The seller CPL that brokeevery Greek benchmark.
Six months of paid seller-lead ads and an organic content engine produced close to thirty signed exclusive mandates and over €6.8M in listing inventory.
CK Realtors.
A Keller Williams franchise in Athens residential real estate. Listing flow ran on referrals only, with no measurable seller-acquisition layer. House of Advanced built a Meta-native lead funnel and a cross-platform content engine, calibrated specifically for sellers requesting exclusive listing representation by CK Realtors, no shared agency, no multi-broker shopping. The funnel produced 2,186 exclusive-intent seller leads at €1.93 CPL (2,220 across the lifetime of the ad account at €2.45 blended CPL), closing close to thirty signed exclusive mandates and over €6.8M in listing inventory on roughly €5,000 of total media spend.
Four numbers that frame the engagement.
The economics of the engagement, up front.
Every figure pulled directly from Meta Marketing API and Metricool, no estimates, no extrapolations. The dashboard reads in one pass: spend, return, benchmark, channel split and monthly compounding.
~1,340× leverage on media spend, with each sole-agency exclusive mandate acquired for under €170 in advertising cost. The funnel did not chase shared-agency or multi-broker inquiries; every lead came from a seller asking CK Realtors to be their only representative.
€1.93 against every published alternative.

A brokerage acquiring listings on referrals alone.
CK Realtors is a Keller Williams franchise in Athens residential real estate. Competition for seller mandates in Attica is brutal. Sellers choose representation on digital reach, marketing capability and brand credibility, not on commission alone. Visible online presence drives listing inflow directly.
Before the engagement, CK acquired listings almost entirely through referrals. Flow was inconsistent, unmeasured and unscalable. No digital system was producing qualified seller leads at predictable cost. The brief was to build a measurable seller-lead acquisition engine without compromising the brand’s authority.
Run a content engine alongside paid seller-lead funnels. Engagement on the organic side reduces CPM on the paid side. CPL drops as volume scales.
Six failure points. Six rebuilt.
Referral-only acquisition was the symptom. Each cause sat in its own layer of the funnel. Each was rewritten in turn.
| What was wrong | What we rebuilt |
|---|---|
|
Static listings.
Conventional posts, no emotional engagement.
|
Performance content factory.
100+ pieces in six months, mostly video. Lower CPM, broader organic distribution.
|
|
Cold audiences.
No authority signal before the ad auction.
|
Organic authority layer.
Cross-platform engagement signals reduced paid CPL month over month.
|
|
External redirects.
Drop-off on every landing-page step.
|
Native Meta lead funnel.
Zero-friction submission inside Facebook and Instagram. €1.91 CPL.
|
|
Creative fatigue.
Set-and-forget campaigns degrading toward the mean.
|
Weekly A/B rotation.
Continuous creative refresh held link CTR at 1.10%, 22% above benchmark.
|
|
Form hesitation.
Sellers reluctant to submit to a brand they did not recognise.
|
Brand authority in creative.
Higher-intent leads, stronger downstream conversion to mandate.
|
|
Single-sided market signal.
Buyers and sellers acquired through separate, invisible tracks.
|
Parallel buyer demand visible.
Sellers committed faster seeing buyer interest in real time on the same brand.

The content engine, in motion.
Six pieces from the cross-platform engine running alongside the paid funnel. Property showcases, seller-education hot takes and authority content, all built to feed Meta’s engagement signals and reduce paid CPL across the campaign.
Five layers, one flywheel.
Five reinforcing layers, sequenced and run continuously. Each one cheapened distribution for the next.
100+ pieces, mostly video, across FB / IG / TikTok.
Meta lead form, no landing-page drop-off.
A/B testing held CTR 22% above benchmark.
Top 7 demographic cells locked at €2.18–€2.85 CPL.
Buyer demand visible inside the same ecosystem.
The data behind the transaction.
A reading of the engagement in numbers. Marketing transformation on the left, channel performance on the right. Every figure verifiable on request.
Six months on the Meta lead funnel.
The content engine, compounding.
- Facebook 1,351 71.6%
- Instagram 536 28.4%
Mandates spanned €65k apartments to €695k urban homes across 22 Attica regions, so the system performs across the full price range, not a single tier.
97% of ad-attributed mandates cross-match to a specific lead in the pipeline; close rate on attempted mandates: 93.9%.
We came in acquiring listings on referrals only, with no measurable seller pipeline. Six months later we had close to thirty signed exclusive mandates from the funnel House of Advanced built, at a CPL we could not have produced in-house. The system is now part of how the brokerage acquires inventory.
The brokerage was not the variable.
Over six months, the system generated close to thirty signed exclusive mandates and over €6.8M in listing inventory on roughly €5,000 of total ad-account spend, at a CPL below the floor of every published Greek Meta Ads benchmark. Lifetime, the CK Realtors ad account has produced 2,220 native lead-form completions; 2,186 of those came through the active Lead-Generation funnel that drove the mandate book. The intervention did not change CK’s market, its pricing or its service.
It changed the environment the market saw the brand in, and the economics followed. Engagement created reach. Reach created authority. Authority reduced acquisition cost. Acquisition at low cost compounded into scale.
What remains after the campaign window is the system itself. The content engine, the funnel, the measurement infrastructure and the audience signal continue to run in parallel with referrals, as a permanent layer of the brokerage’s seller-acquisition stack.
