Apply Site Policy to Multiple Sites with PnP PowerShell

[Russ Thomson]

I have 1000's of sites which I wish to apply a site policy to. This page describes how to create a policy in the content type hub, and then activate the Site Policy feature and apply the created policy to a site using PnP PowerShell - the 2nd script on the page.

I am a PowerShell/ PnP PowerShell novice, but was able to activate the Site Policy feature for a test site and apply a policy using the script (although when I run that 2nd script I get a "A parameter cannot be found that matches parameter name 'Web'." error for line 8, but it still works). 

What I'd like to do next is add a policy to multiple sites - e.g. from a list of site url's - in one go: is this possible?

Yeah that's pretty straight forward, question is where is the list?  Is it a SharePoint list or a Excel/CSV file ?  as you need to import it

Here is a base code you can use:

$AdminSiteURL = "https://contoso-admin.sharepoint.com"
 
Try {
    #Connect to Admin Center
    Connect-PnPOnline -Url $AdminSiteURL -Interactive
  
    #Get All Site collections (You will change this later on)
    $SitesCollection = Get-PnPTenantSite
  
    #Loop through each site collection
    ForEach($Site in $SitesCollection)  
    {  
        Enable-PnPFeature -Identity "ID OF YOUR FEATURE"
        Write-host -F Green $Site.Url  
    }
}
Catch {
    write-host -f Red "Error:" $_.Exception.Message
}

@NicolasKheirallah - perfect: works like a charm. Thank you! Bonus question: do you know how to automatically apply a policy to new sites when they're created - is this maybe something which can be set up in the Central Admin site (which unfortunately I don't have access to)?

No but you can create a site template and apply it each time you create a site
