How much does SEO cost — and what actually drives the number?

SEO cost is driven by four variables: the technical debt in the existing site, the number of markets and cities targeted, content volume required to reach topical authority, and the competitive intensity of the target keywords. A credible proposal shows its assumptions on all four.

Why this comes up so often

In Australia, this question tends to surface at the point where a business has outgrown its first marketing setup but has not yet built the measurement discipline to know what to change. The instinct is to add another channel. The more useful move is usually to establish a defensible baseline first.

What good looks like

• Every claim states its timeframe, baseline and attribution method
• Decisions are documented, including the ones that turned out wrong
• Leading indicators are reported between the lagging ones
• Underperformance is raised the month it happens, not at quarter end

Where to start

Document what you currently believe to be true, then check it. In our experience roughly a third of what a business assumes about its own funnel does not survive that exercise — and finding out early is considerably cheaper than finding out after a year of optimising the wrong constraint.
