TL;DR
- The educational approach systematically outperforms the transactional approach. In a sector where the target audience is not actively searching for the solution, offering a free guide or explainer video generates 3 to 5 times more leads than a direct demo request. The target audience needs to be educated before being approached commercially. This was confirmed across all tested channels.
- LinkedIn Ads and Meta Ads serve two distinct and complementary objectives. LinkedIn generates high-quality decision-maker profiles — directors, managers, site managers — with shorter sales cycles, at an average CPL of around €50–€80. Meta generates massive volume at very low cost — €3–€5 per prospect — but requires quality filtering. Both channels are necessary: LinkedIn for immediately qualified meetings, Meta to feed automated email workflows and expand the pipeline.
- Ad fatigue happens quickly with a narrow target audience and requires constant creative refresh. In a niche market — public works site managers — we observed geographic saturation and declining creative performance. Authentic “field” formats — construction site, selfie, raw video — consistently performed better than overly polished designs. Thought Leader Ads with a “human experience sharing” approach also showed encouraging results, provided that any overly visible advertising approach is avoided.
Challenge / Objective
Cadoles was launching an innovative product in a niche market: the public works sector, characterized by a narrow target audience, long decision cycles, and low digital maturity. The company had no prior performance data on acquisition channels, no advertising history, and needed to validate LaCanne’s ability to generate commercial demand through digital channels.
The challenge was threefold: prove that the product could generate qualified leads with a limited budget, quickly identify the best-performing acquisition levers in a sector where the target audience is not actively looking for this type of solution, and maintain performance over time despite a narrow audience prone to ad fatigue.
The overall objective: validate a scalable acquisition model, generate qualified sales meetings, and structure a repeatable digital strategy to support the product launch over several months.
Strategy
We deployed a 6-month test & learn approach, testing several channels simultaneously to quickly identify what worked, with an evolving budget and continuous optimizations.
A. Multi-channel testing with direct lead generation as the priority
- Simultaneous activation of 3 channels: Google Ads Search — “GPS RTK” keywords — LinkedIn Ads — targeting site managers and directors — and LinkedIn outbound prospecting.
- Direct lead generation approach with product demo offers.
- Testing the “time savings” angle on very precise targets: managers, site managers, and operations directors in the public works sector.
- Objective: quickly validate which channel generated the best cost/quality ratio.
B. Pivot toward an indirect approach with a lead magnet
- Identification of a major limitation: the target audience is not actively searching for a GPS RTK solution, and meeting booking forms create too much friction.
- Pivot toward an educational approach with a lead magnet: a free 4-page guide explaining how GPS RTK works.
- Deployment of this approach on LinkedIn Ads and Google Ads.
- Immediate result: cost per lead reduced from €235 to €71, validating that the target audience needs to be educated before booking a meeting.
C. Launch of Google Demand Gen and continuous optimization
- Launch of Google Demand Gen with product visuals and a targeted “construction sector” audience, in response to Google Search’s difficulty converting — good CTR but few leads.
- Visual ad format combined with the lead magnet: 17 prospects for €537 — CPL of €31.60.
- Continuous optimization of LinkedIn audiences: exclusion of non-construction profiles, broader geographic targeting after saturation in Île-de-France and Grand Est.
- Refinement of outbound prospecting messages by focusing only on site managers, the most responsive target.
- Management of ad fatigue: regular creative refresh once frequency exceeded 3, testing of new formats — videos, infographics, TLA.
D. Meta Ads activation and final budget arbitration
- Opening Meta Ads to test volume potential at low cost.
- Validation of Meta as a high-volume tool with very low costs — between €2.74 and €4.20 per prospect.
- Progressive budget arbitration: 80% focused on LinkedIn Ads for profile quality — directors, managers — 15% on Meta for volume, and 5% on TLA — Thought Leader Ads on LinkedIn.
- Successful test of “field” videos and authentic formats with limited text overload.
- Identification of a quality challenge on Meta — the “needle in a haystack” effect — requiring downstream filtering, compensated by extremely low acquisition costs.
Results
- +60 qualified prospects/month.
- +5 qualified demos/month.
- €15.6 average multi-channel CPL.
