First Google added “Google Checkout” logos to the AdWords results for participating merchants. Then they offered “product images” for retailers. Today I noticed the latest non-text test on AdWords search – mini logos (or, maybe these are favicons, I don’t know). See screenshot below – the keyword I typed in was “project manager degree.”
I’ve said this before – why not just go all out and try banners on Google search? Sure the negative press would initially be bad, but if it monetizes better it can’t possibly be evil, right?
