10 Best SEO Outsourcing Companies in The United States

Reading Time: 7 minutes

Outsourcing SEO can mean five very different things: hiring a full-service agency, buying white-label fulfillment for your own agency, bringing on a specialized contractor, or something in between. Picking the wrong model wastes more money than picking the wrong company.

Flying V Group builds SEO programs for businesses that want a managed partner, not just a vendor filling a checklist. Contact us to see what an outsourced SEO engagement could look like for your team.

1. Flying V Group

Flying V Group is a full-service digital marketing agency built around measurable outcomes rather than just rankings and reports.

Core Specialties

We manage SEO and GEO as an integrated discipline, since AI-driven search results now sit alongside traditional rankings. That work is paired with content marketing, PPC, and web design, so technical fixes, content, and paid acquisition are never managed in silos that contradict each other.

Every engagement starts with a technical and content audit before any recommendation gets made. We explain the reasoning behind each change in plain terms, not just a ranking report that arrives with no context attached.

Community and Track Record

Clients get visibility into what is actually being implemented, not a black box that only surfaces monthly metrics. We treat SEO outsourcing as a partnership where strategy and business context stay transparent throughout.

Businesses come to us because they want an outsourced team that behaves like an extension of their own, not a fulfillment desk working from a generic playbook. That distinction shapes how we scope, report, and communicate on every account.

2. OuterBox

OuterBox is an Akron, Ohio-based agency founded in 2004, with an in-house team of more than 250 people built around eCommerce SEO. Their case studies include a multi-year program for CORSA Performance that produced 366% organic search revenue growth over 24 months.

Businesses running Shopify, WooCommerce, or BigCommerce stores with large catalogs are the strongest fit here, since much of their published work centers on platform-specific technical and content strategy.

3. Fannit

Fannit is a Seattle-area agency founded in 2008, specializing in SEO, PPC, and content for home service contractors, manufacturing, and local service businesses. Clients on review platforms describe steady traffic growth for smaller, locally focused operations rather than enterprise-scale campaigns.

This makes Fannit a better match for owner-operated or regional businesses than for companies needing large-scale content production.

4. Manta

Manta has operated as a business directory and local SEO provider since 1997, focused on citation building, Google Business Profile optimization, and reputation management for small businesses. Its scope is narrower than a full SEO agency, concentrating on local visibility rather than competitive organic rankings.

Businesses that mainly need consistent local listings and review management, rather than a full content and link-building program, are the intended fit.

5. Sure Oak

Sure Oak is a boutique New York agency founded in 2017, recognized on the Inc. 5000 list and known for direct access to senior strategists rather than junior account teams. Published case studies include a reported 300% increase in organic traffic for a public speaking and media training company after a strategy pivot during the pandemic.

Their smaller team size suits companies wanting close collaboration over large-scale content production capacity.

6. SEO Discovery

SEO Discovery is a white-label SEO provider that has operated for more than a decade, built specifically for marketing agencies that want to resell SEO fulfillment under their own brand. Work is delivered without the agency’s name attached, so the reselling relationship stays invisible to the end client.

This model fits agencies needing SEO capacity without hiring or training an internal team, not businesses looking to hire a provider directly.

7. UpFire

UpFire, based in Stamford, Connecticut, positions itself around transparent reporting and avoiding the shortcuts common among lower-cost providers. Client reviews cite improved keyword rankings for businesses that previously had no first-page visibility, including a branding agency generating new leads through organic search.

Its smaller scale suits SMBs wanting direct account access over an agency with dozens of specialized departments.

8. The HOTH

The HOTH is a Florida-based white-label SEO reseller offering productized packages, from link building to full-service management, aimed at both individual businesses and agencies reselling under private label. Review sentiment is mixed: many reviewers cite strong results and responsive account management, while others report disappointment with pricing transparency and outcomes.

That split makes due diligence on account-manager quality and package scope especially important before committing.

9. SEO Inc.

SEO Inc. has operated since 1997, making it one of the longest-running SEO specialists in the country, with a client roster that includes Fiskars and Hallmark. The company positions itself around search as its core product rather than one service among many, with dedicated technical SEO and enterprise offerings.

Its long operating history and Google Premier Partner status make it a reasonable fit for businesses prioritizing longevity and enterprise-scale technical work.

10. SeoProfy

SeoProfy is a data-driven SEO agency with published case studies across SaaS, ecommerce, legal, and iGaming, including clients like Preply and Autodoc. Their case studies report specific, verifiable metrics, such as a SaaS client’s organic traffic growing from 22,000 to 68,000 monthly clicks.

Businesses in competitive, specialized verticals may find their proprietary reporting tools and industry-specific case studies useful for vetting fit before signing on.

How to Evaluate an SEO Outsourcing Company

Picking a provider by price and portfolio screenshots alone misses the questions that actually predict a good outcome. Google’s own guidance on hiring an SEO recommends asking prospective providers for audits, realistic estimates, and explanations of proposed changes before signing anything.

Google is also direct about one thing: no one can guarantee a specific ranking position. A provider promising a first-place spot on Google is making a claim Google itself says isn’t possible to guarantee.

Questions Worth Asking Before Signing

Before committing to any outsourcing model, ask providers to walk through their process rather than just their pricing tiers. Useful questions include:

  • Can you show examples of previous work and explain the reasoning behind changes made?
  • How do you measure success, and is that tied to rankings, traffic, or revenue?
  • What is your content quality-control process, and who actually writes it?
  • Where do backlinks come from, and can we review placements before they go live?
  • What account access do you need, and can it be scoped to only what’s necessary?

What to Outsource, and What to Keep In-House

SEO outsourcing does not have to be all-or-nothing. Keyword research, content briefs, and technical audits are highly outsourceable tasks that specialists handle well.

Strategy and client communication are harder to fully hand off, since they require deep familiarity with the business itself. Many agencies outsource fulfillment capacity while keeping strategy and client relationships internal, which is a very different arrangement than outsourcing the entire SEO function.

Why Content and Link Quality Carry Real Risk

Cheap, high-volume packages can create more risk than value. Google’s spam policies explicitly define scaled content abuse, which includes mass-producing low-value pages without added value, as a practice that can cause pages to rank lower or disappear from Search entirely.

The same policies address link spam, including buying links or using automated link creation specifically to manipulate rankings. A cheap link-building package that doesn’t disclose where links actually come from is worth scrutinizing closely before signing.

Outsourcing the Work Doesn’t Outsource the Risk

If an outsourced vendor’s tactics violate Google’s policies, the penalty lands on the client’s website, not the vendor’s. That risk should factor into vendor selection at least as heavily as price and turnaround time.

Account Access Deserves Its Own Conversation

Outsourcing SEO often means granting access to Google Search Console, GA4, a CMS, or hosting environments. Google’s own permissions documentation recommends granting Search Console users only the access level they actually need, rather than defaulting everyone to owner-level permissions.

Revisiting and removing access for vendors who no longer need it is a simple habit that most businesses skip until something goes wrong.

Don’t Take Reviews and Case Studies at Face Value

A 4.9-star rating with hundreds of reviews says less than it appears to. The FTC’s guidance on online reviews warns that solicited, incentivized, or selectively requested reviews can misrepresent how a company actually performs.

For case studies specifically, look for a named client, an identifiable starting point, and a defined timeframe rather than an isolated percentage with no context attached. That level of detail is a better signal than the review score sitting next to it.

Ready to Outsource SEO the Right Way?

Choosing an SEO outsourcing partner comes down to matching the provider’s actual model, whether managed service, white-label fulfillment, or specialist contractor, to what your business or agency genuinely needs. Flying V Group builds SEO programs with that transparency built in from the first audit. Get in touch to talk through what your outsourcing model should look like.

Frequently Asked Questions

What are the benefits of outsourcing SEO?

Outsourcing SEO gives a business access to specialized expertise, tools, and processes without the cost of hiring a full internal team. It also frees internal staff to focus on core operations while a dedicated provider handles technical audits, content, and ongoing optimization.

How much does it cost to outsource SEO?

Monthly retainers for outsourced SEO commonly range from $1,500 to $5,000 depending on scope and competitiveness, with white-label fulfillment packages sometimes starting lower. Project-based work, such as a one-time audit or migration, can range from $1,000 to $30,000 depending on site size and complexity.

What should I look for in an SEO outsourcing company?

Look for a provider that can explain its process, show verifiable case studies with real client names, and answer specific questions about content quality control and link sourcing. Avoid any provider promising a guaranteed ranking position, since Google itself states that no ranking can be guaranteed.

Is it better to outsource SEO or hire in-house?

Outsourcing is often more cost-effective and provides immediate access to specialized skills across technical SEO, content, and reporting. An in-house hire offers more day-to-day control and institutional knowledge, but is more expensive and limited to one person’s bandwidth.

What’s the difference between a white-label SEO provider and a full-service agency?

A white-label provider delivers SEO fulfillment under another agency’s brand, so the end client never sees the provider’s name. A full-service agency works directly with the client under its own name, typically offering more direct communication with the team doing the work.

How long does it take to see results from outsourced SEO?

Most outsourced SEO engagements show early movement in rankings and traffic within three to six months, with stronger compounding results building over six to twelve months. Timelines depend heavily on the site’s existing authority, competition in the industry, and how much technical cleanup is needed before growth work can begin.

What account access does an outsourced SEO provider actually need?

Access requirements vary by scope, but providers typically need at least restricted-level access to Google Search Console, GA4, and the CMS to do meaningful work. Businesses should grant the minimum access level required for the task and periodically review or revoke access for vendors no longer working on the account.
