Every real estate or property-related business varies greatly.
No business can expect the same results as another. You offer different services, have different priorities, deliver different campaigns, target different geographical areas and have different budgets. However, Wordstream release industry benchmarks each year based on a sample of nearly 20,000 North American clients across 23 categories.
According to their 2022 study, Real Estate businesses averaged $1.36 USD (so about $2 AUD) cost per click, $44.70 cost per lead and 48.55 click through rate and 3.52% conversion rate.
You can imagine with a similar cost per lead to this, Google Ads delivers an extremely high return on investment for any property-related business.
