How to enable default seo tags only to home page?

Everything works fine. Perhaps you did something wrong or opened some other page. These extensions methods are also used on the product/category/manufacturer details pages and work just fine.

hi i achieved this by making some changes in the following files

0) Presentation/Nop.Web/Views/Home/index.cshtml
1) Presentation/Nop.Web/Views/Shared/_Rool.Head.cshtml
2) Presentation/Nop.Web.Framework/UI/LayoutExtension.cs
3) Presentation/Nop.Web.Framework/UI/IPageTitleBuilder.cs
4) Presentation/Nop.Web.Framework/UI/PageTitleBuilder.cs

changes in 0) Presentation/Nop.Web/Views/Home/index.cshtml

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_ColumnsThree.cshtml";
}

changes in 1) Presentation/Nop.Web/Views/Shared/_Rool.Head.cshtml

modify after the head tag.

 

 @{
        var flag = false;
        if (ViewData.ContainsKey("title"))
        {
            if (ViewData["title"] == "Index")  // write your logic here for some other pages.
            {
                flag = true;
            }
        }
    }
    <title>@Html.NopTitle(flag)</title>
    <meta http-equiv="Content-type" content="text/html;charset=UTF-8" />
    <meta name="description" content="@(Html.NopMetaDescription(flag))" />
    <meta name="keywords" content="@(Html.NopMetaKeywords(flag))" />

changes in 2) Presentation/Nop.Web.Framework/UI/LayoutExtension.cs

added new parameter bool addDefaultDescription,

  public static MvcHtmlString NopMetaDescription(this HtmlHelper html, bool addDefaultDescription, params string[] parts)
        {
            var pageTitleBuilder = EngineContext.Current.Resolve<IPageTitleBuilder>();
            html.AppendMetaDescriptionParts(parts);
            return MvcHtmlString.Create(html.Encode(pageTitleBuilder.GenerateMetaDescription(addDefaultDescription)));
        }

do the same for NopMetaKeywords method too.

changes in 3) Presentation/Nop.Web.Framework/UI/IPageTitleBuilder.cs

  string GenerateMetaDescription(bool addDefaultDescription);
  string GenerateMetaKeywords(bool addDefaultKeywords);

changes in 4) Presentation/Nop.Web.Framework/UI/PageTitleBuilder.cs

 public string GenerateMetaDescription(bool addDefaultDescription)
        {
            var metaDescription = string.Join(", ", _metaDescriptionParts.AsEnumerable().Reverse().ToArray());
            var result = string.Empty;
            if (addDefaultDescription)
                result = !String.IsNullOrEmpty(metaDescription) ? metaDescription : _seoSettings.DefaultMetaDescription;
            else
                result = !String.IsNullOrEmpty(metaDescription) ? metaDescription : string.Empty;
            return result;
        }

do the same for GenerateMetaKeywords method too.
