Final Verdict
🧾 1. What Are Google Shopping Ads?
Google Shopping Ads are visual product ads that appear across Google’s network, especially in:
-
Google Search results (product carousel)
-
Google Shopping tab
-
Google Images
-
YouTube (occasionally)
-
Gmail and Display Network
These ads are fed from a Google Merchant Center product feed, and they show product image, price, merchant, ratings, and more — helping users compare products before clicking.
🛍 Ideal for driving traffic to your eCommerce site and capturing top-to-mid funnel shoppers.
🛒 2. What Are Amazon Ads?
Amazon Ads are paid placements within the Amazon ecosystem. There are three main types:
-
Sponsored Products: Appear in search results and product pages
-
Sponsored Brands: Show your logo and a selection of products
-
Sponsored Display: Retarget or display your ads across Amazon and third-party sites
Amazon Ads work within a closed marketplace — users see and purchase your products without ever leaving Amazon.
🛒 Ideal for bottom-of-funnel conversions where users already have buying intent.
