No way, you made your site BETTER and it got lowered in rankings? Now you know why some webmasters don't fight the good fight and simply resort to mass spam of all tactics available to game search.

In all seriousness however, my advice is to stay the course. If Google can't realize you IMPROVED your site for your visitors then it looks badly upon them, not you.
