Reference framework: which website dimensions decay vs compound over 10 years (12-dimension matrix)
Created 2026-05-22
The 12 dimensions of a website over a 10-year horizon — which decay without intervention, which compound on the right foundation.
| Dimension | Default (no foundation) | With foundation-first | Why |
|---|---|---|---|
| Visual design | Decays — dated in ~3yr | Decays slower with minimal semantic style | Trends move; restraint ages better |
| Long-form content | Decays — link rot, stale facts | Compounds via refresh + structured-data updates | HubSpot (Pamela Vaughan): historical-optimization refresh of old posts lifts organic traffic by avg 106% |
| Code dependencies | Decays — plugins abandoned | Compounds — fewer deps = less surface | Patchstack 2024: 4,166 new vulnerabilities, 96% in plugins, 4% in themes, only 7 in core |
| Hosting | Decays — provider EOL, acquisitions | Stable on commodity Linux + portable code | Squarespace acquired Google Domains for $180M (Sept 7, 2023) — ~10M SMB domains migrated automatically |
| Structured data | Neutral | Compounds — AI citations, GEO | Research brief: Structured content as a competitive advantage (piece 2 of 15) |
| SEO authority | Decays without URL discipline | Compounds heavily | [[sej-892-migrations-523-day-recovery]] |
| Domain age | Compounds — trust signals accrue | Compounds | One of the few unambiguously time-positive ranking inputs |
| Citation graph | Decays with link rot | Compounds with URL preservation | Zittrain et al. (Harvard Law 2014): 50% of URLs in U.S. Supreme Court opinions suffer reference rot |
| Security posture | Decays rapidly without patching | Stable with continuous patching | Sucuri 2023: 39.1% of CMS apps outdated at point of infection (down from 50.58% in 2022) |
| Accessibility | Decays — WCAG advances, EAA in force | Stable with semantic HTML + CI testing | UsableNet 2025: 5,000+ digital accessibility lawsuits filed; 46% of federal cases involve repeat defendants |
| Performance / CWV | Decays — page weight grows, scripts pile up | Stable with CI-enforced budget | Web Almanac 2024: median desktop page weight — WordPress 2,252 KB, Wix 2,560, Squarespace 3,323; 90th pct crosses 8 MB |
| Brand equity | Decays if site quality drops below brand promise | Compounds when site quality matches brand | Trust accumulates against consistent presentation |
| Internal docs/KB | Decays as staff turn over | Compounds when stored in repo + KB | Research brief: The knowledge-base-backed website (piece 3 of 15) |
Net argument: Roughly half of these dimensions can compound — but only on architecture that lets them. On a brittle stack, every dimension decays simultaneously.
