Measure twice.Build once.

I'm Ivan Smiljkovic, an SEO engineer in Serbia. I measure how Google and AI assistants decide what to show, then build the sites, tools and automations that act on what I find.

Research

What I've measured

Studies of what ChatGPT and Google's AI Overviews cite, quote and recommend, run on real searches. Every number is computed from data I collected and checked twice.

What I do for clients

Most projects start with a measurement and end with something built, then measured again.

Measure

AI search and SEO audits

I run your real searches through Google, AI Overviews and ChatGPT, crawl your site, and show where you're cited, where you're missing and what's in the way.

  • Your searches tracked in Google and AI answers
  • A full crawl turned into a ranked fix list
  • The same measurement re-run after the fixes
Done before

Automated an agency's SEO audits: $1,000 saved per audit and no more one-week wait.

Build

Page sets, sites and migrations

Programmatic page sets, landing pages and site moves, built on real data and checked before launch.

  • Templates fed by your data, not filler
  • Schema, internal links and tracking set up
  • Every page crawled before it goes live
Done before

Launched about 800 pages for a law firm and moved its site from WordPress to Astro with no traffic loss.

Automate

Automations and internal tools

Tools your team uses every week: rank and AI-answer tracking, data collection, dashboards, reports and content checks.

  • A working tool your team can run
  • The code, with a written handover
  • Built on the same checks I use for my studies
Done before

Automation I built for one agency saves it $180,000 a year.

How I work

Measure, build, measure again.

You work with me directly, from the first number to the handover.

  1. Measure

    I start with where you stand: your site, your real searches in Google and AI answers, and the numbers you already track.

  2. Build

    Then I build the smallest thing that should move those numbers: pages, fixes, a tool or a pipeline.

  3. Measure again

    Then I re-run the same measurement and show you what changed, including what didn't.

Rule 1

Measured, not guessed.

Every number I give you comes from data I collected and can show you.

Rule 2

Checked twice.×2

Every number is computed two separate ways before it leaves my desk.

Rule 3

Bets are labelled.

Advice that hasn't been tested is marked as a bet, so you know what's proven and what isn't.

Work

Things I've built

My own sites, the pipeline behind my research, and open-source tools from my day-to-day work.

About

Hi, I'm Ivan.

I got into SEO in 2017 with a Pokémon Go fan site. It reached 15,000 visitors a day, and I sold it.

Since then I've run SEO and growth for two products, grown a network of 200+ sites to a peak of 10M+ monthly visits, and taken an AI app to 400,000 monthly organic visits.

Today I build SEO and AI-search systems for agencies, law firms and product companies, and I publish what I find.
