Use of hgroup tag and how much well for SEO it is?

Question

I used hgroup tag like as in section. I want to know that it's well for SEO or not and this is a correct use of hgroup.

HTML:

<section>      
<hgroup>
          <h1>CCTV Camera's online view on your 3G phone</h1>
          <h6><i class="fa fa-map-marker"></i> Shadman, Lahore</h6>
          <h6><i class="fa fa-clock-o"></i> 29 Aug 12:22 2014</h6>
          <h6>Ad ID: <span>1249586</span></h6>
          <h6> Views: <span>2</span></h6>
        </hgroup>
</section>

CSS:

section h1{
    font-size:24px;
    text-transform:capitalize;
    line-height:25px;
    font-family:"Lucida Sans Unicode", "Lucida Grande", sans-serif;
    font-weight:normal;}
section h6{
    font-size:10px;
    font-family:"Lucida Sans Unicode", "Lucida Grande", sans-serif;
    font-weight:normal;
    text-transform:capitalize;
    float:left;
    padding:0 0 0 1%;
    color:#999;}
section h6 i{
    color:#85B7F3;}
section h6:nth-child(4),
section h6:nth-child(5){
    color:#000;
    float:right;
        padding:0 1% 0 0%;}
section h6 span{
    font-weight:bold;}

Answer 1

The <hgroup> is not an official HTML tag so its use is discouraged and its meaning may change.

Since it is not an official HTML tag it almost certainly has no SEO value. And, even if it did, it would be so small that it wouldn't be worth focusing on.

Answer 2

The hgroup element was removed from HTML5 more than a year ago.

For alternatives, there is now an own section in HTML5:
Subheadings, subtitles, alternative titles and taglines

In short, you should not use heading elements (h1-h6) for the "subtitles" anymore, as they’d create a wrong document outline.

You could use something like this:

<section> 
  <header>     
    <h1>CCTV Camera's online view on your 3G phone</h1>
    <!-- just using 'div' in this example; better use more specific markup, see below -->
    <div>Shadman, Lahore</div>
    <div>29 Aug 12:22 2014</div>
    <div>Ad ID: 1249586</div>
    <div>Views: 2</div>
  </header>
</section>

Side notes:

• Don’t use i for (font) icons. Use span instead.
• You could use the time element for the publication date.
• You could use the dl element for the metadata like "Views" and "Ad ID" (and even for the date and place if you want to provide names in dt for them).
