I wrote a little something on how to fix some of the (direct / none) traffic in #googleanalytics with the help of #gtm. https://t.co/qmpTFkQ0OR And I'd love to thank a few people for their help 1/2

The European Parliament has decided to say goodbye to Google.

Internal computers will now run the European Qwant search engine by default.

Now this case study, by @HundleyJake 📷, into the effects of LocalBusiness markup on Search, Maps, and AI, is one I can get behind.

Peer reviewed, comparable control groups, proper timelines, and statistical tests that made me learn something new. 💡

Anton Osika is also one of the faces of Balderton's "Built in Europe" campaign, launched the same day as the TanStack migration post.

Funding the commons should be one of the things we Europeans just do.

WordPress lightbulb moment. HTML-in-canvas is an elegant answer to @photomatt's push for 'weird themes' - they'll enable innovative/creative/unconventional etc UI on top of conventional surfaces, and even degrade gracefully.

MICROSOFT OPEN-SOURCED A GOVERNANCE LAYER FOR YOUR AI AGENTS

and it's exactly what agentic ai has been missing

here's what agent governance toolkit does:

▫️ intercepts every tool call in deterministic code before it hits the wire denied actions aren't unlikely, they're structurally impossible
▫️ yaml policy engine lets you allow, deny, or require human approval per action
▫️ zero-trust identity via spiffe/did/mtls no more 5 agents sharing one api key
▫️ 4-level execution sandbox with privilege rings so agents can't escape their scope
▫️ tamper-evident merkle audit logs for compliance and incident response
▫️ covers all 10/10 owasp agentic top 10 risks
▫️ works with langchain, crewai, autogen, openai agents sdk, semantic kernel, and more

one pip install...any framework...python, typescript, go, rust, .net all supported

because "please follow the rules" in a system prompt is not a guardrail...it's a suggestion

- 60-90% reduction and completely dependency-free
Repo → https://t.co/lDfjbsbPD5

3. Code Review Graph
- Claude reads only what matters using a Tree-sitter graph
- An unbelievable 49x token reduction on huge monorepos
Repo → https://t.co/xGn6Pp88yX

----

[ The god-tier stack ]
Pick 2-3 based on what’s draining you:
> Massive repo? Code Review Graph + Token Savior
> Heavy terminal output? RTK
> MCP data dumps? Context Mode
> Need an instant fix? Caveman + Claude Token Efficient

Most devs are bleeding tokens.

Run `/context` in a fresh session and watch the savings roll in 👀

🚨 Google just announced what it calls the biggest upgrade to the Search box in more than 25 years 👇

A new AI-powered Search box is designed to go beyond keywords and autocomplete. According to Google, it will:

✅ Dynamically expand so users can describe what they need in more detail
✅ Suggest better ways to formulate questions, beyond traditional autocomplete
✅ Support multimodal inputs, including text, images, files, videos, and Chrome tabs
✅ Let users continue from AI Overviews into AI Mode with follow-up questions
✅ Preserve context as users explore more deeply
✅ Still provide a range of Search results, according to Google

This is starting to roll out today in countries and languages where AI Mode is available.

Google also announced that AI Mode is now using Gemini 3.5 Flash globally as its default model.

Let's see how this impacts users search behavior, journey and ultimately, outcome towards sites.

Read announcement:

[Kevin_Indig @Kevin_Indig]

This is what Google should've announced at I/O today

[DEJAN @dejanseo]

System instructions for Gemini 3.5 Flash:

- Keep your responses concise.

- Keep your tone professional and avoid overconfident language, bragging, or
overclaiming success.

- AVOID using superlatives such as "perfectly", "flawlessly", "100% correct",
"Summary of Accomplishments" etc. to summarize your work for the user. Be
humble.

- AVOID over-the-top politeness or complimenting the user excessively.

- Format your responses in github-style markdown.

[Chris Long @chris_nectiv]

Heads up SEOs: Google has officially rolled out ads in AI Overviews + AI Mode.

There are now three "Sponsored" results at the bottom of many answers.

[JH Scherck @JHTScherck]

Everyone saying LLMs.txt is a waste of time because of the new Google GEO memo: Google is just one player in the ecosystem. Claude Code clearly leverages it when learning how to use an API. If you are focused on agentic enablement for APIs and MCPs, it's something to leverage.

[Arnout Hellemans @hellemans]

Yup, I'm sensing the same vibes....

[JH Scherck @JHTScherck]

Realize some folks on the Profound team follow me, and I mean no offense here — but it's clear that they have lost trust with the broader, non-enterprise SEO/AEO folks. They are quickly veering into BrightEdge territory in terms of overall vibe. They need to do something to win back the hearts and minds of the broader industry.

[TBPN @tbpn]

After several years of declining search traffic, Condé Nast CEO @rogerlynch has directed all the company's brands to operate as if search traffic to their properties will be zero.

He says the era of turning search and social media traffic into profitable businesses is gone.

And that if you run a media business that doesn't have an authoritative brand, a very strong niche, or a direct audience, you're going to be fighting hostile algo changes all the way down.

He describes a recent board meeting:

"We took a snapshot of search results from seven or eight years ago. And what you saw were a few sponsored links, then the ten blue links."

"Do the same search today, you get an AI overview, then you get rows and rows and rows of commerce links, then you get sponsored stuff."

"Each of the last three years, we would do our budgets, and we'd put forecasts in of search traffic declining. Because we'd seen the pattern of algorithm changes. And generally those algorithm changes were negative."

"Every year, our search traffic was down more than we had forecast. So last year I told our teams, 'Assume there's no search.' You have to have your businesses planned as if search is zero. We don't expect it to be zero, we expect it to be a single-digit percentage of our traffic."
