About

Polynomial World publishes practical guides to web marketing and building with AI. It's run by a small team that works in digital marketing in Japan: search and social ads, analytics, SEO, and LINE marketing for the Japanese market. We increasingly use AI assistants to do that work, and we write up the setups and checklists we actually use.

Who it's for

Marketers, small-business owners, and solo builders who want to do things properly without hiring an agency or an engineer for every task. You don't need to code to follow most guides; where you do, we show every step.

What you'll find

• Web marketing: Google Ads, GA4, Search Console, UTM tracking, landing pages, and LINE Official Account.
• AI for marketers: connecting Meta Ads, GA4, Search Console, Google Ads, and WordPress to AI assistants with MCP, and prompting them well.
• Build and ship: vibe coding with care, deploying small sites, and free SSL.
• Career essays: Aaron Gayle's articles on moving from marketing and ad tech into AI and data. They are his own first-person writing and are credited to him.

How we write

• Official sources first. Product limits, settings, and policies are checked against the vendor's own documentation, and linked next to the claim.
• Dated. Ad platforms and AI tools change often. Guides say when they were checked, so you know when to look again.
• No invented numbers. We don't publish made-up statistics, case studies, or results. If something can't be confirmed, we leave it out or say so.
• Real setups. Several guides describe setups we run ourselves, with names and account details removed.

We use AI assistants to help research and draft, and we review every guide before it's published. Mistakes still happen; if you find one, tell us and we'll fix it.
