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. Our SEO services provide turnkey solutions to on-page, off-page, and technical SEO, including a custom strategy, return on investment (ROI) reporting, AI insights, and more.

What is an SEO company?
SEO companies provide search engine optimization (SEO) services to help their clients rank well in relevant search results on search engines such as Google. The best SEO companies ensure that the SEO strategies they use align with their clients’ needs and goals and drive meaningful results for their businesses, such as leads, sales, and revenue.
What services do SEO agencies offer?
SEO companies offer a wide range of services. SEO services often include keyword and competitor research, developing an SEO strategy, implementing that strategy, and 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 services, PPC services, and social media marketing services.
How much do SEO services from these agencies cost?
Typically, search engine optimization services cost $2500 to $7500 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 hiring 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.
Price is a crucial factor when outsourcing your SEO. Many companies, however, use price to make (versus shape) their hiring decisions, which results in hiring a cheap SEO agency. These agencies typically advertise SEO services at less than $500 per month.
Working with a cheap SEO company impacts your:
- Client experience
- Return on investment
- SEO results
- And more
Not to mention, these agencies can also damage your reputation with Google — the world’s biggest search engine. If Google decides your website isn’t trustworthy because your agency practiced black-hat SEO, your business will continue to struggle to rank in search results, long after you’ve let the agency go.
This all-too-common scenario forces your company to spend additional dollars on undoing the cheap SEO firm’s damage. In the end, you spend more money than if you’d partnered with a reputable SEO agency that had higher (but more realistic) prices.
That’s why, yes, the top SEO agencies are often worth their price tag.
They provide you with the peace of mind that you’re working with a company that will grow your online visibility and help your business increase its revenue. So, remember to use multiple factors to make your hiring choice versus making price the deciding factor.

Is it worth it to hire an SEO company?
You’re looking into hiring an SEO company, but you might still be wondering — is it really the right choice? Can’t I just do SEO in-house?
Realistically, yes. You could do SEO in-house — but how much time do you have to spend on it? Have much knowledge and experience do you have with SEO?
SEO is something that requires time, experience, and expertise to do. If you’re missing one of these things, it’ll make it difficult to see success with your SEO strategy.
That’s why it’s worth it to hire an SEO company — SEO companies have time, expertise, and experience they can bring to your SEO campaigns.
