How many unique visitors does your site/s receive a month? Plus where do most come from (i.e. search engines, article submission sites, tell a friend scripts, directories, other sources etc.....) Be curious on the results... For myself: 19,000 uniques 60% - Search Engines (Google and MSN) 39% - Regular visitors - direct URL 1% - Other sources
It's our experience that surfers from Y! as well as MSN SE's actually snoop around your site more providing a higher CTR than surfers from Google.
