Last January, Google made it possible for users to see clothes, shoes, and other products all at once along with the specific brands and retailers. This made it possible for retailers to display the products and brands they carried directly in the user’s search results. All webmasters and SEOs had to do to have their products visible in the search results is by using schema markups or by directly submitting the products in Google Merchant Center.
However, Google also stated that they may include products/content related to retail that were crawled, even though it wasn’t marked up using schema or submitted to Google Merchant Center. This meant that we didn’t have that great of a control over which products and corresponding information are displayed in the search results – until now.
