A website’s crawl depth is something that refers to the extent to which a search engine indexes the site’s content. A site that contains a high crawl depth gets a lot more indexed than a site with low crawl depth. It also refers to how many clicks it takes to reach a specific page on that site, which will begin from the domain’s homepage using the fewest ‘clicks’ as possible.
Easy to reach pages end up being visited by both search engines and users most often, so it’s important to make sure that every page on your site that contains value is easily accessible.
In the following Moz video, Eli shows how to analyze your site’s architecture via crawl depth, so you can adjust your internal linking structure to ease access to your most important pages and save on valuable crawl budget.
