Many hosting companies apply lots of limits of their hosting, whether that is per site or per server. We know that this can be confusing so we have tried to simplify this.
The only limitation on our hosting is the size of the hosting that you go for, as long as you don't use more disk space or memory than you have then you'll not hit a limit. Whether you have one larger site or half a dozen smaller ones, we'll not impose unnecessary limits.
We have some recommendations on how to use each of our packages, these are shown on our pricing page. But they are not hard limits, just advice. Same goes for bandwidth, no hard limits, just stay within acceptable use.
