Most people set this up last. It should probably be first.
A watchlist is a small set of competitors, checked continuously, with breakouts and cadence changes surfaced to you. It costs about ten minutes to configure and then runs without you. That makes it the best effort-to-value ratio in the product, and the least glamorous.
What it does
Your teardown of the category (the deep, three-hour pass in how to research your competitors on YouTube) is out of date in a quarter. Channels change strategy, cadence shifts, someone breaks out.
A watchlist keeps it alive. Same public data, gathered on a schedule, with the four numbers that matter tracked over time: cadence, median views, engagement per view, and outliers.
The Morning Brief is the interrupt layer on top: it's what tells you a competitor broke out this week, rather than you discovering it a quarter later.
Setting it up
Competitors are set at intake, up to five, and you can manage them afterwards. If you skipped this at signup (a lot of people do), it's the highest-value ten minutes available to you.
The rule that matters most is the one about who's in the set:
Three types earn a place: the pace-setter your category copies, your closest true comparable, and one attention competitor (same audience, different product). That third one produces the most surprising signals, because they aren't bound by your category's conventions.
What lands in the Morning Brief
The brief sits on your Overview and surfaces what changed. Four things are genuinely worth interrupting you for:
A breakout. Something beat that channel's own median by a wide margin. Go and watch the first thirty seconds and read the comments. A competitor's breakout is a natural experiment run at their expense, sitting in public.
A cadence shift. A sustained change in posting rate, up or down. It usually precedes a visible strategy change by a month or two.
A new format. Something in their output that wasn't there before. Either they've found something or they're testing. Both worth knowing.
A sustained trend change. Median moving consistently over weeks, not one good week.
Everything else is noise. A single post doing slightly better than usual is the normal behaviour of a system with a long tail, not a message.
Share of voice
Across the set, Acumin computes your share of voice: your slice of the total measurable attention.
The level is fairly arbitrary; it's an artefact of who you put in the set. The trend is the signal. Held fixed over months, it answers the one question your own analytics structurally cannot: are you gaining or losing ground? Your views rising means nothing if the whole category doubled.
Where one account dominates the set, the read is reframed around that, rather than reporting "you have 4%" as though it were a verdict. That's deliberate: a technically true and practically useless number is still a bad number.
The rhythm
Weekly skim. Two minutes: did anything break out? Monthly read. Trend, not events. Quarterly teardown. Re-examine the set itself, including whether the right channels are still on it.
A watchlist without a scheduled moment to look at it decays exactly like the one-off research did.
The honest ceiling
Everything here is tier 1 evidence: public data. It's genuinely strong at this tier, and it has a hard limit.
You can see what competitors published and how it was received. You cannot see their retention, their traffic sources, their conversion, or their costs. Their most-viewed video may be the one their CFO wants cancelled. Don't read "more views than us" as "better strategy than us".
And a watchlist should change your behaviour a handful of times a year. If it's changing your plan monthly, you've built a machine for chasing. Your own outliers are a better guide than anyone else's.
How to use this tomorrow
Open your competitor set and cut it to six.
For each survivor, write one sentence: what would I do differently if this account changed? The ones where you can't answer come off. That deletion is the whole exercise: a watchlist earns its value by being short enough to actually read.
