The TLD Owner

The .seo TLD owner.
Not a corporation.

kooky is an onchain TLD operator. He owns the .seo TLD outright — lifetime, no renewal, fully onchain. No VC board. No middleman.

kooky owns .seo the same way you'll own your SLD — permanently, on the blockchain. What you pay is a one-time acquisition. Not a subscription. Not a lease.

The vision

Why .seo is the SEO domain
professionals have been waiting for.

01

Your SEO domain signals who you are

agency.seo, rank.seo, audit.seo — before anyone reads a single word of your content, your domain is already making the case. In SEO, every signal counts.

02

Own your SEO domain — not rent it

Web2 domains are rented. You pay every year. The price can change. .seo SLDs are owned — minted onchain, non-custodial, transferable. from $5, once.

03

A namespace for a serious industry

SEO is a $100B+ industry. The professionals in it are technical, credible, forward-thinking. .seo is built specifically for them — not a generic extension for everyone.

04

First-mover on the best SEO domains

The namespace is open today. The agencies and professionals that claim their dot now own the best addresses in the SEO namespace — permanently. There's no second chance at agency.seo.
