Why this matters
The EU is attractive because the same directive creates shared demand, but each member state creates local implementation questions. That is exactly the pattern that supports programmatic SEO without becoming thin content.
The content moat is not one article about the directive. It is a country matrix covering thresholds, salary range disclosure, reporting timing, worker categories, and enforcement uncertainty.

Create a hub for EU pay transparency, then add country briefs for Germany, France, Netherlands, Spain, Italy, Poland, Ireland, Belgium, Sweden, and Denmark first.
The first tool should remain the EU pay gap calculator. The second should be a readiness checklist that asks for headcount, country footprint, worker categories, salary bands, and current reporting maturity.
