Definition
Information architecture (IA) is how a site is structured: its top-level navigation, URL hierarchy, content grouping, cross-linking, and naming. Good IA makes navigation obvious and reinforces topical authority; bad IA confuses users and fragments link equity.
Why it matters
IA sets a ceiling on SEO. Without a clear IA, internal links don't flow to the pages that should rank, users bounce, and crawlers deprioritize the site. Every rebuild starts with an IA pass before a pixel gets pushed.
How we think about it
We draft IA as a URL tree before writing any content. Services → tier pages → FAQs. Work → case studies. Resources → guides + glossary + tools. Every URL answers the question: what would a user expect to be here? Then content fills the tree.
