To have the maximum amount of audience visiting your website, it is very important that your website is accessible for search engines: just adding your site to Google is risking that only a small part of your site is appearing in its index since Google and Yahoo are only following links on pages.
Most of the new search engines support the usage of Sitemaps where you can serve all possible links you want to be indexed on a silver plate. This sitemap can dynamically be created by your website, partly based on your product database.
Another way to get more audience is the page of RSS feeds, where ypur content is presented on a new ways with out your web pages. A good example of RSS feed is the Google start page iGoogle, where your products can be displayed.
Search Engine Friendly
Make also your dynamic pages understandable by making the web page URL's more readable:
example: www.jmt.nl/event/rai looks much better than www.jmt.nl/?event=rai
Also displaying the product name and relevant keywords in the page title is also effective since Google weights page title and description as important.
this can be done with any link on your web page.
Search engine are becoming more and more complex and are constantly under development: Besides a good technical structure (optimization) also effective content and link popularity are important factors.
