I got an email from a SearchNorwichXL sponsor today that said their teams unanimous feedback is that it was "the best conference that weve partnered with in the UK so far" and it made my day 🥲

Some assorted photos from SearchNorwichXL yesterday. Such a great event. Well done to @markwilliamscook.com and the team. Greatly enjoyed @divingfor.fun's "Angry German Man" rant about the state of the web - though it was more a call-to-action to build the web we want. ❤️ #SNXL

But wait until AI does respond to requests to verify -> Qwoted removes an "art therapist" who was widely quoted on psychological topics by news outlets, after her photograph and output are found to be AI-generated "‘Dr Eleni Nicolaou’ has appeared more than 30 times in the media in recent months..."

Do not underestimate the scale of this climate crisis. We are watching feedback loops accelerate, ice sheet collapse, ocean heat content, methane release, that could lock in irreversible warming. We have all witnessed the data, and it is not slowing down.

Be careful using LLMs to process log files. It is possible to exfil data by injecting prompts into HTTP headers to get LLM to call a URL controlled by attacker with data in query string.

⚠️ Massive change by Google: We are likely to see 100% AIOs within "People Also Ask" answers in the next few weeks 🤖 @alsoasked.com took a sample of 19.2M English language made in 2026, 97% of PAA answers in the first week of September are AIOs. Seems likely we are on track for 100% shortly.

Another fantastic article from @bngsrc.bsky.social, this time about making decisions from false precision with attribution data. Essential reading for those tricky client conversations: www.searchenginejournal.com/when-attribu...

When Attribution Looks More Precise Than The Data Behind It
Attribution reports look precise, but much of that data is modeled, not measured, and confusing the two can quietly misallocate marketing budget.

MRW to 'pSEO' click/impressions hype on LI.
A two-panel meme featuring Christian Bale as Patrick Bateman from American Psycho, wearing glasses and a suit in an office setting. In the top panel, he smirks with white text reading "IMPRESSIVE, VERY NICE". In the bottom panel, he leans forward with a critical, squinting expression and gestures with his hands, with text reading "NOW LET'S SEE TRAFFIC IN 6 MONTHS".

There are lots of things I miss about "old internet", but another one was that sweet spot where we didn't really need MFA and it was okay to just kinda stay logged into everything all the time.
