Increasing your store’s average order value (AOV) does not always require complex tools or expensive apps. One of the most effective and beginner-friendly methods is cross-selling, showing customers additional items that complement the product they are currently viewing. Normally, many merchants assume they must rely on third-party apps or custom code to implement cross-selling, but that’s no longer the case. With Shopify Online Store 2.0, your theme already includes the ability to place product recommendations directly inside custom tabs, all through drag-and-drop editing.

Custom tabs help organize your product page layout, and adding cross-selling inside these tabs allows you to keep your design clean, structured, and user-focused. More importantly, this method requires no coding whatsoever, and you don’t need to install additional apps that may slow down your store. Everything is done natively using Shopify’s built-in theme editor.

In this guide, we’ll walk through how this works, why it’s effective, and how you can implement it step-by-step in your own store.

Why Use Custom Tabs for Cross-Selling?

Before diving into the setup, it’s helpful to understand why this technique works so well. Custom tabs are typically used to organize product descriptions, FAQs, and shipping policies, but they are also incredibly effective for displaying product recommendations. Here’s why.

1. Creates a Cleaner, More Organized Product Page

One of the biggest challenges in designing a Shopify product page is managing large amounts of information. When all details are shown at once, descriptions, reviews, materials, shipping info, the page can become long and overwhelming. Custom tabs solve this by neatly grouping the information. Because tabs reveal content only when clicked, you can place your cross-sell items inside one tab without cluttering the main product description.

This gives shoppers a more curated and less overwhelming experience. It feels clean, modern, and thoughtfully designed.

2. Encourages Higher Engagement and Intent

Shoppers click tabs because they want additional information about the product, which means they are already engaged and curious. When a customer intentionally opens a tab labeled “Complete the Look” or “You May Also Like,” they are in an exploratory mindset. This higher user intent significantly boosts the likelihood that they will interact with the recommended products.

By placing your cross-sell items in a tab rather than at the bottom of the page, you ensure they appear at a moment when the shopper is paying closer attention.

3. Provides a Mobile-Friendly Shopping Experience

Mobile traffic represents over half of most Shopify stores’ visitors. However, mobile screens have limited space, and long pages require excessive scrolling. Custom tabs reduce scrolling drastically by organizing all secondary details inside collapsible sections. This also prevents cross-sell blocks from pushing essential content down the page.

By placing your cross-selling items inside a tab, you ensure they display neatly and consistently across all device sizes, making the shopping experience smoother and more enjoyable.

4. Uses Your Theme’s Styles Automatically (No Apps Required)

Another major advantage is consistency. Since everything is added using your theme’s built-in blocks, cross-sell products automatically match:

  • your fonts
  • your button styles
  • your grid layout
  • your spacing and design system

This keeps everything visually cohesive, something many apps fail to do. And because no app scripts are loaded, your store remains faster, which improves both user experience and SEO.

What You Need Before Starting?

To implement this no-app, no-code method successfully, you only need:

  • A Shopify Online Store 2.0 theme (such as free themes like Dawn, Refresh, Taste, Sense, Origin, Impulse, Prestige, Warehouse, etc.)
  • A product template that includes Product Tabs, Collapsible Tabs, or Details Sections

Nearly all modern Shopify themes support this, so you should be able to follow the steps immediately.

How to Add Cross-Selling Inside Custom Tabs?

Now, let’s walk through the exact process. These steps use Shopify’s visual editor, so you simply drag, drop, and adjust blocks without touching any code at all.

Step 1: Open the Theme Editor

Start by opening your theme in editing mode.

  1. Go to your Shopify admin.
  2. Click Online Store > Themes > Customize.
  3. In the top navigation of the theme editor, choose Products > Default Product (or select a specific product template if you use different templates for different collections).

This loads your product page layout so you can modify its sections and blocks.

To make the editing process easier, Shopify also provides a live preview, so every change you make appears instantly.

Step 2: Locate Your Tab Section

Once inside the product page layout, look for the Template section where your product information is organized. Depending on your theme, this may be called:

  • Collapsible Tabs
  • Product Tabs
  • Collapsible Content
  • Details Tabs
  • Accordion Rows
  • FAQ-style Tabs

This is where you’ll add your cross-sell content. If your theme uses collapsible rows, you’ll simply insert content into one of these rows.

If you don’t see a tab section, some themes allow you to add one manually by clicking Add Section and selecting a collapsible tab component from the list.

Step 3: Create a Dedicated Tab for Cross-Selling

To keep your cross-sell items focused and easy to find, it’s best to create a new tab specifically for them.

  1. Inside the tab section, click Add Tab / Add Row / Add Block, depending on your theme’s structure.
  2. Give your tab a name that clearly conveys its purpose.

Effective names include:

  • Complete the Look
  • You May Also Like
  • Frequently Bought Together
  • Recommended Accessories
  • Perfect Pairings

A clear and enticing tab name increases click-through rate, which leads to more cross-sell interactions.

Step 4: Insert Shopify’s Built-In Product Recommendation Block

This is the most important step. Shopify themes include several native blocks for displaying recommended products.

Inside the tab you created:

  1. Click Add Block
  2. Choose a built-in block such as:
  • Recommended Products
  • Related Products
  • Complementary Products
  • Product Recommendations
  • Or any variation your theme offers

These blocks use Shopify’s algorithm to automatically pull relevant cross-sell items based on:

  • purchase patterns
  • product metadata
  • customer behavior
  • similar product categories

Because this is native Shopify functionality, everything loads quickly and fits your theme perfectly.

Step 5: Customize the Appearance of the Recommendations

Depending on your theme, you may see customization options such as:

  • number of products to display
  • number of columns (e.g., 2-column or 3-column grid)
  • image aspect ratio
  • card spacing
  • button visibility (e.g., show or hide “Add to Cart”)
  • text alignment

Take your time to adjust these elements so the tab layout feels balanced. Since tabs usually have limited space, it’s wise to use a compact grid of 2–4 products.

You can also add a short descriptive line above the recommendations, such as:

“These items pair perfectly with your selection and are frequently bought together.”

This makes the tab feel more polished and informative.

Step 6: Save Changes and Preview on All Devices

Before finishing, it’s important to test how your new cross-sell tab behaves across different devices.

  • On desktop, ensure the tab opens smoothly and the product grid looks clean.
  • On mobile, check that the tab collapses properly and that the recommendation layout is easy to scroll.
  • Switch between different products to ensure the recommendations remain relevant.

A quick preview allows you to catch small design issues early.

Best Practices for Maximizing Cross-Sell Conversions

Setting up cross-selling is only the first step. To maximize performance, consider the following proven tips.

1. Focus on Complementary Products, Not Random Ones

Relevance is the biggest driver of cross-sell conversions. Customers are far more likely to buy items that pair naturally with what they are viewing.

Examples:

  • Dresses → belts, handbags, earrings
  • Coffee machines → coffee beans, filters
  • Cameras → lenses, batteries, tripods
  • Gaming keyboards → mouse pads, wrist rests

Shopify’s recommendation engine usually handles this well, but you should still check manually to ensure suggestions make sense.

2. Keep the Number of Recommendations Small

A crowded tab reduces clarity and makes it harder for customers to choose. Three to six items is usually ideal.

A focused cross-sell layout feels curated and intentional, which builds trust and increases add-to-cart rates.

3. Use Compelling Tab Titles to Increase Clicks

Your tab title is the first thing customers see. A strong title encourages them to explore inside.

Compare:

  • “Accessories” (too generic)
  • “Perfect Add-Ons for This Product” (clear and persuasive)
  • Shop the Look (Recommended)” (specific and enticing)

These small wording improvements can significantly increase engagement.

4. Add a Short, Helpful Description Inside the Tab

A brief explanation makes your suggestions feel curated rather than automated.

For example:

“Customers often pair these items together for a better experience.” or

“These curated pieces help you complete the full look with ease.”

This adds context and builds buyer confidence.

5. Monitor Performance and Adjust Periodically

Since Shopify generates recommendations automatically, results may vary based on product data and customer behavior. Check regularly to ensure that:

  • irrelevant items are not being shown
  • best-selling accessories appear at the top
  • cross-sell items align with current product trends

Adjust expectations and tab titles as needed to keep engagement strong.

Conclusion

Setting up cross-selling inside custom tabs on Shopify is one of the simplest and most effective ways to increase average order value, without installing apps or touching code. Thanks to Shopify’s Online Store 2.0 editor, you can drag and drop native recommendation blocks directly inside your tab sections and instantly enhance your product page experience.

With just a few minutes of setup, your product pages become more helpful and more persuasive, encouraging customers to purchase complementary items and enjoy a better overall shopping experience.
