how do I place my business in yahoo?

[Jake]

The Yahoo submission form can be found here: The big search engines all offer local listings, after your verify your address of a post card they may send, you can customize and enhance the page they setup for you:

http://listings.local.yahoo.com/

Google gets about 65% of the searches:
http://google.com/placesforbusiness

And don't forget Bing
http://www.bing.com/businessportal/

It probably helps to also have a company web site mentioning the address, the search ranking of the site may reflect on the position of your local listing. You could use a free host with a paid company domain name costing about $12/yr
