The more I use WordPress, the more I love it. It has 2 very important features that Blogger doesn’t yet support.

Number 1, you can set up WordPress to automatically ping all the RSS and blog feed directories every time you make a post. This is a very powerful feature if you want your blog to get a lot of traffic right away. On top of that, you’ll be quickly developing backlinks to your blog almost automatically.

Think about how long it can take you to build a regular site, get the search engines to index it, get backlinks to improve your listings, and then start getting traffic. A blog like WordPress can do all that “grunge” work for you automatically.

Number 2, WordPress allows the use of Categories. Categories are a very powerful way to improve the structure of your site both for human visitors and for the search engines.
Let’s say the topic of your site is Widgets. You could create a Category for black widgets, one for orange widgets, and one for green widgets.

Now when you add posts to your blog, you can choose which of your categories your post belongs to. Now your blog will archive your past posts not only by their month and date, as Blogger does. But also by Category.

So if you have a visitor who is especially interested in green widgets, they can easily find all your posts on green widgets. They don’t have to go through your entire archives to find them. With a blog that has been around for awhile and has hundreds of posts, that would be pretty discouraging. Using Categories makes it very easy.

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 the search engines for March 2003, or for green widgets, one of the main keywords of your site?
By using the 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 the Blog/RSS directories for each feed!
Compare that to putting up a new page on a traditional website. Even if the 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.
