What Is the Best Way to Optimize the "Load More" Button for Google

Hi Everyone,

This page uses F’in Sweet’s Attributes to create a load more button.

It’s an awesome button, but I’m not sure how to optimize it for SEO. SEMrush reports broken canonical links and broken internal links when I run website audits on it.

Is there anyone who can advise me on what to do? I appreciate your help!
