Founded in 2009 by Noah Lopata, the agency has earned a strong reputation for results and transparency.

What to Look for in a Denver SEO Company
Not all SEO companies are built the same. If you’re hiring someone to manage your visibility, leads, and bottom-line results, here’s what actually matters.
Clear Communication and Reporting
You can’t improve what you don’t understand.
The best SEO companies keep you in the loop with reports that are simple, accurate, and focused on the right metrics.
You should know what keywords are driving traffic, how your rankings are trending, and what actions were taken this month, not just get a vague PDF with graphs.
Look for agencies that offer live dashboards, regular check-ins, and straightforward updates. If you’re always chasing down answers, that’s a red flag.
Services Aligned With Your Goals
SEO isn’t one-size-fits-all.
A local roofing company needs a completely different strategy than a national e-commerce brand. Some agencies specialize in local map packs and service keywords, while others are built for enterprise technical SEO, product pages, or international expansion.
Before hiring, get specific. Ask: Do you specialize in businesses like mine? If the answer feels generic, keep looking.
Experience in Your Industry
SEO moves faster when your agency understands your space.
Whether you’re in healthcare, legal, real estate, or the SaaS industry, knowledge saves time. It reduces guesswork. It leads to smarter keyword research, better content, and more relevant backlinks.
You want an agency that knows your audience, your competitors, and the language your customers actually use.
No Long-Term Contracts Without Proven Results
Locking into a 12-month contract before seeing performance is risky.
Good SEO firms don’t need to trap clients with long-term deals. Instead, they prove their value with results and keep clients based on outcomes, not obligations.
Ask for flexible terms. If an agency delivers, you won’t want to leave. But if it’s not working, you should have the freedom to pivot.
Website Quality and Ability to Rank Themselves
If an agency can’t rank their own site, why trust them with yours?
Check their site speed. Look at their content. Search Google for terms like “Denver SEO company” or “SEO services in Denver” and see where they show up.
If they aren’t on page one, or if their site feels dated, that’s a red flag.
A strong SEO agency should be their own best case study.
Conclusion
Hiring an SEO company isn’t about flashy case studies or promises to “rank #1.” It’s about partnering with a team that listens, executes, and moves the needle where it counts: qualified traffic, real leads, and more sales.
The agencies on this list each bring something valuable to the table.
But if you want a partner that’s laser-focused on turning your website into a predictable lead source, Epidemic Marketing stands out.
We don’t just optimize pages. We build conversion-focused systems that turn rankings into revenue.
And we back every move with clear data, simple reporting, and strategies designed for long-term growth.
