Interesting idea from Indeed.com — pay-per-click, contextual job ads. This could be a logical evolution for top jobs — the industry-standard recruitment up sell. Another possible spin for newspapers, as an additional up sell, place recruitment liners as contextual ads in Google and Yahoo! searches. That would be hard to manage, so it would need to be automated, and maybe even self-serve, but I could see it producing a tiddy bit of revenue.
