Start with the thing no Australian agency puts on its pricing page, because it decides how you read every SEO cost quoted below.
There is no independent survey of SEO pricing in Australia. None.
Every AUD figure you have been quoted, including the ones in this article, traces back to an agency publishing its own rate card.
The real survey data in this field is global, mostly American, and denominated in US dollars.
That is not a reason to ignore the numbers.
It is a reason to know which ones were measured and which ones were asserted, because those two categories get mixed together constantly and the mixing usually happens in the direction that suits whoever is quoting.
Here is the honest version, sorted by how much weight it can carry.
What the Surveyed SEO Cost Data Says
Two surveys are worth anything.
Both are in US dollars.
Ahrefs polled SEO providers and published the results at ahrefs.com/blog/seo-pricing.
The headline says 439 respondents, though the page’s own meta description says 350, an inconsistency Ahrefs has never reconciled.
The charts date from 2023, so treat it as 2023 data regardless of the update stamp.
The averages: US$2,917 a month across all respondents, and US$1,557 a month for providers serving local markets specifically.
Agencies doing local work averaged US$1,819, freelancers US$1,150.
The most common single band was US$501 to US$1,000, at 20.4% of respondents, and 68.8% of everyone surveyed charged US$2,000 a month or less.
Average hourly rate was US$111.
Note the gap between the headline average and the local average.
Local SEO is cheaper than national or ecommerce work by roughly half, and a dental practice competing across three suburbs is local work.
Backlinko surveyed over 300 SEO professionals at backlinko.com/seo-pricing, last updated December 2025.
It lands on US$1,000 to US$2,500 a month as typical, with a regional split worth knowing: retainers under US$500 a month are held by only 7% of providers in the US, UK and Australia, against 42% in India and Latin America.
If you are being quoted AU$400 a month, you have been quoted an offshore team, whether or not the invoice says so.
The Number That Decides Your SEO Cost
Every survey above reports dollars.
Only one reports hours, and hours is the number that tells you what you are buying.
From the same Backlinko survey, monthly retainers converted into work delivered:
| Monthly retainer (USD) | Hours of work per month |
|—|—|
| Up to $500 | 5 to 10 |
| $501 to $1,000 | 10 to 20 |
| $1,001 to $2,500 | 20 to 40 |
| $2,501 to $5,000 | 40 to 80 |
Sit with the top row.
A $500 retainer buys somewhere between five and ten hours a month.
That is one working day, spread across strategy, execution, and the reporting you receive.
Now think about what a dental practice needs done.
A technical crawl and fix pass.
Writing or rewriting a treatment page properly.
Managing the Google Business Profile.
Building or earning a link.
Watching rankings across several suburbs.
Producing a report a practice owner can read.
On one day a month, most of that day goes to the report.
This reframes the whole question.
“Is $800 a month reasonable for SEO?” has no answer.
“Is sixteen hours a month enough to do the things on this list?” has an obvious one, and you can answer it yourself without knowing anything about search.
Ask any provider quoting you how many hours the retainer represents and who does them.
The answers, or the reluctance to give them, will tell you more than the proposal deck.
The SEO Cost Australian Agencies Publish
Self-declared, unaudited, and worth knowing anyway because the convergence is interesting.
StudioHawk, December 2025, in AUD: entry-level retainers $500 to $1,000 a month, a growth band of $1,500 to $3,000 described as where most small and medium businesses see traction, and $5,000 or more for competitive work.
Consulting at $150 to $300 an hour.
A full site audit at $2,000 to $5,000.
First Page, January 2026, in AUD: $1,000 to $2,500 a month for small business and local, $2,500 to $5,000 for more competitive work, $5,000 to $15,000 and up for enterprise.
Consulting at $100 to $250 an hour.
Dental-specific, and closer to what a practice would be quoted: Digital Nomads HQ publishes dental SEO from $1,197 a month for a single-location clinic, and $3,000 or more for multi-location groups.
Three independent agencies with different positioning land on roughly the same place: AU$1,500 to $3,000 a month is where meaningful work starts for a local business, and $100 to $300 an hour for consulting.
That agreement means something even though none of it is surveyed.
It is also consistent with the Backlinko hours table once you convert.
The SEO Cost Number to Hold It Against
If a retainer feels expensive, compare it to the alternative rather than to zero.
First Page puts an in-house SEO specialist’s salary at AU$70,000 to $120,000, and the fully loaded cost at AU$100,000 to $150,000 a year once on-costs are included.
That is AU$8,000 to $12,500 a month for one person who takes annual leave, needs tools, and will not be equally strong at technical work, content and links.
Most practices are not choosing between an agency and a hire.
But the comparison sets a ceiling on what “expensive” can reasonably mean, and it explains why a $3,000 retainer covering several specialists is not obviously worse value than it looks.
What a Cheap SEO Cost Correlates With
Backlinko’s SEO Services Report carries a 2026 date, but read the fine print: the survey was designed and run with Northstar Research Partners and the underlying data is from 2019.
Cite it as 2019 data.
It is still the only real client-satisfaction dataset in the field.
Clients spending under US$500 a month were 75% more likely to be dissatisfied.
Clients spending over US$500 a month were 53.3% more likely to be extremely satisfied.
The rest of that survey is bleak reading for the industry, and I think practice owners should see it.
Only 30% of respondents would recommend their current SEO provider.
The industry’s net promoter score came out at zero.
Sixty-five percent had worked with more than one provider, 25% with three or more.
Of those who left, 82% cited dissatisfaction with results and 81% cited cost.
One finding cuts against the agencies-are-the-problem reading, though.
Among dissatisfied clients, 50% said they needed more training to benefit from SEO, 28% did not have the staff resources, 27% found it confusing, and 25% were not sure what they were paying for.
That last one is a briefing failure as much as a delivery failure, and it is fixable from your side.
If you cannot explain what your provider did last month, ask before you cancel.
If they cannot explain it either, then cancel.
How long before anything happens
The most authoritative statement on this comes from Google, and it is nine years old.
Maile Ohye, then a Developer Programs Tech Lead at Google, said in a February 2017 Search Central video on hiring an SEO: “In most cases, the SEO will need four months to a year to help your business first implement improvements and then see the potential benefit.”
That figure has since disappeared from Google’s live documentation.
I checked.
It is still the closest thing to an authoritative timeline that exists, so cite it as a 2017 video rather than current guidance, and treat anyone quoting a faster number as making it up.
There is one dataset on break-even worth mentioning, with heavy caveats.
First Page Sage publishes break-even times by industry and by service type from its own client campaigns, Q1 2021 to Q3 2025.
The service-type table is the useful part:
- Technical SEO only: break-even at 6 months
- Basic content marketing, around four average blog posts a month: break-even at 15 months, with a return on ad spend of 1.05
- Thought leadership and generative engine optimisation, around eight high-quality pages a month: break-even at 9 months
That middle row deserves attention from anyone being sold a content package.
Four mediocre posts a month is the most commonly sold SEO deliverable in Australia and it is, on this agency’s own numbers, close to break-even at best over more than a year.
Two caveats that matter.
First, this is an agency reporting on its own clients, whose campaigns it says typically cost around US$120,000 a year and skew heavily B2B.
Second, and worth stating plainly because it is repeated everywhere: the widely circulated “healthcare: 532% ROI, 11 months to break even” figure attributed to this report is not in it.
There is no healthcare row in the current table.
Someone invented it and everyone copied it.
The comparison worth making: paid versus organic
Dentistry is one of the most expensive keyword sets in advertising, which changes the maths on organic work.
WordStream’s 2025 Google Ads Benchmarks, drawn from campaigns running April 2024 to March 2025, puts dentists and dental services at an average cost per click of US$7.85 against a cross-industry average of US$5.26.
Average conversion rate 9.08%, giving an average cost per lead of US$83.93.
Dentistry ties home improvement for the highest cost per click in the report.
That data is US-weighted, and I am not going to convert it into Australian dollars and pretend it transfers.
Two Australian agencies publish AUD dental click costs that disagree with each other by a factor of two to three, neither states a dataset, and one of them quotes a US figure from 2024 as though it were an Australian figure from 2026.
Use the WordStream numbers as a benchmark with a US label attached, and get your real number from your own Google Ads account.
The structural point survives the currency question.
At roughly $84 a lead, a practice running paid search spends the cost of a mid-range monthly retainer on about thirty leads, every month, forever, and stops receiving anything the day the card declines.
Organic work compounds and takes most of a year to arrive.
Neither is better.
They fail in different ways, and most practices should run both, which is one reason a provider who only sells you one is worth a second look.
SEO Cost Figures I Could Not Verify
Publishing this list because the alternative is repeating them.
“Clutch: average monthly SEO spend is $3,199.” Quoted across dozens of agency blogs.
I could not locate any Clutch publication containing it.
“SEO delivers 22:1 ROI.” Traces to aggregator blogs citing each other.
No primary research behind it.
“Healthcare SEO: 532% ROI, 11-month break-even.” Attributed to First Page Sage.
Not in their current table.
Australian dental cost-per-click figures. Two AU agencies publish ranges ($8 to $15 and $10 to $30 a click for comparable terms).
Neither discloses a dataset.
If a proposal quotes any of these at you, it is not a sign of dishonesty.
It is a sign that nobody checked.
Which is roughly the same problem the penalty figure in AHPRA advertising guidance has, and it tends to be the same providers.
What to Ask About SEO Cost Before You Sign
Google publishes its own advice on this at Do you need an SEO?, last updated June 2026, and it is more direct than most agencies would like:
No one can guarantee a #1 ranking on Google. Beware of SEOs that claim to guarantee rankings, allege a ‘special relationship’ with Google, or advertise a ‘priority submit’.
And on audits specifically:
An SEO audit should be about giving you realistic estimates of improvement… If they guarantee you that their changes will give you first place in search results, find someone else.
Google also advises granting only read access to Search Console during an audit, not write access.
Worth remembering, because the request usually arrives as a formality.
Beyond that, four questions that produce useful answers:
How many hours a month does this retainer represent, and who performs them?
Compare against the table above.
What happens to the work if we stop?
Pages, links and profile improvements you own stay with you.
If the answer is that everything reverts, you were renting rankings.
What will you not do?
A provider who will not name anything they consider out of scope has not thought about scope.
Who writes the copy, and who checks it against AHPRA?
For a health practice this is not optional, and the liability sits with you rather than the agency.
Covered in more detail in the AHPRA advertising piece.
Where Our SEO Cost Sits
For the sake of not being coy about it: we sell a fixed-price audit at US$350.
That is deliberately below the AU$2,000 to $5,000 band that StudioHawk and First Page quote for a full site audit, and below the cheapest project tier in either survey above.
It is priced that way because an audit should be a decision, not a commitment.
You get the findings and the fix list, and you can hand them to your existing provider, action them in-house, or do nothing.
If you then want the work done, we scope that separately.
What we will not do is quote you a monthly figure before anyone has looked at the site, which is the part of this industry that generates most of those Backlinko satisfaction numbers.

Common questions
How much does SEO cost in Australia per month?
Australian agencies publish entry retainers around AU$500 to $1,000, a working band of AU$1,500 to $3,000 for local businesses, and AU$5,000 or more for competitive markets.
None of those figures come from an independent survey.
The surveyed global data puts local SEO at an average of US$1,557 a month.
Is cheap SEO worth trying?
A retainer under US$500 buys five to ten hours of work a month, and 2019 survey data found clients at that level were 75% more likely to be dissatisfied.
It is not that cheap providers are dishonest.
It is that one day a month does not cover the work.
How much should an SEO audit cost?
Australian agencies quote AU$2,000 to $5,000 for a full audit.
Global survey data puts the most common project fee at US$2,501 to $5,000.
Cheaper audits exist, including ours, and the thing to check is whether you receive prioritised findings or an automated tool export with a logo on it.
How long until SEO works?
Google’s own guidance, from a 2017 video, is four months to a year.
Nobody credible publishes a shorter figure.
Should a dental practice do SEO or Google Ads?
Dentistry has among the highest cost per click of any industry, so paid search is expensive and immediate while organic is slower and compounds.
Most practices benefit from both.
A provider selling you only one is worth questioning about why.
How do I know if I am being overcharged?
Convert the retainer to hours and compare it to what you have been promised.
Then ask what happens if you stop paying.
Why does one agency quote $500 a month and another $5,000 for the same thing?
Because the retainer buys hours, and the two proposals are not for the same number of them.
At the surveyed rates $500 is five to ten hours a month and $5,000 is forty to eighty.
Ask both providers for the hours and who performs them, and the gap stops being mysterious.
Is $500 a month enough for SEO for a dental practice?
It buys roughly one working day a month, including the time spent producing your report.
Set that against a technical fix pass, a treatment page rewritten properly, the Google Business Profile, earning a link and tracking rankings across several suburbs, and the answer is visible without knowing anything about search.
Is an SEO agency charging AU$400 a month using an offshore team?
Almost certainly.
Backlinko’s survey found retainers under US$500 a month held by 7% of providers in the US, UK and Australia against 42% in India and Latin America.
The work may still be competent.
What is not honest is a local rate card that does not say where the work happens.
Should we pay for SEO monthly or buy a one-off audit first?
An audit tells you what is wrong before you commit to a retainer, and it is the cheaper way to find out whether the retainer is needed at all.
It is also the only part of this that produces a deliverable you keep if you walk away.
How long before we see any return on SEO spend?
Google’s own guidance has long put it at four to twelve months from starting work to seeing benefit, and that is the figure to plan against.
Anyone quoting weeks is either describing paid ads or describing something that will not last.
Is Google Ads cheaper than SEO for a dental practice?
They behave differently rather than one being cheaper.
Ads buy visibility that stops the day you stop paying, and the cost per click is set by whoever else is bidding.
Search work compounds and survives a pause, but it takes months to start and can be lost to a competitor who works harder.
Most practices at some point run both.
Do we still own anything if we stop paying our SEO agency?
Ask before you sign.
Content published on your own site and fixes made to it stay with you.
Rented links, a landing page hosted on the agency’s domain and a tracking number pointed at their system do not.
The answer to this question tells you more about a provider than their pricing does.
