Reconciled the published tool count to a single audited figure (1,169 calculators, 251 guides, 51 datasets) used consistently across the site.
Added sitewide Organization and WebSite structured data and published editorial standards and a data-currency process.
Added around 150 new calculators across SaaS metrics, NZ money and tax, statistics, developer tools, physics and chemistry.
Launched the Ask Cal helper, which recommends the right calculator, guide or dataset from the site's own content.
Regenerated the complete sitemap and confirmed access for the major AI crawlers.

Ongoing

Source data is reviewed on a twice-monthly cycle, and tools are updated whenever a New Zealand rate, threshold or rule changes. Larger events such as the 1 April tax-year rollover and the May Budget trigger a fuller review. The full process is in how we keep data current.
