Google is aiming to help advertisers figure out how their online campaigns work across their networks; to do this, Google purchased the Austin online ad attribution firm Adometry. Though terms of the deal have yet to be announced, Adometry recently raised $8 million in funding, so the deal will likely be around that much or more. Many individual companies monitor their own advertising networks and offer their own attributions, as well as exchanges, but the logic behind this particular purchase is that Google wants to capture a larger share of online ads overall, and wants to convince brands that its ad strategy is on point. Expect Google ads to only increase in power from their current position.
