Before we talk about leads, let’s talk about the value of a booked job. Based on industry averages for a standard 3×2 Perth home (60m guttering, 6 downpipes), here is your net profit after all materials, subcontractor labour, and other costs are covered:
| Job Metric | The Number |
| Total Revenue | $3,660.00 |
| Total Costs: Installers, gutters, downpipes, pop rivets, silicons, clips etc. | $2,140.00 |
| Net Profit per Job | $1,520.00 |
Sound’s about right? An average job gutter replacement job is worth $1,520 in pure profit. This is the engine that funds your growth.
Let’s make this simple. Your investment in a professional local SEO service is $300 per week in the first year.
How many jobs do you need to land to cover that cost?
| Period | Total SEO Investment | Jobs to Break Even | The WIN |
| 1 Year | $15,600.00 | 11 jobs | One new job every 4.7 weeks |
To cover your entire annual SEO bill, you only need to land one extra job every 4 to 5
weeks.
If your SEO agency can’t deliver that, fire them. But if they can, everything else is profit.
Your customers are actively searching for you right now. The combined monthly search volume for your core services is 1,660 searches. Where do those leads go? They go to the Google “Local Pack”—the map and three business listings at the top of the search results. Studies show that the top three businesses in the Local Pack capture a massive 44% of all clicks for local searches 1 . This is the digital gold rush, and you need to be in the top three
to win.
Let’s be brutally conservative. We assume you only get a tiny 10% share of that traffic and convert just 2% of those clicks into a booked job.
| Metric | Year 1 Result |
| New Jobs Booked | 17.5 jobs |
| Total Profit from SEO | $26,600 |
| Net Profit (ROI) | $11,000 |
You bank $11,000 in net profit in Year 1. This proves the concept works. But this is just the
warm-up.
This is the key difference between ads and SEO. SEO is a digital asset that grows stronger every month. Your rankings climb, your reputation shines, and your lead flow compounds. We project your ROI over three years, assuming a conservative 50% increase in new jobs each year as your dominance grows.
| Year | Weekly SEO Cost | New Jobs Booked | Total Profit | NET PROFIT (ROI) |
| Year 1 | $300 | 17.5 | $26,600 | $11,000 |
| Year 2 | $300 | 26.25 | $39,900 | $24,300 |
| Year 3 | $450 (Advanced SEO) | 39.37 | $59,842 | $36,442 |
| 3-Year Total | $54,600 Investment | 83+ Jobs | $126,342 Profit | $71,742 WIN |
Year 2: Your net profit more than doubles to $24,300 with the same investment.
Year 3: You invest a little more for advanced SEO ($450/week) and your net profit
explodes to over $36,000.
The Big Win: Over three years, your total investment of $54,600 returns over $71,000 in
pure net profit, delivering over 83 new, high-value jobs.
You don’t take risks for $10k. You invest for $71,000.
This same ROI principle applies to other trades. SEO for builders follows the exact same model, but with higher-value projects. Whether you’re doing $3,600 gutter jobs or $750,000 extensions, the math works.
| Feature | Local SEO: The Asset | Google Ads: The Rental |
| Lead Flow | Builds momentum; grows stronger every month. | Stops the second your budget runs out. |
| Business Value | Builds equity. A top-ranking Google Business Profile is a tangible, sellable asset. | Rents leads. No long-term asset creation. |
| Trust | High. Searchers trust organic rankings and reviews. | Lower. Users know it’s an ad. |
The choice is simple: Keep paying to rent a spot at the bottom of the page, or invest to own the top three spots in the Local Pack.
