In the middle of the night I visited a dutch but and sell website searching for something specific. The search results, page after page, were filled with advertisements from the same auction agency. My single visit, clicking though 20 pages produced well over a thousand ad impression. I had to click though them to find other peoples ads. The next day they were all gone. Apparently the budget ran out.
