Yesterday’s IAB announcement about the growth of ad networks had an interesting statement: “Interviews with online publishers, …, indicate that the lack of adequate pricing tools and inventory management discipline contributed to the growth in available ad space. This is causing publishers to seek out ways to sell large inventories of unsold ads.”
I’m sure the IAB study was generally talking about the display space. But as we’ve been saying on these pages for a while, if inventory management is difficult in the display space, it’s a disaster waiting to happen in the video space. Think about it. On a web site, inventory management is not that hard. Website ad inventory doesn’t change that frequently, or if it does, it is carefully changed, with lots of analysis of where the content should be, where the 300×250 ad should be located, where the skyscraper and leaderboards should be (above the fold, below the fold, etc.).
Once the site is created, it’s a matter of figuring out how many visitors (uniques and in total) are coming to the site. Inventory forecasting is limited to maintaining a database of the particular ad units, cataloguing them and forecasting the audience based on the last 30 days of traffic or some seasonal event.
Now, I’ve exaggerated the simplicity of the display world to make a point, but in the video world, things get much harder. The content is not static; it is syndicated to multiple sites, distributed in multiple formats. There are a myriad of ad formats and there is the fact that the syndication may be uncontrollable at times, at least in terms of the viewership. Add to this to the fact that the ad inventory itself is dynamic (maybe a pre-roll is better than an overlay for a particular piece of content), this becomes an issue that needs to be addressed by video ad networks.
One unrelated point I’ll make is that I will take a bit of issue with the point made in the article about lower CPMs from ad networks. Yes, in general, that’s probably true, even in the video space, but with the right ad management system or platform, content transparency, technology and automated optimisation systems, it need not be true all the time. I’ll save that topic for another day.
