The Google AdSense blog announced they have updated the layout of some AdSense units. The main changes were to make the ads “more space-efficient and visually pleasing,” said Google.
- Leaderboard (728×90): the title, description, and URL are now arranged in rows instead of columns (except in the case when only one ad is showing)
- Medium and large rectangles (300×250, 336×280): the URL is now in the same line as the title
- Font size changes to make them more readable
