Paying anyone to use submission software on your behalf is foolish. Not only will you learn nothing about what is needed to build a high search engine ranking, but you'll always need to pay again and again each time you submit another URL or wish to update your position. Even paying for inclusion within a search engine directly (like Yahoo Express) is not recommended. Yahoo charges a non-refundable $299.00 to review your submission. If they do not like your site - you lose. The chance they reject your site is fairly decent if submitted with errors or in an inappropriate category. Not to mention Yahoo is sourced by Overture and Google. If you use Overture you pay to rank well on Yahoo. Overture is excellent for all online sites to use. Also, if you rank well on Google, you will rank just as well with Yahoo. So don't pay Yahoo $299.00 to consider your site. Instead, try WebPosition Gold 2. It's the best way to list highly on the popular search engines.
