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

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.

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.

It's annoying that GSC and Bing Webmaster tools use opposite blue/purple for colouring clicks / impressions, so I made a Chrome extension that flips Bing's colouring to give it parity with GSC. Enjoy the freed up 0.1% brain RAM. chromewebstore.google.com/detail/bing-...
