How much should a small business spend on SEO each month?

SEO is not a product you buy once. It is a monthly budget against a moving target, because competitors keep publishing, Google keeps changing how results are assembled, and your own site keeps ageing. That makes the useful question “what can I keep spending while this compounds?” rather than “what is the cheapest package?”

Two businesses in the same town can need very different budgets. A plumber chasing three suburbs is fighting a handful of local competitors. A retailer chasing national keywords is fighting established brands with content teams. The number should follow the market, not a template.

What SEO actually costs in Australia

Published 2026 Australian estimates put most monthly SEO retainers between $1,000 and $5,000, with small local campaigns often below that and competitive national programs above it. Hourly consultants commonly charge $100–$250 an hour. Project work — an audit, a migration, a local setup — ranges from a few hundred dollars to five figures depending on scope.

Ranges combine current published Australian estimates from Caffeinate Digital and What’s The Damage? with the models buyers commonly encounter. They are advertised examples, not an official price list, and the right number depends on your market.

What the budget should actually buy

• Technical health. Crawlability, speed, mobile performance, indexing and structured data. This is usually heaviest in the first months.
• Useful content. Pages that answer what customers actually search, written for people rather than keyword counters.
• Local visibility. An accurate Google Business Profile, consistent details, genuine reviews and real service-area information.
• Earned mentions. Legitimate links and references from organisations that matter in your industry. Bought link bundles are a liability.
• Reporting tied to enquiries. Calls, forms and bookings, not a chart of impressions that never turns into work.

A smaller budget means fewer of these run at once. That is fine, provided you and the provider agree on the order. A larger budget that spreads thinly across all five is worse than a small budget that fixes one properly.

A simple way to set the number

Work backwards from a customer, not forwards from a package. If an average job is worth $800 and you close one in three enquiries, a customer is worth about $2,400 in gross revenue before costs. If SEO brings two extra enquiries a month, that is roughly one extra job, or about $800. A $1,000 retainer only makes sense once the work reliably produces more than it costs — and that can take three to six months to show.

When to spend less

• You are a single-location business with a clear service area. Local fundamentals often do the heavy lifting, and you may not need a full retainer.
• Your website is new or technically poor. Fix the site before buying traffic work that lands on broken pages.
• You have not tracked enquiries. Without a baseline, nobody can tell whether the spend worked.
• Cash flow is tight. A paused month is better than a cancelled relationship built on panic.

When to pause or walk away

• Nobody can tell you what was done last month, in plain language.
• The report shows rankings but cannot connect them to calls or forms.
• You are being promised a specific position or a guaranteed timeline.
• Links are being bought in bulk from sites you would not recognise.
• The plan is $99 or $199 a month. At that price there are no skilled hours to spend, so the work is thin, automated, or both.

How our Grow plan fits

Pithy sells an SEO-adjacent plan, so it is fair to name it. Grow is $497/mo + GST and covers the local visibility work this guide describes: your Google Business Profile managed weekly, review requests and replies, local rank tracking, one new local service page each quarter, and a monthly scorecard. It replaces Protect ($150/mo + GST), so you never pay for both, and it is optional and month-to-month after your included care. You can see exactly what is included here.

We do not promise rankings, and we will not sell Grow on a first call to someone whose website cannot yet convert an enquiry. If a smaller budget is the honest answer, we would rather say so. A guide that told every reader to buy the biggest plan would not be worth reading.

Commercial disclosure: Pithy sells websites and the Grow plan ($497/mo + GST) described above, so we benefit if a reader hires us. This guide is written to be useful even if you run the work yourself or hire somebody else.
