Marketing agency roles explained: Who does what in 2025?

Once upon a time the lines were clear: branding agencies built the identity, advertising agencies ran the ads, and marketing agencies filled the space in between. Fast forward to now, and those borders barely exist. Clients want one agency that can do it all, so agencies stretched—and job titles multiplied.

Advertising still spans traditional outlets, but now websites, search engines, and social platforms are in the mix too. PPC managers, media buyers, and sales leads all balance spend together. Branding has expanded beyond logos and style guides to include digital storytelling, creative strategy, and even influencer collaborations. And digital marketing agencies? They’ve absorbed it all, layering content, SEO, social, and analytics into one unified operation. 

Why understanding agency roles matters

As single agencies absorb the tasks of three, role clarity becomes even more important than ever. Most teams benefit from seeing roles in two distinct categories: structure and output. Agency management roles (structure) keep client accounts steady, expectations clear, and the business running smoothly. While agency execution roles (output) deliver the work. Think creative strategies, campaigns, and results that keep your clients happy.

Why does the distinction matter? Because blurred lines create strain. A content strategist shouldn’t be spending their time calming a client crisis, and an account manager doesn’t belong knee-deep in keyword research. When those responsibilities get mixed, both the work and the relationships start to fray.

The biggest contributor to our growth is our people. We bring on smart, driven, and talented individuals who align with our North Star of helping people feel proud, prosperous, and connected.

Core marketing agency roles

Now that we have an understanding of why agency roles matter, let’s take a look at some of the most common roles that exist at the majority of agencies. These are your agency’s starter pack. The roles that handle the talking, the doing, and the growing.

Account manager

Forget the word “account” because this role is about people. The best account managers know clients like old friends, catch the little things before they blow up, and somehow keep everyone calm even when things get messy. 

What does an account manager do at a marketing agency?

• Keep client conversations moving so nothing important gets lost.

• Translate client goals into marketing initiatives your team can run with.

• Work closely with the sales manager to spot when a casual chat is really a new opportunity.

• Balance what clients want with what your team can realistically deliver.

Client trust is everything, so this role deserves an early spot on your team. But if you’re still the one answering midnight texts? That’s your cue to bring in someone dedicated to holding that trust day to day.

Project manager

Deadlines don’t manage themselves—and neither do budgets or deliverables. A project manager stays on top of it all, so marketing campaigns actually launch on time.

What does a project manager do at a marketing agency?

• Build clear timelines and milestones for client projects.

• Keep project management systems updated to support smooth operations.

• Coordinate with designers, strategists, and sales to keep work moving.

• Spot risks and bottlenecks early, before they derail delivery.

Bring in a project manager before overlapping deadlines start colliding—it’ll keep your creative team from living in constant overdrive.

When you're building a company, you don't want to hire all the same types of people. Just like in a recipe you need different ingredients to make a dish shine. The biggest challenge was people. Not just finding the right people, but ensuring that we had the right mix of people and then supporting their individual needs while staying focused on the company as a whole.

SEO specialist

SEO specialists help your clients show up in search results. They know what it takes to get content noticed, why rankings shift overnight, and how to keep a digital marketing strategy from slipping to page three.

What does an SEO specialist do at a marketing agency?

• Dig up the keywords your client’s competitors missed and use them to fuel content creation.

• Polish titles, headers, and links so search engines notice your marketing efforts.

• Catch technical issues before they tank a client project.

• Spot industry trends early and pivot marketing initiatives while others are still scrambling.

Add an SEO specialist as soon as organic growth is part of your pitch to clients. If “we’ll get you ranking” is on the table, you need someone who knows search engine optimization inside out.

Content strategist

A content strategist is equal parts storyteller and planner. They’re the ones connecting written content, social media graphics, and video content back to a bigger marketing strategy.

What does a content strategist do at a marketing agency?

• Create content calendars to keep blogs, emails, and social channels on schedule.

• Ensure messaging stays consistent across every piece of content

• Work closely with the creative team to turn creative ideas into campaigns that clients actually notice.

• Track performance and adjust marketing initiatives before anyone has to ask.

Bring in a strategist as soon as your agency starts publishing across channels. They’ll tie everything together early, before scattered messaging turns into lost client trust.

PPC manager

Paid ads look simple on the surface—write some copy, set a budget, wait for clicks. But anyone who’s run a campaign knows it takes a PPC manager to make it profitable. This role blends strategy with constant fine-tuning so your paid campaigns bring in more than they cost. 

What does a PPC manager do at a marketing agency?

• Research and select keywords that drive marketing campaigns forward.

• Write and test ad copy across search engines and social media marketing platforms.

• Adjust bidding strategies to protect budgets and maximize ROI.

• Track performance daily and pivot marketing initiatives before clients start asking questions.

Don’t wait until ad spend is wasted. If paid media is part of your services, this role should be one of your first hires. Guesswork and Google Ads don’t mix.

When people feel valued and cared for, they naturally deliver their very best work. This culture can also help your agency grow, attracting top talent by showing people what you do to support your staff and that you truly respect their needs.

Creative director & designers

A creative director sets the vision, and the designers—graphic designers, web designers, video editors—bring it to life.

What do the creative director and designers do at a marketing agency?

• Shape brand identity so campaigns feel consistent, not cobbled together.

• Create social media graphics, ads, and layouts that catch attention fast.

• Build and refine websites that carry brand messaging all the way through.

• Produce video content and handle video editing for social media marketing.

Bring them in full-time once freelance fees start creeping towards an annual salary. A dedicated designer frees up strategists and account managers to focus on their own roles while keeping campaigns polished from the start.

Supporting & emerging roles in 2025

Now let’s take a look at some of the newer roles that are gaining popularity at marketing agencies. These roles don’t always get called “core,” but for agencies that want to stay ahead and impress clients, we think they should be.

Marketing automation specialist

Marketing automation used to be a perk. Now it’s how even the smallest firms grow. Automation specialists keep the tech running behind the scenes so clients see faster responses, smoother campaigns, and better results. Explore marketing agency software that automates without adding sprawl.

What does a marketing automation specialist do at a marketing agency?

• Set up email, CRM, and project workflows that run on their own.

• Segment audiences so campaigns feel personal, not copy-paste

• Take repetitive tasks like reminders, reporting, and lead nurturing—and make them automatic.

• Sync tools with the digital marketing team so automation supports bigger business operations.

Add this role when campaigns scale beyond what your team can manage manually. If account managers are stuck scheduling emails instead of managing client accounts, it’s time.

Data analyst

Analysts are the storytellers behind the spreadsheets. They know when a spike in traffic is worth celebrating, when it’s just bots, and how to connect all the data back to business growth.

What does a data analyst do at a marketing agency?

• Build dashboards that track marketing campaigns across search engines, social media marketing, and paid ads.

• Translate raw data into reports that clients can actually understand.

• Spot industry trends and revenue strategies that give your agency an edge.

• Work closely with account managers and the sales team to connect results with business development.

Bring in an analyst before you think you need one. It’s the leap that turns “here are your results” into “here’s why you should stick with us instead of shopping around.”

AI specialist

AI had its shiny-new-toy moment. Now it’s baked into everything from content to analytics. An AI specialist is the one who keeps it useful, not messy.

What does an AI specialist do at a marketing agency?

• Evaluate and roll out AI tools across content creation, reporting, and social media management.

• Make sure automation speeds things up instead of slowing everyone down.

• Keep an eye on compliance and privacy rules before they become client headaches.

• Guide the marketing team so AI elevates the work instead of watering it down.

Add this role when your team is experimenting with multiple AI tools and has no clear strategy. An AI specialist turns scattered experiments into results, without the rework.
