Dynamic websites are websites whose pages are “on the fly generated. Generated Unlike static pages (mainly. htm. Html pages), dynamic pages when a user initiated an action that particular page.

An example of a dynamic URL

http://www.bbc.co.uk/cgi-bin/search/results.pl?q = “Dynamic Web Sites & tab = news & go = homepage

As in the above example from www.bbc.co.uk, the dynamic part (ie unit) of the URL as the driver is required to change the part after the question mark (?)

What are the problems search engines face indexing Dynamic URLs?

1. Search engines often seen as a dynamic URL as an infinite series of links.

2. Since dynamic URLs find maximum application in online shopping, there is a possibility of including a session for a specific page id. Since the session ID to change the current page must be indexed to the search engine spiders are an infinite number of copies of the same page, which is a Herculean task for them.

3. Continuation of the same logic in Item No. 2, presents the same indexing dynamic pages could overload the servers of the search engines and therefore prevent the search engines to present the most important information in the fastest time possible.

Here’s what Google says about indexing of dynamic websites -

Reasons your site may not be included: Your pages are dynamically generated. We are able to index dynamically generated pages. However, because our web crawler can easily overwhelm and crash sites, dynamic content limit, we are the number of dynamic pages we index. (Source – http://www.google.com/webmasters/)

What are the options you need to do a search engine spider index your dynamic URL?

1. The use of software – Exception Digital Enterprise Solutions (http://www.xde.net) provides software that can change dynamic URLs to static images. Appointed XQASP, it removes the “?” replace the query string and by “/” so that search engines to index dynamic content.

Example -
http://www.my-online-store.com/books.asp?id=1190 will change
http://www.my-online-store.com/books/1190.

The latter is a static URL, it can easily be indexed by search engines.

2. With CGI / Perl – One of the easiest ways to get your dynamic sites indexed by search engines is using CGI / Perl. PATH_INFO or SCRIPT_NAME is a variable in a dynamic application that contains the full URL (including query string information). To resolve this problem, you need a script to pull all the information the query string and the rest on the same information to write to a variable. You can then use this variable in the URL.

Example – http://www.my-online-store.com/books.asp?id=1190

If you CGI / Perl, the request part of the URL is assigned to use a dynamic variable.
So in the example above? Id = 1190 “is assigned to a variable, such as” A “. The URL dynamuc http://www.my-online-store.com/coolpage.asp?id=1190
through http://www.my-online-store.com/books/A CGI / Perl, which can be indexed easily by search engines.

3. Re-configure your Web server -

(I) Apache Server – Apache has a rewrite module (mod_rewrite) which allows you to turn URLs with query strings in the URL, which can be indexed by search engines. This module is not installed by default with Apache software, you should check with your web hosting company for the installation.

(Ii) ColdFusion – ColdFusion, you must configure your server so that the “?” replaced in a query string by ‘/’ and pass the value to the URL.

4. Create a static page, a number of dynamic pages -

This approach is very effective, especially if you have a small online shop selling some of their products online. Simply create a static page links to all your dynamic pages. Optimize this static page for search engines. Include a link title for all categories of goods where appropriate “alt” tag for product images and descriptions of the product popular keywords for your company includes relevant (you can look for keywords for your site by http://www.wordtracker. Com). Email this static page with all the dynamic pages in various search engines, such as search engine registration.

Such as Amazon.com, Earth’s Biggest Bookstore, faces the issue of indexing dynamic URLs?

A Google search for Internet marketing books, gave a result that you directly to that page at Amazon dynamics: http://www.amazon.com/exec/obidos/ISBN=0395683297/103-0475212-8205437.

Since the above URL contains no query strings, all search engines can index Amazon.com products. Amazon.com uses this method to its range of products to be indexed by search engines. This is very important for Amazon, there is an online bookstore, it is quite natural for them to adopt dynamic URLs, but it is equally important for them to do their index dynamic URLs search engine friendly.

Conclusion

Even a couple of years have not indicated most of the major search engines dynamic URLs, which often prevents the best search engine for online stores. Start with Google index dynamic URLs a few months will change the situation in the coming days. This is even more than Google numero uno position is now Microsoft’s MSN (developing its own search engine) and Yahoo recently acquired Overture threatened, the largest player in the industry PPC search engine.
