Why a range, not a number
If two reasonable, well-informed buyers can look at the same website and disagree on price, then the honest output of a valuation model is a range. Not a number with two decimal places.
Website valuation is an exercise in pricing future cash flows under uncertainty. The "right" number is the one a willing buyer pays a willing seller on a specific day.
That is unknowable in advance. What is knowable is the range within which a credible offer is likely to land, given everything observable about the site today. The website valuation pillar guide covers the underlying frame; why valuators disagree explains why three tools can return three different bands.
What the width tells you
The width of the band is the model's confidence statement. A narrow band — say ±10% on the midpoint — means the model has lots of comparable signal: a well-trodden niche, recent broker sales, a clean revenue trail, low concentration risk. A wide band — ±30% or more — means at least one of those signals is missing.
What the midpoint is and is not
The midpoint is the model's best single estimate given everything it can see. It is the number to use if someone asks you to pick one. It is not a guaranteed sale price. It is not a listing price. It is not an appraisal in the legal sense — RealSiteWorth is an automated estimate, not a formal valuation.
If the midpoint says $412k and the band is $318k to $506k, a credible buyer offer will most likely land inside that range. A negotiated final price could land anywhere in it — or, in unusual situations, outside it. Cross-check by browsing the public comp set and recent listings on Flippa and Empire Flippers.
How to actually use the output
Back to the data — the visual below grounds the same logic in the working numbers.
The honest disclaimer
RealSiteWorth produces an automated estimate. It is not a formal appraisal and it is not financial advice. The model is conservative by design — calibrated against working broker quotes (see the calibration page) — and ships with a confidence band so you can read both the estimate and the model's confidence in it. The how we use AI page covers the firewall between the deterministic engine and the narration layer.
If you want the figures explained in plain English, every report includes a valuation memo written from the computed numbers — see a sample report. The model produces the band. The memo explains it. Then run the analyzer on your own site to see your band.
