Use the right route for the prospect
Article calculators
Use exact calculator links when a page already has a clear finance, health, education, or measurement intent.
Citations and data
Use structured references when an editor needs source notes, catalogue files, or methodology links.
Trust layer
Clear enough to cite, light enough to use
No hidden links
Widget packages use visible attribution and publisher-safe citation guidance.
Calculation context
Calculator pages explain inputs, assumptions, limitations, FAQs, and sources where relevant.
Exact-asset routing
Specific article pitches should send readers to the matching calculator or widget package first.
Measurement gate
Pilot with small batches first
Use 10 to 15 recipients to confirm links, UTM capture, event capture, and message fit before scaling. Treat 50 targeted sessions as a usability diagnostic, not proof of the segment.
10-15 recipients: links and events
50 sessions: usability signal
150-200 sessions: compare variants
FAQ

When should outreach link to this page first?
Use this page first for broad publisher, blogger, resource-page, and small-business outreach where the recipient needs the overall embed and citation context.
When should outreach link to a widget package first?
Use the exact widget package first when the prospect has a matching article or resource page, such as property-loan, fitness, or unit-conversion content.
Can a publisher request a calculator that is not listed?
Yes. The request CTA routes to the contact page with the widget request reason selected.
