About SEO ESP

About SEO ESP

I started SEO ESP because I was tired of seeing businesses waste money on SEO strategies that don’t work. After more than a decade in the industry, working with companies ranging from startups to Fortune 100 brands, I’ve seen firsthand how often SEO is overcomplicated, oversold, and under-delivered.
That’s not how I work.
I built this consultancy on a simple idea: SEO should be clear, strategic, and tailored to your business, not a black box you’re forced to trust blindly.

Real Experience. Real Strategy

I’ve led SEO strategies for sites with millions of pages, worked on national directories, optimized complex eCommerce catalogs, and driven organic growth across both Google and Amazon. From content to technical SEO, I’ve managed it all—at scale and under pressure.

SEO That Scales Across Markets and Industries.

Over the years, I've worked across nearly every corner of SEO—from highly localized campaigns to international strategies spanning continents. That range gives me the perspective to know what works, what doesn't, and how to adapt based on your industry, market, and audience.

I've led strategies for both B2B and B2C brands, helping each reach the right people at the right time—whether it's a complex sales funnel or a high-intent product search.

Here’s a look at the breadth of my work

I’ve worked extensively in industries where competition is high and SEO is critical for growth, including: legal, travel, automotive, online directories, forum sites, employment & staffing, online retail & consumer goods, real estate, B2B consulting, home improvement and building, and many more.

No matter the vertical or scope, I bring a seasoned, strategic lens to every project—with a focus on clarity, performance, and growth that lasts.

Local & National SEO

Campaigns that build authority in a single city—or across the entire U.S.—depending on your business goals.

Enterprise SEO

Large-scale strategies for organizations with millions of pages and multiple stakeholders.

eCommerce SEO

Optimizing product catalogs, feed integrations, and marketplace listings to increase visibility and drive conversions.

What Sets SEO ESP Apart?

This isn’t an agency churning out audits you don’t understand. I use trusted tools, yes—but the value is in knowing which issues matter and which ones can wait. I filter out the noise and help you focus on the changes that drive real results.

I’ll never push a checklist just because a tool said so.
I won’t sell you on rankings that don’t convert.
And I’ll always explain why I recommend something—so you’re empowered, not dependent.

Who I Work With

I partner with brands that are ready for clarity and long-term growth. If you’ve been burned by bloated retainers or vague strategies—or you just want to understand SEO without the jargon—I’m here for that.

Whether you're an in-house team that needs a senior strategist or a founder trying to understand why traffic has stalled, we can work together to fix what matters and build what lasts.
