I really recommend using breadcrumbs on your website. Although Weebly doesn’t provide a way to add them, you can make them yourself. This can take some time on content heavy websites, but it greatly enhances the usability for your visitors (especially on content heavy websites).
This is how I do it:
Add a "Text" element on top of the page.
Now add the text:
Link to your homepage > Title of the page+ link it to that page > Subcategories
You can add a divider to close the breadcrumbs.
Once you made one example, you can copy it on other pages and make some changes.
