Hello, HTML validator brings "Attribute name not allowed on element meta at this point" for all my meta tags. Yet, as I understand, it is essential to keep meta-description for SEO, for example. I read a couple of articles on how to fix that and one of them suggests considering  HTML5 custom data attribute instead of name: Do you think I should try   to validate my page? And     instead of ? I will appreciate your advise very much!

Hello, Could you please let me know why might my website's DA have fallen down in merely a week? What might be a reason? I also noticed traffic from google dropped down at the very same week. Will be very thankful for any advise!
