Two different questions
Reach answers "how many people saw this?" Resonance answers "does the market believe what we promise, and can it say it without us?" Both are useful. They are just not the same thing, and one cannot stand in for the other.
Reach is mostly a measure of your distribution: the algorithm, the timing, the ad budget, the hook. It can rise because a post was funny, controversial or boosted, none of which means anyone understood your offer. Resonance is a measure of what stuck. It shows up when a customer writes a review, recommends you in a thread or introduces you to a friend, and uses words that match the promise you made.
That is why the resonance reading on the Promise Index is "the market's alone." It is scored only from arm's-length, verbatim evidence. Reach numbers do not count toward it at all.
The evidence ladder
Not all evidence is equal. Here is how to rank what you find, from not counting at all to the strongest signal a brand can get.
| Evidence | Examples | Counts as resonance? |
|---|---|---|
| Reach | Followers, views, impressions, likes, open rates, traffic | No. People saw something. |
| Your own voice | Your team, partners or investors describing you | No. The market is not speaking. |
| Prompted or shaped | Testimonials you requested, edited or picked; customers repeating your tagline | Weak. Reads as Parroted. |
| Unprompted, own words | Public reviews, forum threads and posts that describe your promise in the customer's language | Yes. Reads as Adopted. |
| Used to recommend you | "You should talk to them, they are the ones who..." in a thread, reply or intro | Strongest. Reads as Championed. |
The bands come from the resonance reading: Silent (no one mentions the promise yet), Parroted (your words come back to you), Adopted (their words, your promise) and Championed (they use it to recommend you). The full scoring is in how to measure market fit.
Where resonance actually shows up
- Public reviews. Google, Yelp, G2, app stores, marketplaces. Read them for the words customers use, not the star rating. The reviews vs homepage guide shows how to compare them with your headline.
- Threads you were not tagged in. Search your name, and your name plus your category, on Reddit, X, LinkedIn and niche forums. A stranger answering "who should I use for this?" is the clearest evidence there is.
- How people introduce you. Referral emails, intro messages, podcast intros. Do they describe you with your promise, a version of it, or something else entirely?
- Replies and quote posts that restate your idea. Not "great post" but someone explaining your point to their own audience in their own words.
Some signals are useful for you but private: sales call notes, "how did you hear about us?" answers, support tickets. Read them, because they often hold the exact phrase you should be using. Just keep them separate from public, arm's-length evidence, because a scored read can only check what anyone could check.
The 10-minute resonance ledger
- Write down your promise. Your one-sentence promise or homepage headline, at the top of a page. (No promise yet? Start with how to write a brand promise statement.)
- Set up five columns. Date, source, the exact words, prompted or unprompted, and Same, Close or Different compared with your promise.
- Search three places. About five minutes across public reviews, a search of your name in forums and social posts, and referral or intro messages in your inbox.
- Copy words, not numbers. Paste quotes verbatim. Leave out follower counts, views, likes and anything your team wrote.
- Read the ledger. Strike out prompted quotes and lines that only repeat your tagline. What is left, in the market's own words, is your resonance evidence. Match it to a band.
How to read what you find
- Nothing left. Silent. For a young business this is on schedule, not a failure. Work on being visible and specific first: the swap test and messaging consistency are better uses of this month than chasing reach.
- Only your tagline, echoed. Parroted. The words travelled. Watch whether customers start to describe the experience in their own language.
- Their words, your promise. Adopted. The promise is landing. Use their phrasing on your site, because it is already proven to be repeatable.
- Their words, a different promise. The market may be telling you what you are really known for. Decide whether to change the copy or the delivery before you spend more on reach.
An illustration (made-up business, not a client)
A small meal-prep service posts a short video that spreads well beyond its usual audience. Followers jump, and the founder feels the brand is working. The ledger tells a different story. Its homepage promises "chef-quality meals." The reviews, written unprompted, keep saying versions of "I finally stopped skipping lunch at work" and "it is the only reason I eat vegetables on weekdays." The video brought reach. The reviews show resonance, and they point to a different promise: a reliable weekday habit, not restaurant food. That is the line worth putting in front of the next wave of viewers.
So what is reach for?
Reach is the input. It puts your promise in front of people. Resonance is the output. It tells you whether the promise survived contact with them. Use reach to get seen, then judge the work by what comes back in the ledger. If the reach went up and the ledger did not change, the message is the thing to fix, not the budget.

Questions
What is the difference between resonance and reach?
Reach is how many people saw something you published. Resonance is whether the market describes your promise back to you, in its own words, without being prompted. Reach measures your distribution. Resonance measures their belief.
Do followers, likes or views count as resonance?
No. They show that people saw something, and sometimes that they enjoyed it, but not that they understood or believe what you promise. A post can travel far and leave nobody able to say what you do.
Do testimonials count as evidence of resonance?
Weakly. Quotes you asked for, edited or chose are useful on your site, but you shaped them. The stronger evidence is what customers write on their own: public reviews, forum threads, posts and recommendations you did not request.
What does arm's-length evidence mean?
Evidence the business did not write, prompt or edit. A public review a customer chose to leave, a thread where someone recommends you, or a post that describes you without tagging you. Your own team's words and quotes you drafted do not count.
What if I cannot find any resonance evidence?
For a young business that is normal and on schedule. It reads as Silent. The job then is to make the promise clear and visible everywhere, so that when people do talk about you there is something specific for them to repeat.
Can you buy resonance with ads?
No. Paid reach can put your promise in front of more people, which gives resonance a chance to happen. Whether those people then describe you in their own words is the part money cannot buy, which is why it is the better signal.
How often should I check resonance?
Monthly is enough for most small businesses and personal brands. Add new verbatim quotes to the same ledger each time and watch whether they move from silence, to your tagline repeated back, to people using their own words.
