Most B2B SaaS homepages look fine and sell nothing. The design is clean. The copy reads well internally. But visitors bounce, pipeline stalls, and nobody can explain why. The problem isn't design. It's messaging — and most teams don't have a structured way to diagnose it. SignalScore fixes that. It evaluates your homepage across 8 dimensions grounded in behavioral psychology and conversion research: - The 5-Second Verdict (Value Proposition Clarity) — Can a stranger get what you do in 5 seconds? - The Story Arc (Message Hierarchy & Flow) — Does the page tell a coherent story? - The Mirror Test (Customer-Centricity) — Is the page about the buyer, or about you? - The Status Quo Tax (Stakes & Cost of Inaction) — Does doing nothing feel expensive? - The Safety Net (Risk Reduction & Confidence) — Are purchase barriers removed? - The Proof Stack (Credibility & Social Proof) — Are the receipts real and in the right places? - The Logo Test (Competitive Differentiation) — Remove the logo — could this be anyone? - The Close (Conversion Architecture) — Does the page close, or just inform? You submit your homepage URL. Within minutes, you get a 0-100 score broken down by dimension, with color-coded benchmarks showing exactly where your page is strong and where it's failing buyers. The methodology draws on Kahneman and Tversky's Prospect Theory, Cialdini's principles of persuasion, Clayton Christensen's Jobs-to-Be-Done framework, and Gartner/CEB's B2B buyer journey research. This isn't opinion-based — it's a structured, research-backed diagnostic. The free tier gives you the full scorecard. The GTM Effectiveness Analysis ($299) adds detailed findings, research citations, and 3 prioritized recommendations. The Competitive Intel Report ($749) scores up to 3 competitors side-by-side and identifies open lanes in your market.
