Which SEs should I opitmize my site for?

My first round of SEO is a success, at least for Google, but I still don't get any traffic from other search engines. I want to start the second round of SEO. I was wondering which SEs are worth optimizing for. Thanks!

Oh, I'm talking about SEs with spiders, not Yahoo and LS.

You are doing well in Google so the rest is simply a matter of time.

Optimize for one, you already optimized for all of them. At least, that's how I and others do it.

For my first SEO plan, I merely exchanged links with other USB sites, and submitted to directories DMOZ, Yahoo. Now I have two Yahoo listings and one DMOZ listing. Just like that. I did nothing more. I may have played around a little with meta tags on my homepage, but my SEO plan doesn't really include homepage optimization due to the fact that my site covers too many topics. I tried to optimize for each sub-section (eg. USB TV, USB Cables, USB Hubs) instead.

For my second round of SEO, I would like to continue with the directory submission, and to optimize meta tags for popular sections on my site. However, I don't know which search engines are worth optimize for. I may need to hire a SEO expert to do the job.
