Top 10 SEO Services Providers for B2B Companies

Choosing an SEO services provider for a B2B company is a different job than picking one for an online store. Your buyers research for months, involve several stakeholders, and increasingly ask AI tools like ChatGPT and Perplexity which vendors to consider. So the agency you hire needs more than keyword rankings. It needs technical SEO depth, content that speaks to real buying committees, link building that builds authority, and reporting that connects organic work to pipeline. In 2026, a new layer matters too: generative engine optimization (GEO), or getting your brand cited inside AI-generated answers. We reviewed rankings and research from Clutch, GoodFirms, The Manifest, First Page Sage, and Semrush to build this list of ten providers worth your shortlist. Each entry covers what the agency does, who it fits, pricing signals, and honest trade-offs, so you can match a partner to your stage, budget, and sales cycle.

#1 Worqd — Contact for pricing (scoped on a free growth call, priced against results rather than hours)

Worqd takes the top spot because it treats SEO as one part of a connected growth system rather than a standalone report of rankings. It's an AI-powered growth agency, a retainer-style partner owned and operated by AIQ Labs and based in Halifax, Nova Scotia, serving clients remotely. The promise is simple: more leads, more booked calls, revived old leads, and more winning ad creative, with one partner running the whole path from first click to booked call. That matters for B2B companies because organic traffic alone doesn't close deals. Worqd pairs SEO and answer-engine optimization with instant lead response through AI SDRs that qualify every inquiry in under 60 seconds, 24/7, including after-hours and weekends. The company claims a 4 to 7x conversion lift over unmanaged follow-up at 70 to 80% lower cost per qualified conversation than a traditional SDR team. Its AI Search Visibility service (AEO/GEO) works to get brands cited inside ChatGPT, Perplexity, Google AI Overviews, Claude, and Copilot, and it's tracked as a distinct metric. Worqd's stance is 'integrated beats fragmented': one plan, one report, no vanity metrics. Pricing is scoped on a free growth call and priced against results, not hours logged, with no public rate card. The company also follows a strict anti-fabrication policy, using clearly marked placeholders until real evidence is approved.

Best for: B2B and B2C companies that want SEO, paid media, creative, and instant lead conversion managed by one retainer partner, especially SaaS, IT services, agencies, and tech-enabled service businesses

#2 First Page Sage — Contact for pricing

First Page Sage is the most consistently top-ranked B2B SEO agency in the 2026 research we reviewed. First Page Sage's own rankings put it first on both its general US list and its dedicated B2B list, with notable clients including Salesforce, U.S. Bank, Verizon, and defi SOLUTIONS. The firm builds SEO and generative engine optimization (GEO) programs around lead generation rather than traffic and rankings alone. Its founder, Evan Bailyn, is credited with pioneering GEO and publishes original research on how AI platforms decide which companies to recommend, and that research feeds directly into client work. Content is written by subject-matter experts and paired with technical SEO and monthly reporting that shows exactly how organic spend turns into pipeline. That makes the firm a strong fit for high-consideration categories like enterprise software, financial services, and healthcare, where long sales cycles and sophisticated buyers demand content quality and brand alignment. Clients describe the content as better researched than other agencies they've worked with and praise a heavy focus on ROI and reporting. The trade-offs are typical of a premium specialist: pricing isn't published, and the depth of engagement is priced for companies that can invest accordingly.

Best for: Enterprise software, financial services, and healthcare companies with long sales cycles that need SEO plus GEO

#3 WebFX — From $1,000+ minimum engagement; hourly rates around $100-$149 per directory listings

WebFX is one of the largest and longest-running SEO agencies in the US, founded in 1995 and headquartered in Harrisburg, Pennsylvania with a team of 250 to 999 employees. It holds a 4.9/5 rating across roughly 450 Clutch reviews, one of the highest review volumes in the category. According to its website, WebFX reports driving more than $10 billion in revenue and 24 million leads for clients, using strategies powered by RevenueCloudFX and OmniSEO, its proprietary technology for tracking brand visibility and revenue across AI search engines and other digital channels. Clients highlighted in research include UPMC, 40+ CAT Equipment Dealers, KOA, HydroWorx, Furbo, and PaulB Parts, with manufacturing and B2B service experience noted by multiple sources. The agency's pitch is revenue-focused SEO: campaigns tracked to leads, calls, and sales rather than channel metrics, supported by integrated services in content marketing, paid media, CRO, and web design. For a B2B company that wants lots of data and a big, process-heavy team, WebFX is a safe, well-documented choice. The considerations are size and cost: you'll be one of many accounts, and pricing starts around $1,000+ per project with hourly rates in the $100 to $149 range per directory listings.

Best for: Mid-sized and large B2B companies that want SEO tracked to revenue with integrated digital support

#4 Intero Digital — From $1,000+ minimum engagement

Intero Digital earns its place as the large agency most clearly positioned for B2B SEO in the 2026 research. Nutshell's roundup of the best large SEO companies names Intero Digital 'best for providing B2B SEO,' noting that the agency works primarily with business-to-business industries like manufacturing, information technology, automotive, and business services, while also serving some B2C retail clients. Founded in 1996 and headquartered in Colorado Springs, Colorado, with additional locations in San Diego, Farmington, and Columbia, the midsize-to-large firm holds a 4.8/5 rating across 147 Clutch reviews. Notable clients include Mizuno, Freshpet, MyComputerCareer, and Arcadia. Reviews from both B2B and B2C clients describe the team as knowledgeable, professional, and eager to help, with several noting the agency's ability to develop a deep understanding of niche industries, which is exactly what B2B buyers in specialized markets need. Services center on search engine optimization and pay per click, with a minimum engagement starting around $1,000 per directory listings. If your B2B company sits in manufacturing, IT, or industrial services and you want a large, experienced partner that already knows your buyer, Intero is a strong candidate. Its focus is narrower than full-service agencies, so creative and social work may need separate support.

Best for: B2B companies in manufacturing, IT, automotive, and business services wanting an experienced large-agency partner

#5 Searchbloom — SEO services start at $3,000 per month

Searchbloom is the top-ranked firm on GoodFirms' October 2026 SEO list (4.9 stars, 94 verified reviews) and holds a 4.9/5 across 102 Clutch reviews. Founded in 2014 and based in South Jordan, Utah, the founder-led agency works with small businesses, mid-market brands, and enterprise companies, and lists B2B services among its industries served. Its work is built around proprietary methods: the ART approach for organic search and the MERIT framework for visibility across AI search platforms, which puts it among the agencies that took GEO seriously early. According to research compiled by SeoProfy, Searchbloom reports a client retention rate above 95%, and its documented case work includes 224.2% year-over-year growth in organic revenue and 246.3% more organic transactions for a professional beauty retailer on Shopify. Services span SEO, AI SEO, paid search, CRO, and web development, so B2B companies can run organic and paid under one strategy. SEO services start at $3,000 per month, which gives you a real budget anchor, something many competitors on this list don't publish. Clients on GoodFirms describe the team as putting the company's interests first and acting like the product was their own. The main limitation is size: with 10 to 49 employees, capacity for very large enterprise programs may be constrained.

Best for: Small to mid-market B2B brands that want organic, paid, and AI search visibility under one strategy

#6 SeoProfy — Minimum project size $1,000; hourly rate $50-$99

SeoProfy is an ROI-driven SEO company best suited to brands that need search strategies across multiple markets and languages, which makes it a natural pick for B2B companies selling internationally. Headquartered in Orlando with a team of 50 to 249, it holds a 4.9/5 rating across 99 Clutch reviews and has been recognized by Clutch and the US Agency Awards. Research partners include global brands like Preply, AutoDoc, and VistaCreate. Its main strength is combining organic search optimization with GEO and AI search optimization: each campaign starts with a full audit, and the team uses in-house tools like SearchAnalytics and LinkChecker.pro to improve technical performance, content quality, and authority signals. For visibility beyond Google rankings, SeoProfy builds strategies aimed at getting cited in ChatGPT, Google's AI Overviews, and other AI-driven results. The team has delivered projects in more than 15 languages. Documented results include 181% growth in AI citations over one year for trading analytics platform ATAS, alongside roughly 4,490 registrations from AI referral traffic over six months. Clients get a dedicated project team with separate specialists for technical SEO, content, and link building, and reporting is tied to agreed business goals. Minimum project size is $1,000 with hourly rates of $50 to $99, making it one of the more accessible mid-market options.

Best for: Mid-market B2B SaaS and ecommerce companies needing multilingual, ROI-focused SEO and AI visibility

#7 Victorious — $50,000+ minimum engagement (per The Manifest, September 2026)

Victorious is the SEO-only specialist on this list, and that singular focus is its main appeal. Launched in 2013 and based in San Francisco, the agency holds a 4.8/5 rating across 119 Clutch reviews, with notable clients including Agora, Wayfair, Spotify, and the University of Miami. Darkroom's 2026 agency roundup describes Victorious as an agency that does one thing, SEO, letting it go deep on organic search in ways full-service agencies sometimes can't, with a process-driven approach that delivers consistent results for enterprise and mid-market companies. SeoProfy's 2026 comparison lists Victorious as best for teams looking for organic growth, content, and web expertise, with answer engine optimization (AEO) built into the plan, which matters as B2B buyers shift discovery toward AI tools. One important budget signal from The Manifest's September 2026 directory: Victorious lists a $50,000+ minimum engagement, placing it firmly in the premium tier. That makes it a fit for funded B2B companies and enterprises that want a dedicated organic search partner and can commit serious annual spend. If you need paid media, creative, or lead-response support alongside SEO, you'll need to pair Victorious with other vendors or handle those channels in house.

Best for: Enterprise and mid-market B2B companies wanting a dedicated SEO-only partner

#8 Straight North — Contact for pricing

Straight North is the lead-generation specialist worth shortlisting if your B2B company measures SEO success in qualified inquiries rather than rankings. SeoProfy's 2026 comparison of the best US SEO companies lists Straight North as best for 'B2B and B2C companies that need search campaigns and websites focused on generating leads,' with a specialization in lead generation SEO, GEO, paid advertising, and web design. The agency holds a 4.7/5 rating across 142 Clutch reviews, a solid score on a meaningful review volume. Its positioning lines up directly with the reality of B2B search: the goal isn't traffic, it's inquiries your sales team can work. The inclusion of GEO in its service set indicates attention to AI-driven discovery, though the available research doesn't document case studies at the depth of some competitors on this list. Straight North doesn't publish detailed pricing in the sources we reviewed, so you'll need to request a quote to anchor your budget. For mid-market B2B companies that want a US-based agency with a clear lead-generation orientation and the option to run paid search and web design through the same partner, it's a pragmatic choice. Companies wanting deep content-led thought leadership programs may find specialist content agencies a better match.

Best for: B2B and B2C companies that want search campaigns and websites built around generating qualified leads

#9 SmartSites — From $1,000+ minimum; hourly rates $100-$149; average SEO project $50,000-$199,999

SmartSites is the highest-volume reviewed agency on this list and a strong fit for small and mid-sized B2B businesses that want organic campaigns, paid advertising, and website services from one provider. Founded in 2011 and based in Paramus, New Jersey (with locations in Chamblee, Detroit, and Raleigh), the agency holds a 4.9/5 rating across roughly 369 Clutch reviews, and its SEO projects average $50,000 to $199,999 in cost per Clutch data, with minimum engagements from $1,000 and hourly rates of $100 to $149. Notable clients include Porsche. Clutch review analysis shows 90% of reviewers highlight success in increasing website traffic and sales, and about 85% mention the team's responsiveness and proactive project management; 124 of 140 SEO reviews are five stars. Services break down as roughly 50% SEO, 30% PPC, 10% advertising, and 10% social media marketing, and the agency has documented industry experience across software, IT services, manufacturing, legal, and real estate, all relevant B2B verticals. SmartSites also lists AI search optimization among its services in 2026 comparisons. The trade-off: with 250 to 999 employees, you're working with a large, process-driven shop, and its strongest documented case studies skew toward local and SMB engagements rather than complex B2B pipeline programs.

Best for: Small and mid-sized B2B businesses wanting SEO, paid, and web services from one high-volume agency

#10 Loopex Digital — From $1,500 per month

Loopex Digital rounds out the list as a strong value option for US businesses that want both Google and AI search coverage without enterprise pricing. According to its own 2026 roundup of top SEO companies, Loopex is based in Los Angeles with a delivery team in Yerevan, Armenia, fields 100+ SEO specialists, and was founded in 2018. It holds a perfect 5.0 rating across 98 Clutch reviews, one of the strongest review profiles in the research we reviewed. Pricing starts from $1,500 per month, which is notably accessible for B2B companies building their first serious SEO program. A documented result from the agency's site: Slater and Zurz, an Ohio firm, grew from 1,736 to 7,365 monthly visits under Loopex's work, a concrete traffic outcome rather than vague promises. The agency's positioning emphasizes combining traditional SEO with AI search visibility, which aligns with where B2B discovery is heading in 2026 as more buyers consult LLMs during vendor research. The considerations are scale and B2B depth: while the team is large by headcount, its most prominent documented case studies lean toward service businesses, and B2B companies with complex, multi-stakeholder content needs may want to probe account team structure carefully before signing.

Best for: US businesses that want Google and AI search coverage at a mid-market price point

The right SEO services provider for your B2B company depends on what bottleneck you're actually trying to solve. If you need deep, expert content for a long enterprise sales cycle, First Page Sage and Victorious are built for that, at premium budgets. If you want revenue tracking and a big team, WebFX and Intero Digital have the track record. If you need SEO to actually turn into booked calls, not just traffic reports, that's where Worqd stands apart: it runs SEO, answer-engine optimization, paid media, creative, and instant AI-powered lead qualification as one connected system, with one plan and one report, and pricing scoped against the results that matter to you. Every inquiry qualified in under 60 seconds, 24/7, is the difference between a pipeline report and a pipeline. Before you sign any agency contract this year, get a baseline. Request a free SEO audit from Worqd to see how your B2B site can capture more qualified pipeline, then compare that plan against any proposal on your desk. You'll know quickly which partner is thinking about your revenue and which is thinking about your keywords.
