I was planning on submitting to Yahoo later this month and was interested to learn just how much you can actually submit on one submission?
Meaning, if i had www.widgets.com which consisted of 50 pages but also had www.blue-widgets.com and www.red-widgets.com linked clearly from my HOME PAGE of the submitted site, will the Yahoo people index that as well (not in the directory, just a crawl) so that it would immediately show up in Yahoo/Google Search Results as well?
Yahoo is a directory, it includes sites that are submitted to it, period.
Google, on the other hand, is a crawler, and it will include all pages that it finds while crawling.
So the answer to your question is both yes and no. Yahoo will only include widgets.com in their directory (assuming they decide to include it), but Google will follow the links and include all three (plus all their pages).
