For Australian SMEs, understanding marketing profitability isn’t about vanity metrics like likes or website visits. It’s about pinpointing the indicators that directly link marketing spend to revenue. We see too many businesses chasing the wrong numbers, and it’s costing them dearly. Focusing on a few key performance indicators (KPIs) will give you a much clearer picture of what’s working and what isn’t, allowing you to optimise your budget for maximum return.

So, which KPIs truly matter? It starts with understanding that marketing isn’t a cost centre, it’s an investment. Therefore, we need to measure return on investment. Here are the indicators we believe are most crucial:

• Customer Acquisition Cost (CAC): This is the total cost of acquiring a new customer through your marketing efforts. Calculate it by dividing your total marketing spend by the number of new customers gained. A lower CAC is obviously better, but it needs to be considered alongside customer lifetime value.
• Customer Lifetime Value (CLTV): How much revenue does the average customer bring in during their relationship with your business? Understanding CLTV allows you to justify a higher CAC if your customers are highly profitable over time.
• Marketing Qualified Leads (MQLs) to Sales Qualified Leads (SQLs) Conversion Rate: This measures how effectively your marketing is attracting the *right* kind of leads – those who are genuinely interested in your products or services and likely to become customers. A low conversion rate suggests your targeting or messaging needs refinement.
• Return on Ad Spend (ROAS): Specifically for paid advertising, ROAS tells you how much revenue you generate for every dollar spent on ads. A ROAS of 4:1 means you’re generating $4 in revenue for every $1 spent.

These aren’t isolated numbers. They work together. For example, a high ROAS is fantastic, but if your CLTV is low, the overall profitability might not be as strong as it appears. Regularly analysing these KPIs – monthly is a good starting point – will reveal trends and areas for improvement. As we move towards 2026, data privacy changes will likely impact tracking, so ensuring you have robust first-party data collection in place will be vital.

The key takeaway is this: stop focusing on activities and start focusing on outcomes. By consistently tracking and analysing these core marketing profitability indicators, you’ll be well-positioned to make data-driven decisions and maximise your return on investment. Your next step should be to implement a system for accurately tracking these KPIs and reviewing them regularly with your team.
