To list your product on Google or to ensure that your product ads work seamlessly, Google directs online merchants and e-store owners to upload the product data in the form of a feed. The feed needs to be uploaded to the Google Merchant Center. 

What are Google shopping feed attributes? 

Google Shopping feed can, in its simplest form, be thought to be a list of products or a spreadsheet that contains your product name and details, making it easy for the Google crawler to access the details.  

Online merchants that have a handful of products can manually create the feed using Google Sheets. However, if there are tonnes of products, you would typically need an app or software program to auto-generate product feed in the most optimized manner.

Google shopping feed attributes are a list of characteristics that need to be optimized so that when a potential customer searches for a product, the crawler judges the products on these specific attributes to show your products to the customer. The search engine also uses attributes to help customers reach viable decisions. We will discuss each of these attributes in detail here.

Conclusion

Did you know that Google Shopping listings are far more impactful than listings on any other online site, including the big e-commerce marketplaces? Products that appear on the Google Shopping listings have the power to turn prospective buyers into confirmed buyers faster than any other online site, search engine, or e-commerce platform. 

Look at this piece of data:

  • At least 35% of Google searches for products converted into transactions. 
  • Only 20% of product searches on Amazon convert into transactions.
  • The conversion time (time between a product search and purchase) is usually 20 days on Google, while on Amazon, it is about 26 days. 

These facts prove the effectiveness of the feed and the need to optimize the Google Shopping feed attributes.
