DIY-platform outcome data (leads / sales / conversions) — essentially nonexistent in independent literature

Claim: There is no DIY-platform-specific independent data on whether sites built on Wix / Squarespace / GoDaddy / Weebly produce measurable business outcomes (leads, calls, sales). General benchmarks (B2B website conversion median ~2.9%; service vs SaaS variance) exist but are not segmented by build method.

Source: Survey of the literature (gap).

Confidence: This is a documented gap, not a finding.

Why this matters for Candid: The most important gap in the brief. The claim "DIY builders work for SMBs" cannot be substantiated at the outcome level with current data; only at the "site stays up" level. When a client asks "does this work?" the honest answer requires stating which definition of "work" applies. See Three success definitions for DIY-builder sites — subscription active vs domain resolving vs content updated and R5 — Thresholds that would change the assessment — name the gaps so they can be filled.
