Incorrect Variant Price Displayed on Google Shopping/Merchant Centre

Shopify Discussion

Topic summary

A Shopify merchant is experiencing an issue where Google Shopping ads display the lowest variant price ($12.95) for all product sizes, regardless of the actual variant selected. This creates customer confusion and complaints about misleading pricing.

The Problem:

  • All variants of a castor oil product show as $12.95 in Google Shopping
  • Variant-specific URLs in Google Merchant Center aren’t displaying correct prices
  • Affects multiple product sizes (200mL, 500mL)

Proposed Solution:
One respondent suggests updating structured data and OpenGraph metadata to ensure variant-specific prices display correctly. They provide code snippets for:

  • Structured data implementation that targets the selected variant
  • OpenGraph metadata adjustments

The solution involves modifying Shopify theme code to properly pass variant-specific pricing information to Google’s systems. The discussion remains technical and implementation-focused, with no confirmation yet whether the suggested fix resolved the issue.

I have a few items on google merchant center which seem to be displaying an incorrect price on google shopping ads.

It seems to apply the price of the first/lowest variant to all variant sizes.

Example product from my website:

https://aboutmeorganics.com.au/products/natures-shield-organic-castor-oil?variant=44829911056548

All variants on here are displaying as $12.95 on the shopping ad leading to some customers being annoyed and saying it’s misleading.

The URL’s in merchant centre for the 200mL and 500mL are as follows:

200mL - https://aboutmeorganics.com.au/products/natures-shield-organic-castor-oil?variant=44829910859940&currency=AUD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic

500mL - https://aboutmeorganics.com.au/products/natures-shield-organic-castor-oil?variant=44829911056548&currency=AUD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic

In this case, you need to updated your structured data and opengraph data. To ensure when a variant link is used, the specific price only shows.

For example this code will do the trick for structured data:


{%- assign fa_product_id_alpha2_code = 'US' -%}

{%- assign fa_product_id = 'default' -%}

{%- assign fa_return_days = 28 -%}

{% if cart.currency.iso_code == 'USD' %}
    {%- assign fa_shipping_currency = "USD" -%}
    {% if fa_product_price >= "75" %}
        {%- assign fa_shipping_price = 0.00 -%}
    {%- else -%}
        {%- assign fa_shipping_price = 4.50 -%}
    {%- endif -%}
{%- endif -%}
{%- assign fa_shipping_handling_time_min = 0 -%}
{%- assign fa_shipping_handling_time_max = 1 -%}
{%- assign fa_shipping_shipping_time_min = 2 -%}
{%- assign fa_shipping_shipping_time_max = 5 -%}

{%- assign fa_returns = 'true' -%}
{%- assign fa_shipping = 'true' -%}

{%- if template contains 'product' -%}

{%- assign fa_current_variant = product.selected_or_first_available_variant -%}

{%- if fa_product_id == 'default' -%}
{%- capture fa_product_id_value -%}shopify_{{ fa_product_id_alpha2_code }}_{{ product.id }}_{{ fa_current_variant.id }}{%- endcapture -%}
{%- elsif fa_product_id == 'product_id' -%}
{%- capture fa_product_id_value -%}{{ fa_current_variant.id }}{%- endcapture -%}
{%- elsif fa_product_id == 'parent_id' -%}
{%- capture fa_product_id_value -%}{{product.id }}{%- endcapture -%}
{%- elsif fa_product_id == 'sku' -%}
{%- capture fa_product_id_value -%}{{ fa_current_variant.sku | escape }}{%- endcapture -%}
{%- endif -%}

{%- if cart.currency.iso_code == 'GBP' or cart.currency.iso_code == 'USD' or cart.currency.iso_code == 'JPY' or cart.currency.iso_code == 'AUD' or cart.currency.iso_code == 'AED' or cart.currency.iso_code == 'CAD' or cart.currency.iso_code == 'BWP' or cart.currency.iso_code == 'BND' or cart.currency.iso_code == 'DOP' or cart.currency.iso_code == 'GTQ' or cart.currency.iso_code == 'HKD' or cart.currency.iso_code == 'INR' or cart.currency.iso_code == 'ILS' or cart.currency.iso_code == 'YEN' or cart.currency.iso_code == 'KES' or cart.currency.iso_code == 'KOR' or cart.currency.iso_code == 'LBP' or cart.currency.iso_code == 'MYR' or cart.currency.iso_code == 'MXN' or cart.currency.iso_code == 'NPR' or cart.currency.iso_code == 'NZD' or cart.currency.iso_code == 'NIO' or cart.currency.iso_code == 'NGN' or cart.currency.iso_code == 'PKR' or cart.currency.iso_code == 'CNY' or cart.currency.iso_code == 'PHP' or cart.currency.iso_code == 'SGD' or cart.currency.iso_code == 'LKR' or cart.currency.iso_code == 'CHF' or cart.currency.iso_code == 'TWD' or cart.currency.iso_code == 'TSH' or cart.currency.iso_code == 'THB' or cart.currency.iso_code == 'UGX' or cart.currency.iso_code == 'KWD' or cart.currency.iso_code == 'CLP' or cart.currency.iso_code == 'BHD' -%}
{%- assign fa_product_price = fa_current_variant.price | money_without_currency | remove:',' -%}
{%- else -%}
{%- assign fa_product_price = fa_current_variant.price | money_without_currency | remove:'.' | replace: ',', '.' -%}
{%- endif -%}

{%- endif -%}

You still need to change the metafields for opengraph, simply open the snippet code, and edit it, so the variants are shown.

{% if template.name == 'product' %}
	{%- assign fa_current_variant = product.selected_or_first_available_variant -%}
	{%- if cart.currency.iso_code == 'GBP' or cart.currency.iso_code == 'USD' or cart.currency.iso_code == 'JPY' or cart.currency.iso_code == 'AUD' or cart.currency.iso_code == 'AED' or cart.currency.iso_code == 'CAD' or cart.currency.iso_code == 'BWP' or cart.currency.iso_code == 'BND' or cart.currency.iso_code == 'DOP' or cart.currency.iso_code == 'GTQ' or cart.currency.iso_code == 'HKD' or cart.currency.iso_code == 'INR' or cart.currency.iso_code == 'ILS' or cart.currency.iso_code == 'YEN' or cart.currency.iso_code == 'KES' or cart.currency.iso_code == 'KOR' or cart.currency.iso_code == 'LBP' or cart.currency.iso_code == 'MYR' or cart.currency.iso_code == 'MXN' or cart.currency.iso_code == 'NPR' or cart.currency.iso_code == 'NZD' or cart.currency.iso_code == 'NIO' or cart.currency.iso_code == 'NGN' or cart.currency.iso_code == 'PKR' or cart.currency.iso_code == 'CNY' or cart.currency.iso_code == 'PHP' or cart.currency.iso_code == 'SGD' or cart.currency.iso_code == 'LKR' or cart.currency.iso_code == 'CHF' or cart.currency.iso_code == 'TWD' or cart.currency.iso_code == 'TSH' or cart.currency.iso_code == 'THB' or cart.currency.iso_code == 'UGX' or cart.currency.iso_code == 'KWD' or cart.currency.iso_code == 'CLP' or cart.currency.iso_code == 'BHD' -%}
    {%- assign fa_product_price = fa_current_variant.price | money_without_currency | remove:',' -%}
    {%- else -%}
    {%- assign fa_product_price = fa_current_variant.price | money_without_currency | remove:'.' | replace: ',', '.' -%}
    {%- endif -%}
    
    
    
{% endif %}
