How to find broken links in Sitecore.

Well, recently i take it clone of website and found too much broken links so i want to listed all broken links and fix it one by one.

I search about that and read so many articles so i found a easiest way to identify broken link.

a. First one we can go directly on control panel under reports > Scan the data for broken links.

just click on that and it will open a new popup window.





choose data base and press scan button it will take few seconds or minutes as per database and will show you a list of broken links. for fix it just click on item and fix it.


b. Second way i found by power shell. just go on launchpad and click on PowerShell ISE.

it will open a new popup looks like below images. just copy below script and paste there and press execute button. it will take few seconds to generate broken list.

#Script Copied..

$database = "master"
$root = Get-Item -Path (@{$true="$($database):\content"; $false="$($database):\content"}[(Test-Path -Path "$($database):\content\home")])

$versionOptions = [ordered]@{
    "Latest"="1"
}

$props = @{
    Parameters = @(
        @{Name="root"; Title="Choose the report root"; Tooltip="Only items in this branch will be returned."; Columns=9},
        @{Name="searchVersion"; Value="1"; Title="Version"; Options=$versionOptions; Tooltip="Choose a version."; Columns="3"; Placeholder="All"}
    )
    Title = "Broken Internal Links Report With Additional Info"
    Description = "Choose the criteria for the report."
    Width = 550
    Height = 300
    ShowHints = $true
}

$result = Read-Variable @props

if($result -eq "cancel"){
    exit
}
