> There are very clearly many queries with no advertising revenue, because there are many queries that show no ads.

Queries without ads do produce revenue. They are an essential part of the formula.

Think of people standing around in bars. We cant argue that just standing there doesn't produce revenue.

The flowers on the table in a restaurant produce revenue.

Free parking produces revenue.

If queries without adds didn't produce revenue they wouldn't exist. More often enough it doesn't even take an extra query, the adds will sit behind the links.
