Click Depth Optimization refers to the practice of reducing the number of clicks needed for a user to reach a specific page within a website. A low click depth makes navigation easier, improves user experience, and helps search engines crawl and index your site more efficiently.
To optimize click depth, it's important to review your site structure and make sure that the most important pages are accessible within a few clicks from the home page. SEO audit tools can help you analyze and improve your site structure.
For example, if your product pages are four or more clicks away from the home page, you could rearrange the navigation to make them more accessible, which not only improves usability but can also benefit your SEO.
