There are several types of cross-sell sections that you can add to your product pages:
- People who viewed this product also viewed
- People who bought this product also bought
- You might also like
- May we suggest
- Complete the look
- More items in the collection
- Other products from the same brand
- Other products from the same designer
Obviously, don’t add all these sections : ) Choose what makes the most sense for your store.
Relevancy is what matters most here. Make sure that what you’re recommending is highly relevant for them, based on the product they’re looking at now, and if possible, based on their browsing and/or purchasing history.
