Been saying this for a while but the really exciting stuff on the web right now is all about how things we used to need JS for can now be done with pure CSS. There are a lot of opportunities to cut out client side bloat.

If you run a large-scale/complex site, this is important. Make sure you know where Googlebot could go crazy crawling. E.g. As Gary said, "once Googlebot discovers a set of URLs, it cannot make a decision about whether that URL space is good or not unless it crawled a large chunk of that URL space"

Stop turning your website into markdown. Meaning lives in structure, hierarchy and context. Flatten it and you don’t make it machine-friendly, you make it meaningless. Yes, AI might fetch your .md file. That’s convenience, not trust, and it won't scale. www.jonoalderson.com/conjecture/m...

The middle of the market is quietly dying. Breadth and “good enough” used to work because humans couldn’t see everything. Agents can. If you’re not the safest default or clearly the best, you’re just noise. www.jonoalderson.com/conjecture/t...

Fit width text in 1 line of CSS `text-grow: per-line scale;` nerdy.dev/css-text-grow (prototype in Canary 165+)

Don't forget all the GEO-Detox work that will be paid for next year. The cycle of ""SEO"" life.

I’ve been getting pitched by companies who create markdown/“LLM-friendly” variants of webpages. Curious to hear others’ perspectives on this (especially the longterm feasibility)…

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. www.jonoalderson.com/conjecture/o...

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. www.jonoalderson.com/conjecture/t...

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) web.dev/blog/same-do...

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. YT: buff.ly/xE4udjk Apple: buff.ly/azaJQ9g Spotify: buff.ly/YgpSFz4

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. www.jonoalderson.com/misc/the-dea...

Introducing the React Foundation

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. www.jonoalderson.com/conjecture/m...

🚨 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. www.jonoalderson.com/impolighthou...

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). 💸 Codes: jonodevsummit25 / jonodevsummit25streaming webdirections.org/dev-summit

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. pressgazette.co.uk/news/royal-c...

“The name is misleading. no-cache actually means “store this, but revalidate before reusing it.” Finally finished @jono.id guide to caching, took me about a week 🤣 www.jonoalderson.com/performance/...

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. www.jonoalderson.com/conjecture/s...

all the best windows software in history is called something like "joe's thing doer". it does the thing and nothing else and is available on a html website in plain text and takes up under a megabyte of space and uses default windows ui elements and will work until the heat death of the universe

Most devs don’t understand caching. And it shows. Slower sites. Fragile infra. Bigger bills. All because a few headers are misused or ignored. I wrote the complete guide to HTTP caching - every directive, pitfall & trick, from Cache-Control to Cloudflare quirks to the AI-mediated web.

95%?!? If it was any other organisational investment that failed to yield ROI on this scale, it would be toxic to even suggest implementing it in your business. Instead AI gets cheered on everywhere. We have collectively lost our fucking minds. www.axios.com/2025/08/21/a...

Most websites are loading fonts wrong. ❌ Google Fonts isn’t “free” (privacy + speed cost) ❌ Icon fonts were a mistake ❌ WOFF2 only - stop shipping TTF/WOFF ❌ Subset or bleed megabytes ❌ Fallbacks matter (and can be tuned!) www.jonoalderson.com/conjecture/y...

Two pro webperf tips! Are you using Annotations in your performance traces? developer.chrome.com/docs/devtool... And even when not needing to annotate, Gemini AI auto-annotations can quickly give you an idea what a bit of the flame chart is doing without you needing to dig in yourself. Try it out!

There’s no such thing as a backlink. A link only has value in the relationship between its source and destination. “Backlink,” “DoFollow,” “niche edit” - all made-up terms to flatten complexity into something easy to sell. www.jonoalderson.com/conjecture/n...

This is so sad. Not because AOL is shutting down it's dial-up internet service, but because it didn't shut down a decade ago. It's 2025. Everyone in America should have access to affordable broadband. Even rural towns.

“Our traffic’s down… but nothing’s changed on our website.” That’s exactly the problem. The internet moves. Competitors launch. Markets shift. Culture tilts. Attention flows elsewhere. Standing still isn’t safe. It’s a countdown clock. www.jonoalderson.com/conjecture/s...

Markets you’ll never sell to are shaping your success in the ones you care about. Search and LLMs learn from the whole messy, multilingual web. If you’re not influencing the right places, you’re leaving your visibility to chance. www.jonoalderson.com/conjecture/l...

You wrote a great piece, quoted some great minds in the SEO industry and then slapped GEO on it and ruined everything 🤡 dejan.ai/blog/journal...

The web isn’t URL-shaped anymore. Machines rip your pages apart, extract the claims, and decide what to trust. SEO isn’t about pages now – it’s about the graph of meaning around your brand. www.jonoalderson.com/conjecture/u...

Google Ads just made branded search a conversion metric. This might finally forces advertisers to value brand, give SEO proof it drives conversions, and shift measurement to where growth really starts. support.google.com/google-ads/a...

I just built a Microsoft Notepad AI agent that opens the Notepad app with a fresh new document when I click on the icon. AMA.

Why are we still using full-page overlays with loading bars in 2025? 🤯 It's basically proof that the developer know almost nothing about SEO and web performance. If you need a loading bar to fix something as a web developer, then something is clearly wrong. 🧵 1/2

I visited the world’s first factory. The original cotton mill that changed the world. It changed everything - labour, time, identity. Now it's a quiet museum. And I can’t stop thinking about AI. Because this all feels very familiar. www.jonoalderson.com/misc/what-th...
