How does libertarianism deal with "perjury" (and I believe by that you mean false advertising) ?
If, by perjury, they mean 'intentional deception', that's fraud, and damages can be collected.
Actual damage would need to be proven, however. Some joker who feels trivialized because his page didn't come up first in a search would have to prove he was actively damaged, not just "would have done better if they'd designed their search differently". Failure to get a benefit that one has not contracted for is not damage.
Of course, I speak only for myself - I'm unaware of any "official" libertarian policy in this.
