Forrester Research analyst Jeremiah Owyang thinks so.
I'm not convinced though - his hypothesis only holds water when people use Google to look for a company. So if 50-60% of the web traffic to your company's site comes via Google (as ours does) then it's a fair point - but only for that proportion. You can pretty much guarantee that the first page of search results for your brand name on Google will shape someone's perception about your company - the job of your web site is then to either reinforce or attempt to change that perception.
I have been banging on for some time now about the need for companies to invest as much attention - and budget - on the 99.999999% of the Internet that they don't control as the remaining 0.000001% that they do (i.e. their website).
The examples in Jeremiah's post simply serve to reinforce that view.
