Hyperlink update help

I need to change a hyperlink on a product page but cannot find where to do this. Here is a link to a product for my site. The problem is that when you click “Shop” under the product name, it links to a google search and not the shop page. I can’t figure out where to change this at as I am new to wordpress and PHP.
