# Your three numbers

> Where you stand, whether AI tells your story right, and whether you win the sale.

## Shelf Share

Your share of the shopper's attention across AI answers to your queries. Each answer is a shelf: the first products named get most of the attention, and the AI's pick gets more. 25% means you hold a quarter of it.

## Narrative Accuracy

How well the AI's description of your product matches the story you intend, from 0 to 100.

* A **high** score means AI mentions the things that matter about your product, and gets them right.
* A **low** score means AI is telling shoppers the wrong story: leaving out your key selling points, getting a detail wrong, or crediting one of your strengths to a competitor.

"The story you intend" isn't a guess. It comes from your [Brand Soul](/guide/brand-soul) and the facts on your own product pages. Every claim is checked against your own site: supported, contradicted or unsupported.

## Purchase Likelihood

How likely the shopper is to choose your product in answers where you appear, from what the answer says about product, price, where to buy and offers.

## Reading them together

* **High Shelf Share, low Purchase Likelihood:** you're considered but lose at the decision (price, offer, where to buy).
* **Low Shelf Share, high Purchase Likelihood:** you win when found, but aren't found enough.
* **Low Narrative Accuracy:** fix your story first.

## Knowing it's working

Each number shows its change since your last check. When you record what went live (`slingso published`), Slingso measures what it moved.

> *Since publishing this comparison, your Purchase Likelihood on "best creatine for women" rose from 20 to 65 on ChatGPT, and Gemini now cites your page.*

That's the shape of a result: a specific query, a specific change, a measurable move.
