Why this helps SEO
A calculator alone is not enough
Search engines need more than a number box. They need clear
headings, supporting articles, internal links, and pages that
answer the next question after the calculation. That is why the
blog exists as a real part of the site, not as filler.
Next step
Use the calculator with the articles together
The strongest user journey is simple: read one guide, check your
own numbers in the calculator, then compare scenarios. That is
the behaviour we want to encourage because it is useful to real
visitors and looks far stronger to Google than a thin tool page.
