What is site architecture?
Site architecture is the way a website's pages are organized and connected through navigation and links. A clear structure helps visitors find content and helps search engines crawl the site and understand how pages relate.

Why site architecture matters
Search engines discover pages by following links, so a well-planned structure makes sure important pages are easy to reach. It also shows which pages are main topics and which support them.
Visitors benefit too. When they can find things quickly, they are more likely to stay and act.
What good architecture looks like
Group related pages under clear categories, and keep key pages within a few clicks of the homepage. Use descriptive, consistent URLs and navigation labels.
Support the structure with internal links and breadcrumbs, and avoid orphan pages that nothing links to.
How to plan it
Start from your keyword research and group topics into logical sections. Map each page to a single purpose, then check the result with a site crawl.
Common questions
How many clicks deep should a page be?
There's no fixed limit, but important pages should be easy to reach, ideally within a few clicks of the homepage. Deeper pages tend to be crawled and discovered less often.
What is a flat site structure?
It's a structure where most pages are only a few clicks from the homepage. It keeps content easy to find, though large sites still need categories to stay organized.
Do URLs need to reflect the site structure?
It helps but isn't required. Logical, readable URLs make the structure clearer to people and search engines.
How are breadcrumbs related to site architecture?
Breadcrumbs show a page's place in the hierarchy and add internal links to its parent sections. They can also appear in search results.
