I haven't recovered from February. If anything, things have become worse.
Google was always 44% of my referrals, +- 1.5% or so. After 2/24, it dropped to 28% and held steady. It's now dropped to 25% in the last week or two.
I'm making changes, but the changes to each page are taking me a day or more and, with 2000+ pages to do, I suspect it's going to be a long time before I can measure any changes for the better.
