Top SEO Agencies In Seattle For 2026

Compare 10 top SEO agencies in Seattle for 2026, from enterprise search firms to local, healthcare and WordPress SEO specialists, with services and best fits.

Choosing an SEO agency in Seattle is harder than it looks, because the city’s search market rewards very different strengths depending on who you sell to. A Ballard restaurant competes for map placement block by block, a Bellevue software company needs national rankings against rivals with big content budgets, and a regional health system has to grow organic visibility without breaking privacy rules. One agency rarely does all three equally well.

Seattle’s economy makes that competition sharper. The metro is home to major technology, retail and healthcare brands, and many local buyers have worked inside them, so they ask hard questions about technical SEO, analytics and AI search.

The field is also crowded with national firms, paid directory listings and freelancers. For a wider view of the market, our US SEO agencies hub collects our city and specialty lists in one place.

For this list, we only included agencies with a real Seattle address or team and SEO as a listed service, and we checked each one against its own website. The order reflects SEO depth, track record and fit. No agency paid for a spot.

Best SEO Agencies In Seattle In 2026

1. Portent — Seattle’s Long-Running Search Agency, Founded In 1995

Portent was founded in 1995, which makes it one of the oldest digital marketing agencies in the city, and it still runs its main office on 5th Avenue downtown, with a second office in Salt Lake City. Clearlink acquired the agency in 2017, and Portent has continued to operate under its own name.

SEO sits at the center of a wider service mix that also covers content strategy, paid search, programmatic, social, analytics, CRO and web development. On the search side, Portent lists technical site audits, keyword research, site structure and internal linking reviews, link building, local search and international search strategy. Brands shown on its site include Adidas, Lush, Princess Cruises, Kate Spade, Zillow and Tumi, and the agency was named a Moz Recommended Company in 2021 and a US Agency Awards winner in 2022.

Portent suits national and enterprise brands that want senior strategy, technical depth and an agency able to train their own staff. Small local businesses will usually find a better fit further down.

2. Add3 — Capitol Hill Agency Pairing Technical SEO With Large Paid Media Programs

Add3 is headquartered on East Pike Street on Capitol Hill and also has an office in Portland. The agency was co-founded by Brian Rauschenbach, who has worked in search since 1996, and Tim Wisner. It reports more than $150 million in annual managed media and an average client relationship of more than five years.

Add3 is best known for paid search and paid social, but its SEO practice is more technical than many media-led shops. Its listed services include indexability analysis, site architecture, structured data, site speed and mobile audits, and platform migration audits that protect rankings during a relaunch. It also offers generative engine optimization, international targeting, manual penalty recovery, local SEO and accessibility work. Brands shown on its site include Costco, Filson, Outdoor Research, IT Cosmetics, Realtor.com, Fred Hutch and Pagliacci Pizza, and it holds Google Partner Premier and Microsoft Advertising Select Partner status for 2026.

Add3 fits retail and consumer brands that already invest heavily in paid media and want organic search planned alongside it. Buyers who only need SEO may want a search-first specialist.

3. Wheelhouse DMG — HIPAA-Aware SEO For Health Systems And MedTech Brands

Wheelhouse DMG lists its address on West Commodore Way in Seattle and works with a remote team led by CEO Aaron Burnett. It describes itself as a digital marketing agency for privacy-first industries and says it has worked with medical device and healthcare brands for more than a decade.

That focus shapes its SEO work. Wheelhouse groups SEO with AI optimization and CRO in its Digital Strategy practice, and it runs search work through Lighthouse, a proprietary search intelligence platform. Its analytics practice builds HIPAA-compliant measurement. Clients shown on its site include Providence, Swedish, Fred Hutchinson Cancer Center, Delta Dental, Insulet and McKesson. In one published case study, Wheelhouse says it reversed a 68% traffic decline for Providence and grew organic traffic by 87%.

Wheelhouse is a clear choice for hospitals, health systems, medical device companies and other regulated brands. Businesses outside healthcare and privacy-sensitive categories will not get the full value of its specialization.

4. Odd Dog Media — Fremont Local SEO Team For Single And Multi-Location Businesses

Odd Dog Media has operated as a full-service digital marketing agency since 2008. Brothers Adam and John Broetje started it after running cDiver, an online community for commercial divers, and learning that building and promoting a niche community was digital marketing. The agency is based on North 36th Street in Fremont, describes itself as a team of about 15 people, and has added offices in Portland and the Salt Lake City area.

Local search is where Odd Dog stands out. Its local and multi-location SEO work covers location and service-area signals, citation and directory management, review generation guidance, benchmark tracking and reporting. The agency says it manages 4,722 local listings for clients, and it is upfront that local SEO usually takes at least six months to produce meaningful results. Clients shown on its site include UW Medicine, PCC Community Markets, Bonney Watson, a Seattle law firm and several local service businesses.

Odd Dog fits restaurants, retailers, healthcare practices and service companies with one or many locations across the Puget Sound.

5. Logic Inbound — West Seattle Firm With A Healthcare SEO Focus

Logic Inbound is based on California Avenue SW in West Seattle. It was founded by an executive team with a background in early-stage SaaS, led by CEO Vlad Mkrtumyan and COO Hayk Saakian, and the CEO’s bio describes a team of 25. Vice President of Operations Evan Fishkin previously worked as a Microsoft program manager in charge of SEO for MSN.

The firm says plainly that it specializes in healthcare SEO, though it also works with ecommerce brands, SaaS startups, enterprise sites and small businesses. Its local SEO work covers Google Business Profile optimization, citations and location-based keywords, and its reporting tracks rankings, traffic and leads from organic search. Logic Inbound also offers Google Ads, WordPress web design, CRO and AI optimization. It reports a 30-month average client tenure and publishes case studies, including a 1,140% organic traffic increase for a junk removal company.

Logic Inbound is a good fit for medical and dental practices, clinics and local service businesses that want a lead-focused SEO program. It sets expectations of three to six months before results start to show.

6. Actuate Media — Pioneer Square Agency Running Technical, Local And GEO Programs In-House

Actuate Media was founded in Seattle in 2016 and keeps its home office on 1st Avenue South in Pioneer Square. It has since added offices in Tampa and Orlando. The agency stresses that a 100% in-house team handles SEO, GEO, Google Ads, social advertising, programmatic and OTT, and website design, and partner Brad Holly reviews every program it takes on.

Its SEO program includes technical audits and implementation, keyword and content strategy, generative engine optimization, AI Overview visibility and monthly reporting, with digital PR available as an add-on. Actuate serves home services, healthcare, legal, ecommerce, SaaS, professional services, automotive, travel and nonprofit clients. It holds Google Premier Partner status, is a Semrush agency partner, and was named a Clutch Top SEO Company in Seattle for 2023.

Actuate suits small and mid-sized businesses that want SEO and paid media from one team without being locked in. It charges no setup fees and does not require long-term contracts, which lowers the risk of trying a new agency.

7. Voglio — Belltown Performance Agency For Lead Generation And Ecommerce Brands

Voglio has operated since 2015 from its office on 1st Avenue in Belltown. CEO Alex Murray leads the agency, which was named one of Built In’s Best Places to Work in Seattle for 2024 and is SOC 2 Type II certified, a credential that matters to clients with strict data security requirements.

Voglio is a performance marketing agency first. SEO, AI optimization and GEO sit inside its performance management practice alongside paid search and paid social, and its reporting practice builds sales funnel reporting, lifetime value models and growth forecasts. It also runs affiliate programs. The agency says it serves lead generation and ecommerce websites across all major verticals, and brands shown on its site include BrainPOP, General Assembly, Clio, HealthEquity, Fetch Pet Insurance, Simms and Bond Vet. Its site also lists client companies that were later acquired, including BrainPOP and General Assembly.

Voglio fits funded companies that want SEO judged on revenue and customer value rather than rankings alone.

8. Bonsai Media Group — Lake Union Studio Combining Umbraco Website Builds With SEO

Bonsai Media Group was founded in 2008 by Jason LaBaw with co-founders Gus Zadra and Elliott Omlin. It started as a web design studio that built sites to be search-optimized from launch, expanded into full digital marketing in 2016, and moved to its current office on Westlake Avenue North by Lake Union in 2019. Development teams in India, the Philippines and Ukraine support the Seattle headquarters.

Bonsai describes itself as a full-service agency offering SEO, web design and development. Its services also include online advertising, Amazon marketing and ecommerce, web application development, branding and video. The agency has built on the Umbraco CMS since 2011, and it now focuses on enterprise CMS websites, 3D, AR and VR tools, and AI for manufacturers of high-ticket, configurable products such as boats.

Bonsai is a strong match for manufacturers and organizations planning a site rebuild that want SEO built into the platform from the start. Companies that only need an ongoing SEO retainer on an existing site may prefer a search-only firm.

9. Seattle Organic SEO — Founder-Led Small Business And WordPress SEO Since 2010

Seattle Organic SEO has operated since 2010 and was built by Brandon Na, whose earlier roles at Amazon, Expedia and DoubleClick shaped its approach. The firm started by helping local professionals such as opticians, photographers and real estate businesses get found online, and it still lists a Seattle mailing address on South Charles Street.

Its services include local SEO, WordPress SEO, SEO audits, content optimization, analytics and reporting, and AI SEO and GEO for small and mid-sized companies. WordPress work ranges from blogs and small business sites to WooCommerce stores, and the firm also offers website design and PPC management, with PPC management available for ad budgets from $1,000 a month. New clients can start with a free 30-minute SEO audit.

Seattle Organic SEO is a sensible choice for owner-run businesses on WordPress that want direct access to an experienced practitioner. Larger organizations that need a big team across many channels should look higher on this list.

10. Marketeering Group — Capitol Hill SEO And WordPress Partner For Growing Businesses

Marketeering Group works out of The Cloud Room on 11th Avenue on Capitol Hill. It focuses on small and mid-sized businesses and says it keeps a full team of in-house specialists across each area of digital marketing it offers.

Its digital marketing services cover strategy and consulting, search engine optimization, content marketing and PPC, with a separate SEO for AI offering for businesses that want visibility in AI search tools. The other half of the business is websites: WordPress builds, hosting and maintenance, speed and performance work, and accessibility and compliance. Marketeering is a Semrush certified agency partner, a WP Engine Preferred Partner and a Kinsta agency partner, and Expertise.com has recognized it among Seattle’s top SEO and content marketing agencies. Testimonials on its site come from Seattle-area businesses including Cedar’s Restaurants, Sync Fitness and Beeline Charters & Tours.

Marketeering fits growing local businesses that want one partner to run their WordPress site and their SEO together. Enterprise brands with complex platforms will likely need a larger agency.

How To Choose An SEO Agency In Seattle

Seattle has no shortage of agencies that promise first-page rankings. These questions will help you separate firms with real local depth from those selling a template. For a broader checklist that applies in any market, see our guide on how to choose an SEO agency in your city.

Does The Agency Have A Real Seattle Presence?

Many national firms publish Seattle pages without anyone working in the region. Check the address on the agency’s contact page and look it up on a map, because a suite number at a shipping store is not an office. A team that knows the difference between searchers in Bellevue, Tacoma and Capitol Hill will build better local pages and pick better keywords.

What Kind Of Business Does It Rank Best?

The agencies on this list have clear strengths: healthcare, local service businesses, retail brands, manufacturers or venture-backed companies. Ask for two or three case studies from businesses like yours, with the starting point, the work done and the results over time. An agency that wins map placement for a Fremont dental office may not be the right partner for a SaaS company competing nationally.

How Does It Handle Technical SEO And AI Search?

Seattle buyers often run complex sites on headless platforms, enterprise CMSs or large ecommerce stacks. Ask how the agency audits crawlability, structured data, site speed and migrations, and who implements the fixes. Then ask how it approaches visibility in AI tools such as ChatGPT and Google’s AI Overviews; a credible answer ties it to content, site structure and authority.

How Is Pricing Structured?

Seattle agencies price by monthly retainer, by project or by the hour, and contract terms vary from month-to-month to twelve months. Ask what the retainer covers in hours or deliverables, whether setup or audit fees apply, and how much notice you need to give to leave. Our breakdown of how much SEO costs explains typical ranges so you can tell whether a quote is in line with the market.

Who Does The Work And How Is Progress Reported?

Find out whether the senior people in the sales meeting will work on your account, or whether it moves to a junior team or an offshore partner. Ask to see a sample report. Good reports tie rankings and traffic to leads, sales or patient actions, and explain what was done that month and what comes next.

Conclusion

Seattle’s search market is demanding because its buyers are. The agencies above range from long-established firms such as Portent and Add3 to specialists in healthcare, local search, performance marketing and small business WordPress sites. The right choice is the firm that has already solved a problem like yours.

Before you sign, ask for a written audit of your site, confirm who will manage the account, and make sure the contract length matches a realistic timeline for results. SEO takes months to pay off, so choose a partner you trust to explain the work clearly.
