FAQs about the best SEO companies
Looking to learn more about finding, researching, and hiring one of the best SEO companies in the world? Check out our FAQ, which covers some of the most common questions businesses have about finding and hiring an SEO agency!
How did you build this list of the top SEO companies?
Great question! This list of the top SEO companies looked at several factors when vetting agencies, like:
- Deliverables: The best SEO firms provide clients everything they need to launch and manage a successful SEO strategy, like keyword research and regular reporting, with their SEO services. So, our list focused on agencies that offered a turnkey SEO solution.
- Success factors: Another distinctive factor between SEO companies is how they measure client success stories. Do they look only at rankings, or do they look at real-world business metrics, like leads and revenue? The best SEO agencies look at both, with an emphasis on real-world impact.
- Client results: You can’t become one of the top SEO agencies without driving results for your clients. Through case studies, the SEO providers on our list demonstrated their expertise in SEO and client service.
- Client satisfaction: When it comes to the best SEO firms, it doesn’t matter how good they are if they can’t provide exceptional customer service. That’s why our list also factored in client satisfaction. Did online reviews show businesses loved working with this agency?
Who is the best SEO company?
While there are plenty of reputable SEO companies out there, WebFX has the deliverables, reviews, and experience that make us the best.
We don’t say we’re the best for no reason. We’ve delivered 1,312,500 page 1 rankings for our clients on Google.

If you want a partner in SEO that will create personalized, revenue-driving campaigns, WebFX is the best SEO company for you.
What services do SEO agencies offer?
SEO companies offer a wide range of services. SEO services often include the following:
- Keyword and competitor research
- SEO strategy development
- Implementation
- Reporting results
Types of SEO services include local SEO, ecommerce SEO, and SEO audits. Some SEO agencies also offer other digital marketing services, such as content marketing, PPC, and social media marketing services.
How much do SEO services from these agencies cost?
Typically, search engine optimization services cost $500 – $7,500 per month.
Unfortunately, only a few of the agencies on our list of the best SEO companies publish their prices online — WebFX is one of them. That means, if you want to see an agency’s pricing, you’ll need to contact them, which isn’t convenient in the early stages of looking for an SEO firm.
As a reference, if you’re partnering with one of the best SEO companies in the world, expect to see prices higher than the industry average. This price difference is often due to the agency’s experience.
Keep in mind, though, factors related to your business, like your SEO needs, will shape your SEO costs.
Are the best SEO marketing companies worth the money?
The answer to this question is almost always yes.
The top SEO agencies are often worth their price tag. They are experts in the field, and some of them have 20+ years of experience in the SEO and digital marketing industry.
They’ve witnessed the SEO landscape evolve and weathered different ranking challenges. When you hire them, they bring in expertise and their years of experience creating strategies that bring results.
While you can do SEO yourself (which takes time), partnering with a top SEO agency offers time savings, consistent results, and better ROI. That said, it’s critical to choose a transparent agency that suits your needs and budget, and creates a custom strategy for your goals.
How do I choose the best SEO company for my business?
If you’re ready to hire an SEO agency, then you’ll find these seven tips helpful:
- Identify your goals. Do you want to increase your traffic, leads, or sales?
- Set a monthly SEO budget. Identify how much your business is willing to spend on SEO.
- Research potential SEO companies. Determine whether you want to work with an SEO agency in your area, country, or time zone.
- Review the agencies’ case studies and testimonials. Check out the agencies’ case studies and find out how they implement SEO strategies and solve their clients’ pain points.
- Read the agencies’ reviews. Their Google Business Profiles and reputable review sites like Clutch and G2 are excellent sources of verified reviews.
- Compile questions to ask. Prepare questions in advance like how and when they report results, and their list of deliverables.
- Watch out for common red flags. Typically, rogue SEO companies have the same tactics, such as overpromising quick results. They are also likely not transparent about their strategies and technologies.
