Troubleshoot recommendations

Most recommendation problems come down to three things: the block is not on the page, it has nothing to start from, or its settings leave no products. Here is how to find out which one it is.

I don't see Recommendations in bluebarry

Don't see Recommendations in the sidebar? Ask us and we'll switch them on. If Studio asks you to connect Shopify, click Connect Shopify or go to Integrations.

The block does not appear on my store

  1. In the Shopify theme editor, open App embeds and check that Bluebarry Core Script is on. See Fix the Shopify app embed not showing.
  2. Check that the bluebarry recs block is on the template you are looking at, and that its Block ID matches the ID on the block's Embed step. A duplicated block has a new ID.
  3. Check that the block still exists. A deleted block shows nothing.
  4. Open the block's preview and pick the same product under Source products. If the preview says No products to show, the block has nothing to recommend for that product. Read on.

A block with nothing to show hides itself, so an empty block and a missing block look the same on your store.

It is empty for some products

  • Complementary products need orders or pairings. A product that is rarely bought with anything has no order pairings yet. Import your order history (see Import orders) and add attribute pairings under Product pairings so every product in a category is covered.
  • Frequently viewed together fills up with products bought together while browsing data is thin. A new or quiet product can have neither.
  • Similar alternatives only compare products that share the chosen Product type attribute and sit inside Compare within. With Compare attributes set, both products need a value for at least one of them.
  • Eligible products conditions may leave too few products. The badge shows how many are left.
  • Hide sold-out products drops anything with a stock of 0 or less. If your stock attribute is wrong, pick the right one under Stock property.
  • A Hide rule under Personalizations may remove more than you meant, for example every product with a certain tag.

It is empty on the cart page or homepage

Away from a product page, a block recommends from what is in the cart. With an empty cart it has nothing to start from. On the cart page this is expected. For your homepage or a landing page, switch Product selection to Choose specific products.

It recommends the wrong products

  • Add a condition under Eligible products for anything that should never appear, such as samples or gift cards.
  • For alternatives, choose a Product type that describes what a product is, not its brand or a sale label.
  • Pin or boost the products you want first, for everyone or for a segment.
  • Ask Barry in the editor to review the pairings for you.

Prices are missing

Open Eligible products and check Price property. When it is set to None, cards show no price. Check the Currency under Design too.

The discount does not come off at checkout

  • In your Shopify admin, go to Discounts and check that bluebarry recommendation discount exists and is active. It is created the first time you save a block with an offer. If it is missing, save the block again and check once more. Still missing? Contact us.
  • A bundle discount needs the whole bundle in the cart, including the product the bundle starts with. Without it, only the product discount applies, if you set one.
  • The offer is attached to the cart when the shopper sees the block. Testing? Add the products from the block itself, not from another page.
  • Check the combination settings of your other active discounts in Shopify.

The numbers look low or empty

  • An impression only counts when the block was actually on screen, so a block far down the page gets fewer impressions than page views.
  • Orders need the checkout tracking of the bluebarry Shopify app, and they count for 7 days after a click.
  • Impact cards need traffic in both groups. Until then they say "Too little traffic to trust yet".

Still stuck?

Contact us with the block name and a link to a product page where it should appear. We'll take a look.
