Submissions to Yahoo must follow their submission guidelines at
http://help.yahoo.com/help/us/url/ or they will be rejected. Sites must not contain broken links or be under construction, thay must contain unique content and must support different browsers and systems.
A submission to Yahoo is made by finding the most appropriate category for your site then clicking the 'Suggest a Site' link at the bottom of the page. A multi-page form must be completed and the submission may then be reviewed by an editor. You will know if your site is successful as Yahoo sends an acceptance e-mail. If you haven't had an acceptance e-mail within 5 weeks of submission then submit again. Consider if the original submission was correct. Common reasons for rejection include not having the official company name as the Title, submitting to the wrong category and not adhering to the guidelines.
BizExpress submissions are a fast track review system which, at a cost of $199, guarantees an editor will look at the site within 7 working days. It does not guarantee inclusion and the submission must still conform to the guidelines. There is an appeals process if the site is rejected or placed in the wrong category but ultimately Yahoo will choose whether to list a site or not and you are only paying for a review, not a listing.
Before submitting your site is is essential to thoughly read the Yahoo guidelines and to chose the most appropriate category for submission. It is well worth practicing on the forms before actually submitting your site as this will allow you to identify the information required and consider what to enter at each stage.
