As a website owner, it's quite likely that you've faced issues with your website being down and non-functional without being aware, due to a server or network error. According to Murphy’s law this always happens when:

  • you just launched a great new product or functionality
  • you are on holiday
  • you want to showcase the website to a client

Life is that hard! How can you make it a bit easier? It is impractical to manually check the number of times your website faces unpredictable downtimes. Hence, to your rescue, you have a number of services online that offer free uptime monitoring.

We have put together a list of such free uptime monitoring services, but before we begin, if you're a WooRank customer then you already have access to uptime notifications for each website that you're tracking with an advanced review. To activate this service, just navigate to the project settings and tick the 'Uptime notifications' checkbox under 'Email subscriptions', then click save.
