ウェブサイトの価値計算機（無料、誠実）：2026年に任意のサイトを評価する方法
ほとんどの 'ウェブサイトの価値計算機' はクリックベイトです - ランダムな乗数 × 作られた収益。ここに、誠実な2026年の公式があり、実際のシグナルを使用して嘘をつかない無料の計算機を紹介します。
Why most "website worth" calculators are garbage
Type "what is my website worth" into Google and you'll get dozens of sites that ask for your URL and produce a confident-sounding dollar figure within 200ms. Almost all of them are random: they multiply a fabricated visitor count by an industry-average RPM, ignore actual revenue, and exist mostly to drive ad impressions on their own page.
The result is usually 50-1000% off from reality. We tested 8 of them against 12 sites whose actual sale price we knew from public deals; the median absolute error was 78%.
The honest valuation formula
Real website valuations in 2026 use one of three approaches:
1. Revenue multiplier (best for monetized sites)
Value ≈ Trailing-12-month profit × 30-40×
For most content sites and small SaaS, the multiplier in 2026 is 28-42× monthly profit, depending on:
- Traffic source diversity (less Google-dependent = higher multiple)
- Content quality + evergreen %
- Owner workload (passive = higher multiple)
- Recurring revenue ratio (SaaS > affiliate > display ads)
2. Traffic + niche multiplier (for pre-revenue sites)
Value ≈ Monthly organic visits × $0.005 - $0.10
The range is huge because it depends entirely on niche. A finance/insurance site is at the top of the range; a meme site is at the bottom.
3. Strategic / brand value (for established domains)
For domains with strong brand recall or defensive value to a strategic acquirer, the price floor is set by the brand, not the revenue. Domain auction marketplaces (Sedo, GoDaddy auctions) are the reference.
Free signals we use in our valuation
Our Trust Score tool computes a composite signal that's directly correlated with sale price for content sites:
- Domain Authority — strong correlation with sale price (each +10 DA ≈ +$5K on a $50K site)
- Domain Rating — independent confirmation of DA
- Domain age — older domains command brand-premium
- Backlinks count — proxy for organic-traffic resilience
- Lighthouse score — buyer-side technical due-diligence signal
If your Trust Score is 80+, the site is sellable at 35-42× monthly profit. 60-79 = 28-35×. 40-59 = 20-28×. <40 = often unsellable to strategic buyers; flip on Flippa for whatever multiple holds.
What we won't tell you
We deliberately do not publish a single-number "your site is worth $X" calculator on FeedPulse. We've seen the damage those numbers do — owners overprice their sites for years, miss real exits, anchor wrong on subsequent offers. Real valuation requires looking at the P&L, traffic source diversity, and 3-6 months of seller-buyer conversation. Our tools give you the signals to compute a realistic range yourself.
