You’ve devised the perfect Facebook strategy and you’re ready to launch a campaign. You have the right message selected and the creative nailed down.

But how do you know that your campaign will see results? Is it based on an educated guess? Or do you have solid evidence and insights from past campaigns to expect a return on investment?

There’s much more to launching social media campaigns in hopes that they will meet goals and lift ROAS (return on ad spend).

While some marketing agencies have the expertise and bandwidth to execute campaigns effectively, it can be a challenge to drive insights and optimizations thoroughly in-house.

Joining creative efforts with skilled media buying can drive high-impact results.

We broke down the top reasons a creative marketing agency can benefit from a dedicated media partner in this ever-changing digital advertising industry.

Media buyers are the missing piece of the puzzle

Media buyers have years of experience under their belts, optimizing and executing campaigns. They’re the numbers people behind creative ads circulating the internet.

As a creative agency working with a media partner, you’re able to operate alongside a team of expert media buyers immersed in the advertising industry. They may not create the ads, but they know how to take those campaigns and make them profitable.

Consider dayparting for example.

We all know that profits vary during the day. Dayparting is the practice of running ads at specific times of the day or week to effectively target an audience.

Media buyers are able to tap into which hours are most effective for your industry and your message based on historical insights and audience testing. For instance, your audience might respond better to a certain message in the morning versus a different one in the evening.

A media partner is an extension of a creative agency, not only ensuring that campaigns operate smoothly but also that budgets are scaled efficiently to reach the best outcomes.

Data-driven campaigns outweigh the competition

It’s no secret:

We’re in the age of analytics, and not having a data-driven strategy can really hurt you.

Partnering with media experts means joining the creative component of marketing to mathematics. Media partners are more than a team of media buyers, though — they’re comprised of data scientists and engineers discovering the best ways to execute campaigns and even uncovering untapped audiences.

By utilizing historic campaign insights and best practices to guide campaigns, you’re able to determine clearly what’s working and what isn’t. For instance, does your audience respond more positively to shorter messages? Or perhaps it’s video that receives the best results.

A media partner answers those questions. Not only are you able to realize which campaigns have been successful, but you’re also making decisions based on actionable data.

Media buyers and creative agencies share the same goal

A media partner is an extension of a creative agency. Media partners are like scientists. They’re the data-driven experts who find the most profitable avenues for a campaign.

Without a dedicated media partner, creative agencies risk shooting in the dark and missing their target.

Media buyers have one goal and that’s to help creative agencies reach theirs.

If you’re in the market for a media partner, ask yourself these questions:

• Does your team have the expertise to execute, manage and monitor campaigns including budget and performance for the most efficient results?

• Will a media partner solve or rectify bandwidth problems?

• Do you have access to the right tools to create and manage campaigns in-house?

Ask yourself what’s best for your company goals

Whether you’re executing campaigns in-house or looking to partner with media experts, at the end of the day, it’s all about choosing a solution that aligns best with your campaign goals.

If you’re in the market for a media partner, choose one wisely and look for one that has proven results and technology that will be worth your investment.
