Interesting to see the difference including soft navs in CrUX makes to LCP for social media, one place a SPA probably makes a lot of sense (looked at origins, all devices) Bsky 4.26s > 2.04s tamethebots.com/tools/cwv-hi... Facebook 3.33 > 1.24 tamethebots.com/tools/cwv-hi...

This is a great post from @gustav.ernberg.se and shows how you can use the BigQuery CrUX data to do analysis across sites to see the impact of the soft nav change announced this week. SQL included too to make it easier for you to do similar! gernberg.com/posts/2026/h...

🆕 The 202609 Chrome User Experience (CrUX) release is now live on BigQuery, and we also have an exciting addition to CrUX this month! Check out the announcement post for the full info: groups.google.com/a/chromium.o... Highlights below 👇 🧵 1/10

CrUX now has experimental data for soft navigations for LCP, INP & CLS, helping close the gap on those pesky SPAs! I have added to my CWV tool here: tamethebots.com/tools/cwv-hi... Read more about the release here: web.dev/blog/crux-ex...

The excellent @aleyda.bsky.social's SEOFOMO email just landed in my inbox, causing me to panic it's actually Sunday, not Sat, and I had lost a day, not out the question, just recovering from the traditional post-conference/ flying lurgy. Phew, still Saturday! Isn't it?

Search central deep dive day one is here (Sorry / thank you in advance for the 7 mins today that are my fault) #searchcentrallive #scldd2026

If you have an image-heavy website, Search Console now reports on "multimodal" queries like when you take a photo w/Lens. No, you don't see the photo :-), but you can see which of your pages showed up & how often. I think it's pretty cool, but I am biased :-). developers.google.com/search/blog/...

Just over a week until Search Central Live Deep Dive Europe 2026, where I am super excited to be giving a quick talk about robots.txt. I'm even more excited to learn from all the other great speakers! If you're there, do say hello 🙂 #searchcentrallive #scldd2026

This is a really cool addition! I have added these new metrics to my free CWV tool here: tamethebots.com/tools/cwv-hi...

In my audits, the question I hear most after a deploy is "why hasn't CrUX moved yet?" The window is always 28 days; daily, weekly and monthly are just cadences over the same data. And p75 resists change by design I explain it with two interactive demos joanleon.dev/en/crux-28-d... #WebPerf #CrUX

Your wallet was right there in your pocket in public ...

With Chrome 151, soft navigations entered the mainstream. If you haven't heard the term, a soft navigation is anything that: - is initiated by a user action - results in a visible URL change - results in a visible paint https://developer.chrome...

Updated tamethebots.com/tools/real-g... (and tamethebots.com/tools/real-l...) to set you paste in a list of IPs to test to see if they are real, it will spit out a CSV with the verdict. All done in browser.

Take a look at this great deep dive Tony did on WRS rendering time and other things! 🤘

It's very good. Chris has built a belter.

In chrome canary, you can now see metrics for soft navs in the Performance -> Live Metrics h/t @tunetheweb.com 🤘

Google's review markup docs updated to remind you not to be a shithead and mark up fake / paid for reviews. developers.google.com/search/docs/...

I've just release v6.0.0 of the web-vitals library. It includes support for measuring Web Vitals per soft navigation (like those used in SPAs) for supporting browsers (Chrome 151+) to give more accurate performance metrics for those sites. github.com/GoogleChrome...

I heard again the other day about the 5 second render timeout limit in Google's web rendering service. It's not real, but because of how the WRS works, it's understandable where that figure comes from. I did a test case and wrote it up here: tamethebots.com/blog-n-bits/...

🕵️ Single Page Apps can’t hide in the shadows anymore — now you can track Core Web Vitals for in-page navigations

Of course I had to recreate this with CSS/JS. codepen.io/defaced/pen/...

Odd, the self-packaging cat.

A properly made website works well for AI agents ... and search engines, and LLMs, and above all, for actual people. If you're trying to fix accessibility issues by making a separate "agent-friendly" version, you are just building technical debt. You'll have to redo it multiple times. Just fix it.

Reminder: tomorrow I'm hosting a 1 hour free webinar with UXPA on Enterprise UX. I’ll share why I actually enjoy working in Enterprise UX, what surprised me when I started, and how to grow in such environments. Here you go: uxpa.zoom.us/webinar/regi...

I wanted to learn more about User Agents and Bots for a project I am doing about data in LLMs. I built uatracer.com and I just wrote about it 👉 paul.kinlan.me/ua-tracer/

Brilliant find, have added Claude back into my Real LLM Bot IP? Tool, so you can see if it's really Claude come a crawlin` tamethebots.com/tools/real-l...

This is very cool. For those without the time to setup the demo example, I put a version here if you want to see it in action: testing.tamethebots.com/nativestream

Gemini, pray tell, what have you learned that humans do with microphones exactly?

If you're serving bots nicely formatted markdown but giving users div soup that forces them to download 15MB of JS that does nothing for them, you're treating humans as second class citizens. I wrote something to redress the balance a bit: chris-spann.co.uk/impersonatin...

I've added a convert to Markdown button to convert the rendered, or initial, html of the page you fetched to (you guessed it) Markdown, in case you like that kind of thing. tamethebots.com/tools/fetch-...

Do you think this linkedin request is from a genuine human? Because if so, I am totally jealous of their name.

A while back quite a few of you answered me on your annoyances with web payments. I've collated your responses and it looks like we're still doing forms like it's 1999 out there. More detail in the article, and let me know if there's more of your e-concerns with e-commerce rowan.fyi/posts/web-pa...

It's happening... We've asked Chromium API owners for permission to ship The Soft Navigation work to allow measuring of Core Web Vitals for SPAs!!
