Do You SEO For A Specific Engine?

I was just chatting with someone on ICQ about how our search engine listings had changed in the past few days and wondered if you folks did your SEO work for a specific engine over another?

For me i stopped worrying about a couple of search engines a few years back and now concentrate on 1 or 2 specifically over trying to do my SEO work for mulitple engines.

So which search engine do you folks concentrate your SEO efforts on?

I have honestly never tried to make anything seo friendly. If it happens, great.

no, just text, keywords, links - but I just seem to get google traffic and about 1-2% of other SEs.... strange

i get some good search terms with goggle but i really dont know enough about how to work my pages yet to do specific works for google i am learning slowly though and hope to be an expert at it soon with some practice :)
