SEO prices vary enormously, from a few hundred dollars a month to tens of thousands. That range confuses buyers and makes it hard to tell a fair quote from a poor one. This lesson explains the common pricing models, what drives cost, what's typically included, and how to set a budget that makes commercial sense for your business.
Common pricing models
Monthly retainer
The most common model. You pay a fixed monthly fee for an agreed scope of ongoing work: technical monitoring, content, links and digital PR, local SEO, reporting and strategy. Retainers suit SEO because results come from consistent work over months.
Look for: a clear list of monthly deliverables or hours, what happens to unused hours, the minimum term, and the notice period.
Fixed-price project
A defined piece of work with a set price, such as:
- An SEO audit and prioritised recommendations.
- Site migration support (redirect mapping, pre- and post-launch checks).
- A keyword research and content plan.
- A set of new service or location pages.
Projects suit businesses with in-house capability that need expert input at specific points, or that want to test an agency before committing.
Hourly or day rate
Consultants often charge by the hour or day for advice, training or ad-hoc work. It's flexible and transparent, but costs can be harder to predict. Ask for estimates and caps.
Performance-based pricing
Payment tied to outcomes, such as rankings, traffic or leads. It sounds attractive but has pitfalls:
- Rankings-based deals can reward ranking for easy, low-value terms that bring no customers.
- Lead-based deals need careful definitions (what counts as a lead?) and tracking both sides agree on.
- Agencies may take shortcuts to hit targets, which can breach search engine guidelines and put your site at risk.
Some hybrid models (a base retainer plus a bonus for agreed business outcomes) can work well if the measures are meaningful and the methods are transparent.
Indicative price ranges
Prices differ by country, city, provider and scope, and change over time, so treat these as rough indications for the Australian market rather than benchmarks:
| Type of engagement | Indicative range (AUD, ex GST) |
|---|---|
| Small local business retainer | Roughly $800 – $2,500 per month |
| Established SME, competitive market | Roughly $2,500 – $7,500 per month |
| Large ecommerce or national brand | $7,500 to well over $20,000 per month |
| SEO audit (small to medium site) | Roughly $1,500 – $10,000 one-off |
| Migration support | Varies widely with site size; often several thousand dollars or more |
In the UK, US and New Zealand, ranges are broadly similar in local currency terms, with large cities and specialist consultancies at the top end. Very low prices, such as $199 a month for "complete SEO", usually mean little work is done, it's heavily automated, or it relies on risky tactics.
What drives cost
- Competition: ranking for "personal injury lawyer Sydney" needs far more work than "mobile dog grooming Toowoomba".
- Site size and complexity: a 20,000-product store has more technical and content work than a 15-page service site.
- Number of locations or markets: each city or country adds work, especially with different languages.
- Starting point: a site with penalties, technical debt or no content needs more upfront work.
- Scope of content and digital PR: original research, photography and outreach take time.
- Seniority: experienced strategists cost more than junior staff, and the mix matters.
- What you do in-house: if your team writes content or handles development, the agency costs less.
What's included, and what usually isn't
Typically included in a retainer (check each proposal):
- Strategy and planning.
- Technical audits, monitoring and recommendations.
- Content planning, writing or optimisation (quantity should be specified).
- Local SEO and Google Business Profile management.
- Link earning or digital PR activity.
- Monthly reporting and meetings.
Often not included:
- Development work to implement technical fixes, which may need your web developer.
- Third-party tool subscriptions, or they're included at a markup.
- Advertising spend, which is separate from SEO.
- Photography, video and design.
- Website rebuilds.
Ask for these to be spelled out, so you can compare like with like.
Ownership and contract terms
Before signing, confirm:
- You own your content, website, domain and accounts (Google Analytics, Search Console, Google Business Profile, ad accounts). If you leave, everything stays with you.
- Minimum term and notice period. Three- to six-month initial terms are common; twelve-month lock-ins with heavy exit fees deserve scrutiny.
- Who does the work. Is it the senior person who pitched, a junior team, or an offshore subcontractor? Outsourcing isn't necessarily bad, but you should know.
- Price changes and what happens if scope changes.
- Compliance with search engine guidelines, stated in writing.
In Australia, the unfair contract terms provisions of the Australian Consumer Law cover many small business contracts, and penalties now apply. Terms that let only one party cancel or change the price may be unfair. Seek advice if in doubt.
Setting a sensible budget
Work backwards from business value rather than picking a number:
- Average customer value: what is a new customer worth in gross profit, including repeat business?
- Conversion rates: roughly what share of website enquiries become customers?
- Realistic opportunity: how much additional search traffic or enquiries could you win, based on keyword demand and competitors?
- Payback period: SEO is an investment; most businesses should expect it to take months to pay back, then deliver ongoing returns.
Worked example: a Brisbane landscaping business
- Average project: $12,000, with about 30% gross margin, so roughly $3,600 gross profit.
- About one in four qualified enquiries becomes a project.
- A realistic goal is 8 extra organic enquiries a month after 9–12 months, so roughly 2 extra projects, about $7,200 gross profit monthly.
On those assumptions, a retainer of $2,000–$3,000 a month could pay back well once results build, while a $10,000 retainer probably wouldn't. The numbers are estimates, so revisit them with real data at six months.
Comparing quotes fairly
Three quotes for "SEO" can describe completely different work. To compare them, put each into the same simple table:
| Agency A | Agency B | Agency C | |
|---|---|---|---|
| Monthly fee (ex GST) | |||
| Setup or audit fee | |||
| Minimum term / notice | |||
| Senior strategist hours per month | |||
| Content pieces per month (and length/type) | |||
| Technical work included (and who implements) | |||
| Link earning / digital PR approach | |||
| Local SEO included? | |||
| Tools and reporting included? | |||
| Who does the work (in-house, subcontracted) | |||
| How success is measured |
Gaps in the table are questions to ask. A quote that can't be filled in clearly is a warning sign in itself.
Hidden costs to budget for
Even with a good agency, set aside money for:
- Developer time to implement technical recommendations, often a few hours to a few days a quarter.
- Your own time for approvals and expert input.
- Photography or video of your work, team and premises.
- Tools if you want your own access to keyword or rank-tracking data.
- Review and reputation tools, if you want to manage reviews at scale.
Paying for value, not activity
A long list of activities (50 directory submissions, 20 blog posts, 100 "backlinks") isn't the same as value. Ask how each activity links to the agreed business goals, and prefer fewer, better pieces of work, such as one genuinely useful cost guide over ten thin articles.
Key takeaways
- Common models: monthly retainer, fixed-price project, hourly or day rate, performance-based.
- Prices vary with competition, size, locations, starting point, content scope and seniority.
- Very cheap "complete SEO" usually means little work or risky tactics.
- Check what's included and excluded: development, tools and ad spend are often separate.
- Own your accounts and content, and check terms and notice periods.
- Set budgets from customer value and realistic opportunity, not a gut feel.
