Explore what additional organic search traffic could mean for your business. Adjust the sliders to model enquiries, sales, contribution margin and SEO investment, then see the return over time.
Use growth above your existing baseline. Counting current customers again would inflate the return.
Use revenue you earn and your delivery margin. An agency commission and a property price are different inputs.
Try lower and higher conversion, a longer ramp-up and realistic costs. Save each scenario as a CSV.
Your location, customer journey and revenue model change the calculation. Choose the local version for relevant keyword examples and currency, or begin with this GBP model. Example figures are editable assumptions, not measured search demand.
Model the journey from a relevant search visit to an enquiry, then from an enquiry to a paying customer. Use revenue from the work you win and a contribution margin that accounts for delivery costs.
Research examples · No measured search volume
Use the commission or fee your business earns, rather than the advertised value of a property. A longer sales cycle belongs in the ramp-up assumptions and a cautious lead-to-customer conversion rate.
Research examples · No measured search volume
Switch to online sales to model visit-to-order conversion directly. Enter net order revenue and allow for product costs, booking fulfilment, refunds and payment fees in the margin.
Research examples · No measured search volume
The Calculation
The model compares the contribution from additional organic customers with the SEO investment needed to pursue them. Existing revenue stays outside the calculation.
This is a scenario, not a forecast. It does not model seasonality, changing margins, repeat purchases, lifetime value, tax, fixed overhead, attribution overlap or cash collection delays. Include the cost of content and implementation in your inputs, and use consistent tax-exclusive values. Validate assumptions with website analytics and enquiry measurement.
This general calculator uses GBP. The Gibraltar version also uses GBP, Marbella and Sotogrande use EUR, and Dubai uses AED. Each version starts with a clearly labelled example scenario. Switching location does not perform a currency conversion.
No. It does not connect to your Google accounts, scrape search results or pull live keyword volumes. Use your own search, analytics and sales data to replace the illustrative inputs.
No. The result is the arithmetic of your assumptions. The calculator cannot know whether traffic, rankings, conversion or sales will reach your inputs. Compare cautious, working and higher-growth scenarios, then review them against actual performance.
Revenue does not account for the cost of delivering a product or service. Contribution margin deducts those variable delivery costs before SEO investment is subtracted. The resulting figure is incremental contribution after SEO, not your company’s accounting net profit.
No. Calculations and CSV downloads happen in your browser. The calculator does not send your inputs to OXO, connect to your Google accounts or save them between visits. Changing location opens a fresh example scenario.
Start with what you can afford to invest, the specific work required and conservative estimates from your own business. Test the required additional visits and sales against your capacity and margins. Review the proposed SEO scope with OXO before treating any example cost as a budget or quotation.
We can review your website, search opportunity and measurement, then scope the work around your business. Explore OXO’s SEO packages or talk through your starting point.
