North Fox
Senior engineering, measured

We make websites fast, findable, and cited by AI. Every result proven with numbers.

North Fox fixes the root cause in the code, not the symptom in a plugin. Performance, technical SEO, and AI search visibility for businesses that want the number to move, and want to see it move.

What we do

Three things, each with a number attached

Speed and Core Web Vitals

WordPress and Webflow sites optimized to pass Core Web Vitals on field data and not lab guesses. This includes generating critical CSS, asset unloading, image pipelines, and fixing the theme and plugin choices causing the problem in the first place.

Technical SEO

Fixing what stops search engines and AI systems from crawling, rendering, indexing, and interpreting your content. We migrate and rebuild without costing you rankings: a redirect for every old URL, each one verified after launch and not sampled, every Search Console error closed.

AI search visibility

We help your brand get cited when people ask ChatGPT, Perplexity, Gemini, and Google AI Overviews. We measure every result using Rankioz, which tracks which answers mention you and who gets mentioned instead.

When the fix is a system rather than a page, we build that too. We bring in senior engineers and architects to plan and build it, and every line is reviewed before it ships.

He took ownership of the project, walked me through factors I didn't know to consider. I worried about the process and ensuring my work, posts, links, SEO, etc, were maintained. I needed the slow, sluggish speed fixed, and now it works like a racehorse. I highly recommend him.

How we work

Measure first, then move

For every engagement, we start with a baseline from real field data like medians and percentiles instead of a single lab run. Once we diagnose the problem, we fix the cause, verify against the same measurement set, and report the difference. If a number didn't move, you'll see that too.

We won't promise you a #1 ranking. Nobody can guarantee rankings or scores, and an honest engineer won't pretend otherwise. What we do promise is that the work is measured, and that the measurement is one you can check yourself.

Who does the work

One senior engineer fronts every engagement

Nemanja Tanaskovic has spent more than ten years in production engineering across WordPress, Python and the web, and co-founded Rankioz, the AI visibility platform we measure with. He runs the meetings, writes the plan, and reviews every line that ships.

5,200+ hours and 38+ completed jobs on Upwork, Top Rated Plus, every review a 5.0.

What stood out just as much as the numbers is his honesty: he tells you what actually moves the needle versus what's just chasing a lab score, and flags trade-offs upfront instead of overselling.
