How much does SEO actually cost in Australia?

Ask ten agencies what SEO costs and you’ll get ten different answers, most of them deliberately vague until you’re on a sales call. We’d rather just tell you.

The short version, in dollars

For ongoing SEO on a monthly retainer, most Australian businesses pay somewhere between $1,500 and $5,000 a month. The average for a small-to-mid-sized business sits around $2,500 to $3,500. Below about $1,000 a month you’re usually buying someone’s spare time and a bit of automated reporting, not a strategy. Above $5,000 you’re into competitive, national-scale campaigns with serious content and authority-building behind them.

One-off audits are different. A solid technical SEO audit runs roughly $1,500 to $3,500, and a deep audit of a large e-commerce site with thousands of pages can be more, simply because there’s more to crawl, analyse and untangle.

What you’re actually paying for

The more useful question isn’t “what does it cost” but “what am I actually paying for.” A real retainer buys skilled hours across three fronts: technical work on the site itself, content that targets how your customers search, and the slow accumulation of authority. Month to month that looks like fixes shipped, pages published, links earned and a report that ties it to traffic and revenue — which is why our retainers are scoped exactly that way.

Cheap SEO is expensive, because the most common outcome is twelve months of invoices and no movement. Good SEO is a compounding investment: the work you pay for this quarter keeps returning long after, because rankings and authority don’t reset the way paid ads do.

A simple test for comparing quotes

Here’s a simple test when you’re comparing quotes. Ask exactly what gets done each month, who does it, and how success is measured. A real answer sounds like “technical fixes, this many content pieces, link acquisition, and a monthly report tied to organic traffic and revenue.” A bad answer sounds like “ongoing optimisation” with no specifics. Vagueness in the pitch becomes vagueness in the results.

The same scrutiny applies to the person selling it — we’ve written a field guide to the red flags when hiring an SEO agency, and price is only one of them.

When to start with an audit instead

If you’re not ready for a retainer, don’t start with one. Start with a one-off technical audit. It’s a bounded cost, it tells you exactly what’s broken and in what order to fix it, and it makes any retainer you buy afterwards — from us or anyone — dramatically more effective, because the foundation work is identified up front. It’s also the cheapest way to find out whether an agency actually knows what it’s doing before you commit to a year of invoices.

Price matters, but it’s the cheapest part of the decision. The expensive part is the year you lose if you choose wrong.
