Traditionally, Google Adwords would display 3 text ads at the top along with an additional 8 text ads running down on the right hand side. This no longer the case.
Google have recently formatted their search results to show 4 text ads at the top and 3 text ads at the bottom of Google results and product image ads to appear on the right hand side. This is a fantastic opportunity for ecommerce websites to showcase their products, including an image, a small description and the price before a user visits your website. How does Google know which product to display when a user searches for something? Well, the ads are shown in relevance to keywords in the user’s search query that match your product.
