Number of links from other sites to yours is used as an important ranking criterion for search results. It is very important to negotiate links with other good sites. One way to get links is to provide high quality, original content. Difficult and time consuming, but it will also serve to attract visitors directly, function as one more way to list your site with search engines and possibly even directories if the content is truly original, of wide interest, and constitutes a large section of your website. Automatic page generation and submission can actually do you a good deal of harm.
Most experts submit one page at a time, manually.
This is both good and bad. The bad part is that you may get a reviewer who makes hamburger of your beautifully written description. The good part is that you can ask for revisions of the reviewer's first re-write of your submission. Make sure you are submitting in the right category. Above all, your short phrase or two must be so attractive that searchers select your listing rather than another one on the page.
