AI answer engines silently drop citations and wipe out publisher traffic, with no crawler-level visibility or way to charge for AI content use

Summary

Publishers are seeing ~90% of their traffic vanish overnight when AI Overviews stop citing their pages, while rankings and indexes remain intact. Google Search Console cannot confirm the cause: it reports search clicks and impressions, not which AI crawlers fetched the content, how often, or whether the content was ingested into AI answers. Site owners therefore cannot distinguish a verified search engine bot from an AI ingestion crawler, cannot prove their content powered the answer, and have no per-page mechanism to price or charge AI systems for that consumption. Existing analytics and bot-management tools only surface generic traffic metrics and blunt blocking rules, which risk SEO damage if legitimate search bots are caught. The result is an unsolved, high-anxiety blind spot: traffic and revenue collapse with no diagnostic trail and no monetization lever, exactly the gap a pay-per-crawl logging and HTTP 402 pricing layer is meant to close.
