Option Explicit
Sub GetData()
Dim ie As New InternetExplorer
Dim str As String

Sub GetData()
Dim ie As New InternetExplorer
Dim str As String
Dim wk As Worksheet
Dim webpage As New HTMLDocument
Dim item As HTMLHtmlElement
Set wk = Sheet1
str = wk.Range("Link").value
ie.Visible = True
ie.Navigate str
Do
DoEvents
Loop Until ie.ReadyState = READYSTATE_COMPLETE
'Find the proper meta element --------------
Const META_TAG As String = "META"
Const META_NAME As String = "keywords"
Dim Doc As HTMLDocument
Dim metaElements As Object
Dim element As Object
Dim kwd As String
Set Doc = ie.Document
Set metaElements = Doc.all.tags(META_TAG)
For Each element In metaElements
If element.Name = META_NAME Then
kwd = element.Content
