Once known as Google Product Search and way before that known also as Froogle (which in terms of puns isn’t the most fitting, surely nobody involved wants you to be economical with your cash), now simply Google Shopping, this is a service that lets consumers search for products and compare prices through Google Search.
Previously I had assumed that consumer products appeared on SERPS through an ecommerce site’s own specific markup or through the relative strength of the Google algorithm.
This is no longer necessarily true. Since Google Product Search transformed into Google Shopping, ecommerce sites now have to pay to have their products appear in these listings.
Google Shopping is not a place for organic listings, it’s a place for search marketers and advertisers to exploit. In some respects this is great, especially if you’re a small business with a significant enough budget to go up against the bigger brands. There’s theoretically much less competition now.
