Methodology

How Nadelio measures, and why the interval matters.

Most AI visibility tools hand you a single number. That number is a noisy sample of one on a model that answers differently every time you ask. Nadelio measures across several runs and reports the score with its confidence interval, so you know whether a result is real or just noise.

What we actually measure

You type one brand. Nadelio identifies your competitive set, then measures two territories side by side:

  1. Google (SERP). Each buyer-intent query runs against live Google for your market, geolocated to the right country and language. We record where every brand ranks.
  2. AI answers. The same buyer questions are put to an AI assistant. We record which brands it recommends, in what order, and whether each is the primary answer or a passing mention.

The GEO score combines three equally weighted parts, each on a 0 to 100 scale: your Google share of voice, your coverage in AI answers, and the quality of your AI rank.

Why one number lies

Ask an AI assistant the same question ten times and you will not get the same answer ten times. The models are non deterministic by design. A tool that runs your query once and prints a score is reporting a coin flip as if it were a fact.

In a controlled test, an aggregate mention rate of 10.8% corresponded to a true recall of 1.9%. Nine points of difference, entirely because nobody bounded the noise. A score without its interval is marketing, not a measurement.

So Nadelio runs the AI measurement several times and looks at the spread of the results, not just the average.

The confidence interval

From the runs we compute the average score and a 95% confidence interval around it: the plain standard error of the mean, times 1.96. Explained in one line to anyone: the true value is very likely within this band.

We report it as 42 ± 6, never as a bare 42. And we refuse to put an interval on a single run: with one measurement, we say so plainly rather than inventing a false precision.

The paid Deep Audit runs more measurements, which tightens the interval. The free audit shows an honest but wider band. Nothing is hidden behind the paywall except the number of samples.

Reading the verdict

The interval drives one honest label, so you know at a glance how much to trust the number:

StableThe band is tight. This is a number you can present to your board.
ModerateSome spread. Directionally useful, worth a second look before you act on it.
VolatileWide band. The model is inconsistent here. Do not cite this as a fact yet.

This is also why a lead can be an illusion. If your score is 44 ± 9 and a rival sits at 48 ± 11, the bands overlap: the rival is not really ahead, the gap is noise. Nadelio says so. A tool showing bare numbers would call it a loss.
