Hi Im implementing Seo and following Paul Seal example https://codeshare.co.uk/blog/how-to-optimise-your-website-for-search-engines-seo-in-umbraco/

In the surfacecontroller I want to use the modelsbuilder instead of Currentpage

 namespace FionaWhitfieldArt.Controllers
{
    public class SiteLayoutController : SurfaceController
    {
        private string PartialViewPath(string name)
        {
            return $"~/Views/Partials/SiteLayout/{name}.cshtml";
        }

        public ActionResult RenderMetaData()
        {
            MetaDataModel model = new MetaDataModel();
            IPublishedContent homePage = CurrentPage.AncestorOrSelf("home");
            string domainAddress = homePage.UrlWithDomain();
            string title = CurrentPage.GetPropertyValue<string>("title");
            model.Title = !string.IsNullOrEmpty(title) ? title : CurrentPage.Name;
            model.Description = CurrentPage.HasProperty("description") ? CurrentPage.GetPropertyValue<string>("description") : null;
            model.Keywords = CurrentPage.HasProperty("keywords") ? CurrentPage.GetPropertyValue<string>("keywords") : null;
            if(CurrentPage.HasProperty("socialShareImage"))
            {
                int mediaId = CurrentPage.GetPropertyValue<int>("socialShareImage");
                var mediaItem = Umbraco.Media(mediaId);
                model.ImageUrl = $"{domainAddress.TrimEnd('/')}{mediaItem.Url}";
            }         
            model.Url = CurrentPage.UrlWithDomain();
            return PartialView(PartialViewPath("_MetaData"), model);
        }

    }
}

Many Thanks/Christina
