Website Valuation Tool - Changelog ================================== Version 1.3.0 - Valuation Logic Refinements (March 12, 2026) ------------------------------------------------------------- FIXES: - Website Type now affects asset-based valuation via a type multiplier (SaaS/Web App 1.40x down to Agency/Service Site 0.85x) - Revenue Proof Available checkbox is now disabled/greyed out when Monthly Revenue is blank or £0 - Selecting one monetisation method no longer penalises the valuation; zero and one methods are both neutral, 2+ methods give increasing bonuses - Included Assets no longer appear to decrease valuation when checked LOGIC CHANGES: - Email Subscriber Count only affects valuation when "Email List" is ticked in Included Assets (if you are not selling the list, its size cannot increase the sale price) - Social / Community Audience Size only affects valuation when "Social Accounts" is ticked in Included Assets - Entering an Email Subscriber or Social Audience count > 0 now auto-ticks the corresponding Included Asset checkbox - Email List and Social Accounts no longer receive the flat £500 per-asset bonus (their value comes from subscriber/audience counts instead) - Social Accounts with 0 audience receive a small £200 base value when included (branded pages have some inherent value) - All insights and summary text now respect the included assets condition MONETISATION SCALE (multiple adjustment): - 0 methods: 0 (baseline) - 1 method: 0 (neutral) - 2 methods: +1 - 3 methods: +2 - 4+ methods: +3 WEBSITE TYPE MULTIPLIER (asset-based): - SaaS/Web App: 1.40x - Membership Site: 1.25x - Directory/Marketplace: 1.20x - Lead Generation: 1.15x - Tool/Calculator: 1.10x - Affiliate Site: 1.05x - Content/Blog: 1.00x (baseline) - eCommerce: 0.95x - Other: 0.90x - Agency/Service Site: 0.85x ================================== Version 1.2.0 - Calculation Accuracy Fixes (March 12, 2026) ------------------------------------------------------------ FIXES: - SEO/Backlink Strength: Traffic-quality multipliers (SEO, source, concentration) now only apply when monthly visitors > 0, preventing phantom inflation that could make "Weak" SEO appear to give higher valuations than "Average" - Total Pages: Added more granular content value tiers (5, 10, 20, 50, 100, 200, 500+) and increased page count impact on the multiple, so 50 pages now clearly values higher than 5 pages - Financials Section: When Monthly Revenue is blank or £0, Profit Trend, Revenue Consistency, and Monetisation Methods are now visually disabled and excluded from all valuation calculations - Monthly Pageviews: Now directly contribute to the asset-based valuation (per-pageview value) and act as an engagement multiplier on traffic value. Pageview multiple adjustment increased from max +1.5 to max +3 - Minimum Valuation Floor: Reduced domain base values (Good: £500 → £100, Premium: £2,000 → £500), changed default domain quality to "Average" (£0), and stopped applying traffic/financial multipliers when those inputs are zero. A truly empty site now correctly values near £0 ALGORITHM CHANGES: - Traffic-dependent multipliers (trend, source quality, concentration, SEO strength, traffic proof) now gated behind monthlyVisitors > 0 - Revenue-dependent multipliers (profit trend, revenue consistency, monetisation diversity, revenue proof) now gated behind monthlyRevenue > 0 - Added pageview value contribution to asset-based calculation - Added pages-per-session engagement multiplier on traffic value - Financial internal scores now return 0 when no revenue exists - Multiple adjustments for page count expanded to 9 tiers (was 4) - Multiple adjustments for pageviews expanded to 6 tiers (was 4) with negative values for zero pageviews UI CHANGES: - Financials sub-fields (Profit Trend, Revenue Consistency, Monetisation Methods) are greyed out and disabled when Monthly Revenue is £0 or blank - Domain Quality default changed from "Good" to "Average" ================================== Version 1.1.0 - Correct Asset Valuation (March 11, 2026) --------------------------------------------------------- CRITICAL REWRITE: - Complete redesign of asset valuation algorithm - Eliminated fixed £ additions for quality factors (the root cause of all previous bugs) - Quality factors now use PERCENTAGE MULTIPLIERS only - Only tangible assets (domain, content library) contribute small fixed amounts DESIGN PRINCIPLES: - Base value = traffic + email list + social following + domain + content + included assets - ALL quality factors (niche, SEO, brand, age, risk, etc.) are MULTIPLIERS on the base - Zero traffic + zero email + zero social = near-zero value (correct behaviour) - Value scales proportionally with traffic/audience size ASSET VALUE FORMULAS: - Traffic: per-visitor valuation (£0.50-£3.50 based on scale) - Email: per-subscriber valuation (£0.50-£2.00 based on list size) - Social: per-follower valuation (£0.10-£0.25 based on following size) - Domain: £0 (average/weak) to £2,000 (premium/brandable) - Content: £0 (under 50 pages) to £3,000 (500+ pages) - Included assets: £500 per asset EXPECTED VALUATIONS: - 0 traffic, 0 email, defaults: ~£500 (domain value only) - 10 visitors, defaults: ~£600 - 1,000 visitors: ~£1,800 - 10,000 visitors: ~£30,000-£40,000 - 10,000 visitors + 5k email in finance: ~£60,000-£90,000 - 100,000 visitors: ~£350,000-£500,000 - 100,000 visitors + 5M email: ~£12,000,000+ WHAT THIS FIXES: - v1.0.3 bug: £33k-£55k for 10 visitors (caused by £30k+ fixed quality additions) - v1.0.0-1.0.2 bug: all dropdown changes barely affected valuation - Values now scale correctly from £0 to millions - Every dropdown genuinely affects the price through multiplier effects ================================== Version 1.0.0 -
