Trades is one of the most competitive industries on Google Ads in Australia. CPCs of $6–12 AUD per click, customers who request quotes from five different tradies at once, and a decision process that can take days or weeks. But when Google Ads is set up correctly, it consistently delivers the highest volume of qualified leads of any channel for Australian trade businesses. The difference between a profitable campaign and one that haemorrhages budget is almost always structure, not spend.
Why Google Ads works particularly well for trades
Trades have a defining characteristic: the person searching has a specific, often urgent need. Someone searching “emergency plumber Brisbane” or “licensed electrician Melbourne quote” is not browsing casually. They have a problem that needs solving, often today. That search intent makes Google Ads the most efficient lead acquisition channel for trade businesses compared to Facebook, Instagram, or lead aggregator platforms.
The challenge is competition. Larger operators with big budgets, comparison sites that generate leads to sell to multiple tradies simultaneously, and advertisers spending without optimising all raise the floor on CPCs. To compete profitably, campaign structure and keyword selection need to be precise. A trade business spending $1,500 AUD/month with good structure consistently outperforms one spending $3,000 with poor structure.
What keywords work and which ones waste budget
The difference between a profitable Google Ads account for a tradie and one that loses money is often the negative keyword list. Generic searches like “plumber” or “electrician near me” attract people at very different stages of intent, from someone with a burst pipe right now to someone curious about what a plumber costs. CPCs are high and conversion rates are low for the broad terms.
The keywords that convert best for trade businesses are high-specificity: trade type + location + intent signal. “Emergency plumber Sydney” converts far better than “plumber Sydney” even with lower search volume. “Licensed electrician Brisbane quote” converts better than “Brisbane electrician.” “Bathroom renovation cost Melbourne” outperforms “bathroom renovation Melbourne.”
Negative keywords are equally critical. Terms like “DIY plumbing,” “plumbing courses,” “plumber salary,” “how to fix,” and “apprentice electrician” should be excluded immediately. They indicate someone looking for information, not a service. A well-maintained negative keyword list can reduce wasted spend by 20–40% in the first few months, which at Australian CPC levels means hundreds of dollars saved per month.
How to filter tyre-kickers from your ads
A common mistake in trade campaigns is running a generic ad that does not qualify the customer. “Need a plumber? Call us today.” That ad attracts everyone: people three suburbs outside your service area, people wanting a quote with no real intention to book, and people with a $50 job when your minimum callout is $150.
Ad copy can be a highly effective filter. Including your service area explicitly (“Plumber Serving Inner West Sydney”), a minimum job size if relevant (“Residential and Commercial Jobs”), or a response time signal (“Emergency Callouts 24/7”) reduces click volume but significantly increases lead quality. The goal is not to maximise clicks. It is to maximise contacts from people who are actually going to book.
Your landing page filters too. A form that asks for the suburb, type of job, and preferred timing pre-qualifies leads before they reach you. You might lose 15–20% of total lead volume and double your booking rate from those leads.
What budget does a trade business in Australia actually need?
With CPCs of $6–12 AUD on competitive keywords and assuming a click-to-lead conversion rate of 4–8% (achievable for trade businesses with a well-built landing page), each lead costs between $75 and $250 AUD depending on the trade, location, and keyword competitiveness.
For a plumber or electrician with an average job value of $400–$800 AUD, a cost per lead of $100 is workable if the booking rate from leads is 30–40%. For a renovation builder with average job values of $15,000–$80,000 AUD, a cost per lead of $200–$300 is easily justified. The key metric is cost per booked job, not cost per lead.
The minimum recommended budget to generate enough data for proper optimisation is $1,500–$2,000 AUD/month in ad spend. Below that, lead volume is too low to optimise the campaign reliably. For context on total costs including management, see how much Google Ads management costs in Australia.
Which campaign types work for tradies
For trade businesses, Search campaigns with Smart Bidding (Target CPA) is the primary recommendation. Performance Max is not the right choice for lead generation: it cannot distinguish a $200 job inquiry from a $20,000 job inquiry and tends to allocate significant budget to Display and YouTube placements with low purchase intent.
The exception is using Demand Gen or YouTube Ads for trades with higher ticket sizes: kitchen and bathroom renovations, full home builds, commercial fitouts. A video showing a completed renovation project can generate highly qualified remarketing audiences at a fraction of the Search CPC, which then convert through Search at a lower total cost of acquisition. For trade businesses spending under $2,000 AUD/month, focus entirely on Search first. For those above $3,000/month, adding Demand Gen alongside Search is worth testing.
Local Services Ads: the complement most tradies miss
Google Local Services Ads (LSAs) are a pay-per-lead format that appears above standard Google Ads results, with a “Google Guaranteed” or “Google Screened” badge. For verified trade businesses (plumbers, electricians, HVAC, and others), LSAs can deliver leads at a lower cost than traditional Search campaigns.
LSAs require a background check and licence verification process, which most legitimate trade businesses pass easily. The cost per lead varies by trade and city but typically runs $30–80 AUD, lower than many Search campaigns. Running LSAs alongside a standard Search campaign gives maximum coverage across Google’s results page and complements a broader Google Ads strategy for Australian eCommerce or service businesses.
