How to Define Your LinkedIn ICP and Offer
Everything downstream inherits the ICP: the filters on the lead list, the first line of the message, the name on the campaign. Defining it means writing one line of role, company shape and situation that maps to real search filters, plus an offer written as an outcome rather than a feature list.
Run it when: before a list exists. Re-run it when results go flat and nobody can say who the campaign is actually for.
Time: 30 to 60 minutes. It is the cheapest hour in the whole system.
Depends on: nothing. This is the first SOP.

How to define your ICP and offer
1. Write the ICP in one line: role, company shape, situation.
"VP of Sales at a 51 to 200 person B2B SaaS company who posted on LinkedIn in the last 30 days" is an ICP. "Decision makers at growing companies" is a wish. The test is simple: if you cannot turn the line into search filters, it is not an ICP yet.
2. Name the trigger that makes them in-market now.
Static targeting gets static results. A trigger is something that changed recently: changed jobs in the last 90 days, hiring for the role you replace, posting about the problem, following your company page, viewing your profile. Each of those is an actual filter in SOP 05, which is the point. If your trigger cannot be expressed as a filter or a scrape, it is a theory, not a trigger.
3. Write the offer as an outcome, not a feature list.
4. Write the disqualifiers down.
Company too small to afford it, industries where the offer does not apply, geographies you cannot service, existing customers, competitors. Writing these down converts a vague sense of "bad fit" into filters you can exclude on, and stops the list from being padded with people nobody wants to talk to.
5. Fill in the brand profile in Reachium.
This is the part most people skip. The brand profile is what grounds AI-generated personalization: audience, tone, selling features, proof.
With it filled in, every line Reachium's AI writes later, in a first message or a verified opener, sounds like your company. Without it, they sound like every other tool, because the model is guessing. You open it from the content page in the app.
6. Size the market before you build the list.
Rough targets, applied in SOPs 05 to 07: under 500 is too narrow, 500 to 2,000 is the sweet spot for a targeted campaign, 2,000 to 5,000 suits a broader one, 5,000 to 10,000 wants narrowing, and 50,000 plus means you have not defined anything yet. Knowing the target now saves rebuilding the search later.
7. Name it after the ICP.
"SaaS founders 11-50 US" as a list name flows downstream into the campaign name and tells anyone opening the dashboard in three months what they are looking at. Dates and file names tell them nothing.
8. Read the one-liner out loud.
If it takes more than one breath, the copy built on it will need more than one breath too, and a connection request does not have one. Cut until it fits.
ICP and offer: do this, not this
Do this | Not this |
|---|---|
One ICP per campaign | Three ICPs in one list because the volume looked better |
A trigger that maps to a real filter | "Companies that seem like they're growing" |
Outcome with a number and a timeframe | "AI-powered LinkedIn automation platform" |
Disqualifiers written down and excluded | Sort the bad fits out later in the inbox |
Brand profile filled in before any AI copy | Generic generated lines nobody would claim |
Size the audience before searching | Build a 40,000-lead list and hope |
Questions people ask
What is an ICP?
An ideal customer profile is one line naming a role, a company shape and a situation: "VP of Sales at a 51 to 200 person B2B SaaS company who posted on LinkedIn in the last 30 days". If it cannot be turned into search filters, it is not an ICP yet.
How specific should a LinkedIn ICP be?
Specific enough that every clause maps to a filter, and narrow enough that one campaign serves one ICP. Three ICPs in one list because the volume looked better is the most common reason a campaign reads generic.
How big should the target audience be?
Under 500 is too narrow. 500 to 2,000 is the sweet spot for a targeted campaign, 2,000 to 5,000 for a broader one. Past 50,000 the ICP has not been defined yet.
