Hello everyone
I have a problem here. My website has been hit by Panda several times in the past, the first time back in 2011 (first Panda ever) and then another couple of times since then, and, lastly, the last June 2016 (either Panda or Phantom, not clear yet). In other words, it looks like my website is very prone to "quality" updates by big G:
http://www.virtualsheetmusic.com/
Still trying to understand how to get rid of Panda related issues once for all after so many years of tweaking and cleaning my website of possible duplicate or thin content (301 redirects, noindexed pages, canonicals, etc), and I have tried everything, believe me. You name it. We recovered several times though, but once in a while, we are still hit by that damn animal. It really looks like we are in the so called "grey" area of Panda, where we are "randomly" hit by it once in a while.
Interestingly enough, some of our competitors live joyful lives, at the top of the rankings, without caring at all about Panda and such, and I can't really make a sense of it.
Take for example this competitors of ours:
http://8notes.com
They have a much smaller catalog than ours, worse quality of offered music, thousands of duplicate pages, ads everywhere, and yet... they are able to rank 1st on the 1st page of Google for most of our keywords. And for most, I mean, 99.99% of them.
Take for example "violin sheet music", "piano sheet music", "classical sheet music", "free sheet music", etc... they are always first.
As I said, they have a much smaller website than ours, with a much smaller offering than ours, their content quality is questionable (not cured by professional musicians, and highly sloppy done content as well as design), and yet they have over 480,000 pages indexed on Google, mostly duplicate pages. They don't care about canonicals to avoid duplicate content, 301s, noindex, robot tags, etc, nor to add text or user reviews to avoid "thin content" penalties... they really don't care about anything of that, and yet, they rank 1st.
So... to all the experts out there, my question is: Why's that? What's the sense or the logic beyond that? And please, don't tell me they have a stronger domain authority, linking root domains, etc. because according to the duplicate and thin issues I see on that site, nothing can justify their positions in my opinion and, mostly, I can't find a reason why we instead are so much penalized by Panda and such kind of "quality" updates when they are released, whereas websites like that one (8notes.com) rank 1st making fun of all the mighty Panda all year around.
Thoughts???!!!
