Are additional meta tags important for a blog?

Question

JavaScript

Are meta tags important, for example:

<meta property="og:type" content="blog">
  <meta property="og:site_name" content="">
  <meta property="og:title" content="">
  <meta property="og:description" content="">
  <meta property="og:url" content=content="">
  <meta property="og:locale" content="ru_RU">

And for twitter and similar systems:

<meta name="twitter:card" content="summary_large_image">
  <meta name="twitter:site" content=""">
  <meta name="twitter:creator" content="@">

  <meta name="twitter:title" content="">
  <meta name="twitter:description" content="">
  <meta name="twitter:image:src" content="">
  <meta name="twitter:url" content="">
  <meta name="twitter:domain" content="">

For when using the plugin (ala Pjax ) - instantClick makes it impossible to update all meta tags, it only updates the content body. The site is static.

Answer 1

Perhaps the TIC of the site is of great importance, everything else is of little importance. However, any constructor will not be effective if "unimportant" details are omitted. The combination of SEO will give a good result. Well, think for yourself, do you really not like it when you immediately throw the image of the product on social networks with a link?
