An editorial line is not a list of topics. It is a list of things you have decided not to publish, and that is what makes it usable by anyone other than the person who wrote it.
A list of topics tells a writer what is permitted, which is everything adjacent to your product. A list of exclusions tells them what to do with the eleven ideas they had this morning, which is the actual decision.
The reason this matters more than it should is that the evidence normally used to make format and channel decisions turns out to be weaker than its circulation suggests. Most of it surveys the wrong population.
The format research surveys marketers, not readers
This is the structural problem with almost every published statement about what works.
The most cited annual survey publishes its numbers honestly. Its latest edition states that the survey “was fielded between June 24 and August 14, 2025” and “drew 1,229 global responses”, of which the analysis covers “1,015 B2B marketers, mostly from North America.”
What it does not publish. Recruitment method, sampling frame, response rate. It is a self-selected sample from the publisher’s own distribution lists.
And the population is the wrong one for the claim. It asks marketers what they do and what they think works. Any figure from it describing a top-performing format is a marketer’s belief, and marketers are not a sample of buyers.
Which does not make it useless. It is a reliable picture of what the profession is currently doing, and that is worth knowing, particularly if your aim is to do something else.
A second survey supplies the consumption figures, and its bands overlap. One edition reports 1 to 3 at 28 percent, 3 to 5 at 42 percent, 5 to 7 at 19 percent. The values 3 and 5 sit in two bands each, so any aggregate built from them cannot be reproduced.
And its most recent edition contains no methodology at all. No sample size, no field dates, no demographics. It is sponsored by a content agency.
One further absence covers the format most B2B teams invest in most heavily. No published study with a stated methodology measures what proportion of a downloaded document is actually read.
Which produces an uncomfortable position, and a freeing one. There is no external evidence telling you which format works for your audience. That means the decision is yours, and it also means nobody can overrule it with a benchmark.
The engagement techniques the platforms suppress by name
Before deciding what to publish, it is worth knowing what one distribution system has published about what it actively demotes.
The mechanism is stated. “Our Content Distribution Guidelines describe the types of content we think may either be problematic or low quality, so we reduce its distribution in Feed for everyone. These reductions, also called demotions.”
Two named categories are exactly what engagement advice recommends. Clickbait links, and engagement bait.
And borderline material is reduced without violating anything. “We use personalization to reduce the distribution of content that doesn’t violate our policies but may get close.”
Which creates a specific trap. Techniques taught as engagement optimisation, provoking a reply, withholding the point, asking a question with an obvious answer, are named categories of demotion on the system they are designed to exploit.
The platform that matters most for B2B publishes almost none of this. Its help page says only that “our AI systems and algorithms consider hundreds of signals”, with no stages, no named signals and no demotion categories.
One sourcing warning worth carrying. Pages on that platform’s own domain under a content aggregation path look official and are aggregated member posts. They contain precisely the unsourced engagement multipliers this section is about. Domain is not provenance.
What follows for an editorial line. Optimising for reactions is optimising against a documented demotion list on one platform and against an undocumented system on the other. Neither is a stable strategy.
Six decisions, most of them negative, all of them portable to somebody who did not attend the meeting.
The subjects you will not cover. Not because they are uninteresting but because covering them would put you in a category you are not trying to win. This is the hardest one and it does the most work.
The claims you will not make. Numbers you cannot substantiate, comparisons you cannot support, and predictions you have no basis for. Writing this down converts a hundred future editorial arguments into one policy.
The formats you will not produce. Deciding in advance not to make short video, or not to make gated documents, removes a recurring debate whose evidence base does not exist anyway.
The reader you are writing for, named specifically. Not a persona document. One sentence identifying who the piece assumes the reader is and what they already know, because that determines everything about the register.
The standard of proof you hold yourself to. Whether an assertion needs a source, whether a figure needs a method attached, whether an example needs to be real. Publishing that standard is a differentiator in a field where most published statistics do not survive tracing.
And what a piece must do to be worth publishing. Not a word count. A test: does it say something the reader could not have assumed, and could you defend it to somebody who disagrees.

One framing is worth adopting explicitly, provided it is cited for what it is.
The observation. If companies change supplier roughly every five years, then about a fifth are in market in a given year, and about a twentieth in a given quarter.
What that is. An arithmetic deduction from an assumed purchase cycle. It is not a count of buyers, and it should not be presented as a measurement.
What it is useful for. It reframes the audience. Most people reading anything you publish are not going to buy this quarter, which means the piece is not a sales asset and cannot be judged as one.
Which changes the editorial test. Not “does this generate a lead” but “will this still be true and useful to someone who reads it eighteen months from now, when they are in market.”
And it changes what to write about. Subjects with a long shelf life, positions you can defend, and explanations of things that do not change quarterly. The opposite of a news cycle.
One consequence for measurement. A piece whose job is to be remembered eighteen months later cannot be measured in the month it is published, which is why editorial programmes get cancelled at month four.
Write the exclusions first. Three subjects you will not cover, three claims you will not make, one format you will not produce. That document is shorter than a content strategy and more useful than one.
Then set your standard of proof and publish it. In a field where the most repeated statistics do not survive being traced, a stated rule about sourcing is a genuine differentiator and costs nothing.
Stop optimising for reactions. One platform names engagement bait as a demotion category, and the other publishes nothing you could optimise against with confidence.
And judge pieces against the eighteen-month test rather than the month they appear in. If most of your readers are not buying now, the only sensible question is whether they will remember this when they are. An editorial line inherits its subjects and its register from the brand above it, so settling the positioning and the messaging first saves writing the line twice.
No published source answers that about readers. The surveys usually cited ask marketers what they do and what they believe, which is an opinion held by producers rather than a measurement of audience behaviour.
How many pieces of content does a buyer consume before purchase?
The survey that supplies those figures uses overlapping response bands, so any aggregate from it cannot be reproduced. Its most recent edition publishes no methodology at all.
Should we optimise posts for engagement?
One platform publishes named categories whose distribution it deliberately reduces, and engagement bait is among them. Techniques designed to provoke reactions are explicitly suppressed by the system they target.
What should an editorial line actually contain?
Mostly exclusions. The subjects you will not cover, the formats you will not produce and the claims you will not make are what make the line usable by someone else.
