WordPress
In a classic theme, go to Appearance → Menus, add a Custom Link with your shop's address and the label Shop, then save. In a block theme, open the Navigation block in the Site Editor and add a link.
Wix
In the editor's site menu, add a menu item that links to a web address, paste your shop's address, call it Shop and publish.
Squarespace
In Pages, add a Link to your main navigation, paste your shop's address and save.
Webflow
In the Designer, add a nav link to your Navbar, point it at your shop's address, then publish the site.
Jimdo
In your navigation settings, add an item that links to an external web address and paste your shop's link.
GoDaddy and Hostinger
Both site builders let you add a menu item that points to an external link. Paste your shop's address, call it Shop and publish.
Hand-coded sites
Add one line to your menu: <a href="…">Shop</a>. If the menu is repeated in several files, add it to each — or pass the line to whoever maintains the site.
e-monsite, Framer, Webnode and others
If your site builder can add a link to the menu, it works. If it can't, a button on your home page does the job just as well.
Built by an agency, or you can't edit it
Give us access and we'll add the link for you, or we send your web designer a one-line instruction. It's a small change on their side.
