Adsense, Google’s partly contextual advertising solution for publishers, recently launched their biggest ad size.
The 300×600 ad format allows for more of the so called brand-friendly image ads that other advertising networks often offer to advertisers. These are popular due to their size and potential impact on readers, they are pretty hard to miss. However, it looks like some publishers have gotten a little carried away as the company posted on their Adsense blog today that there is a restriction of one per page.
I’d imagine some of the more aggressive publishers put a few in a row at the top of their pages and hoped people would click an ad long before getting to any content. I’ve been messing about with them a little and the verdict is still out. It will probably take a while for them to get a full inventory in the size for images. The text ads look pretty bad in this format I think, especially if just one up the top…it should really auto-shrink down.
You can read the details on the blog.
The same blog has also announced some new publisher focussed Adsense in Your City dates, again full details can be found at Inside Adsense.
