Manufacturing SEO is a different discipline from the SEO most agencies sell. The buyer is an engineer or a procurement manager rather than a consumer, the search terms are part numbers, tolerances and process names rather than brand keywords, and a single RFQ can be worth six or seven figures. A campaign that produces 300 visits and two qualified quote requests has done its job. A campaign that produces 30,000 visits and none has not.
That makes the choice of agency unusually consequential. A generalist shop will optimize a contract manufacturer’s site the way it would a dental practice, chasing volume and ignoring the fact that the words a mechanical engineer types into Google look nothing like the words a marketing intern would guess. The firms that do SEO for manufacturers well tend to employ former engineers, publish case studies with revenue figures rather than traffic charts, and understand why a website needs a CAD download and a tolerance table before it needs a blog.
The twelve manufacturing SEO agencies below were selected on how central industrial work is to the business, the specificity of the published results, and the depth of the team. Nine are in the United States, two in Canada and one in the United Kingdom, and they range from pure-play industrial boutiques to large performance agencies with a dedicated OEM and distributor practice. Each entry says plainly what the agency is strongest at, and the guidance further down covers how to match that to your own situation.

Best Manufacturing SEO Agencies In 2026
1. Gorilla 76 — Twenty Years Serving Only The Manufacturing Ecosystem, With Pipeline Figures To Show For It
Gorilla 76 was founded in St. Louis in 2006 by Joe Sullivan and Jon Franko and now runs as a fully remote team of around 35. It works exclusively with B2B companies in the manufacturing ecosystem, and it names its ideal clients precisely: engineering-heavy OEMs, custom machine builders, contract manufacturers, robotics integrators and Industry 4.0 technology companies with complex, customized products and a consultative sales process.
What sets the agency apart is that it reports outcomes in pipeline and revenue. An industrial oven manufacturer is credited with 9 million dollars in pipeline, CK Power with a 150 percent lift in online leads and 800,000 dollars in quarterly revenue, and Korte Company with a 650 percent increase in monthly contacts over two years. SEO sits inside a broader program of messaging, content, website transformation, targeted advertising and AI search optimization. Gorilla 76 also runs The Manufacturing Executive Podcast and publishes an Industrial Marketing Learning Center, and it is transparent about cost: monthly programs run from roughly 5,000 to 10,000 dollars with a one-year minimum, and a full-scale program including media is quoted at 200,000 to 300,000 dollars a year.
Gorilla 76 suits a mid-sized manufacturer with a long sales cycle that wants search treated as one input into a measured revenue program rather than a standalone retainer.
2. Windmill Strategy — Woman-Owned Industrial Agency With Published Pricing And Six-Fold Lead Gains
Windmill Strategy is a Minneapolis agency founded in 2006 and led by Kathy Kassera Mrozek, and it is certified as a woman-owned business through WBENC. It describes itself as a B2B industrial web design and digital marketing agency for technical, industrial, life science and manufacturing companies, and the client list backs that up: Minnesota Rubber and Plastics, Kongskilde Industries, Intek Plastics, FasTest, Halco USA and SuperMax Tools among them.
The published results are specific. A modular structures manufacturer saw organic form submissions rise 600 percent after SEO and structured data work, a welding equipment manufacturer more than tripled its first-page keywords, and a precision filtration company lifted organic submissions by 63 percent. Windmill is also one of the few agencies in this list with a full pricing page: ongoing digital marketing runs from 4,000 to 15,000 dollars a month with a recommended six-month minimum, a strategy quick start costs 5,500 dollars, and website redesigns start around 40,000 dollars. The agency is a Google Partner and a HubSpot, Shopify and WP Engine partner.
Consider Windmill if your site needs rebuilding as well as ranking, or if you want to know the price before the first call.
3. Weidert Group — Employee-Owned Since 1980 And Among The First Twenty HubSpot Partners In The World
Weidert Group has been marketing for industrial companies from Appleton, Wisconsin, since 1980, which makes it the oldest firm on this list by a wide margin. It is 100 percent employee-owned through an ESOP, fields 28 marketers whose leadership averages 29 years of experience, and holds HubSpot Diamond status as one of the first twenty partners HubSpot ever signed. Its four verticals are advanced manufacturing, engineering and technology, B2B professional services, and supply chain and logistics.
The case studies read like a manufacturing CFO wrote them. Falcon Structures generated 738 marketing-qualified leads and 31 new customers, Pumptec grew sales 39 percent and average customer value 89 percent while shortening the sales cycle by a third, Strouse lifted quote requests 90 percent year on year, and Gordon Flesch attributed more than 5 million dollars in revenue to the program over two and a half years. One contract manufacturer used the work to make 101 hires and expand by 65,000 square feet. SEO is delivered inside lead generation, website strategy, sales enablement and HubSpot implementation.
Weidert is the right fit for an established Midwest manufacturer that already runs or plans to run HubSpot and wants marketing and sales built as one system.
4. protocol 80 — Rural Pennsylvania HubSpot Diamond Shop That Writes Where Others Fear To Tread
protocol 80 was founded in 2002 by Donny Kemick and two classmates while they were still at college, and it still operates from Lewis Run, a village of a few hundred people in northern Pennsylvania. That location is not incidental. The agency’s clients are Rust Belt manufacturers selling to engineers and procurement professionals, and its stated specialism is niche content creation for technical subjects most agencies avoid, summed up on its site as building and writing where other agencies fear to tread.
The numbers are striking even allowing for small starting bases. Weber Knapp increased web leads 800 percent, McHone grew traffic 2,809 percent, Horizon Technology went from 40 to 15,000 monthly views, and Dahlstrom Roll Form, a 122-year-old roll-forming manufacturer, multiplied architectural product sales tenfold. protocol 80 holds HubSpot Diamond partner status and pairs SEO with paid search, LinkedIn advertising, HubSpot integrations, RevOps and trade show marketing, for which it publishes a dedicated manufacturer guide.
Shortlist protocol 80 if your products are technical enough that finding a writer who understands them has been the bottleneck.
5. TopSpot Internet Marketing — 150 People In Houston, Google Premier Partner, A 1,500 Percent Lead Lift On Record
TopSpot has run from Houston since 2003 and has grown to more than 150 team members, 900 clients and 800 launched websites, with industrial work as its core vertical. Its industrial practice targets suppliers and distributors, manufacturers, OEMs and service providers across aerospace, petrochemical, machining, plastics, fabrication, die cutting, wastewater, automation, steel processing and 3D printing, and the agency is listed in The Fabricator’s supplier directory.
The Mitchell Crane case study is the one to read: online lead forms rose from 9 to 144 a month, a 1,500 percent increase, with organic traffic up 187 percent within five months of a new site. Other named industrial clients include Blaylock Gasket, Rol-Tec, Steel Warehouse and Stainless Steel Products. TopSpot is a Google Premier Partner, a Google Analytics Certified Partner and a Bing Select Partner, and it runs dedicated industrial SEO and industrial PPC service lines alongside web design, conversion optimization and email. It now operates as an OuterBox company.
TopSpot suits a supplier or distributor that wants organic and paid search managed together by a large, process-driven team with a deep industrial bench.
6. Thomas — The Thomasnet Agency, Staffed By Degreed Engineers, Now Part Of Xometry
Thomas traces its lineage to the Thomas Register of 1898 and has operated an in-house digital marketing agency for industrial suppliers alongside the Thomasnet.com supplier platform for years. Since late 2021 it has been part of Xometry, the on-demand manufacturing marketplace. The agency describes itself as the industrial digital marketing services agency trusted most by manufacturers, industrial suppliers and distributors, and its team is supported by degreed engineers, which shows in the content it produces.
Thomas reports having helped more than 700 manufacturing and industrial companies improve their rankings. The Enerquip case study documents organic clicks up 38.5 percent year on year, users more than doubled and ranked keywords up 28 percent since 2021, with organic search now driving around half of the thermal processing manufacturer’s traffic. Services span SEO, content, PPC, video, email automation, CRM setup and website design, and the agency holds HubSpot Diamond and Google Certified Partner status. Its Thomas Industry Update newsletter reaches more than 300,000 subscribers, a distribution channel no competitor can match.
Thomas is the natural choice for a supplier already listed on Thomasnet that wants search, content and platform visibility handled by one team, and it publishes entry-level manufacturing SEO services packages from a few hundred dollars a month.
7. Lform Design — Web Design And SEO Exclusively For Manufacturers, Entirely In-House
Lform Design is a Montclair, New Jersey, agency with a satellite office in New York that has focused on manufacturers only since the mid-2000s and describes itself as a web design, development and SEO agency exclusively for manufacturing companies. Everything is delivered by a 100 percent in-house team under owner and creative director Ian Loew, with no subcontracted development or offshore content.
The agency’s strength is the site itself as an SEO asset. Work for IGI, a wax manufacturer, and AEE, a metal powder distributor, paired SEO-optimized rebuilds with ecommerce and live inventory integration, and Lform maintains technology partnerships with AWS, Salesforce, HubSpot, Shopify, SAP, NetSuite and BigCommerce for the integrations manufacturers actually need. It has added answer engine optimization for AI search and link building to the core service, and its FAQ sets a realistic expectation of early movement within three to six months from focused fixes. Lform publishes fewer hard numbers than others on this list, which is worth asking about in a pitch.
Lform fits a manufacturer whose website is the problem and who wants a specialist to rebuild and rank it without a handoff between design and SEO.
8. Marketing Metrics Corp — Twenty Years Manufacturing-Only, And A Client Grown From 4 To 24 Million Dollars
Marketing Metrics Corp has been manufacturing-focused since 2006 from Pewaukee, Wisconsin, and its team claims more than 55 years of combined experience working inside the sector. It serves more than 60 manufacturing companies nationwide, with a concentration in aerospace fasteners, robotics and automation, heat treating, metal stamping and OEMs, and it now frames its SEO offer around being visible when prospects search Google or ask ChatGPT.
Its flagship case study is unusual for its duration: Wisconsin Metal Parts grew from 4 million to 24 million dollars in revenue across a 17-year partnership. ACRO Automation landed a 60 million dollar customer order, an aerospace fastener manufacturer won the largest bid package in its history, and the agency quotes a 400 percent average lead increase across clients. Services run from web design and content to PPC, ecommerce, video and employment marketing for manufacturers struggling to hire. The agency is also openly critical of Thomasnet-built websites and publishes alternatives, which tells you something about its positioning.
Marketing Metrics suits a Midwest job shop or OEM that wants a long-term partner rather than a campaign, and one that can help with recruiting as well as leads.
9. OuterBox — A 250-Person Performance Agency With A Dedicated OEM And Distributor Practice
OuterBox is an Akron, Ohio, performance marketing agency founded in 2004 with further offices in Houston and Rochester, Minnesota, and more than 250 US-based in-house specialists. Industrial is one vertical among several, but it is a substantial one, with dedicated industrial SEO services aimed at helping OEMs, distributors and suppliers win more RFQs and qualified leads. The agency is a Google Premier Partner and Microsoft Advertising Select Partner and has appeared on the Inc. 5000.
The industrial case studies carry real figures. Rapid Rivets and Fasteners grew traffic 216 percent in six months with 155 percent more conversion events and 54 new business opportunities, Weiss-Aug Group shifted its traffic mix from 80 percent direct to 52 percent organic with two thirds of leads now coming from search, and Kapp Alloy and Wire lifted ecommerce sales 50 percent. OuterBox’s Shopify, BigCommerce and Adobe Commerce partnerships make it the strongest option here for catalog-heavy businesses with thousands of SKUs that need to be indexed and sold online.
Choose OuterBox if you are a distributor or OEM with a large online catalog and want SEO, paid media and ecommerce development from one large team.
10. Kula Partners — Halifax Manufacturing Specialists Behind The Kula Ring Podcast And The Industrial Buyer Pulse
Kula Partners has worked with B2B manufacturers and industrial brands from Halifax, Nova Scotia, since 2004, under principals Carman Pirie and Jeff White. It describes itself as a marketing agency built for B2B manufacturers, serving a global client base that includes ATS, Omron, Farnell, HMS, Westfalia, Abloy, Bridgestone, Daikin and Conquest Firespray, and it now integrates agentic AI into the work on every account.
Two things distinguish Kula. The Kula Ring podcast, made for manufacturing marketers by manufacturing marketers, has run to several hundred episodes and is the closest thing the sector has to a standing industry forum. And the quarterly Industrial Buyer Pulse report, launched in 2025 with a survey of 263 North American industrial buyers, gives the agency primary research on how engineers and procurement teams actually search and buy. SEO sits within a strategy, account-based marketing and web development practice, with HubSpot, Terminus and Google partner status. Kula publishes fewer numeric case studies than the US firms above, so ask for them directly.
Kula suits a manufacturer selling into a defined set of named accounts that wants search to work alongside ABM rather than in isolation.
11. Konstruct Digital — Calgary B2B Growth Agency With Sub-Sector SEO Pages From Fabrication To Mining
Konstruct Digital is a Calgary agency founded in 2012 and run by managing partners Matt Cox and Amanda Thomas, with a team of around 50. It positions itself as a revenue-focused B2B growth agency, and manufacturing and industrial companies make up the core of its client base, with oil and gas, mining and industrial IoT reflecting the Alberta market it grew up in. Its site carries dedicated pages for contract manufacturing, aerospace, electronics manufacturing, equipment, metal fabrication, food manufacturing and medical equipment.
Published results include a 147 percent increase in non-branded clicks for Proterial Cable America, a 485 percent rise in organic visibility for AbeTech, and a single campaign for Di-Corp that generated a million dollars in quoting activity. Other named clients include Wabash, Crane XOMOX, Chamco and InterClean. Konstruct runs B2B, enterprise, technical and international SEO alongside LinkedIn and Google advertising, content, web design and digital PR, and holds Google, HubSpot, Mailchimp and Semrush partner status. Retainers are tiered but not priced publicly.
Konstruct is a strong fit for a Canadian or northern US industrial company, particularly in energy-adjacent manufacturing, that wants SEO built around its specific sub-sector.
Marketing for Manufacturing does exactly what its name says, from Birmingham’s Jewellery Quarter, and has done since 2005. Its client base is rooted in the West Midlands engineering and metals economy, with Alloy Wire International, Brandauer, Strip Tinning, Impression Technologies, Storm Environmental, Arrow Solutions and Conveyor Units among more than 40 manufacturers on its site, and it works with UK and international firms alike.
The agency’s SEO offer, now branded as AI SEO to cover generative search, sits inside a service list built for how UK manufacturers actually market themselves: exhibition marketing, industrial photography, video, copywriting and PR, email, branding and LinkedIn lead generation alongside web design. The MWA Technology case study reports a 720 percent increase in online lead generation. With a team of around ten, it offers the direct access to senior people that larger agencies cannot.
Marketing for Manufacturing is the choice for a UK engineering or metals business that wants a specialist which understands trade shows as well as search.
How To Choose A Manufacturing SEO Agency
Is Manufacturing The Agency’s Business Or A Page On Its Website?
Almost every search firm now has an industrial landing page. Far fewer have industrial clients. Ask what share of revenue comes from manufacturers, whether anyone on the team has worked in a plant or holds an engineering degree, and for three case studies in businesses like yours with a reference you can phone. Gorilla 76, Lform, Marketing Metrics, Thomas, Kula and Marketing for Manufacturing work with manufacturers only. The others in this list run a substantial industrial practice inside a wider business, which is a legitimate model, but you should know which you are buying.
What Will The Agency Report On?
Traffic is close to meaningless for a manufacturer with a 50,000 dollar average order. The right measures are quote requests, qualified leads, pipeline and closed revenue attributed to organic search. The agencies above that publish results in those terms, Gorilla 76, Weidert, Marketing Metrics and Konstruct among them, are signalling that they expect to be judged on them. If an agency’s case studies are all keyword rankings and session counts, ask why.
Does The Agency Understand Your Buyer?
An engineer researching a supplier wants specifications, tolerances, materials, certifications, lead times and CAD files. A procurement manager wants capacity, capabilities and proof of quality systems. Neither wants a blog post about five trends in manufacturing. Look at the content an agency has produced for existing clients and judge whether a technical buyer would find it useful. Kula’s Industrial Buyer Pulse research and Thomas’s engineer-staffed content team are two answers to this question; protocol 80’s willingness to write about roll forming is a third.
Do You Need A Website Rebuild First?
Many manufacturer websites were built a decade ago as brochures and cannot support the product pages, structured data and technical resources that ranking now requires. If that describes yours, an industrial SEO agency that designs and develops in-house, such as Windmill, Lform, TopSpot or OuterBox, will get you further than a pure search shop that has to work around the site. Windmill’s published website pricing, starting around 40,000 dollars, is a reasonable benchmark for a serious industrial rebuild.
What About AI Search?
Engineers have taken to ChatGPT, Perplexity and Google’s AI Overviews quickly, because they ask precise questions and want direct answers. Being cited in those answers is becoming a separate discipline from ranking, and it rewards exactly the specification-rich, well-structured content manufacturers should be publishing anyway. Gorilla 76, Lform, Marketing Metrics, Marketing for Manufacturing and others have added AI search or answer engine optimization to their offer. Treat the label with some skepticism and ask what the work consists of, but an agency that has not considered it is behind.
How Should You Run The Shortlist?
Three agencies is the right number. Give each the same brief, covering what you make, who buys it, your average order value, your current site and analytics, and the outcome you need in twelve months, and ask for a case study in an adjacent sector rather than a general credentials deck. Then compare the questions they ask you. The agency that wants to see your quote log and talk to your best salesperson before proposing anything is usually the one that will produce leads rather than reports.
Conclusion
SEO for manufacturing companies rewards specialists, because the buyer, the vocabulary and the economics are unlike anything a generalist agency deals with day to day. The twelve manufacturing SEO agencies above have each earned their place through published results in industrial businesses, whether that is Gorilla 76’s pipeline figures, Weidert’s revenue attribution, TopSpot’s lead volumes or Marketing Metrics’ seventeen-year client relationships. Decide first whether you need a pure-play boutique or a large agency with an industrial practice, insist on reporting in quote requests and revenue, and choose the team that understands your engineer before it understands your keywords.
