Major Search Engines and Directories to submit your site

I have been receiving a lots of emails from thousand of internet professionals and/or search engine optimizers asking for the major & good search engine and directories to add their own or client website.

I thought to publish a list of the engines & directories here in my blog.

GoogleYahoo!AltaVista Lycos Excite HotBot AllTheWeb
Open Directory Project (DMOZ)
Baidu
Northern Light
LookSmart
About.com
MSN Search
Refdesk.com
Teoma
Alexa
Daypop
AOL Search
Snap
InvisibleWeb

I would also request you to perform a simple search on Google for search engines & directories and you will receive a list of all related sites.

I hope this will help.
