A guide, not a guarantee. This multiplies your budget by your click-through and conversion assumptions to estimate click potential. Actual results depend on your keywords, competition, Quality Score and landing page. The cost per click shown is a typical industry average and will vary with your keywords and competition. These figures are revenue, not profit, and do not include your own costs of delivering the work or any management fee.

The Google Ads maths

Four numbers decide your return

Google Ads is simple maths. Your budget and cost per click decide how many clicks you buy. Your conversion rate turns those clicks into enquiries. Your close rate and customer value turn those enquiries into revenue. Improve any one of them and your return goes up.

Budget

Your monthly ad spend. More budget means more clicks, until you saturate the searches your customers make.

Cost per click

What each click costs. Tighter keywords and a better Quality Score drive this down, which is where we earn our keep.

Conversion rate

The share of clicks that turn into an enquiry. A faster, sharper landing page lifts this and multiplies everything downstream.

Customer value

What a customer is worth. When repeat business is added in, most Adelaide businesses can afford to pay far more per lead than they think.

Spend is easy to control. The return comes from clicks, conversions and customer value. Get those right and the maths works on its own.

Estimates only, based on the figures you enter.
