What is a Heat Score, and when should I act on it?
A Heat Score is a 0–100 reading of how much your category is genuinely talking about its loudest subjects right now. Each subject is scored by its share of the posts, the reach and the engagement of the accounts you watch, multiplied by how many separate accounts and platforms it comes from; the catalog's number is its top three subjects added up. At 60 or above, write into it this week — the lead subject first.

The shape of it, drawn at a size the figures can be read. Placeholders, not a customer's numbers.
How is a Heat Score calculated?
Every subject the accounts you watch talk about is scored by its share of the catalog's attention in the last 30 days: its share of the posts at 40%, its share of the reach at 40% and its share of the engagement at 20%. Reach is views where a platform reports them; where it does not, each like stands in for impressions — 100 on Reddit, 50 on X.

Two multipliers then decide whether that loudness is evidence. Source diversity is 0.5 plus the number of separate accounts divided by the number of posts, capped at 1.5 — ten posts from ten accounts count three times what ten posts from one account do. Cross-platform corroboration multiplies by 1.15 when a subject appears on two platforms and 1.3 when it appears on three or more.
The catalog's own number is its three loudest subjects added up at full weight, 0.6 and 0.3, on a 0–100 scale. A subject that is all of the posts, from every account, on every platform, would score 100; a subject that is a fifth of the posts, a third of the reach and a tenth of the engagement, from four accounts on three platforms, scores about 44. Two rules hold the number honest at the edges: when there are posts but nothing scored, the catalog reads 15 to 20 rather than 0, and when fewer than 50 posts are almost all one subject from one or two accounts, the number is cut by 30%.
Beside the number, two readings the number alone cannot give. The stage says whether the catalog is getting louder: this week's activity against the average of the three weeks before — new, surging, rising, steady or fading. And every post carries its virality: its engagement rate against the same account's own average over 90 days, so a small channel's breakout reads as loudly as a big one's.
Why does one account posting ten times score so low?
Because one account posting ten times is one opinion, not a trend, and a score that cannot tell those apart is a score anybody can game by posting more. Ten posts from one account carry a diversity of 0.6; the same ten from ten accounts carry 1.5.
The detail+–
A single account does not score zero, though. Weak evidence is not no evidence, and zeroing it would hide the subject nobody else has noticed yet — which is occasionally the most valuable kind there is. The extreme case is named on the screen instead: when nearly everything in a small catalog comes from one or two accounts, the verdict says so and the number is held down.
Why is the reach baseline different on every platform?
Because a view is a different act on each one. An autoplaying short is not a chosen watch, and treating ten thousand of each as the same event ranks whichever platform inflates hardest. Where the score compares posts across time — the stage's week-over-week activity, and the searched-subject version below — each post is measured against what counts as a lot on its own platform: 100,000 views on TikTok, 40,000 on Instagram, 30,000 on X, 20,000 on YouTube and 15,000 on Reddit.

Those five numbers, and the weights above, are the ones most worth arguing with, which is why they are here rather than buried. If your category behaves differently from ours, you now know exactly which figure to disagree with.
What do the five bands mean, and what do I do in each?
Cold is under 20: attention is spread thin and nothing is moving. Cool is 20 to 39, warm is 40 to 59, hot is 60 to 79 and viral is 80 or above.
The detail+–
Hot and viral mean write into the named subject this week, because a surging subject has a window measured in days and the same piece published 30 days later is an archive entry. Warm means the strongest subject is gaining and has not peaked. Cool and cold are the calm windows for the evergreen pages that pay off slowly — reported as such rather than padded with something to do.
Why does the score depend on accounts I pick myself?
Because heat is only meaningful inside a category, and a category is defined by who it listens to. According to the Princeton and Georgia Tech researchers who measured generative search, the efficacy of visibility tactics "varies across domains, underscoring the need for domain-specific optimization methods" — the same holds for what counts as loud.
The detail+–
So the accounts are yours to choose, up to 25 read on each refresh, and they are filed into catalogs you name. Heat is read per catalog, so a subject running hot in one theme is not diluted by a quiet one next to it.
Is the score different before I have chosen any accounts?
Yes, and it says so on the screen. Before there are accounts to read, subjects are found by searching the platforms for your category's own phrases. That is a weaker claim than the one above — it says the platforms have something to show, not that the people you care about are talking about it — so it is scored differently rather than presented as the same number.
The detail+–
Source diversity is dropped entirely. A search returns different accounts by construction, so counting them would make the strongest signal in the account version meaningless here and every subject anybody looked up would come back hot. In its place: how much came back against how much was asked for, how far it travelled, how hard people engaged, and how recent it is — with volume gating the rest, because four posts are not a subject however well they did.
Recency counts for more in this version, at 45 per cent of the reading. When the sample is whatever a platform decided to return, a phrase whose results are all a month old has stopped moving — and that is the most useful thing a search can tell you, while the account version never has to ask it.
Also asked
- How recent does a post have to be to count? +
- Anything from the last 30 days. The first 7 days count in full, then a post decays in a straight line to nothing at the edge of the window.
- Can I compare Heat Scores between two of my catalogs? +
- Yes, and that is the comparison it is built for. Both are read against the same platform baselines, so a hot catalog and a cool one differ because the subjects differ, not because the scales do.
- What does the score show when the accounts could not be read? +
- Nothing — not a zero. A read that reached none of its accounts is reported as a failed read, with whose side the failure was on, and is not charged. A zero is only ever a reading of accounts that answered.
- Does a low Heat Score mean there is nothing to do? +
- No. It means the reactive work is not urgent, which makes it the right week for evergreen pages. A quiet category is reported as quiet rather than dressed up as an emergency.
- Is the score shown as a single number? +
- It is shown as a number, a band and the evidence behind it: how many posts, from how many separate accounts, on how many platforms. The number is the summary, not the argument.
