How much does SEO cost in Australia? (2026)

Most Australian agencies charge between $1,500 and $5,000 a month for an SEO retainer, with hourly rates of about $80 to $250. Our own retainers start at $3,000 a month. Below, we explain what each level buys, how to tell whether it's paying off, and what to ask before you sign.

SEO (search engine optimisation) is the work that helps your website show up when people search on Google, and increasingly when they ask AI tools like ChatGPT.

What SEO costs in Australia

These ranges come from a review of pricing published by Australian agencies in October 2026. Figures are in Australian dollars and usually exclude GST.

Where BFJ Digital sits

Our SEO retainers start at $3,000 + GST a month. That covers technical fixes, new and improved pages, link building, and monthly reporting connected to your CRM. What's included depends on your site, your market and what you want to achieve, so we scope it on a call.

Two things to be wary of at any price. First, tactics designed to manipulate rankings rather than help people, such as buying links or publishing pages at scale that add nothing for the reader. Both are against Google's spam policies, and fixing a manual action against your site costs time, money and visibility. Second, promises of page-one rankings. No one controls Google's results, so no one can honestly guarantee them.

What drives the cost

Two businesses can get very different quotes for "SEO" and both can be fair. It usually comes down to five things.

How we measure whether SEO is paying off

Rankings and traffic are early signs. Revenue is the result. We connect enquiries and sales to their recorded sources, and flag the gaps.

1. Enquiries land in your CRM with their recorded source. When someone fills in a form, HubSpot records the first known source, such as organic search, and the page they landed on. Tracking has limits, such as cookie consent and people switching devices, so some enquiries arrive without a clear source.
2. That source stays with the deal through to the sale. When the enquiry becomes a deal and closes, the revenue sits against the channel recorded for it.
3. Online sales are tracked by channel. For eCommerce, GA4 (Google Analytics 4) records the channel for each sale it can attribute.
4. Gaps are flagged, not filled in. Phone calls are the common one. Where a call can't be linked to a source, we say so in the report rather than guess.

One limit applies to organic search in particular. Google Search Console reports organic keywords in aggregate, so no tool can tell you which exact organic keyword produced a specific lead. We report organic performance at the page and channel level instead, which is enough to decide where the next dollar goes.

As a HubSpot Diamond Partner, we set up the CRM side of this ourselves. Labs, our reporting platform, then brings Search Console, GA4, call tracking and HubSpot into one monthly report, so you see search, enquiries and revenue side by side. The work doesn't stop at launch. Each month we use what the data shows to decide what changes next.

What this looked like for Ainslie Bullion

Ainslie Bullion is a precious metals dealer we've worked with across SEO, paid media, CRM and analytics. Between FY2023/24 and FY2025/26:

• Organic search revenue grew 10.1 times.
• Sales referred by AI assistants, such as ChatGPT, now show up as their own channel in GA4.

That's what the data shows. Here's how we read it. Gold prices rose over the same period, which lifted revenue across Ainslie's business, so not all of that growth is down to SEO. What we can say is that organic search grew strongly over two years, and AI assistants have appeared as a new source of sales worth watching.

Is it worth it? A worked example

This example is illustrative. Swap in your own numbers. Count only the additional enquiries the SEO work brings in, not business that would have found you anyway.

Year one is usually lower, because results build over months. If clients keep buying from you for years, the return grows over time, but judge payback over the same period you're paying for the work.

SEO now includes AI answers

More buyers now ask ChatGPT, Gemini or Perplexity before they search Google. These tools name a few businesses in their answers. If yours isn't one of them, you've missed that buyer early.

We track how often AI tools mention our clients in Labs. We focus on questions that don't already include the business name, because being recommended to a new buyer matters more than being found by someone who already knows you. Ask any SEO partner how they measure this.

Six questions to ask before you sign

1. What will you change in the first 90 days, and why those things first?
2. How will I see which pages and channels bring in enquiries and revenue, not just visits?
3. What happens after the work goes live? Who checks it's still working in month six?
4. How do you track whether AI tools mention my business?
5. Who actually does the work, and who do I talk to?
6. Can I see a real report you've sent a client, with the names removed?

If the answers are vague, the reporting probably will be too.

Common questions

How long does SEO take to work? Usually months rather than weeks. Technical fixes can show early movement. Content and authority take longer to build. A good partner shows you the early signs, like impressions and positions moving, well before enquiries pick up.

Is SEO worth it for a small business? It can be, if the searches you target are ones your customers actually make. A local service business often gets more from a handful of strong suburb and service pages than from chasing broad, competitive terms.

Do I need SEO and Google Ads? Not always, but they work well together. Ads bring in enquiries now. SEO builds a source of enquiries you don't pay for per click. Ad data also shows which searches convert, which helps decide where SEO effort goes.

Can I do SEO myself? Some of it, yes. Keeping your Google Business Profile current and writing clear service pages makes a real difference. Technical fixes and measurement are where most businesses need help.

Your next step

If your current SEO report shows rankings but can't show which enquiries and sales came from search, that's worth asking about.

There are two ways to start:

• Run our free 4-minute website check. It's an automated scan that shows technical and on-page issues straight away. It's a quick health check, not a full strategy audit. Ask us to run it.
• Request a scoped SEO proposal. We'll review your site, your CRM data and your market, then quote against what you want to achieve. Request a proposal.
