Many website owners are still unfamiliar with the .xyz domain name extension. Because of that, they don’t yet trust it and ask if it’s safe. They seem to be concerned that their site might be hacked more easily than if they use a .com extension.
That isn’t an extra risk. This lack of trust is not unusual with new products. It often takes a few trailblazers to show everyone that a new product is good and worthwhile.
SimpleSite would not offer this premium option to you without being certain it is secure.
In fact, many large companies have migrated to .xyz because they’re able to get one-word domains. Alphabet Inc., the parent company of Google, has chosen abc.xyz as its URL. \
If Google likes it, it’s got to be good for search engine results.
