Hi,
The description should be very clear about the free and paid features. The difference is described in the sections “Additional Technical Features of the Professional Version”, “Is the service free of charge?” and “Limitations”. Please let me know if you have read this and something was not clear or some information was hidden. Then I will add this additional information to the description.
For an average website, the plugin is normally free as the basic features cover the needs of most websites. You just have to pay if you need more.
Best regards,
Marco
