What does a marketing department do?

A marketing department finds the people who need what you sell, gets your offer in front of them and turns their interest into leads and customers. Then it measures what worked and does more of it. That is the whole job, repeated every day.

The U.S. Bureau of Labor Statistics puts it in one line: marketing managers "plan programs to generate interest in products or services." Behind that line sit six jobs. Here is what each one is, what it produces and who usually does it.

The six jobs of a marketing department

1. Market research. Who buys, why they buy and who else they are looking at. Research covers customers, competitors and the searches people actually type. O*NET, the U.S. Department of Labor's occupation database, describes market research analysts as people who "seek and provide information to help companies determine their position in the marketplace." Without research, every other job is a guess.

2. Creative. The ads, the headlines, the images and the posts. Creative turns what research found into words and visuals that make the right person stop and click. It also means writing many versions, because the first idea is rarely the best one.

3. Landing pages. The page someone sees after they click. A good landing page says the same thing the ad promised and makes the next step easy, such as a form, a sign-up or a demo request. Google's own help pages say landing pages that rate well "are usually well organized and have text that relates to a person's search terms." This is where interest becomes a lead.

4. Campaigns. Launching the ads in the right channels, choosing who sees them and keeping them running. Campaign work is daily: new searches to target, weak ads to pause, new ads to test, posts to schedule.

5. Budget. Deciding where the money goes and moving it as results come in. On Google Ads, for example, you set an average daily budget, "the average amount that you set for each ad campaign on a per-day basis." Someone has to decide which campaign earns more of it this week and which earns less.

6. Reporting. What changed, what it produced and what happens next. Reporting closes the loop: it tells the founder or the leadership team where the leads came from, and it tells the department what to repeat.

What each job produces

Each job has an output you can point to.

• Research produces a clear picture of the buyer, the competitors and the searches worth going after.
• Creative produces ads and posts that are ready to run.
• Landing pages produce leads: names, emails and requests from people who want to hear more.
• Campaigns produce reach and clicks from the right people, every day.
• Budget work produces more leads from the same money, because spend follows what is working.
• Reporting produces learnings. Every week the department knows a little more about what brings customers, and the next week starts from there.

Put together, the department's real product is leads and customers, plus the learnings that make next month better than this one.

The roles that usually cover these jobs

In a company that hires its own team, these jobs are split across a handful of roles. Titles vary a lot from company to company, so treat these as typical descriptions, not a fixed org chart.

• Marketing manager or head of marketing. Sets the plan and ties marketing to the company's goals. O*NET lists the core task as to "formulate, direct, or coordinate marketing activities or policies to promote products or services." In a first hire, this person often does every job below too.
• Market research analyst or marketing specialist. Gathers data on customers and competitors and turns it into findings the team can act on. O*NET's task list includes to "prepare reports of findings, illustrating data graphically and translating complex findings into written text."
• Copywriter and designer. Write and design the ads, posts and pages. O*NET's graphic designer profile lists titles from "Brand Designer" to "Production Artist".
• Web or landing page designer. Builds and fixes the pages people land on, and improves them based on testing and feedback.
• Paid media or performance marketer. Runs the ad accounts day to day: campaigns, bids, budgets and tests.
• Social media manager. Plans, writes and posts on the company's social profiles.
• Analyst or marketing operations. Tracks what each campaign produced and builds the reports.

Some companies hire these roles in house, some hand part of the work to an agency or a freelancer, and many founders do it all themselves in the evenings. Each route can work. The common thread is that someone has to do all six jobs, every day.

How to have a marketing department without hiring one

There is a fourth option next to hiring, an agency and doing it yourself: an AI marketing department that does the six jobs for you.

That is what Bidhelm is. It researches your market, builds your ads and pages, runs your campaigns and social account, and reports on every change. In practice:

• You connect your account. Connect Google Ads or your X profile and start a 14-day free trial. Bidhelm reads the account, learns your business and gets to work.
• The first report lands the same day. What was found, what was fixed first and what comes next, on the day your trial starts.
• It does the work, not just suggests it. Bidhelm makes changes without waiting for a yes on each one, and every change comes with a plain-language reason. Recent changes can be undone from chat.
• Landing pages included. It builds a landing page for each ad, and the leads go back to Google Ads as conversions, so it can find more people like them.
• You always know what happened. A weekly report, plus every change in History as it happens.

If you are a founder weighing your first marketing hire, it gives you a full marketing department from day one: see Bidhelm for startups. If you already have a team, they set the direction and Bidhelm does the daily work. The four ways to run your marketing are side by side on one page.

Who this fits

It fits companies that want their marketing run for them, from a first campaign to a growth team spending at scale. You set the goals and the budget, and the work happens every day.

If some changes need a sign-off first, set them to ask first under Settings › Permissions, and Bidhelm waits for a yes before they go live. See Permissions.
