Read the guideCan a calculator page alone get AdSense approval?
Sometimes, but many tool-only sites struggle because the property does not yet look deep, editorial, or established enough. Content quality and overall site maturity matter.
Why include policy pages if the site is simple?
Because trust is part of usability. Visitors and reviewers need to see who runs the site, how the content is maintained, and what rules apply.
What still needs to be done after deployment?
Indexing, Search Console submission, and ad-consent configuration for EEA, UK, and Swiss visitors still need to be completed on the live stack.
