You already have customers buying from you. The question is whether you’re suggesting the one more thing they’d actually want, and whether you’re doing it well.
Artificial intelligence (AI) product recommendations at the product page, cart, and checkout are one of the simplest changes a small online store can make. You don’t need a data team. You need the right setting turned on, or a plugin that costs less than a lunch out.
Why This Works
The customer is already buying. A good suggestion, like the charger for the phone case or the refill for the starter kit, saves them a second trip. That’s service, not pressure.
Be careful with anyone promising a specific revenue jump. Results depend on your catalog, your prices, and how relevant the suggestions are. Test it and measure your own average order value (AOV) before and after.
Start Free
- Shopify: The free Shopify Search & Discovery app lets you customize the related and complementary product recommendations that many themes can show on product pages. Your theme needs a product recommendations section for them to appear.
- WooCommerce: Related products are built in and free. WooCommerce generates them automatically from shared categories and tags. Cross-sells, which show in the cart, are set by hand on each product.
If your products are tagged and categorized cleanly, these free options get you most of the way.
When You Want Smarter Suggestions: Shopify Plugins From $9.99
- Frequently Bought Together has a free Starter plan with up to 3 manual bundles. Paid plans add automatic recommendations: $14.99 a month for up to 50 orders, $19.99 for up to 500, and $39.99 for more than 500. Each paid plan has a 14-day free trial.
- ReConvert is free up to 50 orders or $50 in upsell revenue, then $9.99 a month up to 2,000 monthly orders. Its listing includes AI product recommendations and post-purchase upsells. Note the next tier jumps to $199 a month, so check where your order volume lands.
The Enterprise Option
Nosto doesn’t publish prices. Its pricing page offers a demo and custom pricing, which usually means it’s built for larger stores. Skip it unless you’ve clearly outgrown the plugins above.
When This Isn’t Worth It
If you sell a handful of products with nothing that naturally pairs, recommendations will just clutter your page. The same goes if your catalog is a mess. Fix your categories and tags first, because every one of these tools leans on them.
And if a plugin isn’t paying for itself after a month or two, cancel it. The free built-in options might be all you need.
The Takeaway
Turn on the free option today. On Shopify, install Search & Discovery and check that your theme shows recommendations. On WooCommerce, clean up your categories and add cross-sells to your top five sellers. Watch your AOV for a month. Then decide whether a $9.99 or $19.99 plugin is worth trying.
