A quick review: Conversion tracking is a way to monitor the amount of money you spend on a Facebook ad campaign and the amount of money you make back.
In this campaign, we spent $294 advertising to the aggregate mailing list. With 28 orders at a cost of $10.31 per order, we made $3,400 worth in orders. Our website purchases reflect that: the return on ad spend is 11.7x. For every dollar that we spent on that particular audience, we got $11.72 back in gross ticket sales.
When you’re using A/B testing in your campaigns, you'll see that not all ad sets, or audiences, have an equal return on ad spend and customer acquisition costs. Some audiences are more profitable to advertise to than others.
Why is this important? If you have a limited budget for Facebook ads, that budget needs to be spent on ad sets or ad creatives that drive ticket sales. In other words, that budget needs to go toward serving ads to the fans interested in your event.
Enter budget optimization. Budget optimization is how you reallocate budget from losing ad sets to winning ad sets, or losing creative to winning creative. It’s a no-brainer. When you run a campaign, you want to include budget optimization.
The basic principle of budget optimization is smart allocation. You’ll spend less on audiences with high customer acquisition costs and more on audiences with low customer acquisition costs, all of which brings in more money.
What does this look like? In the A/B Testing video, we looked at a $100 budget that initially brought in $50 in revenue. By using multiple ad sets and creatives, by dividing the budget equally between two ad sets, that same budget brought in $300.
Let’s bake budget optimization into that campaign. With a third-party tool like ToneDen, which uses an automated rule set to move budget from losing audiences to winning audiences, that same $100 dollars would make $450 back.
How did we spend that same $100, on the same audiences, with the same creative, but get $150 more in sales? Instead of evenly splitting that budget between ad set one (interest audience ads) and ad set two (mailing list and traffic audience), we spent $25 less on the first ad set and funneled an extra $25 to the second ad set, the better performing of the two. We made more sales and, because we spent more budget on a more profitable audience, we sold more tickets. And this is budget optimization in practice. It can be done manually or through automated methods (ToneDen has its own automated budget optimization algorithm).
Now that you're familiar with Budget Optimization, let's talk about how to use multiple audiences in your campaigns:
