Referral ads are appearing in my normal ad unit

referral ads appearing in normal ad unit

[visu]

I am having 2 referral2.0 ad units and a normal adsense adunit(160x600) in a page.

For the past 3days i not getting any any normal contectual ads in the 160x600 ad unit instead of only one referrals 2.0 ad is appearing in that ad unit..

Will it happen normally?. Or i ve done any mistake while inserting the adsense code to my page..

I ve checked my page code twice .. i found it is in proper way. But it is confusing me why referral ads are appearing in my normal adsense ad unit.

anyone facing similar problem?

Part of a beta test maybe?

I saw it the other way around - normal ads appearing in my referral ads. After I saw that, off it went. Especially now that smart pricing could be set for referral ads - [webmasterworld.com...]
