Amazon continues to make news around its ambitions to invade the ad space. Last week, news broke that Amazon stopped buying (and offering its sellers) Google Search ads. These are the ads that appear alongside Google search results when Google users search for products. Amazon already has a very similar product, Headline Search Ads, that show up at the top when someone searches for a product on Amazon.com. You've seen it – it looks like the following ad. So it’s not surprising that, on conviction alone, Amazon wouldn't want to run similar ads on Google search.
