Feedback pls. Interested in updating & affiliate marketing

Site URL: https://www.brigittebard.com

As a holistic dog trainer I also address diet, use supplements and am selective about food and treats. I would like to add a page that links to products and items I recommend for my clients that I use for training as well as for a better quality of life for the pups. Would love feedback on my website as well as guidance how to incorporate a product page into the site.

I see Footer text is not center, vertical.

Homepage Mobile. The page is long. You can add "back to top" button??

Thank you!
