Categories are also very search engine friendly. When you use Categories in your blog, there is a link on every one of your pages to your categories. Think about this: would you rather be #1 in search engines for March 2003, or for green widgets, one of main keywords of your site?

By using Category feature, you will eventually have hundreds of pages on your site with links to green widgets, black widgets, and orange widgets. All those backlinks to those keywords can result in much higher search engine rankings.

Another neat feature is that you can easily create an RSS feed for each of your categories. Then every time you post to your blog, it could be pinging Blog/RSS directories for each feed!

Compare that to putting up a new page on a traditional website. Even if search engines find your new page right away, it might be a month or two before it actually gets indexed and starts drawing traffic. It might be a long time before it enjoys a first page position for its keywords.

It's almost amazing how easy all this is with a well-structured blog like Wordpress with Categories enabled!

If your host doesn't already include Wordpress in scripts on your server, you can still pick it up at:

http://wordpress.org/

Then go to Wordpress Wiki for instructions on how to install it in 5 minutes:

Wordpress is free, open-source software. It is very simple to install, even for technophobes, and has a lot of online documentation. There are also many sites with free Wordpress add-ons and templates. I'm using a template for this blog that I picked up at Alex King's site:

The Wordpress Wiki is a wealth of information on all things Wordpress, including installation instructions, help files, a long list of template sites, and all kinds of hacks and extras you can use to modify your blog and make it original.

If you're a Wordpress user, another place to visit is Wordpress discussion forum:

If you're a new blogger, both Wordpress and Blogger are very user friendly. There isn't a long learning curve. And you won't have to learn any new technical tricks. Why not give one of them a try?
