Marketing agencies in Portland: 412 offices on both sides of the river, Oregon's opt-out rule and a scorecard

This page is for Oregon and southwest Washington organizations hiring a marketing agency, people researching Portland's agency market, and vendors that sell to agencies.

Portland in figures

Source: US Census Bureau, County Business Patterns (CBP) 2023, for the Portland-Vancouver-Hillsboro, OR-WA Metro Area (CBSA 38900) and NAICS 5418, Advertising, Public Relations, and Related Services. CBP counts establishments with paid employees, not companies, and excludes the self-employed. The employment and payroll totals carry a moderate noise flag: the Census Bureau's confidentiality noise moved them by 2% to 5%.

The county picture

Yamhill's employment was published but flagged as high-noise (the confidentiality noise moved it by 5% or more). Washington County, home to Beaverton and Hillsboro, averages about 21 employees per office against about 15 in Multnomah and under 7 in Clackamas. Clark County agencies register in Washington State, not Oregon, which matters when you check a firm's records.

By size, 280 establishments have one to four employees, 45 five to nine, 36 10 to 19, 33 20 to 49, 7 50 to 99, 6 100 to 249 and 4 250 to 499. The Census Bureau doesn't publish the two classes above 500 (it drops cells with fewer than three establishments); the total shows 1 establishment has 500 or more employees. So 361 have fewer than 20 employees, 40 have 20 to 99, and 11 have 100 or more, that last figure derived as the total less the smaller bands.

The kinds of agency

Advertising agencies (541810) are the core: 199 establishments, 2,278 employees and average pay of $112,866 (our calculation). PR agencies (541820) number 107, with 911 employees. Direct mail is small in count but not in size: 14 establishments with 462 employees. The rest are 56 promotional products and other services firms (541890), 20 display advertising firms (541850), 6 media representative offices (541840), 5 media buying agencies (541830) and 5 advertising distribution businesses (541870); their employment figures are high-noise.

Beyond 5418, the metro has 570 marketing consultancies (541613) with 3,696 employees and 297 graphic design studios (541430). Custom SEO and web development firms are coded 541511. If you're comparing an agency with a consultancy or design studio, the NAICS code for marketing page explains the boundaries.

A big advertiser in the suburbs

Nike, Inc., at One Bowerman Drive in Beaverton, reported demand creation expense of $4,754 million for its fiscal year ended 31 May 2026. Its 10-K says that line combines brand marketing, which includes advertising, media and digital marketing, with sports marketing such as endorsement contracts. Neither the holding companies' 10-Ks nor SEC listings show a public agency company headquartered in the metro.

Oregon's privacy law and your agency's tracking setup

The Oregon Consumer Privacy Act (ORS 646A.570 to 646A.589) took effect on 1 July 2024. The Oregon Department of Justice says that as of 1 January 2026, businesses and nonprofits that meet the Act's thresholds "must honor opt-out preference signals sent by Oregon consumers as a valid opt-out request," and must keep a clear and conspicuous opt-out link on their websites.

For an agency, this lands in the tag manager and the ad platforms. If the Act covers you, ask each finalist:

• How do your site tags respond to a browser's opt-out preference signal?
• When a visitor opts out, which pixels and audience uploads stop?
• Where is the opt-out link, and who tests it after each site change?

An agency that can't answer clearly will leave the compliance work to you.

Score the finalists the same way

Pick three to five agencies, send the same brief, and score each one on the same sheet before you meet the next.

Relevant work (x3): case studies in our category or channel, with numbers
The team (x3): named people on our account, their seniority and share of time
Measurement (x2): how they report, and whether we see the source data in our own accounts
Privacy and tracking (x2): clear answers on opt-out signals, consent and data handling
Ownership (x2): accounts in our name; copyright in final work assigned to us on payment
Commercials (x2): fees by deliverable or hour, third-party costs shown separately, notice period
References (x1): two similar clients, one former client
Total: (sum of score x weight) out of 75

Two notes on the rows. On ownership, the Copyright Office explains that commissioned work is a "work made for hire" only in nine narrow categories with a signed agreement, so ask for a written assignment. On commercials, Stagwell's 10-K says its contracts "typically provide for termination by either party within 30 to 90 days," which gives you a benchmark for the notice clause.

Selling to Portland agencies

Illustrative example. The company and figures are invented.

Tagwatch (tagwatch.example) sells a tag and consent monitoring service at $350 a month. Its pitch: Oregon's opt-out signal rule has made tracking audits a recurring job for agencies. It targets the 199 advertising agencies and 107 PR agencies, 306 in all, and assumes an illustrative 30% manage clients' websites or ad tracking: about 92 fits, worth about $386,400 a year if every one bought. The opener names a client site the agency built and offers a free scan of its opt-out behavior. Working out which agencies manage tracking means reading each firm's services and case studies, the research Bebop does for each account in a list. For method, see how to build a prospect list.
