Here is a start of my experiment with SEO friendly URLs.
http://hardkap.net/labs/pritlog48/blog
The html title of the page and the url now have the actual post title in them. This would really help in getting a good seo ranking. One major thing I have not addressed yet is that the posts should not have duplicate titles and the script does not handle this now.
This uses only a simple rewrite in htaccess. Everything else is handled from within the blog script.
Following is the htaccess
RewriteEngine on
RewriteRule ^blog$ blog.php
If someone does not have apache or htaccess facility, then they could still have almost SEO friendly URL's but instead of blog, it would be blog.php. But this should still be good.
Take a look at it and post your comments.
