Is Google Checkout a help?
Danny Sullivan recently had a post pointing out a change to the product OneBox. Not only are they promoting products, but there is a link for just those results available through Google Checkout. I guess that means if you want maximum exposure, you’ll need to start accepting Google’s payment option.
But, how do you go about doing that? If you’re manually submitting a product and you want it listed as a product on Base, just select that payment option. Very simple. If, like most people submitting feeds, you’d rather sell the products through your own site and manage the experience better and “accept Google Checkout on your site, you should put Checkout in the Payment_Notes field, not the payment_accepted field”. Brian Smith, once again, has all the details on the correct way to make that work.
While it doesn’t appear to make any difference in the rankings at this point, that extra link means extra visibility for those stores that do accept it. I’ve got it on my short list of things to add very soon, so I’ll share the results when I’ve learned something.
