For tradies in Australia, Google Ads delivers leads within days but stops the moment you stop paying. SEO delivers leads after 4–9 months but compounds for years afterward. The right answer almost always depends on cash flow: if you can wait six months, SEO wins on cost-per-lead by month 12. If you can't, run Google Ads now and start SEO in parallel.
This guide breaks down the real cost-per-lead numbers, time-to-first-lead expectations, and the exact decision framework we use with tradies in Wollongong, Sydney and the Illawarra. By the end you'll know which channel to prioritise first — and when (or whether) to add the other.
The Quick Answer: Use Both, But Start With One
For most tradies, the optimal long-term mix is 60–80% organic (SEO + Google Business Profile + word of mouth) and 20–40% paid (Google Ads + Local Service Ads). But you don't get there in one step.

Established tradies (3+ years, 10+ Google reviews, decent existing site) should start with SEO. The compounding cost-per-lead curve matters more than speed-to-lead. Most established tradies who run Google Ads at this stage are paying 3–4x more per lead than they need to.
Tradies in highly competitive metros (Sydney CBD, Eastern Suburbs, North Shore) usually need both, permanently. The keywords are too competitive and too valuable to leave on the table.
This isn't an ideological choice — it's a cash-flow and competition decision. The next sections give you the data to make it for your specific business.
How Google Ads Works for Tradies (And What It Actually Costs)
Google Ads for tradies has three main campaign types worth running. Search ads target keywords like "emergency plumber Wollongong" and appear at the top of Google for those exact queries. Local Service Ads (LSAs) charge per qualified phone call rather than per click and carry the "Google Guaranteed" badge. Performance Max campaigns let Google's algorithm distribute your budget across Search, Display, YouTube and Maps automatically.
For a typical Australian tradie, Google Ads costs $500–$3,000 per month in ad spend, plus 15–25% management fees or a flat $500–$900/month retainer. We break this down in detail in our Google Ads cost in Australia guide, but the headline numbers for trades:
- Search Ads CPC for tradies: $4–$12 average, $15+ for emergency keywords in Sydney
- Conversion rate (clicks-to-enquiries): 4–8% for well-built tradie websites, 1–3% for weak landing pages
- Cost-per-lead from Search Ads: $40–$120 typical, $25–$60 with LSAs for eligible trades
- Time to first lead: same day or next day after launch
- Time to optimised performance: 6–12 weeks (Google's algorithm needs ~30–50 conversions per ad group to optimise)
The biggest hidden cost in Google Ads for tradies is the landing page. Cheap agencies will set up campaigns pointing to your homepage, which typically converts at 1–2%. Dedicated landing pages built around the keyword intent convert at 5–10%. That's the difference between a $40 cost-per-lead and a $120 cost-per-lead on the exact same campaign.
How SEO Works for Tradies (And Why It Takes Longer)
SEO for tradies is fundamentally about three things: ranking your Google Business Profile in the Map Pack, ranking your website for service-area keywords like "plumber Shellharbour", and earning third-party citations and reviews that signal authority to Google.
The work breaks down across four ongoing streams. Google Business Profile optimisation includes service area definition, service catalogue, weekly posts, photo uploads, and review management. On-page SEO covers title tags, schema markup, content for each service and suburb, page speed, and mobile experience. Local citations mean consistent NAP (name, address, phone) listings across BrightLocal, hipages, OneFlare, Yellow Pages, and 30+ trade-specific directories. Content and links involve blog posts, suburb-specific service pages, and earning backlinks from local press, suppliers, and trade bodies.
Costs sit at $750–$2,500/month from a legitimate Australian SEO agency. Anything below $500/month is templated work that won't move rankings. We cover the full breakdown in our SEO for tradies guide.
The timeline is what makes SEO hard for cash-constrained tradies. Months 1–3 are foundations work where rankings barely move. Months 4–6 see early ranking lifts and the first measurable lead growth. Months 7–12 are when SEO starts to dominate paid channels on cost-per-lead. By month 18, mature SEO usually delivers 5–10x the monthly leads of month one at less than 30% of the cost-per-lead of equivalent Google Ads.
Cost Per Lead: Google Ads vs SEO Compared
The honest cost-per-lead comparison for Australian tradies looks like this:
- Google Search Ads (well-managed): $40–$120 per lead
- Local Service Ads (LSAs, eligible trades only): $25–$80 per lead
- New SEO campaign months 1–6: effectively infinite (no leads yet, $1,500/mo cost)
- SEO months 7–12: $25–$60 per lead as rankings stabilise
- Mature SEO (12+ months in): $5–$25 per lead
The "[mature SEO is $5–$25 per lead]" number is what makes the channel so attractive long-term — and what the cheap-agency Google Ads sales pitch never tells you. But you don't get there without paying the 6–9 month upfront cost in patience.
A worked example using Precision Plumbing data (the real numbers from their case study): in month one of working with us, they spent $1,500/month on Google Ads at a $90 cost-per-lead, generating 17 leads. Twelve months later, organic SEO traffic delivered 53 leads at an effective $34 cost-per-lead, while their Google Ads spend dropped to $600/month. Total monthly leads went from 17 to 70+ at less than half the original ad spend. The full numbers are in the Precision Plumbing Illawarra case study.
Speed to First Lead: Days vs Months
If you need leads next week, the honest comparison is brutal:
- Google Search Ads: First leads within 24–72 hours of launch
- Local Service Ads: First leads within 1–2 weeks (after eligibility verification)
- Google Business Profile optimisation alone: First lead lift within 30–60 days
- Full SEO campaign: First meaningful lead growth at month 4–6
Tradies who try to "do SEO" instead of running Ads when they're in a cash-flow crunch usually run out of runway before SEO matures. We've watched it happen multiple times. The right move is almost always to run Google Ads to bridge the gap while SEO compounds.
Long-Term Cost Curve: Why SEO Wins After Month 12
Plot cost-per-lead over 24 months on a graph and you get two very different curves. Google Ads is a flat horizontal line — same cost-per-lead every month, forever, scaling linearly with budget. SEO starts as a vertical drop at month one (high cost, no leads), bottoms out around month 4–6, then curves rapidly downward as rankings compound.
By month 12, the lines cross — SEO becomes cheaper per lead than Ads. By month 24, mature SEO is typically 3–5x cheaper per lead than the same business's Google Ads campaign. By month 36, the gap can be 8–10x.
The reason most tradies never see this curve is that they get impatient at month 5 (when SEO is still expensive per lead) and cut the SEO budget to "save money." That cancels the compounding before it starts. The agencies that show you 6-month SEO contracts are doing it because they know the numbers — under six months, you don't have enough data to judge.
The Decision Matrix: 6 Questions to Pick Your Channel
Run through these six questions honestly. Each one weights toward one channel or the other.
- How much cash do I have to wait 6+ months for results? Less than $5,000 of marketing runway → Google Ads. More than $20,000 of runway → SEO.
- How established is my business? Less than 12 months trading, no reviews, no website authority → Google Ads first. 3+ years, 10+ reviews, established Google Business Profile → SEO first.
- How competitive is my industry in my area? Plumber in Wollongong, electrician in Nowra → SEO is achievable in 6–12 months. Plumber in Sydney CBD, lawyer in Melbourne → SEO takes 12–24 months and Ads are basically required forever.
- What's my margin per job? Margins under 30% → Ads cost-per-lead has to be very low; LSAs preferred. Margins above 40% → either channel works.
- Can I deliver more jobs if leads spike? Already at capacity → SEO (predictable, slower scaling). Hungry for any work → Google Ads (turn it on, get leads tomorrow).
- What's my long-term plan for this business? Selling in 2 years → Ads (delivers immediate revenue). Building a 10-year asset → SEO (the rankings stay even if you stop spending).
When Google Ads Beats SEO for Tradies
Google Ads is the right primary channel when you're new (under 12 months in business, no domain authority), in cash-flow stress (need leads this month), in a high-competition metro (Sydney CBD, North Shore, Eastern Suburbs), or running a service that's purely seasonal (heating in winter, cooling in summer, pre-Christmas plumbing emergencies).
It's also the right channel when you're testing a new service category. Want to know if "rainwater tank installation" demand exists in your area before investing in SEO content? Run Google Ads for 60 days. The conversion data tells you whether to commit to SEO content for that service.
When SEO Beats Google Ads for Tradies
SEO is the right primary channel when you're established (3+ years, 10+ Google reviews, existing site), serving a defined geographic area (Wollongong, Illawarra, single Sydney suburb cluster), competing in moderate-difficulty markets, and you have 6–12 months of patience.
It's the only sensible primary channel for tradies focused on long-term business value. Every dollar spent on SEO builds an asset that keeps producing leads. Every dollar spent on Ads disappears the moment you stop paying.
Tradies serving the Illawarra and South Coast specifically have a structural SEO advantage — competition is moderate, search volume is meaningful, and Google Business Profile signals dominate the Map Pack. This is exactly the profile where SEO outperforms Ads on cost-per-lead from month seven onward. Our web design for tradies service is built around this approach.
The Hybrid Approach: Combining Both for Maximum ROI
The maximum-ROI play for established tradies is a graduated transition: start month one with 80/20 paid-to-organic spend split, and end month 18 with 20/80. Specifically:
- Months 1–3: $1,500/mo Google Ads + $1,000/mo SEO foundations
- Months 4–6: $1,200/mo Google Ads + $1,000/mo SEO (organic starts producing)
- Months 7–9: $800/mo Google Ads + $1,000/mo SEO (organic now dominant)
- Months 10–12: $500/mo Google Ads (kept on competitive metro keywords only) + $1,000/mo SEO
- Months 13+: $300–$500/mo Google Ads on top 3–5 commercial keywords + $1,000/mo SEO
This split keeps emergency lead flow constant while organic compounds. It also keeps competitor budgets honest — leaving Ads on for high-value commercial keywords prevents competitors from stealing position-1 paid clicks unopposed.
Common Mistakes Tradies Make With Both Channels
The four mistakes that cost tradies the most money in our experience:
Running Google Ads to a homepage instead of a dedicated landing page. The homepage tries to talk to everyone. The landing page talks to one specific buyer with one specific intent. Conversion rate difference: 2-3x.
Cancelling SEO at month 4–5 because "rankings haven't moved enough." This is the single most expensive decision you can make. Months 1–3 are foundations. Real ranking and lead lift happens months 4–9. Cancelling at month five wastes the entire investment.
Not running call tracking. Tradies get most leads via phone. Without dynamic call-tracking numbers, you can't tell which channel produced which call — and therefore can't optimise either channel.
Treating Ads and SEO as competing budgets instead of complementary channels. They serve different points in the buyer journey. Ads catch high-intent searchers ready to call now. SEO catches researchers who'll convert in the next 30 days. The data shows about 35% of buyers touch both channels before contacting.
For tradies who want help structuring this properly, we offer flat-fee Google Ads management and integrated SEO services that work together rather than competing for budget.
