Your first site navigation consideration should be to avoid using navigation types that make it difficult for the search engines to crawl through your pages.
if your website is large, controlling the depth of your website through your site’s navigation structure alone isn’t entirely feasible. If you have 100 total pages, for example, you’d need more than 30 separate categories to make all of your pages accessible within three clicks using navigation structures alone, which would almost certainly bog down your site’s appearance and functionality.
So, while structuring your navigation paths correctly from the start can help to improve your website’s SEO performance, you can also decrease your site’s depth through the use of internal linking.
In the world of SEO, there are two types of backlinks:
External backlinks, which are links that point to your website from an entirely separate site, and
Internal backlinks, which consist of connections between individual pages within your website.
One final website structure element to consider is how your individual page URLs are built. As you might expect, there’s a potential SEO benefit to be had from integrating your company’s target keywords into this vital navigation area.
The specific steps you’ll need to take to set up an SEO-friendly URL structure depend on whether your site runs on HTML or a content management system (CMS) like WordPress, Joomla or Magento.
If you run an HTML-oriented website, your page URLs will be built according to the file names of every new HTML file you create and upload to your site.
