This is May from Shopify.
It looks like the ‘Search’ link on the bottom of your page is part of a menu item. You can remove this by editing your navigation menu. Here is how you can achieve this!
From your admin, go to ‘Online Store > Navigation’. Then, select ‘Footer Menu’.
2. Under ‘Menu Items’, click on the trash can to remove ‘Search’.
3. Click ‘Save’.
You can also customize your theme to modify your footer. If you click on ‘Online Store > Customize > Footer’, you can add a different menu or add a newsletter signup from this page.
