Mark B Marquis & Co Overview
Web design, SEO, and digital marketing for businesses across Southern New Hampshire — Windham, Salem, Derry, Manchester, Nashua, and the towns in between. Twenty years of digital marketing experience and an Air Force veteran's habit of doing the job right; when you hire MBM & Co, you get Mark on the work, not a junior account team.
We build sites that actually convert, write copy that ranks, and run paid campaigns that earn back what they cost — usually all three for the same client, because they're the same problem under different names. Local owners hire us when they're tired of agencies that disappear after launch and want someone who'll still pick up the phone two years in.
Mark B Marquis & Co Story
Mark B Marquis, Owner
Your customers don't all live in your zip code. Your visibility shouldn't either. We may use some techie jargon, but simply put, we get you more customers.
For over 20 years, we've helped online businesses improve their digital operations and boost sales — driving 30-200% growth for more than 70 clients using platforms such as Magento, Shopify, and BigCommerce.
In 2011, we started Commerce Forge. For 15 years, companies turned to us when their sales stopped growing, their online reach stalled, or their technology investments failed to pay off. We focused on building lasting partnerships, helping businesses grow their revenue, and working as trusted advisors — not just an outside service provider.
In 2026, we closed Commerce Forge and launched something new.
603 Circle is a group of local business tools based on a simple idea: strong communities support strong businesses, and strong businesses make communities better. After seeing small businesses struggle to get noticed and dealing with systems that hold back local economies, we decided to move beyond just improving websites and start building better support systems.
Now, we’re building three connected platforms: SNHLocal.com (a free online Guide for local businesses), MarkBMarquis.com (affordable digital marketing and SEO services), and ReviewSNH.com (a local review platform coming soon). All are supported by AI tools designed for small businesses.
We still offer what we've always provided: strategy, practical solutions, honest advice, and real results — now with a larger mission to help communities thrive.
