Dr Blaze
Blazej Mrozinski
Strategist, Psychometrician & No-BS Partner
the short version
A psychometrics PhD who treats your funnel like a measurement model.
Blaze is a PhD in social cognition and psychometrics, with 16+ years lecturing in stats, data science and psychology at top European universities, with degrees from SWPS and LSE.
He's co-founded and worked in multiple data and tech ventures, most notably Gyfted, where he led product psychometrics, assessment, data and UX for talent evaluation and user self-awareness, helping grow it to 1.2M organic users a year.
He brings a measurement-led, razor-sharp analytical approach to SEO: deep into the data and the technicals, crafting strategies that are both scalable and effective. A straight shooter who cuts through the fluff: no sugarcoating, no empty promises.
example of savagery: Lectures on psychology × stats × data science. Wrote computer viruses for fun in college. Deep into OSINT.

The Ten Blue Links Are Gone: We Dissected 30 SERPs
We dissected 30 SERPs: 0 were ten blue links; 97% had People Also Ask and video, 77% an AI Overview, 50% ads; ranking #1 no longer means top of the page.
Is the CTR-by-Position Curve Real? We Tested 1,000 Rankings
Top-3 roughly tracks the curve, but on ~1,000 real rankings positions 11-20 out-click 4-10 (15.6% vs 8.7%); the canonical CTR curve is a population artifact.
Is Keyword Difficulty Accurate? We Audited 30 SERPs
A validity test of Keyword Difficulty on 30 SERPs: KD tracks page-level links (ρ=0.91) but barely domain authority (ρ=0.36). Easy keywords were DR 72-94.
