Launched alongside Google's Shopping network, Google Merchant Center is a powerful tool that has become indispensable for any e-commerce business looking to advertise online.

 

In concrete terms, Google Merchant Center, also known as "GMC", is an interface where you can upload your product catalog. This allows you to keep all your product feeds and their information (name, description, price, attributes, etc.) in one centralized place.

You can even update product information directly online to always keep your catalog current, which represents a significant advantage in terms of time and organization.

Where Google Merchant Center really comes into its own is when launching a Google Shopping campaign. You can connect GMC to your Google Ads account, and once that is done, Google will be able to serve ads online that showcase your products and your business.

From a more technical standpoint, during a Shopping campaign, Google matches users' search queries with your product attributes. As with other Google networks, the algorithm aims to show the most relevant ads in response to user searches. With a well-optimized product feed, Google Merchant Center helps you gain visibility through better rankings, drives more qualified traffic to your site, and ultimately increases your chances of converting.

 

How to make the most of Google Merchant Center?

  1. Create your GMC account and verify your website

You will need to provide several pieces of information about your business. Note that you need a Google account to create a GMC.

 

  1. Link Merchant Center to your Google Ads account

Use your Google Ads customer ID to connect the two accounts. Also remember to link your Google Analytics account for better tracking.

 

  1. Create and upload your product feed

This takes the form of a file in .xml, .csv, .xls, or Google Sheets format. You will need to fill in a wide range of information about your products. Try to be as detailed as possible by completing optional fields so the algorithm has as much data to work with as possible. Then simply upload the feed. If you use a popular CMS (such as Shopify or PrestaShop), the feed import can be done automatically by connecting them!

 

  1. Create your Shopping campaign in Google Ads

Set up your Shopping campaign by selecting your GMC.

 

A few recommendations:

  • Use the official language of the country you want to target.
  • Inform customers of your returns and refunds policy to improve the user experience.
  • Update your product data as frequently as possible.
  • Include as many relevant keywords as possible in your product descriptions to cover a wide range of queries. As mentioned earlier, the algorithm relies on your product information to match it to users whose search would be relevant. 

 

In summary, Google Merchant Center is an essential tool for any e-commerce business looking to promote its products. Properly setting up and optimizing your product feeds can prove highly beneficial for your sales.
