In this post, we’re going to cover the following:

What the Change Looks Like

New Facebook Sidebar Ads

In the past, you may have seen as many as seven ads in your sidebar. All had a small image (100×72 for link thumbnails, 120×120 for photo shares and 128×128 for video thumbnails), making them easy to ignore.

Now, however, sidebar ads will be up to three times bigger, nearly as big as the content in the News Feed. Instead of being cluttered with ads from seven different brands, the sidebar will now focus on only one or two ad units.

In Facebook’s tests, this has resulted in far more engagement with these ads. This, of course, is great for advertisers!

How it Impacts Ad Creation

There has been a lot of confusion over this among advertisers. Many are checking Power Editor or the ad create tool, expecting to see something different in the way they create ads.

Nothing changes in the flow of creating ads. This isn’t a matter of rolling out functionality to ad accounts, for example. The rollout applies to users and what they see.

If you were previously creating ads using dimensions that apply to desktop and mobile News Feeds but send those ads to all placements, those ads will now be shown with the bigger sizes to those users who have received the rollout.

If you were previously creating ads using the old sidebar dimensions, however, those ads will continue to render smaller. For now, at least!

More on that later…

New Sidebar Ad Dimensions

First, know that this significantly simplifies ad creation. In the past, you’d need to do one of three things:

  • Create separate ads for sidebar and News Feed
  • Run your ad to all placements, but get a poorly cropped image in the sidebar
  • Optimize copy and imagery so one ad would look okay in all placements

Now, however, there is less to worry about. While the images will render larger in desktop and mobile News Feed, they will now have the same aspect ratio across all placements, including the right hand column. Those images will now scale accordingly.

On one hand, you could just create one ad that goes across all placements now without issues. To break down performance, of course, you’d use Facebook’s powerful ad reports.

But you may want to know the specific dimensions for these new sidebar ads. Here they are…

Page Post Photo, Link, Offer, Desktop App and Domain Ads:

  • Image Dimensions: 254×133 px
  • Consistent Aspect ratio: 1.91:1

Page Post Video Ad:

  • Image Dimensions: 254×143 px
  • Consistent Aspect Ratio: 16:9

Page Like or Event Ad:

  • Image Dimensions: 254×94 px
  • Consistent Aspect Ratio: 2.7:1

Note that this indicates a consistent aspect ratio for image and link shares, which is not currently the case. I’ve checked in with Facebook to get clarification.

How it Impacts Ad Delivery and Costs

Let’s think this through…

Bigger Sidebar Ads > Fewer Ads > More Competition > Higher Costs

Expect the following:

  • CPM price will go up significantly due to far less inventory and higher competition
  • CPC price will go up at least slightly
  • oCPM price will go up significantly

The price to reach users based on placement has never been equal. I’ve documented in the past how I’ve seen oCPM prices that are 50 times higher on mobile and 20 times higher on desktop News Feed than in the sidebar.

Expect that to change significantly. It may remain cheapest to reach users in the sidebar, but these costs will begin to even out.

However, those sidebar ads will also become more effective. In the past, I’ve found those right hand column ads to be worthwhile, even though the click through rate was awful. This was due to the low cost to reach users.

Now, costs to reach users will increase, but engagement should increase dramatically as well. When all is said and done, you may see very little difference in terms of Cost Per Action.

But we’ll need to wait and see. ALWAYS monitor your results. But this underscores the necessity to focus on Cost Per Desired Action, not secondary stats like CTR or CPM.

The 20% Rule

One pretty big pain for advertisers who create News Feed ads is the dreaded 20% rule. No ad image can include more than 20% text (inexactly measured with a grid).

Of course, this didn’t apply to the sidebar, which was nice. You could create small images with big text for the sidebar and not have any issues.

That now changes.

Going forward, the 20% text rule will apply to all ads, including sidebar ads with the new, bigger images. Actually, that won’t be enforced immediately.

More on that now…

The Rollout Timeline

Facebook notified Preferred Marketing Developers of the following timeline (shared by

  • June 24: We will begin rolling out the new RHC ad format. Ads that meet the specs for the new RHC ad format will automatically be rendered in the large format. Ads that are not eligible will render in the original smaller format.
  • From June 24 onwards: We will expect a moderate increase in CPMs as ads start rendering in the larger format. CPMs will increase over time as more advertisers adopt the new, larger ad format and stop using the original, smaller format ads.
  • August 1: All new RHC ads that are created on or after August 1 will be subject to the 20% text policy.
  • September 1: The 20% text policy will apply retroactively to existing RHC ads. We will also stop rendering the original, smaller format ads so all of your RHC ads must be updated by this time.

So my advice: Start creating your ads using the proper aspect ratio going forward. Get into the practice of considering the amount of text in sidebar ads, though that won’t be enforced immediately.
