HELP: A Review on my Shopify store and its EXTREMELY low Conversion rate

ISSUE: Bounce rate has increased tremendously last couple months at 80%. Any ideas on how to improve the store?

Our Landing page is most often the dispenser we have – we have a pretty high bid on google ads that gets us customers there. Wondering if anyone could help me figure out why I'm losing customers lately.

Also, we added a bunch of products in December which have had no sales. Is it possible that our Shopify store is facing issues because we have too many products?

I use Shopify for my e-commerce business. Here is the Link: https://swach-canada.com
