Any google expert can put some light into this? I'v been working a small WIKI for some months now, started back in november, and for many months, I had an average of 25 unique visitors per day, now, on April 19th, I started to get a lot of hits from google search, basically I started ranking good for almost every article in my wiki, growing all the way to almost 300 uniques on May 5, but after that, on may 10th, I'm back to 25 visits, and I rank like shit on all keywords like it was before.. why will google do this?
