Workflow

Turn one article update into a tracked publisher placement

Start with one claim, one FlipCalc source URL, and one reader action. The goal is to make the pitch easy for an editor to verify and easy for readers to use.

Step 1

Choose one source asset

Pick the Fee Index, exact-answer dataset, Fee Changes timeline, organic guide dataset, Q1 report, methodology page, or platform calculator that best supports the article claim.

Step 2

Add the calculator widget

Use the embed page to place a no-signup calculator near the fee explanation so readers can test sale price, shipping, fees, and item cost.

Step 3

Track outreach and follow-ups

Move the publisher into the tracker CSV with the chosen angle, source asset, status, follow-up date, result, and notes.

Recommended placements

Match each publisher page to one asset and one widget position

Use the placement type to choose the right source URL, decide where the calculator should appear, and keep outreach tracking consistent after the first contact.

Outreach tracker

Track targets, status, and follow-ups

Use the CSV template to keep every publisher target tied to one angle, one source URL, and one follow-up date. That makes the Fee Index plus embed-widget outreach loop measurable instead of relying on memory.

The template includes columns for priority, angle, asset URL, contact details, status, first contact date, follow-up due date, result, and notes.

Tier-one targets

Start with reseller media and newsletters

These examples come from the authority-building target list. Use them as starting points for outreach angles, then copy the best-fit target into the tracker CSV with the asset URL you plan to pitch.

Use when a publisher already explains marketplace fees but does not give readers a calculator or source dataset.

Resource page addition

Use when a reseller blog has a tools page, pricing guide, sourcing checklist, or beginner resource hub.

Marketplace news follow-up

Use when a publication covers a fee change and needs a dated source plus a calculator readers can test.

Copy-paste pitch

FAQ

Publisher kit questions

When should I use the publisher kit?

Use the publisher kit when an article, newsletter, or resource page needs source URLs, an embeddable fee calculator, and short outreach copy in one place.

When should I use publisher-kit.json?

Use publisher-kit.json when a crawler, dashboard, or internal workflow needs the citable assets, feeds, reports, embed page, target list, and tracker file in a machine-readable manifest.

When should I use the embed page?

Use the embed page when a publisher wants readers to test sale price, shipping, fees, and item cost directly inside a reseller guide or resource page.

How should outreach be tracked?

Use the outreach tracker CSV after selecting targets so each publisher has an owner, angle, source asset, status, follow-up date, result, and notes.

Embed guidance

Use data for the citation and the widget for the reader

The strongest publisher placement pairs a claim with a source URL and then gives the reader a calculator. Link the Fee Index for comparable fee rows, Fee Changes for dated policy movement, and Reports for narrative summaries.

Place the embedded calculator near the fee explanation or pricing section so readers can test the exact marketplace, sale price, shipping setup, and item cost discussed in the article.
