Google Ads

Google Ads (formerly Google AdWords) is the world's largest digital advertising platform, owned and operated by Alphabet Inc. Launched in October 2000 with a modest 350 advertisers, it has grown into a multi-hundred-billion-dollar revenue engine that funds the majority of Alphabet's global business. For brands and marketplaces operating in e-commerce, Google Ads is not just an advertising option — it is essential customer acquisition infrastructure.

The platform encompasses several distinct advertising products. Search campaigns display ads when users search for specific keywords on Google. Shopping campaigns display product images, prices, and retailer names directly in search results — one of the most commercially important ad formats for e-commerce brands. Display campaigns show visual ads across Google's Display Network. YouTube advertising reaches users across Google's video platform. Performance Max campaigns use machine learning to automatically optimise ad delivery across all Google channels simultaneously.

Why Google Ads matters for e-commerce

Google Search captures purchase intent at its most explicit: when a consumer types "buy running shoes size 10" or "best robot vacuum under 300 pounds", they are actively shopping. The ability to appear at the top of these results — with a product image, price, and retailer name — is enormously commercially valuable. For many product categories, a large proportion of product searches now begin on Google, making presence on Google Shopping effectively mandatory for brand visibility during the buying journey.

Google Merchant Centre

Google Merchant Centre is the product data hub that powers Shopping ads. Retailers and brands upload their product catalogue with titles, descriptions, images, prices, and availability, and Google uses this data to match products to relevant search queries. Free product listings on Google Shopping are also available alongside paid placements, making Merchant Centre important for both organic and paid visibility in e-commerce.
