Dim HeadTag As HtmlHead = CType(Page.Header, HtmlHead)
metaTag.Attributes.Add("name", "description")
metaTag.Attributes.Add("content", "your description goes here")
HeadTag.Controls.Add(metaTag)
metaTag = New HtmlMeta
metaTag.Attributes.Add("name", "keywords")
metaTag.Attributes.Add("content", "your keyword go here")
HeadTag.Controls.Add(metaTag)
