None. We're seeing the opposite... slight drops in G-referrals, during what would normally be our busiest time of the year.
I have basically given up.
We're buying into the same theory. After 7 months of trying to fix an issue we have yet to discover and losing some of our rankings in other search engines as part of the recovery effort for Google, we decided to give up and move on.
It is, what it is... and the only thing we got from the site over the last 7 months were headaches and daily distractions. Kinda like a bad romance, we cut the ties and stopped working on it.
On the bright side, we'll put the dedicated server to use on other projects, and the content, after its removed from Google, we can find a way to re-purpose elsewhere.
