Here are my nifty PowerShell scripts to check if a given URL of the Site Collection, Site, List, Document (File), and column objects exist in SharePoint. You can utilize these helper functions wherever required.

PowerShell to check if Site Collection Exists:

Here is my custom function and function usage with PowerShell to check if site collection exists. SharePoint PowerShell to check if site collection exists:

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

#Custom Function to Check if Site Collection Exists in Given URL
Function Check-SiteExists($SiteURL)
{
    return (Get-SPSite $SiteURL -ErrorAction SilentlyContinue) -ne $null     
}

#Variable for Site collection
$SiteURL= "https://demo.crescent.com/sites/operations" 

#Call the function to check site exists
if(Check-SiteExists($SiteURL))
{
    write-host "Yes, Given Site Collection Exists!" -f Green
    #Proceed with your script
}
else
{
    write-host "No, Site Collection doesn't Exists on given URL!" -f Red
}

Alternatively, you can try:

$SiteURL = "https://portal.crescent.com/"
 
Try{ 
    $Site=Get-SPSite $SiteURL -ErrorAction SilentlyContinue
}
catch{ 
    write-host Site Collection with URL:$SiteURL Does not Exists!
    return
}
