A few days ago my PR got dropped from 2 to 1. I am not worried about that. But yesterday when I was looking at the sitemeter data, I saw there were entries from google.com and they seem to have been searches for a specific post in my site. It was something like site:xxxxxxxx/abc-post-aug-23. Does anybody know what this means? Why is google showing up in my sitemeter tracking with weird command searches? Thanks.
