What users say
Pros
- Help requests get patient, clear answers with follow-up until the issue is fully resolved.
- First-time site building works without design knowledge, guided step by step until the finished site is live.
- Gets a full website online on a small budget with easy-to-navigate tools.
- Sites built through the service reached the top of search results within a year of launch.
Cons
- Cancelling is not possible from the account page, so a discounted signup can be charged the full subscription.
- The monthly price and ongoing costs are not made clear at signup, which leads to billing disputes later.
- The free domain offer covers limited extensions, and wanted domains cost extra plus a renewal hold on the card.
- Results vary between assignments, with some needing all of the direction supplied rather than proactive input.
