Good website structure is essential for 2 causes:

  1. It helps engines like google crawl and perceive the relationships between your pages
  2. It helps customers navigate your website

Let’s think about three key features of website structure. And the right way to analyze them with the technical search engine optimisation audit device.

Web site Hierarchy

Web site hierarchy (or website construction) is how your pages are organized into subfolders.

To grasp website’s hierarchy, navigate to the “Crawled Pages” tab in Web site Audit.

You’ll see your web site’s subdomains and subfolders. Evaluate them to verify the hierarchy is organized and logical.

Purpose for a flat website structure, which seems to be like this:

a flat site architecture where users can access pages from your homepage within three clicks

Ideally, it ought to solely take a person three clicks to seek out the web page they need out of your homepage.

When it takes greater than three clicks to navigate your website, its hierarchy is just too deep. Search engines like google think about pages deep within the hierarchy to be much less essential or related to a search question.

To make sure all of your pages fulfill this requirement, keep inside the “Crawled Pages” tab and swap again to the “Pages” view.
