Choose the playing field: market, category, movement

Two identical launches, in two different categories, can have completely different odds from day one — before any marketing decision. Terrain matters: an accelerating category forgives mistakes more easily; a cooling one bills you for every single one.

The good news is that terrain leaves measurable traces. Categories don't cool in silence: first new ads decline, then launches thin out, then the leaders start moving their attention elsewhere. All of it is visible — if you look before the decision, not after.

What you'll be able to do after this chapter

• read your market's direction from a single page;
• tell a big category from a growing one — they're not the same thing;
• place any growth percentage on its base, so you don't confuse an early signal with a market.

The principle

A category healthy for entry shows several signals at the same time: active ads growing, new brands entering, new products appearing, existing ads running for months. A single, isolated signal is noise. And "big" doesn't mean "growing": the biggest categories are often high plateaus — plenty of demand, plenty of competition, zero growth. There you don't win with the ingredient; you win, if at all, with the offer and the execution.

The workflow in RavenBI

1. Open Trends and pick your market from the switcher at the top.
2. Read Market Movement: the direction of the whole market (active ads versus last month), new competitors, new products. This is the weather outside — the context for every decision below.
3. Look at Heating up / Cooling down: the categories accelerating or cooling right now, each with its percentage, brand count and reach behind it.
4. Go down to Category momentum: each category's trend over the last 10 weeks, with its stage — here you see whether the movement is a week old or a quarter old.
5. Check Where the money is: the categories ordered by reach, with each one's leader — so you know how big the table is you want to sit at, and who runs it.
6. Click into the category you care about — the next chapters start from there.

Market Movement, the categories heating or cooling and the 10-week momentum — the terrain, on a single page.

How to read the signals

• A category heating up on a small base (a few brands): early signal — put it under observation, don't bet on it yet.
• A category heating up on a large base: a real window, but with a clock — others see it too.
• A big, flat category: entering is justified only with a clear differentiation (chapters 3 and 6), not on "there's still room".
• A cooling category: not necessarily forbidden — but the burden of proof flips: you need a strong reason to enter against the current, not one to stay out.
• The whole market consolidating (active ads declining): windows don't disappear, but they narrow — positive signals need double confirmation (chapter 5).

The typical mistakes

• choosing the category by size, not by direction;
• reading a percentage without its base — the rule from chapter 1 first applies right here;
• looking at the category once — direction is a series, not a photo; that's why the 10-week momentum exists, not just this week's number;
• ignoring the weather outside: a "growing" category inside a generally consolidating market is a statement worth checking twice.

Exercise

Open Trends on your market and note: the direction of the whole market; your category — which list it appears in (heating, cooling, neither) and on what base; two neighbouring categories, as a benchmark. Then return to the sheet from chapter 1 and fill in the "window" line with what you saw — with the date next to it, because a month from now these numbers will be different.

Terrain is only the first layer: an entire category can look flat while, inside it, one specific problem is exploding with nobody serving it. That's exactly where the next chapter descends — the whitespace invisible at category level: problems, audiences and formats.
