SEO Structure for a Longevity Calculator Website

How to organize calculator, blog, schema, internal links, and crawlable pages for the life expectancy keyword cluster.

The core page should target the primary intent: life expectancy calculator, longevity calculator, remaining life calculator, and life expectancy by age. It must load fast, render the actual calculator immediately, and expose structured data for the software application and FAQ.

The blog should build supporting clusters around individual risk factors: smoking and life expectancy, activity and longevity, sleep and lifespan, BMI and mortality risk, country differences, and healthspan improvement plans.

Every article should link back to the calculator and to related articles. The calculator should link to the blog without distracting from the questionnaire flow.
