Add-ons are optional extras attached to the service you are ordering.
TYPICALLY OFFERED
Dedicated IP address Additional disk space Paid SSL certificates Additional backup retention Priority support options Domain privacy, on domain orders
WHAT TO ACTUALLY TAKE
Domain privacy is worth it for most people, as it reduces spam and keeps a home address out of a public database.
Most others are not needed at the start. You can add them later from Services > My Services > Addons, with the charge prorated to align with your renewal date.
WHAT IS OFTEN UNNECESSARY
A dedicated IP for SSL. Free AutoSSL works on shared IPs and has done for years. The old advice is obsolete. A paid SSL certificate, unless a partner or regulator specifically requires organisation validation. Extra disk space before you know what you actually use.
THE PRINCIPLE
Order what you need now. Adding later is easy and costs nothing extra beyond the add-on itself. Removing something you did not need may not be refundable.
If an add-on is offered and you do not know what it does, ask in a Sales ticket before paying for it.
