"Every business wants high search engine rankings. Why? Because search engines deliver customers who have already self-selected themselves through their searches. A visitor from a search engine is many times more likely to be an actual prospect, a real lead, than someone targeted through demographics. So you optimize your website for Google, right? And Yahoo and Bing? But have you stopped to think of some of the alternative search engines that don't call themselves "search engines"? Places your target market is searching?"
The post then goes on to list various types of non-search-engine search engines and in what situations to optimize/engage through them. The post is at http://thesocialrobot.com/2010/05/ho...earch-engines/
I do plan to write more on this, so any feedback (here or there) would be appreciated.
