Anthropic launches Claude Opus 5, Facebook Marketplace gets its own app & more
This week's highlights across Search, Social, PR and AI.
Search
1. Google still ranks heavily AI-flagged pages (but they sit lower)
New research from Ahrefs found that pages scoring higher on its AI detector tend to sit lower in Google’s results. The average AI detector score rose from 27.1% at position 1 to 30.9% at position 10. Pages with the highest AI scores were also slightly less likely to appear in Google’s index at all. That said, pages scoring 100% AI-generated still turned up in top-three positions, and Ahrefs describes the difference in ranking as “gentle” rather than decisive.
The key takeaway is that Google doesn’t appear to be running a simple AI content penalty. The more plausible explanation is that heavily AI-generated pages are also more likely to be lower-quality content overall, and quality is what Google is actually evaluating. A high detector score is a reason to look more closely at a page, not proof that Google has penalised it.

Social
2. The EU escalates its TikTok probe over teen privacy
The European Commission has announced preliminary findings against TikTok under the Digital Services Act, accusing the platform of failing to adequately protect the privacy and safety of users under 18. TikTok could face a fine of up to 6% of its global annual revenue if the issues are not addressed. TikTok disputed the findings, pointing to more than 50 preset privacy and safety features on teen accounts.
This is the latest in a pattern of escalating regulatory action against social platforms in Europe, and it lands at a moment when child safety online is under intense legislative scrutiny across multiple markets.
The direction of travel is worth watching for brands running campaigns on TikTok. Stricter default settings for minors would shrink the addressable audience for content that relies on broad algorithmic distribution.
3. Meta gives Facebook Marketplace its own dedicated app
Marking Marketplace’s tenth anniversary, Meta has launched Seller, a standalone iOS app for people who sell on Facebook Marketplace regularly. It brings together AI-powered listing creation, a unified inbox, inventory management and performance insights in a single place, syncing automatically with existing Marketplace accounts.
Facebook’s resale economy has quietly become one of the platform’s stickiest products, particularly with younger audiences, and Seller suggests Meta is building toward something considerably more ambitious.
4. Facebook is testing a full TikTok-style video feed
Facebook head Tom Alison also announced the platform will test a “reimagined experience” for a subset of users that opens directly into a full-screen video feed the moment the app is launched. The test will initially roll out to international markets with “a noted preference for video content”.
After previously claiming TikTok was chasing Facebook rather than the other way around, it seems Meta are now the ones playing catch-up.
5. The creator economy’s middle class is here
Quitting your job to become a full-time content creator is starting to feel like a realistic career pivot for a growing number of young workers. The numbers back it up, with microinfluencers averaging a 3.2% engagement rate, nearly triple that of accounts with over a million followers, and brands are shifting budgets accordingly.
It’s not all sunshine and roses, though. Around 57% of full-time creators earn below a living wage, income can swing wildly month to month, and the whole model sits on infrastructure creators don’t control.
PR
6. Coca-Cola rebrands by becoming more itself
Coca-Cola has rolled out a new global visual identity, built around a single creative brief: make Coca-Cola more Coca-Cola. The refresh simply amplifies what already exists (and works), keeping the Spencerian script, the red and white palette, the Dynamic Ribbon and the Arden Square.
Coca-Cola Zero Sugar gets the most visible change, with a black Dynamic Ribbon on cans and a black bottle cap on plastic bottles to help it stand out from the original.
The strategy is pretty solid proof that when you own visual assets that have been recognised for generations, the smart move is often to lean in rather than replace.
AI
7. Anthropic launches Claude Opus 5
Anthropic has released Claude Opus 5, its most capable Opus model to date. On benchmark evaluations, Opus 5 tops the field on software engineering tasks, scoring more than double Opus 4.8 on Frontier-Bench while costing less per task.
Anthropic also says it’s the most aligned model the company has produced so far, with the lowest rates of deceptive behaviour in internal testing.
8. ChatGPT Health is now available to all US users
OpenAI has opened ChatGPT Health to all logged-in US users over 18 across its free and paid plans, following a test period that began in January. The feature allows users to connect personal health data from Apple Health, MyFitnessPal, Function, Epic and Oracle Health, and now lets that information inform general queries across all of ChatGPT rather than just a dedicated health hub.
The full rollout was announced the day after a Florida pastor filed a lawsuit against OpenAI, alleging ChatGPT gave advice that nearly cost him his life by suggesting he didn’t need to see a doctor.
OpenAI maintains its terms explicitly state the service is not intended for diagnosing or treating health conditions.
9. Private Claude shared chats ended up indexed by Google and Bing
A thread on Reddit revealed that a simple site-specific search could surface hundreds of Claude conversations that users had shared via the platform’s share link feature. Wired confirmed the issue, finding the exposed pages lacked the “noindex” tag that tells search engines not to index them.
Content found in the results ranged from work notes and programming questions to explicit material and requests for legal advice. Anthropic responded by saying shared conversations are publicly accessible by design, and that the company does not share chat directories or sitemaps with search engines.
Both Google and Bing have since blocked the results.
