Improve your Share of Voice

By the end of this playbook you will know exactly which prompts you are losing, which competitor wins them and why, and what to publish to change that. The goal is a higher Share of Voice that holds up across several runs and multiple engines, not a one-day spike.

Before you start

You need a project with a running prompt set and a confirmed competitor set. Share of Voice is the share of brand mentions you earn on non-branded prompts, measured per engine against those competitors, so both need to be accurate before the work below pays off.

The actions

1

Find the prompts where you are absent

Open the visibility dashboard and sort your prompt set by coverage. The prompts where your answer never mentions you are your coverage gaps, and they are where Share of Voice leaks. Say you sell to startups and the prompt "best project management tools for startups" names Beta in four of four ChatGPT runs and never names Acme. That single prompt is dragging your category SOV down.

2

See who is named instead, and why

Open the actual answers for that prompt. Read what the engine says about Beta and check the sourcesit cites. Usually the reason is concrete: Beta appears on a "top 10 tools" roundup the engine trusts, or its own page answers the question in a clean, extractable way. Note the difference between a mention, a citation, and a source here. You want to understand which sources fed the answer, not just that you were left out.

3

Find the third-party sources engines trust

In the Sources viewyou can see which sites engines cite across your category, not just on one prompt. If the same three roundups, review sites, or community threads keep feeding answers about "project management tools for startups" and Acme is on none of them, that is your target list. Earning a presence on the sites engines already trust is faster than trying to be trusted from scratch.

4

Publish content engines will cite

Engines reward content they can quote directly. Give your answer page a clear, direct answer to the question, back it with specific statistics, and use tables for comparisons. The Princeton GEO study found that adding citations, statistics, and quotations to content improved visibility in generative-engine answers by roughly 25 to 40 percent.1 Apply the same structure on the third-party sites from step 3 where you can contribute. See GEO and AEO and the website audit for what extractable structure looks like.

5

Re-run and track over several runs

Keep the prompt set on its schedule and watch the coverage gaps from step 1. Because answers are probabilistic, judge the change by whether it persists across several runs and shows up on more than one engine, not by a single good day. A gap that closes on ChatGPT and Perplexity over a week is real progress; one good Gemini run is noise.

Worked example

Acme starts at 18 percent category Share of Voice on ChatGPT for startup project-management prompts; Beta sits at 47 percent. Reading the answers shows Beta is cited from two roundup articles and its own pricing comparison table. Acme earns a spot on one of those roundups and rewrites its comparison page with a direct answer plus a feature table. Over the next several runs, Acme's coverage on those prompts climbs and SOV settles around 31 percent on ChatGPT and 28 percent on Perplexity. That is the win: a durable, multi-engine gain, not a one-run blip.

What good looks like

You have improved Share of Voice when:

  • Your category SOV rises on at least two engines and holds across several runs (for example, 18 to 31 percent on ChatGPT, sustained over a week).
  • Prompts that were coverage gaps now mention you in most runs, not occasionally.
  • You can name the third-party sources now feeding answers about you, because you earned them on purpose.

Common mistakes

Judging on one run.A single day's jump can be sampling noise. Wait for the trend across runs and engines.

Publishing on your own site only. Engines weight third-party sources heavily. Your own page matters, but presence on sites they already cite moves the number faster.
