Only 20% of Google queries are unique
Last Friday Google almost carelessly mentioned in a blog post that "20% of Google search queries are ones we haven't seen in the past 90 days". This is an interesting statistic and can be interpreted in a number of ways.
Keeping in mind that Google handles billions of search queries every day, this 20% figure seems to indicate that the long tail of search perhaps isn't so long after all. Effectively it means that 8 out of 10 searches are repeated at least once over a 3 month period. Or, in web analytics terms, of all searches by volume only the bottom fifth has 1 hit.
