I’ve just discovered slugs.
No, not the garden variety, but the WordPress kind — Post Slugs.
(Note that I’m a newbie to WordPress having used it for less than a month).
You can read the WordPress explanation here. However I feel that Adesblog explains it better by giving an example of how to use it properly to benefit your blog.
I’m very excited about this feature because what this mean for me(and WP bloggers in general) is that I can have my Killer Titles(which may only have a faint allusion to the actual content) AND have the option to include more straightforward titles optimised for search engines.
