I have recently visited some website and there were no extension associated with the pages of that website like .html, .php, or .asp. It was like: www.websitename.com/anything/5667/ and many more ... what does it means how it is possible ?
The format that you have shown (websitename.com/anything/5667/) has sub-directories, which I have put in bold. If you have a index.html, index.htm in that subdirectory, then you can access it in the same way you would the main domain name. You don't have to put websitename.com/index.html into your browser, just like you don't have to put websitename.com/anything/5667/index.html into your browser. If there is no index file in the particular directory, it will display a list of files that have been uploaded into the directory in which you are trying to access. Also, with a script like Wordpress, there are no index.html files because it a php based script. I am not fluent in PHP but I do know that if I try to visit a sub-directory of mine (for instance, my last blog post http://flickorian.net/archives/reviewme ) using the /index.html file extension, it brings me to a 404 error page.
They are using mod-rewrite, it's like yourdomain.com/subdirectory/ or yourdomain.com/subdirectory/index.html?php?asp... I don't think that gonna helps your Serp either.
subdirectory pages donst need an y extension ... becoz they refer previous or root page extension if they are mentioned !
OR they use mod rewrite to do this: www.websitename.com/anything/5667/ converts to www.websitename.com/anything.php?id=5667 But you wont see the second link because its hidden from the praying eyes
If you use the folder/index file method, you would have to change all references to externall files in that index.html. Pictures would then be <img src="../images/banner.jpg" /> and if you create a folder in that folder then it would be <img src="../../images/banner.jpg" />. Why create more work for your self? Use modrewrite and put all files in the root unless you have a very good reason not to.
this thread has a few good methods on how to resolve the problem your having http://forums.digitalpoint.com/showthread.php?t=1142066
You must be a newbie to asp/php . They use the "url rewrite" technology like .htaccess files and "IIS url rewriter". It is a way to make search engine friendly url .
