This guide teaches you how to add the favicon to your Shopify store in a few simple steps.

1. Create a 16x16 pixel or 32x32 pixel image that you want to use as the favicon. The image should be in .ico format. If you don't have a .ico file, you can use an online converter to convert your image to .ico format.

2. Go to your Shopify admin dashboard and click on the "Online Store" tab.

3. In the left-hand menu, click on the "Themes" option under the "Online Store" field.

4. Click on the "Actions" dropdown menu and select the "Edit code" option.

5. In the left-hand menu, click on the "Layout" folder and then click on the "theme.liquid" file.

6. Scroll down to the bottom of the file and find the "head" section.

7. Within the "head" section, paste the following code:

8. Replace "favicon.ico" with the name of your .ico file.

9. Click on the "Upload a file" button in the right-hand menu and select your favicon file.

10. Click the "Save" button to save your changes.

Your favicon should now be displayed in the browser tab of your Shopify store.

If you have followed these steps and the favicon is still not showing up, there may be an issue with the file itself. Make sure that the file is in the correct format and dimensions. If the problem persists, try using a different browser or device to see if the issue is specific to a particular browser or device. If the issue persists across multiple browsers and devices, there may be an issue with the way the favicon is being implemented on your store.
