I bet the sign itself serves as search engine optimization. If everybody starts searching for "foo" and clicks on my site in the result set then a reasonable search engine might bump my site up higher for searches for "foo."
That's an interesting hypothesis. It makes sense for the company both as optimization of their web pages for search engines and as making good impression on customers.
I've noticed more and more recently a trend of billboards and things that just say 'Search [name]' instead of putting their URL there.
