The quick and easy approach to setting up custom Google Remarketing parameters in Shopify is to use the following tags (typically in your theme.liquid).
{{ product.id }}
{{ template }}
{{ product.price_min | money_without_currency }}
The issue that you’ll run into though, is that Google complains when the ecomm_totalvalue is wrapped in quotes.
So, we just remove the quotes, right?
Not exactly. Not every page on your site will be a product page, and hence will not have a price.
On the home page, for example, that would leave us with an invalid object:
ecomm_prodid: ‘ ‘,
ecomm_pagetype: ”,
ecomm_totalvalue: ,
One pretty quick trick that I use is to simply add a zero (0) before the value, as shown below.
<script type="text/javascript">
var google_tag_params = {
ecomm_prodid: '{{ product.id }}',
ecomm_pagetype: '{{ template }}',
ecomm_totalvalue: 0{{ product.price_min | money_without_currency }},
};
</script>Using this method, the worst that happens is you might get a price that looks like this:
021.99
Which is still a valid numeric value.
