How to check if SharePoint site exists using PowerShell?

Question

I am using SharePoint 2016, and I have a small PowerShell Script that requires me to provide the SharePoint Site URL manually, so I need to check if the provided SharePoint Site URL already exists or not using PowerShell without raising errors.

I tried the below cmdlet to check if the SharePoint site exists

Get-SPWeb -Identity $url | Select-Object -Property Exists

but I got this error if the provided SharePoint URL is not valid or the SharePoint site is not exists

Get-SPWeb : Cannot find an SPSite object that contains the following Id or Url: http://test.
At line:1 char:1
+ Get-SPWeb -Identity $url | Select-Object -Property Exists
+ ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (Microsoft.Share....SPCmdletGetWeb:SPCmdletGetWeb) [Get-SPWeb], SPCmdletPip
   eBindException
    + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletGetWeb

How can I ensure that the provided SharePoint Site URL is a valid URL and the SharePoint site exists using PowerShell without showing this error if the SharePoint URL was not found or incorrect?

Check if site exists in SharePoint using PowerShell Script

To check if a SharePoint Site exists using PowerShell, you have to use Get-SPWeb with -ErrorAction SilentlyContinue as the following:

$siteURL = "http://SiteURL"
$spWeb  = Get-SPWeb -site $siteURL -ErrorAction SilentlyContinue
if($spWeb -ne $null)
{
  write-host "$siteURL is found"
}
else
{
  write-host "$siteURL is not found"
}

Output
