Why the UK is attractive
The UK has enough employer scale and a major employment rights reform cycle. That creates timely searches from employers trying to understand new obligations.
The best initial content should be explainers and checklists rather than pay calculators, because the demand is policy-change oriented.
Recommended cluster
Create pages for Employment Rights Act overview, day-one rights, zero-hours contracts, fire-and-rehire, sick pay, dismissal risk, and employer readiness.
Later, add calculators for holiday pay and redundancy pay if the site expands beyond overtime and payroll.
