最好的方法是找到名称为 关键字 的元元素并引用其 content 属性。你可以这样做：

Option Explicit

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
        End If
    Next

    MsgBox kwd

End Sub
