Dynamic URLs vs. Static URLs

URL is most important things for the website regarding SEO. There are two types of URLs: first is dynamic and second is static URL. The dynamic URL is a page addresses that if anyone makes a search or action on the pages then the page URL driven from database. But static URL is become very simple, file name become the URL of that page.

Dynamic website such as e-commerce stores, forums, content management system (CMS) site, blogging site like WordPress, Mambo and other website that’s pages comes create dynamically like.
http://xyz.org/money/Country.aspx?c_code=256&id=2451633
http://xyz.org/money/Country.aspx?c_code=256&id=2451634
http://xyz.org/money/Country.aspx?c_code=256&id=2451635
http://xyz.org/money/Country.aspx?c_code=256&id=2451636
http://xyz.org/money/Country.aspx?c_code=256&id=2451637
http://xyz.org/money/Country.aspx?c_code=256&id=2451638....

All of the above six URLs end with six different landing pages but when search engine tends to remove the information subsequent to the first offering character because the question (?) marks ultimately all six pages become identical as:
http://xyz.org/money/Country.aspx
http://xyz.org/money/Country.aspx
http://xyz.org/money/Country.aspx
http://xyz.org/money/Country.aspx
http://xyz.org/money/Country.aspx
http://xyz.org/money/Country.aspx
Your unique pages have become identical and according to search engine URL’s contains the duplicate name which not be indexed by search engines.
Sample Static page: http://xyz.org/money/Country.aspx Sample Dynamic Page: http://xyz.org/money/Country.aspx?c_code=256&id=2451635
Another problem with dynamic pages is keywords, because the dynamic pages generally do not have any keywords in the URL. The keyword is very important things for URL, if you are using the rich keyword in your URL (also domain name) then it’s good for your site according to search engine.

This is clear in recent study on URL the top three search engines Google, Yahoo! And MSN easily indexed your keyword used URL. Google search engine choose 40-50% of those with the keyword either in the URL or on with domain name, Yahoo! Show 60% and MSN show up to 85%.
