Finally got around to mounting an adwords campaign for PSQ. If you have a downloadable product and don't have an adwords campaign, I would encourage you to try it out. Its easy to set up, doesn't cost much and you can pack it in any time.
I've had a few hits from the ad over two days, nothing spectacular, but more than I was getting before.
I've also set up a notification so that I get an email to my gmail account if anyone comes to the site. For anyone who'd like to try it using ASP.NET just put some code like this in the Page_Load event:
// only fire if HTTP_REFERER is not null
// since null indicates a googlebot
string referer = Request.ServerVariables["HTTP_REFERER"] ;
if ( referer != "" )
System.Web.Mail.MailMessage em = new MailMessage() ;
em.Subject = "home page hit! holy cow!" ;
em.From = "Hits<email@example.com>" ;
em.To = "mygmail accoun at gmail dot com" ;
em.Body = "Remote = " + Request.ServerVariables["REMOTE_HOST"] + "\n" ;
em.Body += "Referer = " + Request.ServerVariables["HTTP_REFERER"] ;
SmtpMail.SmtpServer = "mail dot mydomain dot com" ;
