Recently one of my sites ranked top 10 for a competitive World Cup phrase. The phrase definitely was a contender for Google’s QDF model.
The day of the opening game, I included an iFrame with dynamic content. Within a few hours the page dropped to position 31st. After 24 hours, we removed the iFrame and our ranking returned within 12 hours.
I’m still baffled by this. Can an iFrame cause a penalty? If so, does the size and position of the frame matter?
