Build an indicative estimate from your own inputs.
The calculator creates a planning scenario and a copyable summary. It is not a fixed quote or guarantee.

Organic sessions become valuable only when the visitor matches the service, completes a useful action and can become a customer. Ranking reports should be connected to enquiries, qualified leads and sales.
Use a visitor-to-lead conversion rate
Measure contact forms, calls, WhatsApp enquiries, quotation requests or booked consultations. Use a conservative rate if analytics is new, and separate branded searches from non-branded discovery.
Separate enquiries from qualified leads
Not every enquiry fits the budget, location, timeline or service. Qualification rate prevents the model from treating spam, job requests and unrelated messages as sales opportunities.
Apply the real close rate
The sales process determines how many qualified leads become customers. Response speed, proposal quality, trust evidence, pricing and follow-up can improve or reduce the return from the same traffic.
Use gross profit, not only revenue
Revenue can look impressive while delivery costs remain high. For ROI planning, multiply estimated revenue by a realistic gross margin before comparing the result with SEO investment.
Track by landing page and query group
Separate local service pages, solution pages, tools, articles and branded traffic. This shows which content assists enquiries and which pages attract visitors who never reach a commercial action.
Review the model every month
Update assumptions using Search Console, analytics, CRM and closed-order data. The calculator is useful when it becomes more accurate over time—not when the first estimate is treated as a guarantee.
Common questions

It should identify deliverables, exclusions, milestones, payment terms, technology, deployment, credentials, testing, support and change-request handling.
