Marketing agencies in Columbus, Ohio: 263 offices, a consultancy surprise and an RFP you can copy

This page is for Columbus-area businesses and nonprofits looking for a marketing agency, people researching the local market, and vendors that sell to agencies.

Columbus agencies by the numbers

County Business Patterns (CBP) 2023, for the Columbus, OH Metro Area (CBSA 18140) and NAICS 5418, Advertising, Public Relations, and Related Services:

CBP counts locations with paid employees. It leaves out the self-employed, so a freelance designer or a solo consultant isn't in these figures, and a firm with two Columbus offices counts twice.

Agency or consultancy? The Columbus quirk

The Census Bureau puts firms that create and run campaigns in 5418 and firms that advise in 541613, marketing consulting services. In most metros the agencies are bigger. In Columbus, the 237 consultancies employ 3,719 people, about 15.7 each, against 9.3 at the agencies. If your problem is strategy, segmentation or pricing, you may be shopping in the consulting market without realizing it.

The metro also has 5 media buying offices, 4 media representative offices and 4 advertising distribution businesses. Custom SEO work is coded 541511, custom computer programming. The NAICS code for marketing page explains the boundaries.

Size and location

Of the 263 establishments, 157 have one to four employees, 43 have five to nine, 28 have 10 to 19, 26 have 20 to 49, 6 have 50 to 99 and 3 have 100 to 249. The Census Bureau doesn't publish the three largest size classes, but the published classes already add up to 263, so no Columbus agency office has 250 or more employees. In broader bands, 228 have fewer than 20 employees, 32 have 20 to 99 and 3 have 100 or more.

"Not reported" means the Census Bureau published Licking County's figure but flagged it as high-noise: the noise added to protect confidentiality changed it by 5% or more. The metro's other counties hold the remaining 3 establishments.

Local shop or a firm from elsewhere?

With only 9 Columbus offices of 50 or more staff, a large brand may also look at firms in other cities. A rough guide:

A request for proposal that gets comparable answers

Send three to five firms the same brief and ask for answers in the same order. This makes small and large firms easy to compare.

About us: [company, what we sell, to whom, in which markets]
The goal: [one measurable outcome and the date it matters by]
Scope: [channels and deliverables in scope, and what is out of scope]
Budget: [fee range] plus [media or production budget, if any]
Please answer in this order:
1. The team: names, roles and the share of our hours each would work. Which tasks go to freelancers or partners?
2. Two comparable clients we can call, including one that has since left.
3. Fees: hourly rates or a fixed fee by deliverable, how third-party costs are billed, and any markup.
4. Reporting: the metrics, how often, and access to the underlying data.
5. Ownership: confirm that ad, analytics and social accounts stay in our name and that you'll assign copyright in final work on payment.
6. Terms: the notice period and what you hand back when we part ways.
Deadline for questions: [date]. Proposals due: [date].

Why items 5 and 6 matter: Google says an agency "must set up a separate Ads account for you," and the Copyright Office explains that commissioned work is a "work made for hire" only in nine narrow categories with a signed agreement, so a logo or campaign needs a written assignment. On notice, Stagwell's 10-K says its contracts "typically provide for termination by either party within 30 to 90 days," with payment typically due in 30 to 60 days.

Selling to Columbus agencies

The buyers are few and reachable. Leaving out the 157 one-to-four person offices, 106 agency establishments have five or more employees, and 242 of the 263 are in Franklin or Delaware County. Their clients include large local advertisers: Bath & Body Works, headquartered at Three Limited Parkway in Columbus, reported advertising and marketing costs of $255 million for fiscal 2025 in its 10-K.

Illustrative example. The company and figures are invented.

Shelfwise (shelfwise.example) sells retail media reporting at $400 a month to agencies that run campaigns for consumer brands. In Columbus, 26 agency offices have 20 to 49 employees. If a third run retail or consumer brand work, about 9 fit, worth about $43,200 a year if all bought. The first email names a brand the agency has publicly listed as a client and the retail media reports it probably assembles by hand. Finding which nine is the account research Bebop does for each agency in a list; the general method is in how to build a prospect list.
