The short answer
Most Perth businesses can expect SEO services to start from around $997 per month for a focused, traditional search engine optimisation retainer aimed at Google and Bing. To also be visible in AI search engines like ChatGPT and Claude, SEO packages adding that generative engine optimisation layer start from around $1,997 per month.

Those are starting points, not the whole story. There is no single average SEO cost in Australia, and SEO pricing models vary too. Monthly retainers are the standard for ongoing SEO work, project based pricing suits once off SEO projects like an SEO audit, and some SEO consultants charge an hourly rate. What you pay depends on a handful of real factors, walked through honestly below, so you can work out the right SEO investment rather than guess at an exact cost.
What actually drives the cost of SEO
Search engine optimisation is not one fixed product, so SEO pricing moves with the work. Five things make the biggest difference.
How competitive your market is. Ranking a local business for a niche service is very different from fighting a competitive industry, which demands more resources to earn and hold visibility in search results.
The condition of your site. A fast, clean site needs less remedial technical SEO than a large one with technical problems, thin content or a messy history.
The scope. A plumbing business targeting a few suburbs costs less than an e-commerce SEO campaign or national push, with multiple locations higher again.
How quickly you want results. Quality SEO consumes serious hours monthly, and a faster pace means more of them.
How much content is needed. If your site needs new pages and ongoing content creation, that production is part of the cost.
What good SEO services include
Price only means something next to what you get. A genuine retainer should cover comprehensive SEO strategies, not one slice.
Technical SEO, so search and AI engines can crawl, read and trust your site.
On page optimisation, shaping content, internal linking and structure around real keyword research into what customers search for.
Local SEO, including Google Business Profile optimisation and consistent local business listings, so you show up in Google Search and Google Maps.
Link building, earning good quality links and mentions that tell search engines you are credible.
Clear reporting, in plain English, tied to leads and revenue rather than vanity numbers.
If an SEO proposal looks cheap, ask which of these is missing. Usually something is.
Traditional SEO or SEO plus AI search
People are not just searching Google anymore. Search is splitting in two, and our SEO plans reflect that.
SEO only, from $997 per month. This focuses on traditional search engine results on Google and Bing, the right choice if your customers still find you mainly through classic search, which for many small businesses they do.
SEO plus AI, from $1,997 per month. This includes all the SEO work and adds a dedicated layer for Google AI and AI search engines like ChatGPT and Claude. Our SEO team optimises for AI answers, monitors the prompts your customers and competitors use, and finds opportunities as those answers change.
Neither is better in the abstract. It depends whether your buyers have started asking AI assistants for recommendations in your category. If they have, the AI layer earns its keep. If not yet, strong traditional SEO keeps you ready. You can read more on our GEO service page.
Why the cheapest option usually costs more
Someone is always offering SEO for a couple of hundred dollars a month. At that price, the work tends to be automated, generic, or built on shortcuts like keyword stuffing that risk your rankings, often with hidden costs in the fine print. Many SEO clients come to us after paying cheap SEO companies that quietly did nothing, or worse, did damage that costs more to undo.
Quality SEO is a real service delivered by people who research, write, build and monitor, and it takes time to do well. Priced sensibly by a reputable agency, it is one of the highest return channels in digital marketing. Priced too cheaply, it is an expense with nothing to show for it.
What results to expect, and when
SEO is an investment that builds, not a switch you flip. Technical and local improvements produce earlier signals, but durable growth in rankings, website traffic and leads develops over several months, and the most competitive terms can take a year or more. The patience pays, because the first result in Google attracts the lion’s share of clicks.
To show what good SEO efforts can do, our clients see an average of 64 percent year on year growth in organic traffic and a 70 percent increase in qualified leads. One of them, Suit Vault, was ranking first for almost all of their keywords. Across more than 100 clients and seven years, the pattern is steady, compounding results rather than overnight spikes.
How to choose the right SEO budget
Simply put, your budget should match the value of the customers SEO can win you and your wider business goals. If a new client is worth thousands, a retainer that brings in a handful each month pays for itself many times over, often beating paid ads and social media marketing on cost per lead, for small and medium sized businesses alike. Work back from what a customer is worth to the level that lets your SEO strategy actually compete.
