The definition

What is AI share of voice?

AI share of voice is your brand's mentions divided by the mentions of every tracked brand, on the same buyer prompts and AI engines. MentionX counts it from stored answers, so every mention behind the number opens to its answer.

Same prompts for every brand
You and each competitor are measured on one prompt set, so the shares compare like for like.
Mentions, not estimates
A mention is an answer that names the brand. AI engines don't publish prompt volumes, so MentionX doesn't invent them.
Tracked every week
Weekly re-runs show whether your slice grows, or a rival's does.
Which CRM is best for a small B2B sales team?

Most small B2B teams shortlist Kestrel, Pipewise and Halyard. Kestrel is the common pick for fast setup; Pipewise suits teams that forecast heavily.

    Find where you trail

    Sort prompts and engines by the leader's share minus yours.

  4. Weeks 2–4

    Win mentions where buyers ask

    Earn coverage on the sources engines cite for the leader, and publish pages for the use cases you're missing.

  5. Monthly

    Report the split

    Share of voice by engine and intent, next to each rival, with the answers behind it.

Reading the results

Five patterns worth acting on

Share of voice only means something next to your rivals. These patterns tell you where to look.

Every chart here uses one colour code

Coral: absent, or a rival aheadBlue: mentioned, not pickedMint: recommendedSilver: first choice, or you

Your share is flat while a rival's grows

You're holding mentions but losing ground in the category.

First move: Compare the new sources that cite the rival this month.

Citation & Source Intelligence

High share on one engine, low on another

Engines rely on different sources for your category.

First move: Check cited domains per engine before changing content.

Cross-Engine Monitoring

High share of voice, few recommendations

AI names you often but picks someone else.

First move: Read how answers describe you next to the brand they pick.

Brand Sentiment & Positioning

Strong on brand prompts, weak on category prompts

Your mentions come from buyers who already know you.

First move: Track category and use-case prompts separately.

Intent Coverage

A new name keeps appearing

A competitor you don't track is taking mentions.

First move: Add it to your tracked brands; competitors are unlimited.

Questions

AI share of voice, answered

The questions buyers ask before they start. Your first scan answers the rest with your own data.

What is AI share of voice?

Your brand's mentions divided by the mentions of every tracked brand, on the same buyer prompts and AI engines.

How is share of voice different from Recommendation Rate?

Share of voice compares your mentions with competitors' mentions. Recommendation Rate shows how often AI puts you on its shortlist. You can have a high share of voice and still be picked rarely.

Which competitors are included?

MentionX suggests the competitors AI already compares you with, and you can add any others. Competitors are unlimited from Spark; Starter includes 3.

Does MentionX use prompt search volume?

No. AI engines don't publish how often each prompt is asked, so MentionX measures share of voice on your tracked prompts instead of estimating volumes.

How often is share of voice updated?

Weekly. MentionX re-runs your full prompt set 4 times a month on every engine in your plan.

Can I see share of voice by engine?

Yes. Every share splits by engine and buyer intent, and every mention opens the answer it came from.
