One of the largest and most active early-stage VC investors in Germany — known for its work with tech companies — needed to move flagship in-person networking events online during the pandemic. The brief: cost-efficient digital sign-ups for an event built to connect startups, innovative thinkers, top operators, experts and visionaries. LinkedIn was the right surface; the question was how to use it properly.
Phased strategy — awareness, consideration, conversion
LinkedIn’s Campaign Manager is more sophisticated than most people give it credit for — not Facebook-level, but a long way past XING. We used its advanced targeting to run a six-week phased campaign: build visibility in phase one, narrow to engaged audiences in phase two, push to high-intent sign-ups in phase three.
Awareness — find the relevant rooms
Phase one targeted CTOs, CEOs, founders, and senior people in business development, IT, operations and project management — plus custom audiences built from the client’s own first-party lists. We showed them a polished 30-second video introducing the event with a direct “sign up” CTA. Two sponsored post variants ran in parallel: a short one focused on the networking opportunity, a longer one focused on the thought-leadership angle of the agenda.
Not sure who to target? Ask your own team. Instead of speculating in a meeting room, talk to the people in your call centre or your sales floor — the ones who actually know your customers. They give you targeting insight nobody else in the building can.
Consideration — where it got interesting
For phase two we cycled in a fresh cut of the video to avoid creative fatigue and stack on more “reasons to believe” — different angles of the event, different speakers, different proof points. New copy variants added a time-based push to lift sign-up intent. Creative versioning is not novel, but it works. The trick is keeping the core message consistent (the marketing “rule of seven”) while never letting the surface get boring.
The audience cut was tighter. We re-targeted everyone who had engaged with the awareness-phase video or the client’s company page, then split video viewers into two cohorts — those who watched 50% and those who watched 75% (our hottest leads). We also tested male- and female-specific creative cuts: the female-skewed cohort showed +10% CTR and +5% view-rate. Not enough to draw a finished conclusion from, but enough to keep testing.
Phase-two CTR ran 200% higher than phase-one. The whole point of phased targeting is that it stops you wasting the second half of your budget on people who already told you they were not interested. Fish where the fish are.
Conversion — last push, tightest audience
Phase three launched a third video against the tightest cohort yet — viewers who had watched 75% and 97% of the previous asset. Interestingly the 75% cohort outperformed the 97% cohort. We still do not have a fully satisfying explanation for that and we report it because every honest case study should have at least one result you cannot tidily explain.
Conversion-phase CTR ran +250% higher than the awareness phase and +17% higher than the consideration phase — clean evidence that progressive audience narrowing was doing the work it was meant to do.
What we learned about video length
Video completion rates climbed sharply across the funnel: 7.92% in awareness, 16% in consideration, 25.2% in conversion. The first video ran 30 seconds; the second and third ran 16 seconds. Because the consideration and conversion videos were the same length, we cannot fully isolate the effect of length on completion. But the direction matched LinkedIn’s own 2018 study showing videos under 30 seconds lift completion ~200% — the shorter cuts noticeably outperformed the longer one.
Useful rule when you next argue about cut-down length with the creative team: assume nobody watches to the end. Front-load the message, front-load the CTA.
Ticket-sales targets set by the client were exceeded. Cost per sign-up landed substantially below the client’s internal benchmark, and the campaign became the template for every subsequent event the firm ran online over the following 18 months. The piece that mattered most was the phased structure: the same media budget, deployed with progressively tighter audiences, produced 250% higher final-stage CTR than a single-blast equivalent would have.
