Advertising for B2B SaaS
Published · Updated
The problem is rarely the copy. It is that the audience is small, the cycle is long, and the platform that can reach the right people charges the most to do it.
You are paying for the facets
LinkedIn. Job title, function, seniority and company size exist nowhere else. If a campaign does not use them, it is paying LinkedIn prices for targeting Meta does cheaper.
That's a starting point rather than a rule. AdPlaybook scores all eight platforms against the strategy you pick and opens on the best fit, so you're changing a recommendation rather than choosing cold.
Long cycles break direct response
Competitor displacement or problem-aware, depending on whether the category is understood. Direct response into a six-month cycle measures the wrong thing and then gets cut for it.
Every strategy in AdPlaybook states how it usually fails before you choose it, because the expensive mistakes here are strategic rather than typographical.
No special ad category applies
Nothing about this kind of business puts you in a restricted category, so you keep the full targeting set. That's worth knowing rather than assuming, because the businesses that do get caught by one usually don't find out until an ad is rejected. We don't invent a warning to fill this section.
The ordinary rules still apply: every claim in the ad needs to be something you can point at on your own site. See what an unsubstantiated claim costs you.
The number that will stop you first
LinkedIn: 300. A tight ICP plus a two-cell test needs 600 people, not 300, and nothing warns you. It produces no error. The campaign goes live and simply doesn't deliver.
See the LinkedIn specs and every platform's floor.
You will not find out whether this worked for months
The thing you are buying is entry into a consideration set, and it gets decided by a committee in which nobody has the job title "customer". Several people have to not object. That is a different purchase from anything on the rest of this site, and an ad written to close it will read as pushy to every person whose agreement you actually need.
Which breaks attribution rather than merely weakening it. The deal closes long after the click, usually through a channel that had nothing to do with it — a referral, a conference, an inbound demo from someone who first saw your name in an ad they never clicked. Optimising to what the platform can see reliably moves budget toward the last touch and away from the one that created the opportunity.
Treat trial signups as the trap they are. They are the metric the platform can optimise toward and the one most likely to be uncorrelated with revenue, because the cheapest way to buy a signup is to find people with no budget and no urgency. If you cannot pass a real outcome back, be honest that the campaign is being steered by a proxy.
What it does with a long sales cycle
It reads your site, works out what you sell and to whom, recommends the approach that fits, and writes the campaign. Then it checks the copy against LinkedIn's published character limits, traces every factual claim back to a line on your own site, runs the compliance obligations above, and tells you what it could not check.
