Welcome to the Q&A Forum

Yes, There is no big advantage rather than H1 alone.  Just a clickable H1.

@ tadbir gostaran I raised the same question here. Waiting for the answer...

However the Just-Discovered Links beta is working fine. On the other hand,  The G+, FB Sharing counts been increased rather than authority metrics.

There is no optimal position for H1 Tags. But According to Bruce Clay's SEOToolset analysis, H1 should appear before H2 tag.

And I really got proven record when I was working with a websites using Bruce's SEOToolset.

Thanks for raising this question Chris!  I would also wanted to know this, as the competition of the apps in Play is much high.

I guess, number of referrals/traffic to a particular app page may also count. but not sure. Lets wait for any positive proven record/answer.

I have been waiting to see the updated authority metrics from Opensiteexplorer.org.

But still it is showing old data. and showing "next index update: August 26, 2013"  as the date is 27th August today.

Is there any delay in update?
