Richard Ball has a great write up concerning Google’s Adsense for Domains program and potential abuses. He is concerned that certain keywords being bid on through Adwords are producing garbage traffic.
A whopping 72% of clicks for a single exact match keyword originated from the searchportal.information.com domain. Investigating this domain, it turns out to be owned by a company called Oversee.net that owns DomainSponsor, a parked domain operation.
What Richard seems to miss is why the traffic is garbage. It’s because Information.com is one of the largest arbitrage 1.0 operations around. The reason it doesn’t convert is because Information.com bids on long tail search words for cheap and then send the clicks to ads targeted at the high paying general search terms. Terms which may be related, but are not actually what the user was searching for.
