Specifically, Google will not index pages that include "&id=" in the URL string,
whether you actually use session ids or not. This means that if you have a dynamic
site that generates multiple-parameter URL strings, you should strongly consider
changing your server code to use a string other than "id" for generating dynamic
URLs. Don’t use anything that uses "id" anywhere in the string, including sessid,
rid, pid,id1, etc.
A simple solution is to create static pages with hard-coded links to your most
important dynamic pages whenever possible. You can create a series of sitemap
pages just for this purpose. Yes it can be tedious if you have hundreds or thousands
of products but it is worth the effort. You want to make it as easy as possible for
Google to find all your important pages. This has the added benefit of helping your
visitors find a specific product page – be sure and use the product name or keyword
in the link text.
URL Rewriting
There more advanced technique involves installing a script on your server that
changes a dynamic URL to a static page, whereby each parameter name is
translated to a folder name. This method varies by server platform and is something
a more experienced webmaster should implement. For the Apache platform, it can
be as simple as creating a .htaccess file that contains regular expressions. Do a
search on Google and you’ll find a number of ways to do URL rewriting (also called
mod rewrite or server rewriting).
All search engines prefer static pages over dynamic pages. If you have a large site
with lots of dynamic pages, you should consider URL rewriting, as dynamic pages
can take months longer to be indexed and then ranked in Google. And once indexed,
Google will not re-crawl dynamic pages as often as static pages.
Keywords in File Names
Although not an important factor, Google does look to see if keywords are used in file
names for your web pages, but the overall influence on your ranking is very minute.
When naming files, separate each word with a hyphen, otherwise Google will not be
able to recognize the phrase and will think it is a single word.
As a general rule of thumb, don’t use more than two hyphens, it looks spammy and
Google may take a closer look at your site for other possible issues.
