The service uptime for any hosting account is of considerable importance. If you are using a web server which has regular issues and your site is not available for extended periods of time, it is more likely that website visitors won't return. Provided you have an online store, for instance, this would mean lost clients and much less profit. Your websites could even get penalized by search engines with lower rankings regardless how good their content is. To avoid this type of scenario, always make sure that the hosting service you get is stable. That way, the success of your site will depend only on its content and your advertising campaigns and will not be affected by hosting-related variables that you have got no control of.
