How do you know if a sample size is statistically significant?

A sample size becomes statistically significant when it can reliably represent the population, which for most research means achieving at least a 95% confidence level and a 5% margin of error. While the exact number varies, you generally need at least 30 participants for basic statistical analysis.

Can a small sample be representative?

Yes, a small sample can be representative if it accurately reflects your population’s characteristics. The method of selecting participants is more critical than the sample size itself. However, be aware that smaller samples usually have a higher margin of error and might not detect subtle differences.

What is the difference between Slovin’s formula and Cochran's formula?

Slovin’s formula is a simpler method that only requires population size and margin of error, making it suitable for quick estimates with known populations. Cochran’s formula is more complex and accurate, as it also considers the confidence level, making it the standard for research requiring higher precision, especially with large or unknown populations.

When should I use a 90%, 95%, or 99% confidence level?

Use 90% for preliminary or exploratory research. Use 95% for most standard research, as it offers a strong balance of confidence and feasibility. Use 99% when you need extremely reliable and precise results, such as in medical studies or critical business decisions, as it requires a larger sample size.

Can I use the same sample size for different population sizes?

Yes, surprisingly, once a population is very large (e.g., over 20,000), the required sample size for a given confidence level and margin of error stays relatively stable. This means you might need a similar sample size to survey a large city as you would an entire country.

One person, in a few words.

What are they looking for?

The need, in their words, before any brand comes to mind.

What matters most to them?

Their priority, not your selling point.

WHAT WE WILL ASK AI ASSISTANTS Live preview

I live in United States. I'm a busy parent with two young kids. I'm looking for a breakfast cereal for the kids, and what matters most to me is less sugar, but something the kids will actually eat. What should I look for to choose well?

How the AI Brand Visibility Checker works

The AI Brand Visibility Checker shows you which side your brand is on.

How to read your results

It’s a snapshot, not a ranking.
ChatGPT generates each answer on the spot. The same question asked tomorrow, or by a different shopper, can give different answers. Read the pattern in the answer, not the exact wording.

The two conversations tell you different things.
The first shows whether your brand is in the shopper’s consideration set when nothing points to it. The second shows how ChatGPT describes your brand once it’s on the table. A brand can be absent from the first and well described in the second, or the reverse.

Facts need checking.
ChatGPT can state prices, ingredients or claims that are outdated or wrong, and OpenAI itself recommends checking its answers. Your reading lists them under Points to check so you can verify them before acting on anything.

What an AI answer can't tell you

An AI Brand Visibility Checker tells you what an assistant says about your brand. It can’t tell you what real consumers think.

Whether people in your market know your brand, would consider it, and choose it over your competitors is a separate question. So is whether that’s improving or slipping. Only consumers can answer that.

That’s what Standard Insights Brand Tracking measures.

We survey real consumers in your market on awareness, consideration, preference and purchase, against your direct competitors, over time.

Our AI Brand Tracking reading can be added alongside it. You see whether what AI says and what consumers think tell the same story.

Methodology

Assistant: ChatGPT, using the model most people get by default. We note any model change.

Web search: On. ChatGPT can search the web while answering, as it does for most users.

Conversations: two separate conversations, so the direct question about your brand isn’t influenced by the first answer.

Shopper: written from your inputs, in the first person, set in the market you choose.

Analysis: both answers are read and summarised in a structured reading. No score is invented. The reading reports what ChatGPT said and what that means for your brand.

Who it's for

Brands that want to know whether AI assistants put them in front of shoppers, and what they say when they do.

Agencies that want a quick, concrete reading of where a client’s brand stands in AI answers, to open a conversation or prepare a pitch.

Frequently Asked Questions

What is an AI Brand Visibility Checker?

It’s a free tool that shows how visible your brand is in AI assistants’ answers. Ours puts a real shopper’s question to ChatGPT and sends you a written report: whether your brand is recommended, who is recommended instead, and what ChatGPT says when asked about you directly.

Does the AI Brand Visibility Checker cover Google's AI answers?

No. The AI Brand Visibility Checker reads ChatGPT only. Google’s AI Overviews and AI Mode work differently. Google explains how in its guide to AI features in Search.

Is it really free?

Yes. The AI Brand Visibility Checker is free and one-off. You receive one reading by email, with no commitment.

Which AI assistant do you check?

ChatGPT, the most widely used AI assistant. Our paid AI Brand Tracking, which comes with Brand Tracking, also covers Gemini and Perplexity.

Why do you ask for a professional email?

The check is designed for brands and agencies, and we send the reading to a verified work address. Personal addresses aren’t accepted.

If I run the same check again, will I get the same result?

Not necessarily. AI assistants generate each answer on the spot, so wording and brand lists can vary. A single reading shows you a likely answer, not a fixed position. Measuring how often and how consistently your brand appears takes repeated readings over time.

Can an agency run it for a client?

Yes. Agencies use the AI Brand Visibility Checker to read where a client’s brand stands before a meeting or a pitch. Select “An agency” in the first step, enter your work email and your client’s brand name.

Does what ChatGPT says reflect what consumers think?

No. ChatGPT draws on what’s written about your brand online, not on what consumers in your market actually think or buy. The two can differ widely. That’s why we measure consumer perception separately, through Brand Tracking.

How long does it take?

About a minute to fill in, and a few minutes for the reading to reach your inbox.
