Dynamic websites are not preferred over static websites as they DO NOT have pages of their own. About 80% of the content are randomly selected by the server and put on the website each time it loads. But, I have seen dynamic websites performing very well in search engines because of the optimization.

Here are some tips to optimize your Dynamic website for high search engine rankings:

#1.Generate a sitemap using http://sitemapgenerator.com
and submit it to Google Webmaster Tools and Yahoo.com. DO NOT skip this step even if your website has more than 100 pages on it.

#2. Get back links to the inner pages of your website from other websites of the same niche or link directories, classified ads etc.

#3. You can even convert dynamic pages to static by URL re-writing techniques.

#4. DO NOT use session IDs especially when people are not logged in.

#5. You can even create your own .html or .htm static page by taking the html code in the “View Source option” available in the dynamic website.

NOTE: The more your website pages are indexed the better will be the rankings of your website.
