Microsoft Network Web Search
Open Directory Project - DMOZ.
I have highlighted the top sites to get listed with. Yahoo can produce as much as 2/3rds of your web traffic. LookSmart feeds MSN and many other search engines and is a growing part of the search engine market. DMOZ feeds most all of the other search engines and many not listed, which literally will get you into hundreds of search engines. Get those listings correct are important and we always do those by hand. If you have the money we also recommend the pay listing services from Yahoo and LookSmart. It costs more but you will get quick results.
If you have a site that is traffic poor, contact us for pricing of this service. WE GUARANTEE RESULTS! and it costs less than you might think, especially when you get many times more traffic to your site by someone who will be here. We can also help you with web site promotions.
