The vendor paid advertising conversation hasn’t changed much in 25 years. Agent recommends a marketing budget. Vendor asks why it costs so much. Agent says something about “maximum exposure.” Vendor reluctantly agrees or pushes back hard.

What’s changing is that some agents are bringing actual data to this conversation instead of vague promises. And it’s making a measurable difference in how much vendors trust them and how much they’re willing to invest.

The Trust Gap in VPA

Vendors suspect that agent-recommended marketing spend benefits the agent more than the vendor. They worry about paying $12,000 for a campaign that a $4,000 campaign would achieve equally well. Those suspicions aren’t always unfounded — I’ve seen agencies recommend one-size-fits-all marketing packages that don’t reflect the specific property’s needs.

Data is the antidote to suspicion. When an agent can show a vendor exactly what their recommended spend will achieve — backed by evidence from comparable campaigns — the conversation shifts from opinion to analysis.

What the Data Actually Shows

Here’s where it gets interesting. The portals generate enormous amounts of data about listing performance, and most of it is available to agents who know where to look.

REA Group provides detailed listing performance metrics through their agent dashboards. For any given listing, you can see:

• Total views: How many unique users viewed the listing
• Engagement rate: What percentage of viewers clicked through to enquire, save, or share
• Search position: Where the listing appears relative to competitors in the same suburb and price range
• Audience demographics: Broad data about who’s viewing — first-home buyers, investors, downsizers

Domain offers similar metrics through their agent tools, plus comparative data showing how your listing performs against suburb benchmarks.

The agents winning VPA conversations are pulling this data from previous campaigns and building evidence-based presentations. Not “trust me, premium works better” but “here’s what happened with three comparable properties in your suburb over the last six months.”

Building a VPA Evidence Pack

I’ve been helping agencies build what I call a VPA Evidence Pack — a standardised presentation that supports every marketing recommendation with data. Here’s the structure.

Comparable Campaign Analysis

Pull 3-5 recent listings from the same suburb, similar property type and price range. For each, show:

• The marketing package used (standard vs. premium placement)
• Total listing views generated
• Enquiry volume
• Days on market
• Sale price relative to price guide

When vendors see that a Randwick three-bedroom house with premium placement averaged 2,400 views and sold in 18 days, versus a similar property with standard placement that got 900 views and sold in 34 days, the value proposition becomes concrete.

Seasonal Timing Data

Campaign performance varies significantly by season in Sydney. Autumn and spring campaigns generally outperform winter listings on most metrics. But the degree of outperformance varies by suburb and property type.

Show the vendor how their listing timing affects expected performance. If they’re listing in March, show them that Inner West autumn clearance rates have historically tracked 5-8 points above winter rates. That context supports your recommendation about campaign intensity.

Price-Point Specific Evidence

Marketing ROI isn’t linear across price points. For properties under $1 million, the gap between standard and premium listing performance is modest — maybe 15-20% more views. For properties above $2 million, the gap widens substantially because the buyer pool is smaller and more targeted.

This means your VPA recommendation should scale with the property’s value. A $600,000 Bankstown apartment doesn’t need the same marketing investment as a $3.5 million Mosman house. Showing the vendor you understand this builds credibility.

Digital vs. Traditional Allocation

Here’s where data really helps. Track the source of your buyer enquiries across recent campaigns. Most agencies find that 75-85% of genuine buyer enquiries now originate from portal listings and digital channels. Print advertising, letterbox drops, and window displays generate the remainder.

Present this data when recommending how to split the VPA budget. If digital channels are generating 80% of your enquiries, the marketing spend should reflect that — not split 50/50 because “we’ve always done print.”

Making It Practical

Building a VPA Evidence Pack sounds labour-intensive, but the data is increasingly accessible. PropTrack’s agent tools provide suburb-level performance benchmarks. The REA Group and Domain dashboards give you campaign-specific metrics. CoreLogic’s RP Data platform lets you pull comparable sales with detailed marketing history.

The trick is systematising it. Build a template. After every campaign, update it with the performance data from that listing. Within six months, you’ll have a suburb-specific evidence base that no competitor can match.

I’ve also noticed a downstream benefit: well-funded campaigns that generate strong buyer competition tend to produce smoother settlement outcomes. The winning buyer has competed hard and is less likely to delay or renegotiate. That’s valuable data to share with vendors who view VPA as a grudging expense.

What Vendors Actually Want

Vendors don’t want a marketing lecture. They want confidence that the recommended spend will produce results, transparency about where the money goes, and evidence that the recommendation is tailored to their property rather than a generic package.

Data provides all three. It replaces “trust me” with “look at this.” The agencies that build this capability now will have a genuine edge in listing presentations. The data exists. The tools exist. The only question is whether you’re going to use them.
