The founder
Built by an engineer, for business owners
I'm Mario Russo. I've spent 15+ years as a full-stack engineer building high-performance web applications and SaaS platforms — most recently 20 months as CTO of a local-commerce platform, building the full stack from the ground up.
W3Mkt exists because I watched the way customers find businesses change faster than small businesses could react. People ask ChatGPT who to call. And the businesses getting recommended aren't the best ones — they're the readable ones. That felt fixable, and it felt like exactly the kind of problem an engineer should fix.
I don't just use AI tools. I build software that works with the same web standards, and I test what these systems actually read instead of repeating folklore. Crawlers, structured data, entity consistency: this is the layer I work in, so that when someone asks AI for the best in your trade and your town, you have the strongest possible case for being in the answer.
I run every diagnostic personally. If we work together, you work with me.
Background

Why W3Mkt is different
Engineering, not media buying
We don't sell ads or placement. We fix the evidence AI systems read. The work is concrete and inspectable — you can validate every piece of it yourself.
The site is the proof
This website is the reference implementation of what we sell. By our own score it passes four of five dimensions; Cited is still amber, and we say so. View source, check the structured data, read robots.txt.
Honest by design
Nobody can guarantee a spot in AI answers, and we never claim to. What we can show you is the work and the measurements: before and after, in a readout you keep.
