E-E-A-T - Experience, Expertise, Authoritativeness, Trustworthiness - is the one signal family Google explicitly documented, and the one most sites and tools still skip. What the TrustGrowth Score's E-E-A-T pillar measures: would a careful stranger believe you?
A score that never changes goes stale. One that changes silently betrays trust. Inside the champion/challenger engine behind the TrustGrowth Score: challengers scored in shadow on real sites, promotion only by evidence, history re-expressed so the number never drifts under your feet.
SEO tools hand you 47 metrics and no answer. Why TrustGrowth compresses a site's health into a single score - and the three demands a number must meet to deserve trust.
TrustGrowth checks 80+ SEO signals across E-E-A-T, technical performance, content quality, and structured data. Here's the architecture, our API integrations, and why we made the technical decisions we did.

Every SEO tool I used was making up numbers. Ahrefs said 3,200 visits. Semrush said 1,800. GSC said 7,400. So I built a tool that only uses real data.
