    Default How to Click a link on webpage

    I am unexperienced when it comes to navigating websites using VBA (or any code). I have been able create code to open the desired websites but now I am trying to automate "clicking a link" to save additional time.

    I have an excel file full of various patent numbers. I have been able to create code that will open each of the patents within google.patents.
    For example

    Now I would like to automate clicking on the "Download PDF" link.

    I am not sure where to start. Any help would appreciated.

    Try this. Instead of clicking the link, this gets the href from the link and downloads it to the desktop. Make sure to change the commented line to where you want the files saved. Also, the code can be amended to loop through several patent numbers. This one just does the one that you gave in the OP.

    Private Declare PtrSafe Function URLDownloadToFile Lib "urlmon" _
        Alias "URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, _
        ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
    Sub DownloadPDF()
    Dim IE As Object: Set IE = CreateObject("InternetExplorer.Application")
    Dim URL As String: URL = ""
    Dim SP() As String: SP = Split(URL, "/")
    Dim pNum As String: pNum = SP(UBound(SP))
    Dim Path As String: Path = "C:\Users\USERNAME\Desktop\" 'Change to where you want the file to be saved
    Dim Link As Object
    Dim HTML As Object
    IE.navigate (URL)
    Do While IE.busy = True Or IE.readystate <> 4
    Set HTML = IE.document
    Set Link = HTML.querySelector("#wrapper > div:nth-child(2) > > section > header > div > a")
    downloadFile Link.href, Path, pNum
    Set IE = Nothing
    End Sub
    Sub downloadFile(URL As String, Path As String, FileName)
    URLDownloadToFile 0, URL, Path & FileName & ".pdf", 0, 0
    End Sub
    To add code to a workbook. Hit Alt+F11. Hit Alt+I+M to insert new module. Then paste code.
    Array formulas must be entered by hitting Ctrl+Shift+Enter.

    We can't solve problems by using the same kind of thinking we used when we created them.

    Imagination is more important than knowledge.
