Becuase humans are at work, the products are not limited to exact matches to the images, but similar or supporting products can be displayed. The product experts also earn commission on sales - a nice control method so that the best possible matches are featured on the images. You can apply to be a product expert on the Pixazza website.
Advertisers can apply to have their products included in Pixazza and can pay through either CPA, CPC or CPM models. For an advertiser this could be a valuable way to expand the reach of their products to thousands of outlets across the Web. Advertisers already in the mix include some big names such as Amazon, Zappos and BlueFly. But links are not limited to products. Just about anything has potential. For example, a photo of a beach might display a boat icon in the water. With a mouse-over a link to a travel package could be offered.
With Google backing, expect this technology to make in impact, both immediate and far-reaching.
