With all the PPC and paid listings Ask has never really struck me as a very pleasant search engine to use - however it is one of the biggest in the UK and need to be considered. Some people who use Ask Jeeves say that it is the best around and swear by it.
So what overall strategy is best for Ask now that Teoma is in.
A Teoma listing would be nice but the teoma spider avoids submissions and few of my sites seem to get in.
Direct Hit is based on click pop and can be addressed slowly.
