Do the major directories like BOTW, Yahoo, Business.com, JoeAnt, and the other major directories accept submission of additional pages of your website. For example, if you have submitted toys.com and it is listed already. Can you also submit toys.com/electronic and pay the fee again to get that page listed?
Cant speak for all directories but in my experience most directories allow multiple submission of different pages when you pay for the service. Free ones generally do not and although I have not tried big reputable Directories like the ones you list probably wouldnt allow multiple listings.
Some directories will allow you to post deep links and even specify your own Title/anchor text. The most valuable directories, however, generally use your domain/company name as your listing title and restrict you to just your root domain. A good guide on the strength of the directories out there, and the relative charges incurred, can be found at avivadirectory.com/strongest-directories/- very nice guide!
Yup they will accept them and I think its good to do it. You can spread the value around your site a little rather then concentrating it all on the homepage. Good Luck
Most major directories only allow the parent link to be listed.. you will have to find out individually from them.
Big point has to be, which I think a lot of webmasters often miss - just because you have to pay a big fee doesn't mean it's an authoratitive directory. The prominence and value of directories in the link builder's toolkit has drastically changed over the past few years, so be sure to get some good advice before throwing money at this link building method.
