From the beginning, Philip Kaplan has touted AdBrite's ad stats on the ad network's homepage. Today, it proclaims "470 million impressions a day on 54,328 sites." Which sounds impressive enough.

AdBrite's pageviews have grown by less than 50 percent, while its customer base has expanded sevenfold. More customers, more costs; even on the Internet, catering to small fry gets expensive. If ad networks are a scale business, AdBrite has been growing the wrong number.
