Two Tools, Two Different Scores. Which One Do You Believe?

By the Searchestra team· · 1 min read·Full guide →

You demo two AI visibility tools and they report different share-of-voice numbers for the same brand. Tempting to believe the higher one. Wrong instinct. The number you should trust is the one the vendor can actually explain, because a confident figure you cannot reproduce is worth nothing.

The higher number is not the truer one

Tools disagree because they use different prompts, platforms, competitive sets and definitions, all legitimate choices that change the result. Picking the vendor with the flattering number, instead of the one who discloses how it was produced, is how you end up defending data that falls apart under a single hard question.

What actually decides trust

Ask the vendorIf they cannot answer
How is the prompt set built?The number is unrepeatable
Which engines and versions?Coverage is a black box
What counts as a mention or citation?The definitions are hidden
How do you handle model updates?Trends may be artifacts

Buy the number you can defend

Searchestra uses a versioned, brand-neutral prompt set and reports per engine, so its numbers are interpretable and stable, not a flattering figure you cannot reproduce. Transparency is the whole point.

Key takeaway.

When tools disagree, trust the transparent number, not the higher one; buy data you can reproduce and defend.

Frequently asked questions

Why do two AI visibility tools disagree?

Different prompt sets, platform coverage, competitive sets and definitions. Two tools can measure the same brand and legitimately differ.

Which tool should I trust?

The one that discloses its methodology, not the one with the higher number. Pick what you can interpret and reproduce.

Is a higher score better?

Not if you cannot reproduce it. An unexplained number is a liability, not a win.
