We've been suffering under a Panda penalty since Oct 2014. We've completely revamped the site but with this new "slow roll out" nonsense it's incredibly hard to know at what point you have to accept that you haven't done enough yet.
We have thousands of news stories going back to 2001, some of which are probably thin and some of which are probably close to other news stories on the internet being articles based on press releases.
I'm considering noindexing everything older than a year just in case, however, that seems a bit of overkill. The question is, if I mine the logfiles and only deindex stuff that Google sends no further traffic to after a year could this be seen as trying to game the algo or similar?
Also, if the articles are noindexed but still exist, is that enough to escape a Panda penalty or does the page need to be physically gone?
