Process for SEO of Dynamic Website

What process should we follow to optimize the dynamic website contains more than 5k pages.

As typical SEO process is to either use mod_rewrite or use xml file to optimize the pages.

But here I m looking for a clear process to define how to begin and what will be impact after implementing and how to implement?

I am working on it and will soon write more on this.

Waiting for your support on the same.

1) Keep URL variables to a minimum
Definitely no more than 3, and ideally just one variable in the URL query string. The more you have, the more potential problems you'll get with crawling.

2) Maintain consistent URLs
If you do have more than one variable in the query string, make sure that they always appear in the same order. ?p=1&c=2 is seen as a different URL to ?c=2&p=1

3) Don't be lazy and repeat page elements
Make sure that the database has enough columns to store all the different page elements, eg title, meta description (if you're going to use it), h1 tag if you use it, etc.

All too often the script is designed only to store the page content, leaving the same titles etc across all pages. That's not a good thing.

4) Write the backend code properly
This applies whether or not you're using mod_rewrite (or Windows equivalent). Sanitize any input properly, and write decent error handling. If the variable isn't what's expected, or is but there's no corresponding row in the database, make sure that the page returns a 404 header, together with a "sorry, we couldn't find the page you were looking for" type message for the user.

All too often you come across sites where the only error handling is done by the server throwing it's metaphorical hands up in the air and throwing a fit, whilst telling the world details about your site you really don't want them to know.


Static URLs

It seems every time someone mentions optimising dynamic pages, someone else pipes up with "static URLs" as if it's some golden panacea to well ranked dynamic pages (see above). It's not.

Yes, it means you can get your keywords in the URL, but that's a very very minor advantage, and won't directly bring you any visible benefits on competitive search terms. The main benefit would be from people linking to you with the URL itself as the anchor text. If these pages are unlikely to be linked to individually, you wouldn't get that benefit anyway.

The disadvantages are that you're going to have to invest time or money in recoding your pages, especially on a Windows server where implementing ISAPI Rewrite is not as easy as mod_rewrite on an Apache server.

It also means changing all your existing URLs, so you'll have to 301 redirect them and still experience disruption whilst the search engines index the changes. You'll also need to change all the internal links, which may or may not be a quick task depending on the size of the site.

If you're starting from scratch, then rewriting URLs to appear as static pages is something I would recommend, since it's easy to do at that stage. For an established site, it's not such an easy decision, and there are arguments for and against.


Conclusion
A dynamic page has as much opportunity to rank as a static page. Neither is better nor worse than the other. In many ways, on-page optimisation of a dynamic site is easier if the back end is built with SEO in mind, since it forces you to consider, and give thought to, the individual page elements.a
