Google wants to provide its customers (searching users) with an optimal internet experience. Websites with a proven track record of quality and reliability will obtain a preferred position, especially for premium search terms and when Google has to (temporarily) select a website for a higher amount of traffic.

To ensure uptime and website quality it is required to monitor all aspects of a website that influence the availability, stability and performance so that you will be able to respond instantly when a problem occurs, preventing damage to your reputation in Google. The most important aspects to monitor besides basic uptime are the Google PageSpeed scores, Google Malware registration, SSL certificate expiration and mobile usability (user experience) on all mobile devices.
