A site monitor checks pages regularly to make sure it is available for visitors. Basic monitors check if the page is working.
Important pages within the site should have enhanced monitors that test if a completed form behaves the way it should. Enhanced monitors are more expensive to setup and keep running so the page in question needs to justify the additional expense.
2. Backup System
Have you thought about what happens if the server goes down? Make sure the backup system is configured properly, and the recovery process has been tested so you know it works.
3. Traffic Loads
Think about what might happen to your site if it gets an influx of heavy traffic. There are load test software tools that allow you to simulate heavy loads. If you are expecting big crowds, this is a must.
4. Protected Pages
Does your site have pages that require user credentials to view? If so, do the credentials work? From the opposite angle, also check to see that the pages can’t be viewed without proper credentials. Make several attempts to get to those URLs without proper credentials to make sure the security is working as expected.
5. Secure Certificate
If your site is ecommerce, or you’re using encrypted pages to protect visitor privacy on a form or elsewhere, you’ll want to check your certificate on launch day.
To do this, go to the encrypted section of your site. When the lock appears in the address bar, right click on it and read the message your visitors will read. It should have your name on it and state that it’s valid. If the lock doesn’t appear or the name isn’t right, let your provider know.
