On the science of the assessment itself: Validated assessments combine self-report items with rubric-scored responses, producing a percentile profile against a normed reference sample. The strongest instruments report internal consistency above . and test-retest reliability above . over multi-week intervals, with construct validity established against external behavioural and outcome measures rather than self-judgment alone. Boundary conditions: regulators, employers, and researchers carve Technical SEO Specialist along different boundaries. Regulatory definitions (EEOC, ICO, EU AI Act Annex III) are protective and broad; employer taxonomies are operational and narrow; academic constructs sit somewhere between. Findings reported under one boundary translate imperfectly onto another, and we annotate translations inline. A note on uncertainty: every effect size on this page sits inside a confidence interval, and most intervals are wider than the published headline implies. Treat percentage shifts as directional rather than precise. Where a finding originates in a single underpowered study, we annotate that explicitly; where it has been replicated, the annotation flags the replication count. Nothing on this page should be read as a forecast — historical effect sizes establish a prior, not a prediction, for Technical SEO Specialist/Web Performance (Core Web Vitals, Lighthouse). Worth knowing exists: parallel literatures on procurement-stage vendor diligence, ISO and NIST AI-management frameworks, EEOC and ICO guidance documents, and the rapidly growing case-law map around algorithmic-hiring litigation.
