When businesses want to improve their online visibility, generate consistent organic traffic, and compete in search results, one of the most common terms they search for is SEO agency. But while the term sounds straightforward, choosing the right SEO partner is rarely simple.
There are thousands of SEO agencies worldwide. All offering similar promises, packages, and guarantees. Some genuinely help businesses grow, while others rely on generic strategies that rarely deliver long-term value.
This guide explains what an SEO agency is, what services it offers, how to choose the right one, and which agencies are commonly considered top in the U.S. market.
In the second part of this guide, I’ll also share real-world insights many businesses experience after working with agencies and why, in many cases, working directly with an individual SEO specialist can be a better alternative.
What Is an SEO Agency?
An SEO agency is a company that provides search engine optimization services to help websites rank higher on search engines like Google. These agencies usually manage multiple clients simultaneously and follow structured processes to improve visibility, traffic, and conversions.
Most SEO agencies operate with teams that include:
-
SEO strategists
-
Technical SEO specialists
-
Content teams
-
Link-building teams
-
Account managers
Their primary goal is to align a website with search engine algorithms while improving overall user experience.
What Services Do SEO Agencies Offer?
Most SEO agencies provide a combination of the following services:
Technical SEO
This focuses on improving the website’s foundation, including:
-
Site speed optimization
-
Crawlability and indexing
-
Fixing technical errors
-
Mobile optimization
-
Core Web Vitals improvements
On-Page SEO
On-page SEO includes:
-
Keyword research

Why Businesses Hire an SEO Agency?
Businesses usually hire SEO agencies because:
-
They want a team-based approach
-
They don’t have in-house SEO expertise
-
They prefer outsourcing long-term SEO work
-
They want structured reporting and tools
For larger organizations and enterprises, agencies can sometimes be a practical solution especially when scale and internal processes matter.
Types of SEO Agencies (Based on Business Needs)
Not all SEO agencies work the same way. Many specialize based on business models and goals.
Local SEO Agencies
Local SEO agencies focus on improving rankings for location-based searches, Google Maps, and local citations.
Ecommerce SEO Agencies
These agencies specialize in:
-
Product and category page optimization
-
Technical SEO for large online stores
-
Revenue-focused keyword strategies
B2B SEO Agencies
B2B SEO agencies focus on:
-
Long sales cycles
-
High-intent keywords
-
Lead quality rather than traffic volume
SEO Marketing Agencies
Some agencies combine SEO with broader digital marketing services such as PPC and CRO. While this can work for some businesses, SEO often becomes just one part of a larger package.
Is There a “Best SEO Agency”?
There is no universal best SEO agency. What works for one business may not work for another. Agencies that claim to be “best for everyone” often rely on standardized approaches.
Top SEO Agencies in the USA
When people search for “top SEO agency” or “best SEO agencies in the USA”, certain names consistently appear in industry lists. Below are commonly recognized agencies, shared here as examples, not endorsements.
1. WebFX
WebFX is widely known for its data-driven SEO approach and revenue-focused campaigns. The agency works with large teams and emphasizes analytics and performance tracking.
2. Thrive Internet Marketing Agency
Thrive is recognized for offering full-service digital marketing, including SEO, with flexible contracts and a strong focus on transparency.
3. Straight North
Straight North is often highlighted for its lead-generation focused SEO strategies and detailed reporting systems, particularly for B2B companies.
4. OuterBox
OuterBox specializes in ecommerce SEO, helping online stores improve rankings, traffic, and conversions through technical and content-driven strategies.
5. Victorious
Victorious is known for transparent SEO campaigns and clear performance tracking, often working with mid-to-large businesses.
These agencies are well-known because of their scale, marketing presence, and portfolio size but, that doesn’t automatically mean they’re the right fit for every business.
How to Choose the Right SEO Agency?
Choosing an SEO agency should never be based on price alone. Here are key factors to consider:
1. Transparency
A reliable SEO agency should clearly explain:
-
What work they will do
-
How success is measured
-
What tools they use
-
How often reports are shared
2. Custom Strategy
Avoid agencies offering identical SEO packages to every client. SEO strategies should be customized based on:
-
Industry
-
Competition
-
Business goals
-
Website condition
3. Communication Structure
Ask who will actually work on your site. Many agencies assign account managers instead of direct SEO specialists.
4. Case Studies & Proof
Case studies should show:
-
Real metrics
-
Timeframes
-
Clear progress indicators
5. Red Flags
Be cautious if an agency:
-
Guarantees #1 rankings
-
Avoids explaining their strategy
-
Pushes long-term contracts upfront
Hold On - Before Moving Forward: An Important Perspective
Before discussing common issues businesses face with SEO agencies, it’s important to clarify something.
This guide is intentionally structured into two clear blocks:
-
Block One: Understanding SEO agencies; how they work, what they offer, and how to choose one
-
Block Two: Real-world challenges, comparisons, and an alternative approach many businesses don’t consider initially
If you’ve ever wondered why two businesses with similar goals get very different results from SEO agencies, the next section will likely explain why.
Common Problems Businesses Face with SEO Agencies
Based on real experience, many businesses encounter similar challenges after hiring an SEO agency.
High Costs & Long Retainers
SEO agencies often charge high monthly retainers to cover overhead costs such as staff, tools, and management.
Generic SEO Strategies
Many agencies reuse the same SEO frameworks across clients, regardless of niche, competition, or goals.
Lack of Direct Communication
Clients usually communicate with account managers instead of the SEO expert doing the actual work.
Slow Execution
Internal processes and approval layers can delay even simple updates.
Hidden Charges
Some agencies charge extra for content updates, technical fixes, or additional reports.

When Working with an Individual SEO Makes More Sense?
Working directly with an SEO expert is often a better choice for:
-
Small and medium businesses
-
Local service providers
-
Startups
-
Businesses needing flexibility
-
Owners who want transparency
Instead of being one client among many, you get direct involvement from the person handling your SEO.
