sources implementation on the page you are viewing. This free Chrome companion reports domain eligibility, SDK and button setup, fallback-link health and practical fixes in one click. Google's Preferred Sources lets readers choose publications they want to see more of. Google says fresh and relevant content from a selected source is more likely to appear in that reader's Top Stories and may receive a Preferred Sources badge in AI Mode and AI Overviews. Indirectly, correct use of the Preferred Source button should enhance SEO and organic visibility in search. Google has reported that people who select a source are about twice as likely to click through to it. This is a reader-level preference, not a site-wide ranking factor or a guarantee of rankings, traffic, inclusion or AI citations. Publishers can provide Google's official popup button or a direct preferences link, but the implementation still needs checking after it is added. WHAT IT DOES 1. Eligibility check: classifies the current host as a domain, www domain or subdomain and flags common publication paths such as /blog. Preferred Sources applies at domain and subdomain level only. The checker links to Google's source tool because it cannot confirm automatically whether Google recognises the site as a source. 2. Implementation detector: scans the current page and reports a checklist: • SDK loaded: is Google's publisher.js or publisher.mjs present, and is it async? • Mode: is the page using automatic rendering or manual control? • Button element: is google-add-preferred-source-btn present, visible and populated with Google's button iframe when available? • Deeplink fallback: is there a valid link to google.com/preferences/source, and does its q value match the site? Failed checks include plain-English fix guidance and ready-to-paste examples. 3. Add-page link: the Add as preferred on Google action opens Google's own source preferences page for the current domain in a new tab. You complete the add on Google's page. The extension does not click, fill or automate Google's interface, and it cannot detect a completed addition. 4. Copy embed snippet: copies the standard automatic-mode embed plus a no-JavaScript fallback link, personalised to the current domain. WHO IT IS FOR Website owners and SEO consultants checking Preferred Sources readiness, agencies reviewing client deployments, and publishers verifying an embed after installation. WHY CHECKING MATTERS A missing async attribute, hidden button, mismatched fallback domain or subdirectory assumption can leave a publisher with an implementation that looks complete but does not provide the intended reader journey. The checker turns those technical details into a short checklist and specific next actions. It does not estimate rankings or claim that Google has accepted the site. LOCAL-FIRST PRIVACY The page scan runs in the browser and does not modify the page. The extension stores audit metadata in chrome.storage.local for the user's device. It does not transmit, sync or upload that history, and there is no analytics service. The extension does not make background requests or fetch scan data to a service. Clicking Add, Verify, the generator or an Opace link opens the chosen destination in a new tab. Those user-triggered navigations are visible actions, not silent collection. The extension does not claim that a source was added successfully.
