The web you’re optimising for doesn’t exist anymore.

Most of what you publish will never make it to the surface - it’ll be scraped, compressed, and digested by machines that don’t see pages, only patterns.

I wrote about what this means for marketing.

Optimising for the surfaceless web
The web we built had surfaces. We could design them, decorate them, and fight for space upon them. That web is gone. There are no more surfaces - only systems.

A plumber drove past me with a Hotmail address on the side of his van.

For years, that would’ve been a red flag.

Now, in an age of AI-generated everything, it might be the most trustworthy thing I’ve seen all month.

The Hotmail effect
Once, a Hotmail address meant you didn’t know what you were doing. Now, it might mean you’re the only real thing left.

Find someone who doesn't know your business. Show them your homepage for exactly 5 seconds. Then ask:
"What does this company do?"
"Who do they do it for?"
If they hesitate, get it wrong, or give vague answers, you've found your problem. And it's costing you rankings, traffic, and customers.

With View Transitions now being Baseline Newly available, and the View Transition API consisting of various features, it can be confusing to know what is supported in which browser versions.

To help with that, I created this VT Feature Explorer (powered by View Transitions)

The web might change overnight. Are you ready?

On PodRocket, @jono.id makes the case for hedging our bets... not by chasing trends, but by doubling down on the fundamentals.

I’ve been investigating dead websites for years.

Same symptoms every time - bloated code, missing structure, too many dependencies and not enough care.

It’s not murder. It’s neglect.

And it’s everywhere.

The death of a website
The call came in after midnight. Another site down. Same pattern. Same rot. Somebody’s killing the web, and nobody’s talking.

I mentioned before that we’re switching Lighthouse Performance audits to the new and improved Insights. The same Insights that you can see in DevTools Performance panel traces.

That’s happening in Lighthouse 13 due to be released very soon. Maybe even this week!

For some reason when people say 'potential audience' or 'ideal customer' I'm fine, but as soon as they say 'persona' I think they are being too cowardly to admit they enjoy astrology.

1. I am being unfair.
but also
2. I have never seen personas applied in a way that didn't leave me more confused.

Your brand isn’t what people say about you. It’s what machines remember about you. And they don’t forget.

Every slow page, broken checkout, and bad datapoint leaves a scar. Scars spread, harden, and make you invisible.

That’s the machine immune system at work.

Marketing against the machine immune system
The future of marketing isn’t storytelling. It’s engineering trust into the systems that machines depend on.

🚨 New tool: Impolighthouse

Not just “how fast is my site?”, but “why is it slow, and what does that say about our org?”

A deliberately impolite wrapper on top of Lighthouse, that calls out your organizational cruft, blockers & bad decisions.

The browser is striking back.

Bloated stacks, fragile abstractions, bad defaults - it’s all catching up with us.

I’ll dig into all of this at Web Directions Dev Summit, Nov 19–20 (Sydney + online).

The Times appears to have interviewed an 'ex Buckingham Palace cleaner' who supposedly divulges royal stain removal secrets but doesn't seem to exist, is possibly AI, and probably placed by a PR agency to boost SEO for a tiling brand.

It's sad that we've normalised SEO conferences - that claim to educate on best practices - being openly sponsored by parasitical link vendors.

That’s not just tone deaf; it’s disengenuous, hypocritical, and sells our classrooms those least interested in education and evolution.

Most brand blogs are a waste of time.

Not because content doesn’t work - but because you’re doing it wrong.

Keyword sausage machines, “Admin” bylines, cautious filler…

It’s industrialised mediocrity, and it serves no purpose.

If you want your blog to sell, stop selling
Stop trying to make every page a conversion engine. Accept that ads and content are different things. Be useful, be generous, be memorable.
