Ask an agency about SEO cost per month and you’ll usually get a number with very little said about what it buys. That’s the part worth understanding before you sign anything. Our monthly SEO covers technical fixes, keyword and page work, new content, links and a report every month, so this guide walks through each of those, what decides the fee, and the costs that sit outside it. It won’t give you a price list, because the honest answer depends on your site and your competitors.
The short answer
SEO cost per month in Australia depends on three things: how much work your site needs, how competitive your searches are, and how much new content and link building the plan includes. A monthly fee should buy real work you can see in a report: technical and speed fixes, keyword research and page improvements, new content, links from other sites, and results tracked in Google Search Console and Analytics. Some costs usually sit outside the fee, such as a one-off audit, extra copywriting, or development work on your site. Google’s own guidance says no one can guarantee a number-one ranking, so treat any guarantee as a warning sign. Our advice from running monthly SEO is to judge a quote by what gets done each month and how results are reported, not by the headline number, and to expect several months before the work shows in Google.
What your SEO cost per month should pay for
“SEO” covers very different amounts of work, which is why two quotes for the same site can look nothing alike. A monthly plan worth paying for includes some mix of these five things. Ours includes all five.
Technical and speed fixes
Google has to be able to find, read and load your pages before anything else matters. That means fixing pages that can’t be indexed, broken links, slow load times on phones, missing redirects and duplicate pages. On an older site this work is heavy in the first months and lighter after that.
Keyword research and on-page work
Every important page should target one main search, and no two pages should compete for the same one. We map that out first, then improve titles, headings and page copy so each page clearly answers the search it’s meant to win. It’s the least glamorous part of SEO and often the one that moves results first.
New content
Pages and articles that answer what your customers actually type into Google, such as prices, comparisons and how-to questions. Content is where most of the monthly effort goes on a growing site, and it’s worth asking who writes it. Ours is written by our own copywriting team.
Links and digital PR
Links from other relevant websites still tell Google your site is worth trusting. Good link building means earning them: directory and industry listings, partners, suppliers, and stories other sites want to cite. Google’s spam policies treat buying or selling links for ranking purposes as link spam, so a cheap “100 backlinks” package can do real harm.
Reporting
Each month you should see what was done and what changed: clicks, impressions and positions from Google Search Console, and enquiries from Google Analytics. Our tools are Semrush, Ahrefs, Search Console, GA4 and Rank Math, and the Search Console and Analytics accounts belong to you.
What decides the fee
Most of the difference in SEO cost per month comes down to these factors:
- How competitive your searches are. A Brisbane plumber chasing “plumber Brisbane” is up against dozens of established sites. The same plumber targeting a specific service in a smaller suburb faces far fewer.
- The state of your website. A slow site with technical problems needs fixing before new content can do much.
- How much content and link building you want each month. This is the biggest lever on the fee and on how fast results come.
- How many services and locations you target. Each one needs its own pages and its own work.
- Who makes the changes. If your developer has to action every fix, allow for their time too.
Monthly plan, one-off audit or hourly?
SEO is sold in a few different ways. None is right for everyone.
| Model | What you get | Good for |
|---|---|---|
| Monthly plan | Ongoing technical, content and link work with a monthly report | Businesses that want steady growth from Google |
| One-off audit | A full check of your site with a prioritised list of fixes | Finding out what’s wrong before you commit, or handing the list to your own team |
| Set-up project | A defined job, such as a Google Business Profile or the SEO for a new website | A launch, or one specific gap |
| Hourly advice | Time with a specialist to answer questions or review work | Businesses with someone in-house doing the work |
We offer monthly SEO with a three-month minimum, then month to month, plus a one-off SEO audit and Google Business Profile setup for businesses that just need those.
Costs outside the monthly fee
Some of what your SEO needs may not be in the quoted SEO cost per month. Ask about each of these before you sign:
- Extra content: more pages or articles than the plan includes.
- Development work: changes to your site’s code or design that the SEO work recommends.
- Paid tools: professional tools such as Semrush and Ahrefs are subscriptions. Ask whether they’re included.
- Google Ads: ads are a separate cost from SEO, paid to Google. Our guide to what Google Ads cost per month explains how that spend works.
Two things you shouldn’t pay for: a Google Business Profile, which is free to create and manage, and Google Search Console, which is also free. You may pay someone to set them up well, but not for the accounts themselves.
How to judge an SEO quote
Google publishes its own advice on hiring an SEO. It suggests asking to see examples of previous work, whether they follow Google Search Essentials, what results they expect and in what timeframe, what experience they have in your industry and location, and how you’ll communicate. When you compare SEO cost per month between providers, we’d add three more questions:
- What exactly happens in the first three months?
- Will the Search Console, Analytics and Business Profile accounts be in my name?
- What does the monthly report show, and can I see an example?
Walk away if you hear any of these:
- A guaranteed number-one ranking. Google says plainly that no one can guarantee a #1 ranking.
- Secret methods or a “special relationship” with Google. There isn’t one.
- Bulk link packages. Bought links break Google’s spam policies.
- Reports without access. If you can’t see the data in your own accounts, you can’t check the claims.
What results to expect, and when
SEO is slow at the start. Google’s SEO starter guide says some changes take effect in a few hours and others take several months, and that you’ll usually want to wait a few weeks before judging whether a change worked. Specific searches tend to move first, and competitive ones take longer. We cover the stages in detail in how long SEO takes to work.
For a real example, PublorAI, an AI blog our team handles the SEO for, earned 63.8K impressions and 886 clicks from Google in the three months to 26 September 2026. That’s the kind of steady, measurable growth your SEO cost per month should show in its reports.
Frequently asked questions
Is SEO worth it for a small business?
It usually is if people search for what you sell and your customers come from a defined area. SEO takes months to build, but the visitors it brings don’t stop when a budget runs out, unlike ads. If you need enquiries next week, ads are the faster option and SEO is the longer-term one.
Can I do SEO myself?
You can do the basics yourself: a clear page for each service, good titles and descriptions, a Google Business Profile, and Search Console set up. Google’s SEO starter guide is a free, reliable place to start. Many businesses bring in help once content and link building need more time than they have.
Why does SEO cost per month vary so much between agencies?
Because the work included varies. One quote may cover a monthly report and a few small fixes; another may include new content, link building and technical work every month. Compare what’s done each month, not just the fee.
How long is a typical SEO contract?
It varies by provider, so ask before you sign. Ours is a three-month minimum, then month to month, because SEO needs a few months to show results but you shouldn’t be locked in after that.
Is a Google Business Profile free?
Yes. Creating and managing a Google Business Profile is free. You need a Google account and an eligible business, and you may choose to pay someone to set it up and keep it active, but Google doesn’t charge for the profile.
Does SEO include Google Ads?
No. SEO works on your free listings in Google; Google Ads are paid placements, charged by Google for clicks. Many businesses run both, and with us the ad spend is always paid to Google directly, so it’s never part of your SEO cost per month.
Final thoughts
A fair SEO cost per month buys work you can see: fixes, content, links and honest reports from accounts you own. Ask what happens each month, check the provider against Google’s own questions, and give the plan a few months before you judge it. If you’d like a plan for your business, see how our monthly SEO works or send us your website. We reply the same business day, Brisbane time, with what we’d do first.
This guide is general information, not financial advice. What SEO costs and achieves depends on your website, your market and the provider, and no one can guarantee rankings. Always get a written proposal that lists the monthly work before you commit.
