A dynamically generated webpage is created when your website uses a database or runs a script to determine which information to display. Your website may also use dynamically generated webpages if you use a content management system instead of creating webpages manually. As a tell-tale sign, dynamic web addresses often use symbols such as: ?, =, &, $, % and +.
Although dynamically generated webpages can be a convenient way to display information, search engines are not always able to "see" the content buried in database or script systems. Web spiders are often overwhelmed by dynamic databases and react by ignoring database information. Google, for example, limits the number of dynamic webpages it will index.
If your site uses dynamically generated webpages, try to create a static webpage URL for each possible query. Some content management systems can do this automatically. Alternatively, if you use an apache server, a web programmer can add a "mod_rewrite" code to help search engines index dynamic pages as if they were static pages. This is a relatively difficult code for a beginner – if you're just starting out it's probably best to hire someone who has experience. If you must continue to use dynamic content, keep generated URLs as short as possible.
