We do not have a limit to the number of visitors. However, there is a physical limit our network can handle.
There is no way to determine the maximum number of visitors your site can sustain. Each site is different and the amount of traffic you can handle will depend on the resources each visitor is using. A very efficiently coded website that uses few resources per visitor would allow a large number of visitors to visit your site at the same time, while a poorly or inefficiently coded website may become a resource hog with only a few visitors on simultaneously. How many visitors your site can handle is largely determined by how your site is coded.
If you are using a content management system (CMS), you may want to utilize some of the tips in the following articles to increase the number of visitors your site can handle.
You can view your site statistics, like the number of visitors and which browser they use. Your cPanel includes a statistics program called AWStats.
What about huge and unexpected spikes in traffic?
Basically, if you spike the server too hard or for too long, you can be suspended for taking the resources from your fellow shared server users. If you don't want this to happen, you need to move to a dedicated server.
If I need to handle more traffic, what should I do?
Shared, reseller, and VPS all handle the same amount of traffic. My best recommendation is to upgrade to a dedicated server, or a more powerful dedicated server.



whether the HostGator will not happen like that if I use shared hosting, sorry for my bad english
