Flat site architecture is a website structure approach that minimizes the number of clicks required to reach any page from the homepage, keeping most content within just two or three levels deep, as opposed to a deeply nested, hierarchical structure.
This approach helps ensure search engines can efficiently crawl and discover all of a site’s content, and generally distributes internal link equity more evenly across pages compared to a very deep, narrow hierarchy.
Flat architecture works particularly well for small to medium-sized websites, while very large sites, such as major e-commerce catalogs, often need a more structured hierarchy to remain organized and navigable.
