Globehost not put any limits of no. of visitors but that depends on available RAM and CPU on your server.
In Shared hosting, one cpanel Account will get maximum 1 GB RAM and 25% CPU Max Limit.
If at any time of the day your server limits reached your site will start displaying error.
So you need to choose hosting plan according to your RAM and CPU Requirements and the number of visitors you are getting on your site.
In shared hosting, you can expect up to 800-1000 visitors in a day. If your site getting traffic at a single time then it may be less.
