Facebook “Like” buttons are generated and styled by Facebook, so they are consistently easy to recognize - usually small blue buttons with the “f” icon on them, and sometimes with a Like “count” next to them, e.g.:
A Facebook “Like” button is not an element that is built into your theme, but if you have a Facebook fan page for your business, you can easily add one so that visitors can Like your brand on Facebook directly from your online shop.
STEP 1: On Facebook
Visit this page and follow the directions to configure your button and generate the required code: https://developers.facebook.com/docs/plugins/like-button
The process will go something like this:
When you press the “Get Code” button, it will give you two separate snippets of code that look something like this:
STEP 2: In Your theme
Determine where you want your button to appear, and if necessary, contact our Support Center to figure out which file you will need to work with to have that button show up in the right spot
Then paste the code snippet from part 2 of the code that was generated, into the determined spot in the relevant theme file. In my own example, I want this button to appear in my footer, so I added it to the theme.liquid file where the footer code is located, and it looked something like this:
After these two bits of code have been added to the appropriate theme files, you should now have a FB Like button added to your shop! In my own example, this now appears correctly in my footer area, where I wanted it, though of course in your own shop you can put it where you wish!
** Important! **
But remember that users can only “Like” (and therefore follow) your Facebook page, not your Shopify store, so if you want to use a FB Like button on your online shop, you need to have a Facebook page already set up for them to like!! ;)
