Definition of Dynamic Pages : Dynamic pages are the pages generated "on-the-fly" from a database. It is also known as database-driven pages. PHP, Perl, ASP, etc are using to generate dynamic pages. It is difficult for the search engines to read the dynamic pages. It is generated when user select variable. It is not possible for search engines to select those variables and this reason these pages cannot indexed. Dynamic URL's contains strings like &, %, ? and due to these characters problems starts for the search crawlers to read the content. But it is possible to index the dynamic pages also. Here, I am writing the way through which a dynamic page can be readable by the crawlers : a) Place links of the dynamic pages on static pages. Further it can be submitted in search engines manually. Most of the dynamic pages will indexed by the search engine by this way. b) Coldfusion and other softwares are available which can replace special characters like ?, %, & with alternative text. c) Using help of CGI/Perl, we can convert query string in the url with suitable text. Path_Info and Script_Name are environment variables which contains complete URL including strings in dynamic pages. d) Web hosting company also provides module with Apache software that can convert dynamic URL into urls that can be indexed by search engines. The mod_rewrite available for Apache that converts requested url into search engine friendly urls.
I always had this question on my mind because as static websites bring continuous changes in their pages, so how they do it for static sites. Kajal or 2005 SEO whosoever it is to give the information it helped a lot and now I can work partially on static sites. Is there any other points to be kept in mind kindly update me that also.
Its better to categorized your products on the base of Color, Size and Design and make static web pages for each categorized section to list your products and promote your static page to drive traffics on product listing pages. Make dynamic web pages for each product and rewrite their URLs using .htaccess. and display meta tags dynamically for all dynamic product pages.
