The site, he explained, "mysteriously disappeared" from results returned for a search on "Brian Souter".
He has, therefore, pledged to launch a campaign to end what he called "search engine censorship".
"It's not Google's place to decide which sites we can see and those we can't," Sir Brian said in a statement.
Although Google declined to comment on the case specifically, the firm confirmed that site rankings were calculated from many different measures.
Indeed, Google explained that its search "algorithm relies on more than 200 signals to help people find the answers they're looking for", adding that last year alone it made "more than 500 improvements to our algorithm, while experimenting with thousands more".
It is widely reported that advice on how to improve the ranking have been passed to Sir Brian's office.
