No-code BigCommerce Customization Options

BigCommerce Templates

When coming to creating your personalized BigCommerce theme with user-friendly customization features, you can experience two ways to do it:

  • Using the built-in editor: Offering a variety of professionally designed themes that you will customize with logos, colors, and fonts.
  • Custom themes: For more advanced customization with basic HTML and CSS knowledge, BigCommerce offers the ability to edit theme files. 

Using the built-in editor (BigCommerce Page Builder)

Step 1: Log into a Dashboard and go to a Page Builder, click on the “Storefront” button

  • Once you are at your BigCommerce Dashboard, click on the "Storefront" button. Here, you can edit your logo and homepage slides, modify scripts, and more. 
Using the built-in editor 1
  • Next, go to the Page Builder by clicking the "Customize" button. This default drag-and-drop visual editor makes it easy to create and customize your website template without coding.

Using the built-in editor 3
  • Alternatively, directly open products, categories, and brands using the Action icon and selecting "View in Page Builder."
Using the built-in editor 4
  • When viewing your storefront while logged into the control panel, you'll see an admin bar at the top of the screen. This bar allows you to design the current page using Page Builder. Simply click on it, and start customizing your page.

Step 2: Adding or Editing Widgets

In the Page Builder sidebar, you'll find all the widgets available. These widgets include images, carousels, videos, products, text, and custom HTML.

Using the built-in editor 6
  • For tablet and mobile views, click the icon again to switch between vertical and horizontal orientation. For a full-screen preview of your changes, click "Preview" to collapse the left navigation.
Using the built-in editor 7

While in Preview mode, you can navigate your site just as you would on the storefront. This helps visualize how your style changes will appear on specific pages.

  • After adding the carousel widget, you can edit the background image by clicking the brush icon next to "Background." 
Using the built-in editor 8
  • Underneath, you can edit the Box, Title, Description, and Button. You can also hide any of these elements by clicking the "eye" icon next to them.
Using the built-in editor 9
  •  Additionally, you can change the color of the box, customize the title and description's font, weight, and size, and adjust the color and shape of the CTA (call-to-action) button.

Edit theme file 

BigCommerce allows users familiar with HTML and CSS to directly edit theme files for further customization. However, for JavaScript modifications, installing the Stencil CLI theme engine is necessary.

  • Before making any changes, create a backup of your theme. Click on "Advanced" > "Make a Copy" to create a backup that will appear as an inactive theme under "My Themes."
Using the built-in editor 10
  • Once the backup is ready, choose the copied theme; on the “Theme option,” click "Edit Theme Files" to customize your theme.
Using the built-in editor 11
  • After your backup is ready, it will appear under "My Themes" as an inactive theme. Click on "Edit Theme Files." If your browser blocks the pop-up window, you will need to allow it. A new window will open, displaying the structure of your homepage by default (home.html).
Using the built-in editor 12

The left sidebar organizes files and folders, with JSON and JS files appearing greyed out, signifying they can only be modified using the Stencil CLI theme engine. 

  • Within the "assets" folder, you'll discover essential resources for customization, including fonts, icons, images, JS files, and CSS. Notably, the "theme.scss" file within "assets > scss > theme.scss" acts as the core CSS file, enabling you to adjust elements like size and color beyond the capabilities of the Page Builder.
  • Exploring the "templates" folder reveals the underlying structure of your pages and components. For instance, you can alter the layout of the product page, modifying elements such as SKU and Availability. 

BigCommerce Customize mobile version 

Step 1: Enabling the Mobile Theme

  • Head to Storefront › Mobile Theme Settings. Check the "Yes, enable the mobile theme" box to activate it.

Step 3: Making Changes

To customize your BigCommerce mobile theme, edit the HTML and CSS files using a plain text editor.

Step 4: Uploading Your Changes

  • To upload the mobile template file, we need to connect to WebDAV.
  • In your control panel, navigate to “Server Settings” > “File Access (WebDAV).” Copy the WebDAV Username and Password.

Here are the steps to access WebDAV:

  1. In your control panel, navigate to Server Settings › File Access (WebDAV) and click Download. This will download a Cyberduck connection file to your computer.
  2. Open the downloaded file. It will automatically establish a connection to your store’s server in your WebDAV client.
  3. Upload any customized files to the mobile_template directory. Ensure you follow the same template structure as the one in the file you originally downloaded in the “Downloading the Mobile Template” section above.

Note: Files like "default.html" should be uploaded outside of the folders in WebDAV, mirroring their structure in the downloaded template.

Pre-Integrated Apps

BigCommerce offers a wide array of pre-integrated apps that effortlessly integrate with your store, covering everything from marketing and sales to customer service and analytics. With seamless integration, adding these apps is as simple as a few clicks, eliminating complex setup or coding.

Customizing data analytics in BigCommerce allows you to gain insights into your store's performance, customer behavior, and marketing effectiveness.

These steps will show you how to connect Google Analytics with your store and unlock enhanced features and insights.

Step 1: Review The Requirements

Requirements for Adding Google Analytics 4 to Your BigCommerce Store:

  • User Permissions: Ensure you have the "Manage Web Analytics" permission enabled on your account.
  • Google Analytics Account: Set up a Google Analytics account if you don't have one. Consider creating separate accounts for each storefront if you have multiple.
  • GA4 Measurement ID: Obtain your GA4 Measurement ID, as it's crucial for integration with BigCommerce.
  • API Secret (Optional): Create an API Secret in Google Analytics to track refunds for deeper insights.
  • Stencil Theme: Your storefront must be using a Stencil theme.
  • BigCommerce Storefront: The integration only works with BigCommerce storefronts, not headless storefronts.
  • Optimized One-Page Checkout: Your store must use Optimized One-Page Checkout. Legacy and Custom Checkouts are not supported.

Step 2: Add Google Analytics 4 Property

  • Select Web as the data stream type.
  • Keep the enhanced measurement enabled (Recommended)
  • You can skip Set up data collection for websites; the integration will add the tag automatically.

If your BigCommerce store already uses Universal Analytics, refer to Google's official documentation on how to add a Google Analytics 4 property to your website. It's crucial to enable the option "Enable data collection using your existing tags" to ensure uninterrupted data collection during the transition.

Step 3: Obtain GA4 Measurement ID

Go to “Admin” > “Data Streams” and click on your storefront’s stream. You need to ensure you’ve selected the right account.
