How much does SEO cost in Australia?

SEO pricing in Australia is all over the map, partly because a lot of agencies are selling activity rather than results. You can pay $300 a month for someone to "do SEO" and have no idea whether any of it works. You can also pay $5,000 a month and get the same. The price isn't the signal. What they do for it is.

Let's break down what the money actually buys.

One-off audit and fix: $4,000-$8,000

If your site already exists and isn't ranking, start here, not with a retainer. An SEO audit is a one-time job. Someone crawls the whole site, finds what's holding it back, slow pages, broken internal links, thin or duplicate content, missing structured data, indexing problems, and gives you a prioritised list of fixes.

The "and fix" part matters. An audit that hands you a 40-page PDF and walks away is half a job. We audit and implement: the technical fixes, the on-page changes, the structured data, the content gaps. For most Australian small-to-mid businesses that's a $4,000-$8,000 piece of work, and it's often the single highest-return thing you can do for your site.

There's more on what a good audit covers in our guide to SEO audits.

Ongoing retainers: it depends, and that's honest

SEO isn't set and forget. Google changes, competitors move, and content needs to keep coming. A monthly retainer makes sense once the foundations are fixed, but only if you know what you're paying for.

A real retainer buys some mix of new content written and published, technical monitoring, link and authority building, and analytics work to track what's converting. What it should never buy is a recycled report showing "keywords moved up" with no link to enquiries or revenue.

We bundle SEO into ongoing retainers alongside ads and analytics monitoring, because in practice it's the same job: getting the right people to your site and turning them into customers. Those run $1,500-$3,000 a month, priced per business based on how much content and competition you're dealing with.

What separates good SEO from billable busywork

The honest tells aren't hard to read once you know them.

Good agencies tie work to outcomes. Rankings are a means, not the goal, so they report on enquiries and revenue, not just position changes.

They write real content. AI-generated filler doesn't rank in 2026. Google has gotten very good at spotting it, and so have your readers. Human-written, genuinely useful content is the thing that moves the needle.

They show their working. You should be able to see what was changed, when, and what happened next in the analytics.

And they don't lock you into 12 months on day one. Confidence in the work shows up as flexible terms.

Red flags worth walking away from

Be wary of anyone who guarantees a #1 ranking, because nobody controls Google's algorithm. Same goes for backlinks from spammy directories, or anyone who can't explain in plain English what they'll do this month. Cheap link-buying and content spinning can get a site penalised. That's paying to make things worse.

The short version

For most Australian businesses the smart sequence is simple. Pay $4,000-$8,000 once to audit and fix the site properly, see what that does to your traffic and enquiries, then decide whether an ongoing retainer is worth it. You'll be making that call with real data instead of a sales pitch.
