The Best 19 Colorado SEO Companies to Choose From

If you’re in the search for a solid SEO agency in Colorado, I’ve got you covered.

While you know SEO is a thing you should be focused on, finding the right SEO partner is an absolute PITA.

Luckily, Colorado has some pretty solid SEO agencies to choose from, each offering services for different industries. 

Some focus on local SEO, and others focus on B2B companies.

Some offer more than just SEO, too.

In this article, I’ll walk you through the best SEO agencies in Colorado and which ones are the best for each industry.

I tried to keep this list pretty diverse so it could cover multiple industries. 

Let’s jump in.

The Top Colorado SEO Agencies to Choose From in 2024

1. Taylor Scher Consulting, LLC (Best for B2B Tech Companies)

While I’m not technically an SEO agency, I’m more of an SEO consultant and fractional SEO.

I’ve worked with a few Colorado-based tech companies and helped them grow in this market and nationally. 

The thing about me is that my approach to SEO is always revenue-focused.

Every tactic we focus on will be dedicated to growing revenue, not vanity metrics like traffic and conversions.

At the start of each engagement, I’ll do a full audit of your website that lists all the tactics we can use to reach a desired revenue goal.

That audit will basically be the roadmap throughout the engagement.

My services include:

• SEO Consulting
• Fractional SEO
• SEO Audits
• Full SEO Management

The only thing here is that I primarily work with B2B tech companies, so if you’re a local service provider, you might be better off with the other guys.

2. Firestarter SEO

Firestarter SEO is a Denver-based SEO agency that works with businesses across Colorado. 

Firestarter SEO is an SEO agency, first and foremost.

They’re not a digital marketing agency that offers SEO; they’re a specialized SEO agency.

Even better is that most of their SEO clients are based in Denver and Colorado.

They’ve worked with companies like Denver Tax Advisors, DCI Mountain Insurance, and Colorado Outback Adventures.

Firestarter seems to primarily work with small Colorado-based businesses, too, so they’re a great choice if you’re looking for a local company that serves local clients.

It also helps that they're the first result that comes up when you search for a “Denver SEO Agency.”

That doesn’t just happen; they obviously know their stuff.

3. Intero Digital Marketing Agency

Intero Digital is a full-service digital marketing agency based in Colorado Springs that helps Colorado-based businesses turn leads into customers. 

With offices in places like Colorado Springs, Denver, and other U.S. locations, they offer SEO, SEM, and pay-per-click (PPC) campaigns. 

They also offer social media marketing too.  

However, the majority of their projects seem to be around SEO.

Intero Digital has worked with a few notable companies, including Updox, PubMatic, and AMD Global Medicine.

Their client portfolio seems to be a mix of B2B, local service, and global companies.

4. Epidemic Marketing

Epidemic Marketing is an SEO and digital marketing agency based in Denver.

They’ve been helping businesses grow through SEO since 2009.  

In addition to SEO, they offer a few other services, including web and graphic design, local search campaigns, social media marketing, logo design, and Facebook marketing. 

However, it looks like they primarily work with local service-based companies, so if you need local SEO, Epidemic is probably the best place to look.  

5. Boulder SEO Marketing

Boulder SEO Marketing (BSM) is a Boulder-based agency that helps small and mid-sized businesses increase traffic and generate leads through SEO.

They offer services that include SEO, social media marketing, strategic planning, marketing consulting, and content creation. 

BSM is frequently recognized as one of the best SEO agencies in the Boulder and Denver area.

If you’re unsure about their services, they can even offer you a free SEO audit to show what they could be working on.

Their founder, Chris, is also heavily involved in the SEO space. 

He offers free trainings on how you can train yourself to learn SEO.

Boulder SEO marketing also offers pricing information on their website if you want to learn more about their services.

6. Peaks Digital Marketing

Peaks Digital Marketing is a Denver-based digital marketing agency specializing in SEO and lead generation for the medical and financial industry. 

Obviously, since their name is based on Pikes Peak, their goal is to help businesses reach the peak of their “digital summit.”

Pretty solid, right? 

Peaks is a pretty specialized SEO agency, too. 

While others on this list might be more integrated, they’re primarily focused on SEO and SEM.

You can even find pricing information on their website for different SEO packages.

Peaks seem to mostly work with B2B brands with a client list that includes SmartPayables and Polaris.

7. Colorado Digital

Colorado Digital is a Denver-based web design and digital marketing agency offering a few different marketing services for Colorado-based businesses. 

While web design is their main service offering, they also provide a full list of digital marketing solutions that include SEO.

Their specialty is building custom websites and web-based applications using open-source technologies like CentOS 7, MySQL, Apache, Bootstrap, and jQuery.

If you’re not looking to get started with a full provider, they can also provide audits for each one of their service offerings, including SEO strategy.

Some of Colorado Digital’s notable clients include Boeing, Colorado Creative Industries, and HunterDouglas.

8. Clicta Digital Agency

Clicta Digital is a growth-driven digital marketing agency based in Denver.

Clicta seems to primarily work with small businesses in the Colorado area.

Since they’re a full-scale digital marketing agency, SEO isn’t the only service they provide.

They can help with:

• Content Marketing
• Digital PR
• Influencer Marketing
• Paid Ads
• Social Media
• Social Ads
• Website Design

If you’re unsure whether you want to work with them, you can start off with a free consultation to understand how they might be able to help you.

9 Volume Nine

Volume Nine is a marketing agency based in Denver that has been helping businesses boost sales and lead flow since 2007.

They offer SEO as their main service but can also do social, content creation, and web analytics.

They mostly work with companies across B2B and B2C industries.  

Their mission is to optimize organic channels that help build a solid lead pipeline for you.

You can also request different audits from them for either SEO, social, and/or content.

10. Jolly Web Consulting

Jolly Web Consulting is a custom website design agency based in Boulder. 

Their whole approach is creating websites from scratch that don’t include any templates.

Most of their projects only take about 4-10 weeks to complete.

During this process, they can make sure your website is properly optimized for SEO.

They can help with link building, content creation, and content optimization.

Their team mostly works with CMS platforms like Wix, Webflow, Kajabi, and Squarespace.

Some of their clients include Top Tier Canine, Choice City Physical Therapy, and Out There USA.

11. Mountain Top Web Design

Mountain Top is a web design agency based in Greenwood Village.

While their main focus is web design, they do offer SEO services along with new websites. 

They can help you with full-scale digital marketing, WordPress sites, and branding.

They work primarily with B2B brands, including Redpoint Solutions, Microtek, and Cypress Homes.

12. Evergreen Marketing

While it would make sense for Evergreen marketing to be based in Evergreen, they’re actually based in Colorado Springs.

Evergreen is a full-scale digital marketing agency that provides solutions like:

• Digital Marketing
• Graphic Design
• Web Design
• Branding 
• Consulting

SEO is a part of their digital marketing offers. 

They have a mix of portfolios between Colorado and national companies, including Mayo Clinic, Rock Mountain PACE, and ClubCorp.

13. Empathy First Media

Empathy First Media, based in Denver, is an agency that blends marketing with AI. 

In addition to SEO, they also offer:

• Business Consulting
• Lead Generation
• Data Analytics

While they have an office in Denver, they seem to be a more national company with offices spread out throughout the country.

They have a pretty impressive client list working with companies like Slack, Elementor, and CallRail.

So, I have to imagine they’re more focused on enterprise-sized companies rather than Colorado-based ones.

14. Blennd

Blennd is a Denver-based website design and digital marketing firm that helps build custom websites for local clients.

While they are more focused on web design and brand building, SEO is an added bonus they offer to their services.

Most of their client base seems to be a mix of Colorado-based and national, which includes the Colorado Department of Transportation, Colorado Trial Lawyers, and OrangeTheory Fitness

15. Nimble Gravity

Nimble Gravity is a Denver-based marketing agency that specializes in blending AI with SEO.

While they won’t generate all your copy with AI, they know how to blend their services with AI automation to help you get more with less.

Since they specialize in AI automation, they can help build these systems into your company, too.

They’ve worked with a few Colorado-based companies, including Tribute Technology, Earthranger, and PurposeBuilt

Rothbright is a data-powered digital marketing agency based in Denver.

Their primary focus is on helping businesses reduce acquisition costs while growing through SEO.

Word of Advice When Looking for an SEO Agency in Colorado

When you’re looking for an SEO agency in Colorado, I’d recommend looking at companies that have a track record of working with brands in the area.

Not to say there’s anything wrong with working with an SEO or digital marketing agency that serves national clients, but I’ve found it’s much easier to collaborate with brands when they’re near my area.

Finding the Best SEO Company in Colorado

Finding the best SEO agency in Colorado doesn’t have to be hard.

In fact, it’s pretty easy since most of the companies on this list are verified and have solid reviews.

So, while there may be some companies outside this list you’ll want to consider, these were the companies I’ve vetted personally that deliver high-quality work, and they’re actually based in Colorado, too.
