Published: Alex Shashenko 2023-01-26 all articles | Glossary | FAQ

Every person who owns the website wants it to be working well and without any possible issues as much time as possible. In other words, website uptime is one of the most important things for a website from its owner’s perspective. And the same goes for users - they want their favorite website to be accessible every time they want to visit. Moreover, various advertising, promoting and searching services rank websites higher if their uptime ratio is better.

Therefore, it is vital for the webmaster to keep website and server uptime at the highest border. But despite everything mentioned, not every novice webmaster knows the definition of uptime and its measurement. And this is by all means one of the first things every webmaster must know. Simply put, website uptime is the percentage ratio between uptime (online time) and downtime (unavailability time). And it must be as close as possible to 99.99%.

To achieve the letter, the webmaster must understand what is uptime monitoring. In general terms it’s a set of measures and routine performance checks to determine whether a website and its server are running without issues or down and not responding. And without those measures every website owner will suffer a lot of losses. From losing ranks in various aforementioned services to losing future customers, and then money. Simply put, if a website goes down its uptime will lower, its users will leave and related services will one-sidedly suspend the website's subscription and lower its rank in SERP and ads queues.

Downtime, uptime availability of a website

In technical terms, website uptime is a percentage ratio between website or server overall availability period and its downtime or unavailability period. It counts literally every second of a server uptime from first website launch and up to the very exact moment. And it could be as high as 99.99% with a 0.001% margin left for inevitable maintenance downtime as well as server-related first website’s launch issues. So, it must be as close as possible to this mark.

It is worth mentioning that various services count uptime differently for their purposes. Therefore, Google Ads, for example, doesn’t include maintenance downtime of websites and force majeure situations in its ranking measurements if you have a solid proof that it was not a malfunction of software, hardware or website code, for example. But other Ads services or search engines could still count it as a downtime even if you have a server data with timestamps.

As it was stated above about what does uptime mean, it is vital to perceive the highest possible uptime ratio of a website in order to promote it and gain an audience.

Website uptime, as it should be obvious, is one of the most important metrics for almost every aspect of the website.

But uptime itself is not only the metric for stability. Also, an indicator of reliability for various advertising and promotional as well as for search engines starting from Google.

Therefore, if you neglect website monitoring and keep your website working without any solid automated solution, you literally put your own money in danger. Because without monitoring you won’t be able to react quickly in case of emergencies. Which means downtime will be longer and probability of suffering from major financial and reputational losses along with users’ dissatisfaction and outflow. And it will lead to even more losses, because you will lose potential customers and possible revenue from those.
