Perfect Ahrefs health score - technically sound and trustworthy by Google's standards

Instructional designers, project managers and L&D stakeholders routinely face the same planning problem: estimating how long an eLearning project will actually take. Guesswork leads to under-quoted budgets, missed deadlines and frustrated clients. Existing rules of thumb are either too academic or too vague, and they rarely account for content readiness, review cycles, multimedia demands or SME availability.
The eLearning Calculator is a free, professional web tool that turns five practical questions into a clear development-time estimate. It draws on two validated benchmark sets (Chapman academic research and Tucker real-world practitioner data) and adjusts for the factors that actually drive effort. The result is a realistic range teams can use for scoping, quoting and stakeholder conversations from day one.
Live since June 2025. Built by RETSA Group.
The tool has achieved a perfect Ahrefs health score of 100/100 (October 2025), placing it in the top 1 % of technically sound websites. It is already used by instructional designers and project managers to replace guesswork with data-driven estimates and to set clearer expectations with stakeholders.
Focused tool, not an over-engineered platform. Built around the exact questions L&D practitioners ask when scoping work. Dual industry benchmarks keep the estimates grounded in both research and real delivery experience. Mobile-friendly, shareable and deliberately simple so it gets used.
