Better yet, they could do keyword matching based on popular topics, especially those which get confined to recurring "general" threads by moderator fiat. Data on keyword-to-ad matches could be collected automatically. The server would analyze thread content immediately before serving it, find the most frequently used words or phrases, generate a cookie to be included in ad clicks, and correlate whatever feedback the ad vendor provides with all of the above. If the vendor is 4chan itself, this could all happen in real time so long as they had the CPU cycles available.
