How much should a Wollongong small business spend on Google Ads?

For most Wollongong small businesses, a starting budget of $1,000–$2,000 per month gives enough data to optimise and enough volume to generate leads. Tradies and service businesses with high-value jobs ($500+) often see strong ROI at $1,500–$3,000/month. eCommerce and retail businesses typically need $2,000–$5,000/month to compete effectively. The right budget depends entirely on your industry, average job value, and conversion rate.

What is a good cost per click for Google Ads in Australia?

Average CPC in Australia varies by industry: services (plumber, electrician, lawyer) typically range $5–$25 CPC; retail/eCommerce $0.50–$3; healthcare $4–$15; legal $15–$60+. Wollongong CPCs tend to be 20–40% lower than Sydney for equivalent keywords, which makes local Google Ads campaigns very cost-effective for Illawarra businesses.

How long does it take for Google Ads to work?

Google Ads can generate leads from day one — unlike SEO which takes months. However, the first 30–60 days are a learning phase where the algorithm optimises your campaign. Expect the first month to be more expensive per lead than subsequent months as quality scores improve and you remove underperforming keywords and ads.

Is Google Ads worth it for Wollongong businesses?

For businesses with high job values (trades, professional services, legal, health) Google Ads is typically excellent value in Wollongong because local keyword costs are lower than capital cities but purchase intent is just as high. For low-margin retail with competitive national players, it can be harder to make the numbers work. The key is having a landing page that converts and tracking your cost per lead accurately.

Do I need a landing page for Google Ads?

Yes — sending Google Ads traffic to your homepage is one of the most common and costly mistakes we see. A dedicated landing page for each campaign (matching the ad's promise and call to action) typically doubles conversion rates, which halves your effective cost per lead. This is where most Google Ads campaigns lose money before they even start.

How Much Do Google Ads Cost for Wollongong Businesses? (2026 Guide)

"How much does Google Ads cost?" is one of the most common questions we hear from Wollongong business owners — and the honest answer is: it depends enormously on your industry, your competition, and how well your campaigns are managed.

This guide breaks down realistic costs for Illawarra businesses, explains the factors that move your costs up or down, and gives you a framework to calculate whether Google Ads will be profitable for your specific situation before spending a dollar.

How Google Ads pricing works

Google Ads operates on a pay-per-click (PPC) model — you only pay when someone clicks your ad. You set a daily budget, bid on keywords, and Google shows your ad to people searching those terms. When they click, you're charged your cost-per-click (CPC).

The CPC you pay is determined by a real-time auction. Every time someone searches a keyword you're bidding on, Google runs an instant auction between all advertisers competing for that position. Your position (and cost) is determined by:

Your bid — the maximum you're willing to pay per click
Quality Score — Google's rating of your ad's relevance and expected click-through rate (1–10)
Ad Rank — bid × Quality Score × other factors (landing page experience, ad extensions)

A higher Quality Score means you pay less for the same position. A well-structured Google Ads campaign can outrank bigger competitors at a lower cost per click — this is why management quality matters enormously.

Wollongong Google Ads costs by industry (2026 benchmarks)

The following are typical cost ranges for Wollongong and the broader Illawarra market. Note that local CPCs are generally 20–40% lower than equivalent Sydney searches, which makes Google Ads particularly attractive for Illawarra businesses.

Industry	Typical CPC range	Monthly budget needed	Avg. job/sale value
Emergency plumbing	$8–$22	$1,500–$3,000	$350–$900
Electrician	$6–$18	$1,200–$2,500	$300–$800
Builder / Renovations	$5–$15	$1,500–$4,000	$15,000–$80,000
Landscaping	$3–$10	$800–$2,000	$1,000–$15,000
Dentist / Orthodontist	$8–$20	$2,000–$5,000	$300–$8,000
Physiotherapy	$4–$12	$1,000–$2,500	$90–$150/session
Legal services	$15–$60+	$3,000–$8,000	$2,000–$50,000+
Accountant / Bookkeeper	$6–$18	$1,500–$3,500	$500–$5,000/yr
Restaurant / Café	$0.50–$2	Usually not recommended	$25–$80
Retail (physical store)	$0.80–$3	$1,000–$3,000	$30–$200
Real estate agent	$8–$25	$2,000–$5,000	$8,000–$25,000+
Removalists	$5–$14	$1,000–$2,500	$500–$2,500

💡 Why tradies and professional services do so well

The industries with the best Google Ads ROI are those with high job values and transactional intent keywords. A plumber paying $18 per click who converts 10% of clicks to enquiries pays $180 per lead. If that lead books a $600 job with a 50% close rate, that's $360 revenue per $180 spend — a 2x return on ad spend before even considering repeat business or referrals.

What's the minimum viable budget?

For most Wollongong service businesses, we recommend a minimum of $1,000–$1,500/month in ad spend to generate enough click volume to optimise your campaigns meaningfully. Below that threshold, you get so few clicks per month that the data is too thin to draw conclusions or make smart adjustments.

That said, for high-CPC industries (legal, emergency trades), you may need $2,000–$3,000/month to get a sufficient number of leads to evaluate performance accurately.

⚠ The "set and forget" trap

Running Google Ads with a $500/month budget and no ongoing management is almost always money wasted. You'll burn through budget on irrelevant searches, never build Quality Score, and wonder why it doesn't work. Either commit to proper management or don't run Google Ads at all.

What drives your cost per click up or down

Keyword competitiveness

The more advertisers bidding on a keyword, the higher the CPC. "Emergency plumber Wollongong" is searched by someone with urgent, high intent — every plumber wants to be there, so the price is high. "Bathroom renovation Wollongong" has lower urgency, fewer emergency competitors, and a lower CPC despite a potentially much higher job value.

Quality Score

Quality Score (1–10) is Google's assessment of how relevant and useful your ad and landing page are to the searcher. A Quality Score of 8 vs 4 on the same keyword can cut your effective CPC in half. Improving Quality Score is one of the highest-leverage things a good Google Ads manager does.

Time of day and day of week

Demand (and therefore CPCs) fluctuate throughout the day. Emergency trade searches spike in the morning and after hours. Business service searches peak Tuesday–Thursday. Smart bidding strategies adjust bids automatically based on when your conversions are most likely — but this requires conversion tracking to be set up correctly.

Geographic targeting

Wollongong-specific targeting reduces wasted spend on people outside your service area. If you service Wollongong to Kiama, don't pay for clicks from Canberra. Tight geographic targeting also often lowers CPCs because there are fewer local advertisers than in broad metro markets.

Match types

Broad match keywords will match searches far outside your service offering. A plumber using broad match on "plumber" might appear for "plumbing apprenticeship courses" — a completely irrelevant search. Using phrase match and exact match on specific, high-intent keywords keeps costs down and conversion rates up.

What about Google Ads management fees?

On top of your ad spend, if you hire an agency or freelancer to manage your campaigns, expect to pay:

Agency management fees: typically $600–$1,500/month for a Wollongong small business campaign, or 10–20% of ad spend (whichever is higher) for larger budgets
Setup/onboarding fee: $500–$2,000 one-off for campaign build, conversion tracking setup, keyword research, and ad copy writing
Freelancer rates: $300–$700/month for lighter management, though this often means less frequent optimisation

Total cost of ownership for a typical Wollongong small business running Google Ads: $1,800–$4,500/month including ad spend and management. For most service businesses with decent job values, this is very achievable ROI if campaigns are managed well.

🎯 What good management looks like

A good Google Ads manager should be reviewing search term reports weekly (adding negative keywords), testing new ad copy, improving landing pages, monitoring Quality Scores, and adjusting bids based on time-of-day and device performance. If your manager only checks in monthly, you're overpaying for underperformance.

How to calculate if Google Ads will be profitable for you

Here's the framework we use with every Wollongong client before recommending Google Ads:

Average job/sale value — what does a typical customer spend with you?
Gross margin — after costs, what's left? (e.g. a $600 plumbing job with 40% margin = $240 gross profit)
Close rate — what % of enquiries turn into booked jobs? (industry average: 30–60%)
Website conversion rate — what % of visitors become enquiries? (good landing page: 8–15%)
Target CPC — what industry are you in? (use the table above)

Example calculation for a Wollongong electrician:

Average job value: $550 | Gross margin: 45% | Gross profit: $247
Close rate: 50% → need 2 enquiries per job → profit per enquiry = $123
Landing page conversion rate: 10% → need 20 clicks per enquiry
CPC estimate: $12 → cost per enquiry = $240
Cost per booked job = $480
Gross profit per job = $247 → Negative ROI at $12 CPC with these numbers

The fix? Either improve the landing page conversion rate to 15%+ (brings cost per enquiry to $160), improve the close rate, increase average job value, or focus on upsells and repeat business lifetime value. This is exactly the kind of analysis that separates profitable Google Ads from burning money.

When Google Ads isn't the right move

Google Ads isn't the right channel for every Wollongong business:

Low-margin products/services — if you sell $40 products with 25% margin, the maths rarely work
No website or a poor-converting site — sending paid traffic to a bad website doubles your losses. Fix the site first
No conversion tracking — if you can't measure cost per lead, you can't optimise. Don't spend money blind
No capacity to handle more leads — many tradies are already booked out. In that case, Local SEO that builds passive visibility is a better investment
Awareness-stage purchase — if customers don't know they need what you sell yet, search doesn't capture that demand. Social ads work better here

Frequently asked questions

How quickly will I see results from Google Ads?

Unlike SEO, Google Ads can generate leads from day one. Your ads go live as soon as your campaign is approved (usually within hours). The first 30 days are a learning phase — expect higher CPCs and lower conversion rates while the algorithm learns. Month 2–3 is typically when campaigns hit their stride.

Can I run Google Ads myself?

Yes, and Google makes it easy to get started. The danger is that it's also easy to waste money through broad match keywords, low Quality Scores, and no conversion tracking. Self-managed campaigns often spend 30–50% more per lead than well-managed professional campaigns. If you want to try it yourself, at minimum: use phrase/exact match, set up conversion tracking, review search terms weekly, and add negative keywords constantly.

What's the difference between Google Ads and Google Maps (Local SEO)?

Google Ads puts you at the top of search results as paid ads. Local SEO earns you a position in the Google Maps 3-pack and organic results for free — but takes 3–6 months to build. Most Wollongong businesses benefit from doing both: Ads for immediate leads while SEO compounds over time.

Is there a contract for Google Ads management?

At Wollongong Web Design Co, we work month-to-month. We don't believe in locking clients into 12-month contracts — if we're doing a good job, you'll stay. We recommend a minimum 3-month commitment to give campaigns time to optimise, but that's guidance rather than a contractual obligation.
