You are concerned if you offer European users one of the services covered by the EAA: e-commerce, banking and financial services, ticketing and transport, electronic communications, audiovisual media or digital books.
Micro-enterprises in the services sector (fewer than 10 employees and less than €2M in turnover) benefit from an exemption, but accessibility remains an asset: it improves the experience for all users and strengthens your quality signals with Google and AIs.
