Some agencies don’t just bring value in terms of directly managing a single ad platform for a client, but can help strategize and provide insights that could shift ad strategy all together. A great agency should be able to you help optimize your FB ads quickly, but if the ROI isn’t taking shape or spend isn’t efficient after consistent optimization, they should be able to talk through that with you and possibly take a different ad approach based on your target audience. Maybe Snapchat Ads is a better platform if you’re targeting 18 – 26 year olds, or LinkedIn if you’re going after professionals.

So that’s a core benefit to using agencies: they may/should know more than one platform and can help you make good strategy decisions that are best for your business.
