Information architecture
How a site’s content is divided, named and connected. It is the only layer where a mistake compounds: every later decision about content, linking and templates inherits it.
Also written Site architecture or Search architecture. Atlas writes British English; the definition is the same.
01
Why it matters
The consequence, not the conceptEvery other layer stays local when it breaks. This one does not: a wrong division at the top is re-implemented by every template and internal link built afterwards, which is why it is cheap to fix early and expensive to fix at all.

Seven questionsA definition is only worth publishing if it is true of your site too. Atlas reads the site before the first conversation.
