Fewer ads mean less clutter
Facebook is doing even more streamlining. In addition to the recent changes to Facebook pages to look more like personal profile pages, Facebook is now making changes to Facebook ads. In the past, you could upload different size images for right rail Facebook ads vs. timeline ads. If you uploaded an image that was at least 90 x 90 pixels, the ad would be displayed on the right rail/column and mobile (only). The image needed to be at least 600 x 315 pixels to display in the timeline.
Making It Simple
In an effort to simplify things, Facebook is moving to a single image size and a single desktop ad size whether the ad is displayed in the timeline or right rail/column. In the past, if you didn’t like the way Facebook automatically resized your image, you would have to create 2 separate images for timeline and right rail ads.
As part of the streamlining process, Facebook is increasing the ad size in the right rail. Therefore the image will not need to be resized regardless of where the ad is displayed (except for mobile which will remain a smaller ad format).
Are There Any Other Implications?
Larger ads in the right rail mean images with text such as logos may actually be legible. This is great from a brand perspective as the current ads in the right rail often force logos with text to be rendered so small that they are illegible. Larger ads also mean fewer ads in the right hand column. Fewer ads mean less clutter, so your respective ad has the opportunity to stand out more. However, fewer ads also mean that most likely the cost to advertise will go up. But with CPC prices so low on Facebook, I would assume that a small price increase won’t break most budgets.
