Alert if a certain tag is missing in the page source

User question:

> How to check a web page for the absence of a particular meta tag?

> If it's missing, alert me.

> Concretely, if this tag is missing, I would like to know about it:

> <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">

 

This is possible via a plugin.

 

The following plugin only checks the availability of that tag and does not monitor changes in the page content. So you will only get a notification if this tag is missing.

 

Sub Wsw_BeforeCheck()
   'Disable optimizations and always check this bookmark by content
   Bookmark_SetProperty("checkmethod", "content")
End Sub
 
Sub Wsw_CompareVersions(ByRef $sMemWeb, ByRef $sMemLocal, ByRef $sStatusMessage, ByRef $iStatusCode)
   'default value of iStatusCode is 0 (=no update)
   
   Dim $bFound = InStr(UCase($sMemWeb), "<META NAME=""ROBOTS"" CONTENT=""NOINDEX, NOFOLLOW"">") > 0
   
   If $bFound = False Then
      'Tag not found -> alert update
      $iStatusCode = 1
      $sStatusMessage = "TAG not found"
   End If
End Sub
