Outbidding ? yes
Not on that site..but outperforming for G "overall" yes..but not necessarily on that particular site..( in fact it performance on that particular site for that particular IBA cannot be calculated , because by definition each IBA shown on any site has no performance history on that site ..( each visitor sees a different IBA ..by definition ;)
only on the network..
IBAs outperform on "aggregate" over the content network,( thus G and advertisers who know how to use them like them ) they rarely "outperform", from an individual publisher point of view, on particular sites..
