Choosing Navigation Depth with an Outsourced Website Design Team
A practical way to decide how many navigation levels an outsourced website design project should expose.

Navigation depth is not a contest to fit every page in the header. The right structure helps visitors predict where a page belongs and gives the site owner a manageable set of labels.
Begin with destinations
List the pages people need, their purpose, and the relationship between them. Group pages by visitor task rather than by internal department when those structures differ. The outsourced website design team can then test whether the labels make sense outside the sitemap document.
Decide what belongs in the first view
Keep the main navigation for destinations that support common journeys or explain the site's offer. Put supporting resources in a context where they are useful. Record required legal, account, and contact links separately so they are not accidentally removed during simplification.
Test labels in context
Ask a reviewer to find a named page from the header, a page link, and a narrow menu. Check long labels, focus order, expanded state, and the route after selection. A design that looks tidy can still make a visitor search for an important destination.
Approve the structure
The owner approves the information architecture. The design team documents the visible states, mobile behavior, and page-to-page links. Keep the navigation map with the source handoff so later page additions have an explicit place to go.
Measure depth by task, not clicks alone
A three-level menu can be easier than a one-level menu if labels match the visitor's language and the destination is predictable. Trace common tasks from the home page and note where a visitor must remember a category or use the back button. Keep utility links visible without allowing them to compete with the main service paths.
