It looks as though Google is in some hot water with The Australian Competition and Consumer Commission who allege that Google is using misleading and deceptive conduct with the way they display sponsor links.
The case concerns links listed as search results. The ACCC says consumers are being misled because there is no distinction between "organic" results - which Google sorts - and "sponsored links", or paid advertisements. The case, believed to be a world first, will be watched by other search engine sites.
