Information Architecture.

What is information architecture?

Information architecture (IA) is the way content on a website or app is organised, structured, labelled and connected so people can find what they need. It covers the sitemap, the navigation, the page hierarchy, the names of sections and how pages link to each other. Good IA is mostly invisible: visitors simply find the right page. Bad IA shows up as people searching, backtracking or leaving.

Why it matters

IA decides whether a buyer can get from "I have this problem" to "these people solve it" in a few clicks. It also shapes search performance, because search engines use your structure and internal links to understand which pages matter and what each one is about. A firm that offers six services but squeezes four of them into one long page is close to invisible for those four, both to visitors and to Google.

The parts that matter

• The sitemap The full list of pages and how they nest, from the homepage down to individual service and location pages.
• Navigation menus The menus and links that let people move around, designed around how buyers think.
• Plain labelling Names for sections and pages in the words customers use, instead of internal jargon.
• Internal linking Contextual links between related pages that guide visitors and spread search authority.
• URL structure Clean, predictable addresses that reflect the hierarchy.

What to do about it

Write out your current site structure as a simple indented list. Next to each page, note the search term or customer question it answers. Pages with no clear question are candidates for merging; questions with no page are gaps to fill. Check your menu labels against the language customers use on calls and in enquiry forms. If you are planning a rebuild, sign off this structure before any design work begins.
