A regex matched <pre> as <p> and made half my blog invisible
Half of one of my blog posts was invisible: dark text on a dark code block. The stored HTML was fine, so the bug was in my own content formatter, a regex that treated pre tags as paragraphs. Here's the one-character fix and the lesson that isn't "don't parse HTML with regex."

Favicon Size in 2026: Why Every Guide Gives You a Different Number
MDN says 16×16. Google says bigger than 48×48. Half the internet says multiples of 48, which Google's docs never actually say. They're not contradicting each other. They're answering different questions. Here's the reconciliation, and the three files you actually ship.

Content brief pipelines with Claude Code: the workflow that replaces €500 agency briefs
Agencies charge €300–500 for a single SEO content brief. Here's the Claude Code pipeline that produces a better one in 20 minutes for under a euro — with the prompts, the structured output, and the parts that still need a human.
I asked 5 AI models who the best AI SEO experts are. Here's what they said (and why it matters)

I Built a Council of AI Advisors Because the Old One Died Right When I Needed It
My coding agent runs a cheap model to save money. The trouble is the moments a cheap model quietly gets wrong. So I kept a smarter one on the bench — until the extension that was supposed to fetch it kept dying on long sessions. Here's what I built instead.

Meta Tags in Next.js: The App Router Metadata API End-to-End
In the App Router you don't hand-write meta tags — you export a metadata object or a generateMetadata function and Next.js handles the head. Here's how the whole system works, from static objects to dynamic OG images.
