Friday’s numbers keep arriving from the party they flatter: Google’s own count of Preferred Sources adoption, and a vendor study on OpenAI’s citation edge sold by two firms in the AI-visibility business. Meanwhile Microsoft and Google strip advertiser controls while shipping the tools to measure what the loss actually costs.
The Numbers Come From Who Benefits: Preferred Sources And OpenAI’s Citation Edge
Google says Preferred Sources selections tripled and starred sources get clicked twice as often. Two vendors that sell AI-visibility software say OpenAI’s licensing deals lift ChatGPT citations 48 percent. Neither claim carries independent verification.
- Google’s Preferred Source Button Now Keeps Readers On The Page Google redesigned the Preferred Source embed button so a reader who confirms returns to the exact spot on the publisher’s page instead of being sent to Google. The company says people have now picked more than 600,000 unique sources, roughly triple the 200,000 it reported in May 2026, and that readers are twice as likely to click through to a source they have starred. Both figures come from Google rather than independent measurement, and Google has published no participation count for outlets, only for readers, so search teams cannot tell whether the 600,000 selections concentrate among a handful of major publishers or spread across the long tail competing for Top Stories placement.
- Vendor Study Ties OpenAI Deals to 48% More ChatGPT Citations Press Ranger and OtterlyAI analysed 129.3 million citations across seven AI search platforms using June 2026 data, matched against confirmed publisher licensing deals, and found pages from OpenAI-licensed publishers earning 48% more ChatGPT citations than unlicensed ones, with OpenAI-exclusive licensees up 112%. The more interesting half of the result runs the other way: Google-licensed publishers were cited slightly less often in AI Overviews than unlicensed publishers, and Perplexity’s licensed publishers landed at parity, leaving OpenAI as the only licensor showing a clear home-platform advantage. This is a self-published study from two companies that sell AI-visibility products, announced through a press release and not independently replicated.
Removing The Cap, Adding The Ruler: Microsoft And Google Retool Ad Controls
Microsoft strips the CPC ceiling from new automated bid campaigns while Google ships testing tools meant to help AI Max advertisers see what a similar loss of control actually costs them.
- Microsoft Advertising Drops Max CPC From New Automated Bid Campaigns From October 1, advertisers creating new standalone campaigns on Maximize Conversions, Maximize Conversion Value or Maximize Clicks will no longer be able to set a Max CPC cap. Existing campaigns keep their current settings, and portfolio bid strategies, Target Impression Share and enhanced CPC are unaffected. Microsoft’s stated reason is that CPC caps override what the bidding strategy is told to optimise for and cause spend-pacing irregularities, and it points advertisers toward target CPA and target ROAS instead.
- Google Gives AI Max Advertisers Tools To Test Before They Commit Google is rolling out new AI Max testing and planning tools in September: multi-campaign A/B testing that compares budgets and ROI targets across several Search campaigns at once rather than one at a time, AI Max experiments that now support brand and location controls, and a Performance Planner update that forecasts the outcome of bidding and budget changes with one-click apply. The measurement tooling arrives in the same month advertisers are being moved onto the thing it measures.
A Fault Nobody Can Locate: Google’s Favicons Go Missing
Site owners watched their icons vanish into Google’s default globe days before a spam update, with no way to tell whether the fault sits on their end or Google’s.
- Google Favicons Vanish From Search Results, Fix May Be Rolling Out A spike of complaints documented site favicons being replaced by Google’s default globe icon in Search results, with roughly seven reports arriving directly and many more across Google’s Help Forums, X and Bluesky. The reports began a couple of days before the August 2026 spam update and are likely unrelated to it, though the timing guarantees some site owners will read one as the other. Google’s Rajan Patel said the team is looking into it, and at least one flagged example had already reverted by the time the reports were written up.
Today’s Quick Hits
- Mueller Explains Why Google Skips Some Update Announcements John Mueller told Eli Schwartz that Google runs small core and algorithm updates constantly without announcing them, publicising only the larger ones so site owners can tell a Google-caused change apart from a self-inflicted technical problem. He called the balance between transparency and creating unnecessary worry a persistent challenge.
- Google Tests Reviving View Counts On Business Profile Posts Google appears to be testing the return of Posts Insights inside Google Business Profiles, showing a people-viewed count on a post. The original feature launched in 2018 and Google sunset it in January 2023, leaving local businesses with no native measure of whether a post was seen at all.
- Google Ads Tests Enhanced Matching For Customer Match Lists A new Customer Match option called Enhanced Matching expands audience reach by matching an advertiser’s consented user lists against publishers’ consented lists where those are available. The membership duration caps at 60 days, well short of the 540-day standard elsewhere in Customer Match.
