1. Dynamic URLs vs. Static URLs
The Issue at Hand
Websites that utilize databases which can insert content into a webpage by way of a
dynamic script like PHP or JavaScript are increasingly popular. This type of site is
considered dynamic.( http://www.mumbaiseo.co.cc/Dynamic-URLs-vs-Static-
URLs.html
) Many websites choose dynamic content over static content. This is because if a website
has thousands of products or pages, writing or updating each static by hand is a
monumental task.
There are two types of URLs: dynamic and static. A dynamic URL is a page address that
results from the search of a database-driven web site or the URL of a web site that runs a
script. In contrast to static URLs, in which the contents of the web page stay the same
unless the changes are hard-coded into the HTML, dynamic URLs are generated from
specific queries to a site's database. The dynamic page is basically only a template in
which to display the results of the database query. Instead of changing information in the
HTML code, the data is changed in the database.
But there is a risk when using dynamic URLs: search engines don't like them. For those
at most risk of losing search engine positioning due to dynamic URLs are e-commerce
stores, forums, sites utilizing content management systems and blogs like Mambo or
WordPress, or any other database-driven website. Many times the URL that is generated
for the content in a dynamic site looks something like this:
http://www.somesites.com/forums/thread.php?threadid=12345&sort=date
A static URL on the other hand, is a URL that doesn't change, and doesn't have variable
strings. It looks like this:

Static URLs are typically ranked better in search engine results pages, and they are
indexed more quickly than dynamic URLs, if dynamic URLs get indexed at all. Static
URLs are also easier for the end-user to view and understand what the page is about. If a
user sees a URL in a search engine query that matches the title and description, they are
more likely to click on that URL than one that doesn't make sense to them.
A search engine wants to only list pages its index that are unique. Search engines decide
to combat this issue by cutting off the URLs after a specific number of variable strings
(e.g.: ? & =).
For example, let's look at three URLs:
http://www.somesites.com/forums/thread.php?threadid=12345&sort=date

2. http://www.somesites.com/forums/thread.php?threadid=67890&sort=date
http://www.somesites.com/forums/thread.php?threadid=13579&sort=date
All three of these URLs point to three different pages. But if the search engine purges the
information after the first offending character, the question mark (?), now all three pages
look the same:
http://www.somesites.com/forums/thread.php
http://www.somesites.com/forums/thread.php
http://www.somesites.com/forums/thread.php
Now, you don't have unique pages, and consequently, the duplicate URLs won't be
indexed.
Another issue is that dynamic pages generally do not have any keywords in the URL. It is
very important to have keyword rich URLs. Highly relevant keywords should appear in
the domain name or the page URL. This became clear in a recent study on how the top
three search engines, Google, Yahoo, and MSN, rank websites.
The study involved taking hundreds of highly competitive keyword queries, like travel,
cars, and computer software, and comparing factors involving the top ten results. The
statistics show that of those top ten, Google has 40-50% of those with the keyword either
in the URL or the domain; Yahoo shows 60%; and MSN has an astonishing 85%! What
that means is that to these search engines, having your keywords in your URL or domain
name could mean the difference between a top ten ranking, and a ranking far down in the
results pages.
The Solution
So what can you do about this difficult problem? You certainly don't want to have to go
back and recode every single dynamic URL into a static URL. This would be too much
work for any website owner.
If you are hosted on a Linux server, then you will want to make the most of the Apache
Mod Rewrite Rule, which is gives you the ability to inconspicuously redirect one URL to
another, without the user's (or a search engine's) knowledge. You will need to have this
module installed in Apache; for more information, you can view the documentation for
this module here. This module saves you from having to rewrite your static URLs
manually.
How does this module work? When a request comes in to a server for the new static
URL, the Apache module redirects the URL internally to the old, dynamic URL, while
still looking like the new static URL. The web server compares the URL requested by the
client with the search pattern in the individual rules.
For example, when someone requests this URL:
http://www.somesites.com/forums/the-challenges-of-dynamic-urls.html

3. The server looks for and compares this static-looking URL to what information is listed
in the .htaccess file, such as:
RewriteEngine on
RewriteRule thread-threadid-(.*).htm$ thread.php?threadid=$1
It then converts the static URL to the old dynamic URL that looks like this, with no one
the wiser:
http://www.somesites.com/forums/thread.php?threadid=12345
You now have a URL that only will rank better in the search engines, but your end-users
can definitely understand by glancing at the URL what the page will be about, while
allowing Apache's Mod Rewrite Rule to handle to conversion for you, and still keeping
the dynamic URL.
If you are not particularly technical, you may not wish to attempt to figure out the
complex Mod Rewrite code and how to use it, or you simply may not have the time to
embark upon a new learning curve. Therefore, it would be extremely beneficial to have
something to do it for you. This URL Rewriting Tool can definitely help you. What this
tool does is implement the Mod Rewrite Rule in your .htaccess file to secretly convert a
URL to another, such as with dynamic and static ones.
With the URL Rewriting Tool, you can opt to rewrite single pages or entire directories.
Simply enter the URL into the box, press submit, and copy and paste the generated code
into your .htaccess file on the root of your website. You must remember to place any
additional rewrite commands in your .htaccess file for each dynamic URL you want
Apache to rewrite. Now, you can give out the static URL links on your website without
having to alter all of your dynamic URLs manually because you are letting the Mod
Rewrite Rule do the conversion for you, without JavaScript, cloaking, or any sneaky
tactics.
Another thing you must remember to do is to change all of your links in your website to
the static URLs in order to avoid penalties by search engines due to having duplicate
URLs. You could even add your dynamic URLs to your Robots Exclusion Standard File
(robots.txt) to keep the search engines from spidering the duplicate URLs. Regardless of
your methods, after using the URL Rewrite Tool, you should ideally have no links
pointing to any of your old dynamic URLs.
You have multiple reasons to utilize static URLs in your website whenever possible.
When it's not possible, and you need to keep your database-driven content as those old
dynamic URLs, you can still give end-users and search engine a static URL to navigate,
and all the while, they are still your dynamic URLs in disguise. When a search engine
engineer was asked if this method was considered "cloaking", he responded that it indeed
was not, and that in fact, search engines prefer you do it this way. The URL Rewrite Tool
not only saves you time and energy by helping you use static URLs by converting them

4. transparently to your dynamic URLs, but it will also save your rankings in the search
engines.
