Kentico SEO - Move Viewstate down the page

To move the Viewstate down the page when using Kentico Portal Model you need to override Render method on the ~\CMSPages\PortalTemplate.aspx.cs file e.g.

    protected override void Render(System.Web.UI.HtmlTextWriter writer) {
        System.IO.StringWriter stringWriter = new System.IO.StringWriter();
        HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
        base.Render(htmlWriter);
        string html = stringWriter.ToString();
        int StartPoint = html.IndexOf("<input type=\"hidden\" name=\"__VIEWSTATE\"");
        if (StartPoint >= 0) {
            int EndPoint = html.IndexOf("/>", StartPoint) + 2;
            string viewstateInput = html.Substring(StartPoint, EndPoint - StartPoint);
            html = html.Remove(StartPoint, EndPoint - StartPoint);
            int FormEndStart = html.IndexOf("</form>");
            if (FormEndStart >= 0) {
                html = html.Insert(FormEndStart, viewstateInput + Environment.NewLine);
            }
        }
        writer.Write(html);
    }
