You should try the code below:

 if (objWeb.IsRootWeb)
 {   
    SPContentType contentType = objWeb.ContentTypes["Wiki Page"];
    if (!contentType.Fields.ContainsField("Keywords"))
    {
      SPField field = objWeb.Fields["Keywords"];
      SPFieldLink fieldLink = new SPFieldLink(field);
      contentType.FieldLinks.Add(fieldLink);
      contentType.Update(true);
    }
 }
 else
 {
   SPContentType contentTyperoot = site.RootWeb.ContentTypes["Wiki Page"];
   if (!contentTyperoot.Fields.ContainsField("Keywords"))
   {
     SPContentType contentType = site.RootWeb.ContentTypes["Wiki Page"];
     if (!contentType.Fields.ContainsField("Keywords"))
     {
       SPField field = site.RootWeb.Fields["Keywords"];
       SPFieldLink fieldLink = new SPFieldLink(field);
       contentType.FieldLinks.Add(fieldLink);
       contentType.Update(true);
     }
   }
 }

I hope someone is being helped from my code :)
