Inventory + EPC

[markus007]

Lets say adwords advertisers are willing to buy a total of 2,400 clicks a day for the term loans every day from adsense sites. Those 2,400 clicks are going to be spread out into 24 hours blocks. Now assuming there are 50,000 clicks a day coming from adsense a day for the term loans, what will happen?

I think that adsense assigns high value clicks to sites it deems trusted ie not as much smart pricing occuring. The remaining 40,000 some clicks will then be broadmatched to lower paying terms. I think when people are screaming drop in epc etc, what they are really seeing is a shift in inventory and targetting on large publishers sites or gmail etc.

This is a great point. We typically look at what only the advertisers doing in bidding / content off, etc.

When all day different publishers are driving the high priced clicks / epc swings

I have a breakdown of terms via channels (extra features that normal users don't have) I'm pretty sure this is exactly what is happening when looking at my data.

I think it's more likely that Google would divert inventory to publishers whose referrals can be expected to convert better (either because of historical data or the themes of the sites). In other words, it would make more sense for Google to send a high proportion of widget ads to sites like widgetreview.com or steves-widgets.com than to mass-market portals, news sites, weather-forecasting sites, etc.
