Your three numbers

​

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 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.
