Google Analytics. Enhanced Ecommerce. Limit for product impressions - google-analytics

Question

Does anyone know something about limits for sending impressions data for enhanced ecommerce (Google Analytics)? I found strange behavior, that sending data more than about 8KB is restricted by google. I use data layer for sending ecommerce data. I have up to 100 products on page, also I use unicode to send product and category names. So, I have much data to send. And the worst, that GA don't track pageview. It just do not send collect request at all, if I try to push to much data. In documentation I didn't anything about it. Any ideas how to avoid such limit?

Answer 1

As for the first part of the question, the limit for a http request to the Google Analytics endpoint is 8192 bytes - this is stated in the documentation for the measurement protocol (which is the basis for Universal Analytics).
My only idea to avoid such a limit would be to send only a product id and custom attributes to make the http request smaller and try to use dimension widening to add product names etc. in the Analytics interface. However I have not tested this and am not quite sure if dimension widening can be applied to product data (UPDATE to add: At least with Enhanced Ecommerce enabled one can indeed upload product data and custom attributes for given SKUs/product names).

Answer 2

I am encountering this same problem. My solution thus far has been to page results.
As stated above, limiting the attributes being sent could help reduce the size.
Google's sample:
ga('ec:addImpression', { // Provide product details in an impressionFieldObject.
'id': 'P12345', // Product ID (string).
'name': 'Android Warhol T-Shirt', // Product name (string).
'category': 'Apparel/T-Shirts', // Product category (string).
'brand': 'Google', // Product brand (string).
'variant': 'Black', // Product variant (string).
'list': 'Search Results', // Product list (string).
'position': 1, // Product position (number).
'dimension1': 'Member' // Custom dimension (string).
});
This could potentially be reduced to:
ga('ec:addImpression', { // Provide product details in an impressionFieldObject.
'id': 'P12345', // Product ID (string).
'name': 'Android Warhol T-Shirt', // Product name (string).
'category': 'Apparel/T-Shirts', // Product category (string).
});
Thoughts, ideas?

I have the same problem.
if you only can send 10 products for impressions, add this code every 10 products:
ga('send','event','Ecommerce','Impressions','NamePage',{nonInteraction: true});
Example:
ga('ec:addImpression', { // Provide product details in an impressionFieldObject.
'id': 'P12345', // Product ID (string).
'name': 'Android Warhol T-Shirt', // Product name (string).
'category': 'Apparel/T-Shirts', // Product category (string).
'brand': 'Google', // Product brand (string).
'variant': 'Black', // Product variant (string).
'list': 'Search Results', // Product list (string).
'position': 1, // Product position (number).
'dimension1': 'Member' // Custom dimension (string).
});
....
....
ga('send','event','Ecommerce','Impressions','NamePage',{nonInteraction: true});
a('ec:addImpression', { // Provide product details in an impressionFieldObject.
'id': 'P12345', // Product ID (string).
'name': 'Android Warhol T-Shirt', // Product name (string).
'category': 'Apparel/T-Shirts', // Product category (string).
'brand': 'Google', // Product brand (string).
'variant': 'Black', // Product variant (string).
'list': 'Search Results', // Product list (string).
'position': 1, // Product position (number).
'dimension1': 'Member' // Custom dimension (string).
});
