The SmartViper Health Check Widget

The SmartViper health check gives you a combined score of a wide range of key parameters. Whilst other lesser web site health checkers use a very basic algorithm to calculate the health score of a site, we use a very wide range of parameters which have been carefully selected and adjusted over time so as to truly reflect the health of your site. As a result, the SmartViper Health Check widget gives you the most accurate and true health score that you will find anywhere on the web. read more...
