The Key Elements of Successful Audience Optimization

May 10, 2018

Audience optimization is one great way to ensure your social ad campaigns meet your goals. However, what’s involved with optimization, and what things should you keep in mind to maximize the effectiveness of your campaigns?

In this article, we discuss the main elements of audience optimization and how to set your social campaigns up for success.

Audience Fatigue


Every audience has a life cycle. Depending on its size, budget, and campaign length, an audience will eventually grow tired of a campaign’s ads (i.e., fatigue). Naturally, a smaller audience
(< 80,000) will fatigue quicker than a larger one.

The most efficient way to avoid audience fatigue is to keep things fresh and strategize for new audiences every seven to 14 days. In other words, understand audience fatigue and be able to optimize to avoid it. Audience fatigue is when an audience is overused, resulting in a high frequency, costly CPM, and declines in performance.

Audience Overlap


Audience overlap is another issue that social marketers face on a regular basis. This is a result of ad sets from the same advertiser ending up in the same auction, bidding against each other, and inevitably damaging performance. Having overlapping audiences can lead to poor delivery of your ad sets.

Additionally, averaging a high Ad Relevance Score can often be difficult, especially if you’re constantly trying to avoid overlap and fatigue. Facebook calculates the Ad Relevance Score based on the positive and negative feedback an ad receives from its target audience. In short, if your Relevance Score is high, your audience wants to see it, and if not—well, something’s wrong.

Ad Creative for Audiences


Facebook allows you to create Engagement Custom Audiences from four ad types:

  • Canvas
  • Video
  • Slideshow
  • Lead generation


An Engagement Custom Audience (ECA) is a Custom Audience made up of people who’ve interacted with your content on Facebook. “Engagement” refers to actions like viewing your video or opening your lead form on Canvas. These four variations of ad creative are also the most customer-friendly and engaging ad types. Where it’s relevant to your campaigns, use these ad types as much as possible.

Using ECAs, you can retarget ads to people who’ve shown intent by interacting with your video, canvas, or lead gen form. You can also use Engagement Custom Audiences as a source for a lookalike audience, which will let you find people similar to those who’ve engaged with content on Facebook.

Audience Strategy


There are a vast number of audiences available to advertisers. Start building these audiences and using an audience tracker (this can be a simple Excel spreadsheet; see example below) to understand how often and when they were last used.

For example, you may have audiences compiled from:

  • The Facebook pixel
  • Your CRM data
  • Leads from Facebook content (videos, slideshows, etc.)
  • And more
