Reading the defaults

Trades defaults assume modest traffic, decent job values, and a lot of enquiries landing in the evening when nobody can answer the phone. If your average job is bigger or smaller, drag the value slider; it moves everything.

How to read the estimate, and how to use it honestly.

Pick the industry closest to yours and the calculator fills in starting numbers for traffic, conversion rate, average sale value, monthly enquiries and staff hours. Those presets are assumptions, not data about your business, so replace them with your own figures wherever you know them. Then choose a scenario and a monthly investment, and the chart shows how the estimated return builds over twelve months.

The three scenarios bracket the outcome rather than predict it. Cautious is genuinely cautious and is the case to test a budget against. Realistic is a middle case. Ambitious shows what a strong year could look like, and it is the ceiling, not the plan. If a decision only makes sense under Ambitious, treat that as a warning sign rather than an answer.

The SEO estimate credits only growth above where you are today, because revenue you already earn is not something new work created. It counts profit, not turnover, using a typical margin for your industry, and it trims the result further to allow for growth that might have happened anyway. Each of those steps makes the number smaller on purpose. The full working is in the methodology section below.

The AI agent estimate has two parts. One is staff time saved: the hours your team spends handling enquiries, multiplied by an hourly cost and by the share of that work the agent takes on. The other is enquiries recovered outside business hours, when nobody would otherwise answer. The agent's figures ramp up over its first two months rather than starting at full strength, the way a new system usually beds in.

Change one number at a time and watch what moves. The SEO return rises and falls in step with traffic, conversion rate and average sale value, so if you are unsure of any of them, try a low and a high figure and see whether the answer would change your decision. If it would not, the uncertainty does not matter much.

On the agent side, the staff-time part rests on hours you can count, so it is the easier half to check. The after-hours part depends on an assumption that half of all enquiries arrive outside business hours, so look at when your own enquiries actually come in before leaning on it.

The results show the twelve-month return after the investment you entered, the total return as a multiple of the investment, and the month in which the running total first covers the running cost. If it never does within the year, the calculator says so rather than stretching the timeline to make the picture look better.

The investment slider is there so you can test different budgets; it is not our price list, because plans are scoped to each business. And every figure here is an estimate built on stated assumptions, not a measured result from a client. What actually happens depends on your market, your competitors and how well the work is done.

A calculator cannot see your starting point either. Two businesses with the same traffic can be in very different positions with search engines and AI answers, and that changes how quickly anything moves. Use the estimate to decide whether the conversation is worth having, not to forecast a result.

Everything runs in your browser. Nothing you enter is sent to us, and there is no email to give.

If the estimate looks worth exploring, the free audit shows where your site stands with search engines and AI answers today, which tells you how much ground there is to make up before any of these numbers could apply.

03

Every number, shown its working.

We will not hide the assumptions behind a pretty chart. Here is exactly how the model arrives at each figure.

/ 01

SEO Agent maths

Baseline monthly revenue equals traffic times conversion rate times average value. Each scenario ramps traffic along an S-shaped curve over 12 months towards 1.35x (Cautious), 1.8x (Realistic) or 2.6x (Ambitious), with a conversion lift of 8%, 20% or 30%. The curve reaches nearly all of its uplift by month 12, and most growth lands in months 6 to 12, the way SEO actually compounds. Only revenue above your current baseline is credited.

/ 02

From revenue to credited return

We do not credit gross revenue. Each industry has a gross margin applied (Trades 35%, Hospitality 25%, Professional 55%, Health 45%) so the return is profit, not turnover. Then a 70% attribution factor is applied to acknowledge that some growth would have happened anyway. Conservative on purpose.

/ 03

AI Agent maths

Staff savings equal hours per week times 4.33 weeks per month times hourly cost (default $55 an hour) times the scenario deflection rate (22%, 35%, or 50%). Recovered revenue assumes half of all enquiries arrive after hours, captures a share of those (20%, 35%, or 50%), converts them at a 12% baseline times the scenario lift (1.05x, 1.15x or 1.3x), multiplies by average value, then applies the same industry gross margin and 70% attribution. The agent ramps up over its first two months: 40% of the monthly figure in month 1, 70% in month 2, then the full figure.

Anchors and honesty

Every default is a stated assumption, not a measured client outcome, and the sliders exist so you can replace our numbers with yours. The Cautious scenario is genuinely cautious. The Ambitious scenario is the ceiling, not the plan. Whatever the model says, your real number depends on market, competition, and execution, which is why we label everything on this page an estimate.
