I like this proposal for a standardised machine readable format for publishing bot IP ranges.

Now more LLM crawlers publish their IP ranges, I've added a new tool that lets you spot check an IP address and see if it's a legit openAI/ ChatGPT, Perplexity or Claude one: tamethebots.com/tools/real-l... to go along with the Googlebot IP range one.

Definitely missed a clickbait title opportunity of "Vampires Hate this One Simple Trick" headline here

Had a great time when I managed to get to one of these, @optimisey.com is awesome, and if you can get to Cambridge, I'm convinced you'd have a great time.

Starting with Chrome 145, DevTools now lets you throttle specific requests instead of the whole page. It’s the ideal way to test how your app handles a single slow asset or API call → goo.gle/4aP1Tcc

i saw the interactive xkcd on hackernews and decided to make it render a real npm graph it uses webcontainers to `npm i {pkg}`, then renders the bricks based on the dep tree scaled by disk size

Lots of misinformation still flying around our SEO space so I dug into some of the possible causes and the current category conflicts and wrote them up following my presentation at Women in Technical SEO. www.womenintechseo.com/knowledge/ge...

That deep satisfaction when you finally find the right combination of flags to stop chrome automatically 307 redirecting http to https, so your testing tool doesn't quite work how you want. --disable-features=HttpsFirstBalancedModeAutoEnable (You would very much not want to do this IRL)

Parsley HTML, tasty. No wait 12 parsecs? No, parsing. Another great episode.

Your political affiliations shouldn't affect your ability to see AI being positioned as a political weapon. The Pentagon is threatening Anthropic bc it's unwilling to lift restrictions on use for mass surveillance of Americans or autonomous weapons not-a-robot.com/blog/ai-poli...

I have left so many ecommerce sites because I am trying to look at products and they force me to try and play some game to win a voucher code.

I've encountered many applications with poor INP due to long tasks that do not yield control to the browser I've written a guide with measurable examples comparing setTimeout, queueMicrotask, scheduler.postTask. It includes snippets to audit your projects joanleon.dev/en/yield-to-... #WebPerf

Html > CDN > markdown > llm > ?? All feels a bit W. Heath Robinson to me I think there are specific tasks markdown makes sense for, but it's never really a straight conversion (for example it does seem an efficient way to feed Dev doc context to coding agents) but it isn't a copy of a human page.

Just so people get a feeling how much 2MB HTML actually is, I made this (3MB+) monster: experiments.geekonaut.de/3mb-behemoth I know - nobody asked but here we are. You are welcome.

🕵️‍♀️ Does Google cut off file content beyond 2 megabytes? The reality is messy. Google does use some scary wording in their documentation, and it seems to impact some users. But I've not seen a script 2 MB limit applied in all cases. www.debugbear.com/blog/googleb...

We’re excited to launch the public preview of AI Performance in BWT! See when your content appears in Copilot, Bing AI answers, and select partner experiences - including when pages are cited, top referenced URLs, and grounding queries. GEO meets SEO! blogs.bing.com/webmaster/Fe...

We recently added support for adding specific URLs to our CrUX trends dashboard – not just entire domains! www.debugbear.com/docs/crux-tr...

Was a few months ago that i did this, and nothing has changed. Adding go faster stripes on your car is not going to make any difference to your monthly grocery shopping trip - make sure your car works well and can get your there and back.

In Google Search Console's "Crawl stats" report, whenever I see a high percentage of product URLs that shouldn't be crawled, I first head to Merchant Center. More often than not, these URLs are used in the Merchant Center feed, showing Google must rely on it a lot for product URL discovery.

2 MB of HTML is a lot of HTML, so probably don't stress: tamethebots.com/blog-n-bits/...

At the risk of overselling how much of a real world issue this is (it really isn't for 99.99% of sites I'd imagine), I added functionality to tamethebots.com/tools/fetch-... to cap text based files to 2 MB to simulate this.

Chunked search across the developer documentation (including Search Central) - including an MCP server. Now in public preview.

"here" being the PG rated version. console.log("why won't you ***ing work")

So it seems the max HTML size for the initial HTML is 2 MB, not 15 MB, which sounds like a huge reduction, but in the real world 2 MB of raw HTML is a BIG, like REALLY big file. 1/2

From Chrome 145 (on general release next week!), DevTools we will start to show so called "soft" navigations and "Soft LCP" in the Performance Panel traces. These are for SPAs which don't do a full page load, but instead "fake it" by updating the current page and pushing a new history entry. 1/5 🧵

I just merged the code change for this. We'll now have new Device Memory API limits from Chrome 146 and other Chromium-based browsers: - Android: 2, 4, 8 - Others: 2, 4, 8, 16, 32 Replacing the old values of 0.25, 0.5, 1, 2, 4, 8 which have grown outdated. Next up, updating MDN documentation...

Today I learnt I found Io down the back of my fridge.

Reminder this is rolling out in Chrome 145 so if you are using the attribution data for any CLS tools to show the squares moving, then you might wanna check they still work with this change in Chrome 145. Note CLS scores are NOT changing with this change. It's only the attribution rectangles.

The 2025 Web Almanac was published this week and I've put together some insights from the chapters I contributed to. Huge thanks to the community who made it possible. It was a real pleasure working with you all. montserrat-cano.com/insights-fro...

The new Web Almanac is out. 🎉 If you don't know the Web Almanac, it's pretty much a summary and analysis of the state of the web based on real data from the HTTP Archive. As a yearly tradition, I'll go over it and highlight/comment on the things that stand out. Let's go! 🧵

Whoop whoop! Almanac is out! Really enjoyed being an analyst this year for the page weight chapter, & am hugely impressed by what @not-a-robot.com & @barkseo.bsky.social wove with that data. 👏 to @montsecano.bsky.social for editorial chops & of @tunetheweb.com, who is a whole new plane of helpful!

I’m making my paid course free. A few years ago, I created a niche course on building custom reports in GA4. I made it because the default GA4 reports aren’t that useful when you’re trying to get the exact data you need. So I learned the process and turned it into a course.

Wait, tuna chunking content isn't a good idea? :) Good episode of SOTR with John and Danny From Danny about 'chunking' your content: "So, we DON'T want you to do that. I was talking to some (Search) engineers about that. We don't want you to do that. We really don't."
